What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
About our air source heat pumps in Hook
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. We’re often asked to deal with questions about listed buildings or conservation areas and finding a place for the outdoor unit, on air-to-air heat pumps, air-to-water heat pumps and radiator systems.
For flats in Hook, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Rented and managed buildings
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
Facilities teams in offices, schools and public buildings book us too across Greater London. Work can be phased by floor, zone or building around the people who use them.
Looking after your system
Looking after it is simple, and it makes the next visit easier:
- Seal draughts where you can
- Keep the MCS certificate with the manufacturer’s paperwork
- Check eligibility for the Boiler Upgrade Scheme early
Should you have questions after the install, give us a ring on 07833 053749 or use the quote form and we’ll talk it through. A yearly service is a good habit.
Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.
Common questions in Hook
Does the Boiler Upgrade Scheme cover homes in Hook?
Yes, the scheme covers homes in England, including Hook, if they qualify. 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 isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Can you fit air conditioning in a London flat in Hook?
Often, yes, but the lease and the freeholder usually have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Do you look at the job first?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.
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 prices are set after a survey, and we confirm the VAT on the quote.
How much time does a heat pump install need?
Expect it to take from a couple of days to around a week, depending on the system and how much of the heating changes. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a job in Hook, tell us about parking, permits and access to the building when you get in touch.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Clear the space around the indoor unit, or where it will go
- Unlock any gate, garage or side passage we need

Homes in Hook and heat pumps
About 43% of homes in Hook and the neighbourhoods around it were built between the wars, according to the Valuation Office Agency’s council tax figures. 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.
Homeowners near Chessington North station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. Period properties close to St Paul's can suit a heat pump, though insulation and any heritage protection are checked first.
