How we handle air source heat pumps in Hillesden
A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If the problem is checking eligibility for a heat pump grant and a boiler that’s getting old, we can sort it out.
If your home in or near Hillesden is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Why deal with it now?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. Waiting rarely makes an air conditioning problem smaller.
Our prices page shows typical ranges, but your price depends on the job in front of us. For a fixed-price quote, give us a ring on 07833 053749 or email us, and we will explain what it covers.

What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Photos of the existing unit help with repairs and servicing in Hillesden.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Keep pets and children away from the work area
- Clear a path to the units and the space around them
- Let us know if the building has a permit or sign-in process

Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Advice
Before you call an engineer
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Homes in Hillesden and heat pumps
About 32% of homes in and around Hillesden have been built since 2000, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 79% of households in detached or semi-detached houses. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder. Central Hillesden is inside the Church End Conservation Area. Historic England lists about 6 buildings and structures within half a mile of the centre of Hillesden, including Church of All Saints (grade I). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with Buckinghamshire council, typically the planning authority here.
Historic houses such as Claydon House, about 3 miles south-east, are a reminder that listed homes need consent before a heat pump goes in. Period properties close to Church of All Saints can suit a heat pump, though insulation and any heritage protection are checked first.

FAQs for Hillesden
Can I get the Boiler Upgrade Scheme grant in Hillesden?
Hillesden is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. You do not apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like Hillesden?
Yes. Hillesden is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
How long does a heat pump installation take?
It takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
What does an air-to-water heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are, and air-to-air systems are priced after a survey.
