Extremely skilled and helpful.

I’ve used Ian and his teams services for a while now and I’ve always found the workmanship to be of the highest quality, all his team are extremely skilled and helpful.

We would certainly recommend this company

We were very pleased with the quality of the INS Air Conditioning units. The fitters were punctual and fitted the units over two days. Ian explained everything to us and we are happy with the results. We would certainly recommend this company to anyone who was interested in having air conditioning units installed.

High standard

Polite, showed up on time, wore overshoes and did exactly what they said they would. Work looks to be completed to a high standard and as they are Mitsubishi certified, the air conditioning units have a 5 year warranty on them.

This is the text area for this paragraph.

Ian came highly recommended by my neighbours who had air conditioning fitted in their master bedroom last summer and subsequently a further two bedrooms. Ian was professional from the quote to the completion of the works. He was able to schedule the installation quickly and the work was completed in a day.

Friendly, courteous, polite

Ian was very accomodating in arranging a time for installation, the installation team were friendly, courteous, polite and extremely efficient working through the hottest days of the year! The quote was reasonable and we had lots of options presented to us based on Ian's experience and advice.

Highly recommended

After the temperatures last summer we decided to finally get an aircon unit in the bedroom after considering it for a few years. Ian came back very quickly on our initial enquiry and was able to give us a budgetary price for an installed Panasonic TZ on the phone, which was very helpful and very reasonable

Excellent service - would definitely recommend.

They arrived as expected and carried out the job which only took a few hours. They were extremely tidy too and took time to talk us through the controls for the new unit. Excellent service - would definitely recommend.

They were pleasant to deal with

Ian O'Toole and his colleague (also Ian) managed the work efficiently and professionally. They were pleasant to deal with, explained the options, and made sure they completed the work to our complete satisfaction. We would definitely recommend INS for similar work.

The Ultimate Guide to Choosing the Right Air Conditioning System for Your London Home

By Rosie Bossert • November 3, 2025

When summer rolls into London, it’s no secret that homes across the city can quickly become uncomfortably warm — especially modern flats and well-insulated houses. That’s when air conditioning stops feeling like a luxury and starts feeling like a necessity. But with so many options on the market — from split systems to ducted setups, portable units to multi-room solutions — it’s easy to feel overwhelmed. The good news? Choosing the right air conditioning system for your home doesn’t have to be complicated. In this guide, we’ll walk you through everything you need to know: from understanding the types of systems available to identifying which option best suits your home, lifestyle, and budget. 1. Understanding the Main Types of Air Conditioning Systems Before you start comparing brands or prices, it’s important to understand the key types of air conditioning systems available in London homes. Each has its own strengths, depending on your layout and comfort goals. Split System Air Conditioning This is the most common choice for London homeowners. It consists of one indoor unit (mounted on the wall) and one outdoor unit. It’s ideal for cooling single rooms such as bedrooms, lounges, or home offices. Affordable and energy-efficient Quick to install Quiet operation Perfect for smaller homes or flats where you only need cooling in one or two areas. Multi-Split System Air Conditioning A multi-split system connects several indoor units to a single outdoor unit. Each room can be controlled independently, giving you complete flexibility. Great for medium to large homes Sleek, minimal outdoor footprint Individual room temperature control This option suits London homes that want tailored comfort in multiple rooms without cluttering the exterior. Ducted Air Conditioning For those wanting a seamless, whole-home cooling solution, ducted systems are unbeatable. They use concealed ducts to deliver conditioned air throughout the property, controlled via a central thermostat or smart home system. Even temperature distribution Hidden design with minimal noise Adds long-term property value Ducted systems are ideal for full renovations, new builds, or high-end homes where design and comfort go hand in hand. 2. Match the System to Your Home and Lifestyle Choosing the right system is about you — your space, your habits, and your comfort priorities. Ask yourself: How many rooms do I need to cool? Do I want individual temperature control? Is aesthetics important? What’s my budget for installation and running costs? For instance: A compact flat in North London might only need a single split system in the living space. A detached house in West London could benefit from a ducted system for whole-home comfort. A home office setup could use a portable or wall-mounted system for flexibility and quick installation. 3. Energy Efficiency — Save Energy, Save Money With London’s growing focus on sustainability, energy-efficient air conditioning is a smart investment. Look out for these features when choosing your system: Energy ratings: Aim for A++ or A+++ efficiency. These systems consume less power and are environmentally friendly. Inverter technology: Instead of turning on and off constantly, inverter-driven systems adjust power output to maintain consistent temperatures — saving electricity and reducing wear and tear. Eco-friendly refrigerants: Modern units use R32 refrigerant, which has a lower environmental impact compared to older gases. Pro Tip: Over the lifespan of your system, energy-efficient models can save hundreds of pounds in electricity costs — especially in homes using air conditioning year-round for both heating and cooling. 4. Don’t Overlook Noise Levels and Design London is a bustling city — so your home should be a calm retreat. When choosing your air conditioner, pay attention to noise ratings. Indoor units can be as quiet as 19–25 dB — that’s softer than a whisper. Outdoor units can be strategically placed or shielded to avoid disturbing neighbours. Design options now include ultra-slim and minimalist wall units that blend into modern interiors. If you live in a listed building or apartment complex, check any restrictions before installation — an experienced installer like INS Air Conditioning can help with the necessary permissions and placement advice. 5. Budgeting: What Does Air Conditioning Cost in London? Air conditioning installation in London varies depending on your system type, property layout, and number of rooms. Here’s a general guide: Single split system: £1,500–£2,000 (installed) Multi-split system: £2,500–£4,500 Ducted system: £5,000+ (depending on size and complexity) Remember to factor in: Running costs (based on energy rating and usage) Annual servicing (to maintain efficiency and warranty) Manufacturer warranty (most offer 3–5 years with regular maintenance) An experienced installer will assess your home and provide a tailored quote — ensuring you get the right system without overspending. 6. Installation and Aftercare Even the best system won’t perform properly if it’s not installed by a qualified engineer. Incorrect installation can lead to inefficiency, higher energy bills, and even premature breakdowns. At INS Air Conditioning , our F-Gas certified engineers ensure every system is installed safely, efficiently, and in line with the latest UK regulations. We handle: Electrical setup Refrigerant management Airflow testing and system balancing Once installed, regular maintenance is essential. We recommend scheduling a service twice a year — once before summer, and once before winter — to keep your unit clean, efficient, and performing like new. 7. Smart Features to Consider Modern air conditioning systems can integrate with your smart home setup, allowing you to control temperature, schedule cooling times, and monitor energy use right from your phone. Look for: Wi-Fi connectivity Smart thermostats Voice control compatibility (Alexa, Google Home) These features add convenience while helping you manage energy use more effectively — ideal for tech-savvy London homeowners. 8.

How Regular Air Conditioning Maintenance Saves London Businesses Money Year-Round

November 3, 2025

Running a business in London comes with enough challenges — from managing staff and customers to keeping costs under control. But one area many businesses overlook is their air conditioning system . Your AC does more than keep the air cool; it maintains comfort for employees, protects valuable equipment, and can even impact productivity. Yet, without regular maintenance, it can also become one of your biggest hidden expenses. In this article, we’ll explain how regular air conditioning maintenance in London can save your business money all year round — and why a simple service plan could be one of your smartest investments. 1. Prevent Costly Breakdowns There’s nothing worse than a broken air conditioner in the middle of a heatwave — especially when your business depends on customer comfort or equipment cooling. Unplanned breakdowns don’t just disrupt operations; they cost money. Emergency callouts, replacement parts, and lost productivity can quickly add up. Regular maintenance allows engineers to: Spot worn or failing components early Replace filters before they become clogged Check refrigerant levels for efficiency Ensure the system is operating safely A simple biannual service can help prevent the majority of costly breakdowns — saving hundreds, if not thousands, in emergency repairs over the life of your system. 2. Lower Energy Bills with a More Efficient System An air conditioning system that’s not maintained properly has to work harder to achieve the same level of cooling. Over time, dirt build-up, blocked filters, and low refrigerant levels can reduce efficiency by up to 30% . That means you’re paying more for less cooling — and wasting energy in the process. Regular maintenance ensures your system is: Operating at peak efficiency Properly calibrated for your space Using energy-saving inverter technology effectively For many London businesses, simply keeping up with routine servicing can reduce energy bills enough to pay for the maintenance itself . 3. Extend the Lifespan of Your Equipment Commercial air conditioning systems are a significant investment. Regular maintenance helps protect that investment by keeping every component — from compressors to fans — in top condition. Without proper care, systems may need replacing years earlier than expected. But with consistent maintenance, your unit can last well beyond its standard lifespan. Think of it like maintaining a company vehicle: a small investment in servicing prevents major breakdowns and keeps things running smoothly. 4. Maintain a Comfortable and Productive Workplace Comfortable employees are productive employees. Studies show that workplace temperature and air quality directly impact focus, morale, and overall performance. A well-maintained air conditioning system ensures: Consistent temperatures across offices or retail spaces Better air quality by removing dust and allergens A pleasant environment for staff and customers alike In London’s competitive business landscape, creating a comfortable, professional atmosphere can make a real difference — especially for client-facing environments like restaurants, salons, or retail stores. 5. Protect Sensitive Equipment and Inventory For some businesses, air conditioning is about more than comfort — it’s about protection. Data centres, server rooms, and even retail stockrooms rely on stable temperatures to keep technology and products safe. Regular maintenance prevents fluctuations that could damage equipment or trigger costly downtime. At INS Air Conditioning , we maintain systems for: Offices and coworking spaces Schools and universities Data centres and IT facilities Retail stores and restaurants Healthcare and dental clinics Each environment has unique requirements, but the principle is the same: prevention is far cheaper than repair . 6. Stay Compliant and Safe Commercial air conditioning systems in the UK must comply with several regulations — including F-Gas certification , refrigerant handling rules, and periodic leak checks. By partnering with a certified London air conditioning company like INS Air Conditioning , you ensure your business stays compliant with UK environmental and safety standards. Regular servicing also includes: Checking for refrigerant leaks Verifying correct pressure and electrical connections Confirming filters and coils are clean and efficient This not only reduces risk but also ensures your system runs legally and responsibly. 7. Predictable Costs and Peace of Mind With an ongoing maintenance plan, you’ll know exactly what you’re spending — and when. Instead of surprise breakdowns or emergency call-out fees, you’ll have predictable, manageable servicing costs. At INS Air Conditioning , we offer flexible commercial maintenance contracts tailored to London businesses. You can choose from: Pay-as-you-go servicing – great for smaller offices or retail units. Annual maintenance plans – ideal for multi-unit systems or larger sites. Each plan includes priority booking, performance checks, and detailed service reports — giving you complete peace of mind. 8. The Cost of Not Maintaining Your System Let’s put the numbers in perspective. A new commercial air conditioning system can cost anywhere from £3,000 to £20,000+ , depending on size and complexity. A professional maintenance visit, by contrast, is typically a few hundred pounds. When you consider the savings on energy, repairs, and equipment lifespan, regular servicing easily pays for itself many times over . Neglecting maintenance, on the other hand, can lead to: Higher monthly bills Frequent breakdowns Shortened system lifespan Lost revenue from downtime It’s not just about keeping things cool — it’s about keeping your business running efficiently. 9. Why London Businesses Trust INS Air Conditioning Based in West London , INS Air Conditioning provides professional installation, maintenance and repair services across the Greater London area. Our engineers are F-Gas certified and experienced with all major brands and system types — from single split units to large VRV/VRF commercial systems. When you choose INS, you benefit from: Reliable, scheduled maintenance visits Transparent pricing Fast response times across London Long-term support from local experts Whether you manage a single office or multiple sites, our team can help you create a maintenance plan that suits your business and budget. Final Thoughts Air conditioning maintenance might not feel like a top priority — until something goes wrong. But for London businesses, regular servicing is one of the easiest ways to save money, reduce risk, and extend the life of your equipment . A well-maintained system is more efficient, more reliable, and better for your bottom line. To find out how a tailored maintenance plan can benefit your business, get in touch with INS Air Conditioning today — and start saving before your next energy bill arrives.

Do I Need Planning Permission for Air Conditioning in London?

November 3, 2025

If you’re considering installing air conditioning in your London home or business, you’re not alone. With UK summers getting warmer, more homeowners and business owners are choosing to invest in modern, energy-efficient cooling systems. But before installation begins, one of the most common questions we hear is: “Do I need planning permission for air conditioning?” The short answer is: not always — but in some cases, you do. The rules can vary depending on your property type, location, and the kind of system being installed. In this guide, we’ll explain everything you need to know about air conditioning planning permission in London, including when you need it, how to apply, and how to avoid costly mistakes. 1. When You Don’t Need Planning Permission The good news is that most standard residential air conditioning installations in London do not require planning permission. If your home isn’t listed and isn’t located in a conservation area, your air conditioning unit is likely covered under “permitted development rights.” That means you can go ahead with your installation as long as the following conditions are met: The external condenser unit is not installed on a wall facing a public highway. The unit is less than one metre in size (which includes most modern residential systems). It’s placed at least one metre away from your property boundary. You’re only installing one outdoor unit. If your property meets these conditions, you can usually install air conditioning without needing formal planning approval. 2. When Planning Permission Is Required There are situations where you will need to apply for planning permission before installing your air conditioning system. You’ll likely need approval if: You live in a listed building. Your property is in a conservation area or World Heritage Site. The outdoor unit will be visible from a public road or pavement. You plan to install more than one outdoor unit. Your system will generate noise that could disturb neighbours. In these cases, your local council may request a planning application to ensure your installation doesn’t affect the building’s appearance or surrounding environment. Tip: London boroughs sometimes interpret these rules differently. It’s always smart to check with your local planning authority before installation begins. 3. Flats and Apartments: The Special Rules If you live in a flat or apartment, the rules can be stricter. Even if you own the property, the exterior walls and roof are often part of the shared structure — which means you’ll need freeholder or management company approval. Some London councils also treat air conditioning units on apartment exteriors as an alteration to the building’s façade, meaning you’ll probably need planning permission. Before installation, make sure you: Get written consent from your landlord, freeholder, or managing agent. Review your lease or building agreement for restrictions. Speak to your local planning office to confirm whether permission is required. 4. Noise Regulations and Neighbour Considerations Even if you don’t need planning permission, your air conditioning system must comply with noise control regulations. Modern systems are far quieter than older models — most outdoor condensers now produce around 40–50 dB, which is quieter than normal conversation. Still, placement is key: Install the outdoor unit away from neighbouring windows or gardens. Avoid mounting it directly onto shared walls. Choose a low-noise or “night mode” model if you live in a densely populated area. At INS Air Conditioning, our engineers always carry out a full site survey to find the quietest, most practical location for your system. 5. Planning Permission for Commercial Properties For London businesses, the need for planning permission depends on your building type and how visible the external units are. You’ll typically need permission if your building is listed, sits in a conservation area, or if the outdoor units are visible from public areas. Larger commercial systems with multiple external condensers may also require approval. However, most modern offices, retail spaces, and restaurants can install air conditioning without planning permission, as long as the system falls under permitted development. If your business leases its premises, always check your lease terms — most landlords require written consent for any external installations. 6. How to Apply for Planning Permission If your property does require planning permission, the process is straightforward and usually takes 8–10 weeks. Here’s how it works: Contact your local planning authority through your borough’s website. Submit a planning application online via the Planning Portal. Include technical drawings showing where the outdoor unit will be placed. Provide manufacturer details and noise level data (we can help with this). Wait for the council to review and approve your application. At INS Air Conditioning, we support clients through this process — supplying all the technical information required for smooth approval. 7. The Benefits of Professional Guidance Planning regulations can be confusing, but that’s where expert guidance helps. At INS Air Conditioning, we: Conduct detailed site surveys before installation. Advise on whether planning permission is required. Recommend the most discreet, compliant placement for outdoor units. Provide all the technical documentation needed for your council application. Our F-Gas-certified engineers ensure every system is installed safely, legally, and to the highest standard of efficiency — saving you time and potential fines. 8. Quick Summary: Common Scenarios To recap, here’s how the rules generally apply in different London property types: Standard London homes: Usually don’t need planning permission if the system meets permitted development rules. Flats and apartments: Often do require permission and freeholder approval. Listed buildings: Always need planning permission due to historical status. Conservation areas: Often require permission, especially for visible outdoor units. Commercial properties: Sometimes need permission depending on location, visibility, and unit size. If in doubt, always check before installation — it’s much easier to get approval beforehand than to resolve issues afterward. Final Thoughts While planning permission for air conditioning in London might sound complicated, most homeowners and business owners won’t need it. The key is to check early, plan carefully, and work with a qualified installer who understands local rules. At INS Air Conditioning, we handle everything from initial consultation and planning guidance to full installation and aftercare. Whether you’re in a flat, townhouse, or commercial space, we’ll make sure your new system is compliant, efficient, and perfectly suited to your property.

Modern air conditioning systems that double as air-to-air heat pumps are among the most efficient ways to heat your home.

Cleaner heating – no fossil fuels or emissions inside your home. Dual functionality – enjoy cooling in summer and heating in winter. Eco-friendly operation – using low-impact refrigerants like R32.

How to Maximise Efficiency This Winter To get the most from your air conditioning system during colder months: Clean or replace filters every few months for smooth airflow. Keep the outdoor unit free from leaves and debris. Schedule a professional service before peak winter use. Use the timer or smart app to pre-warm rooms instead of running continuously. At INS Air Conditioning , we offer affordable maintenance and servicing plans that keep your system running efficiently, whatever the season.

Why Autumn Is the Perfect Time to Service Your Air Conditioning in London

October 2, 2025

Why this quieter season is actually the best time of year to have your AC system professionally serviced. When the summer heat fades and autumn arrives, most homeowners and businesses stop thinking about their air conditioning. But this quieter season is actually the best time of year to have your AC system professionally serviced. Whether you rely on your unit purely for cooling or you use a heat pump system to heat your property in the colder months, autumn servicing can help you: Avoid unexpected breakdowns later in the year Keep running costs low Extend the life of your air conditioning system Plan ahead before the busy summer rush returns If you live or work in London, now is the ideal time to give your system the care it needs. Avoid the Summer Rush Summer in the UK can catch people off guard, and when the first heatwave hits, demand for air conditioning services skyrockets. Engineers become fully booked for emergency call-outs, breakdowns, and new installations. Waiting until next summer to book a routine service can mean: Long waiting times for appointments Higher emergency call-out fees The stress of trying to fix your system when you need it most By booking in autumn, you’ll enjoy: Faster booking times: Engineers’ schedules are less busy. Flexible appointments: You can pick a date and time that suits you. More thorough attention: Technicians aren’t rushing to fit in last-minute emergency jobs. Essentially, autumn is the calm before the storm — perfect for proactive maintenance. Prevent Costly Winter Breakdowns If your air conditioner doubles as a heat pump (many modern systems do), it’s about to switch roles — from cooling to heating. Servicing now ensures it’s ready for that transition. A neglected system can: Struggle to produce warm air efficiently Break down on cold days when you rely on it most Require urgent, expensive repairs Even if you don’t plan to use your AC for heating, servicing before the long winter shutdown is still smart. Your engineer will check for issues like leaks, blocked drainage, or electrical problems, helping your system start up smoothly when summer returns. Improve Energy Efficiency Before the Cold Hits Energy bills are a hot topic in the UK, and an inefficient air conditioning system can quietly drive them up. Dust, blocked filters, and low refrigerant levels all force your AC to work harder, using more power. A professional service can: Clean internal components for smoother airflow Check refrigerant levels to maintain optimum performance Inspect electrical connections for safe, efficient operation Ensure your thermostat and controls are working correctly This means lower running costs whether you’re cooling in summer or heating in winter. It’s a simple step that can pay for itself in energy savings. Extend the Lifespan of Your System Air conditioning is an investment — and like any major appliance, it lasts longer when it’s looked after. Annual servicing in autumn helps to: Catch minor issues before they turn into major breakdowns Keep parts running smoothly, reducing wear and tear Protect your manufacturer warranty (many require annual servicing) With proper care, a good system can last 15–20 years or more. Skipping maintenance can dramatically shorten that lifespan and lead to expensive replacements sooner than necessary. What Our Professional Service Includes At INS Air Conditioning, we offer a thorough, manufacturer-approved service designed to keep your system reliable and efficient. Our typical autumn maintenance visit includes: Full inspection of indoor and outdoor units Cleaning or replacing air filters Checking refrigerant levels and topping up if needed Inspecting electrical connections and safety controls Cleaning evaporator and condenser coils for better airflow Testing system performance in both heating and cooling modes Checking drainage and condensate pumps This isn’t just a quick clean — it’s a full health check for your system. Perfect Timing for Upgrades or Repairs Another advantage of servicing in autumn is time to plan. If your engineer spots a developing fault or your system is ageing and inefficient, you have the whole off-season to: Compare replacement systems Take advantage of off-season installation discounts Schedule work at a time that won’t disrupt your summer comfort Replacing or upgrading in winter also avoids the supply chain pressures and longer lead times that can happen in summer. Ideal for Both Homes and Businesses INS Air Conditioning services residential properties, offices, retail spaces, and commercial buildings across London. The autumn servicing approach is valuable for everyone: Homeowners: Keep bedrooms, lounges, and home offices comfortable and energy efficient. Landlords & property managers: Ensure systems in rental properties are safe and reliable. Business owners: Avoid staff discomfort, lost productivity, and costly downtime if your AC fails mid-winter. No matter your property type, an autumn service helps protect your investment.
