Air source heat pumps in Hillingdon
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Sizing by rule of thumb isn’t good enough. We are often asked to deal with working out where a cylinder could go and ageing boilers that will need replacing, across underfloor heating, hot water cylinders and air-to-water heat pumps.
Terraced houses in a London area like Hillingdon can suit a heat pump well, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Common questions in Hillingdon
Can I get the Boiler Upgrade Scheme grant in Hillingdon?
Hillingdon is in England, where the Boiler Upgrade Scheme runs. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
Can I fit a heat pump in Hillingdon without planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 8 listed entries sit within 0.5 miles of central Hillingdon. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Hillingdon council, which is usually the planning authority for Hillingdon first.
How long does a heat pump installation take?
It takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How much does an air source heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.

How the visit works
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A few pictures of the room, the outside wall and the fuse board help us plan a job in Hillingdon.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Let us know where the consumer unit is
- Clear a path to the units and the space around them
- Mention any parking restrictions near the property

What a heat pump looks like in Hillingdon
About 50% of homes in and around Hillingdon were built between the wars, according to Valuation Office Agency council tax records. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. In London, outside space and the rules for flats often decide which kind of heat pump suits.
With Ickenham Hall about 1.8 miles north, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near Church of St John, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Looking after your system
Here’s the after-treatment advice, short and simple:
- Clear leaves and debris from the outdoor unit
- Keep the MCS certificate with the manufacturer’s paperwork
- Know the servicing conditions in your warranty
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
What happens if it’s left?
Permitted development rules can change, and conditions vary between properties. We look at the planning position early, so there are no surprises covering listed buildings, conservation areas and any Article 4 direction. Planning ahead in Hillingdon means you choose the date, not the weather.
Height, access and the distance between the indoor and outdoor units can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
