Great Holcombe: your questions answered
Will you come out to Great Holcombe?
Yes. Great Holcombe is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Does the Boiler Upgrade Scheme cover homes in Great Holcombe?
Great Holcombe is in England, where the Boiler Upgrade Scheme runs. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
How much does an air source heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Should I choose air-to-water or air-to-air?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air doesn’t heat hot water, and we explain which suits your home.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Air source heat pumps in Great Holcombe
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. 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. Common call-outs are for questions about listed buildings or conservation areas and deciding on the outdoor unit position, on underfloor heating, hot water cylinders and homes heated by oil, LPG or gas.
Homes around Great Holcombe typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and call us on 07833 053749, or email if that’s easier.

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.

Pictures of the space and where the outdoor unit could go let us plan the work in Great Holcombe.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- We install, commission and register the system under MCS.
Before we arrive

The Boiler Upgrade Scheme
Eligibility depends on the property and the scheme rules and we confirm it before anything is agreed.
Radiators and underfloor heating
Underfloor heating suits a heat pump’s lower flow temperature and we look at it during the survey.
When it’s something else
Some problems need a different service or another trade:
- Promising eligibility for the Boiler Upgrade Scheme
- Getting planning permission or listed building consent on your behalf
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If in doubt, call us on 07833 053749 and we’ll say what we think.

Homes in Great Holcombe and heat pumps
Church of St Giles, listed at grade I, is one of roughly 13 protected buildings and structures in the half-mile around Great Holcombe’s centre. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? VOA council tax data date about 40% of homes in the Great Holcombe area to the post-war years, 1945 to 1972, and the 2021 Census found about 85% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Historic houses such as Garsington Manor, about 3.8 miles north-west, are a reminder that listed homes need consent before a heat pump goes in. Older homes near Church of St Giles may need extra checks for planning and heat loss before a heat pump is designed.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
