Your questions about air source heat pumps in Harefield
Do you cover smaller places like Harefield?
Yes. Harefield is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit a heat pump in Harefield without planning permission?
That depends on the building and where the outdoor unit goes. The Harefield Village Conservation Area takes in the middle of Harefield. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Hillingdon council, typically the authority for Harefield.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. With air-to-air, hot water needs another source and the survey helps decide.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
Will my home qualify for the Boiler Upgrade Scheme?
We confirm eligibility at the survey stage. There’s one grant per property, you can’t get one to replace a low-carbon system, and hybrids are excluded and other conditions apply.
Air source heat pumps in Harefield
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. We are often asked to deal with deciding which kind of heat pump suits the home and deciding on the outdoor unit position, on underfloor heating, radiator systems and hot water cylinders.
Older homes around Harefield can be draughty or have solid walls, which a heat loss calculation will show. Sometimes insulating first makes more sense.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

System by system
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
Hot water cylinders
Cylinder size is based on your household’s needs.
Let and managed properties
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Heat pumps in Harefield: local notes
VOA council tax data date about 42% of homes in the Harefield area to the post-war years, 1945 to 1972. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.
Ickenham Hall, roughly 3.4 miles south-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. Period properties close to Harefield Baptist Church can suit a heat pump, though insulation and any heritage protection are checked first.

How the visit works
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Visits to a place like Harefield are planned ahead, so we arrive with what the job needs.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We explain which type of heat pump suits the home and whether a grant could apply.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Move furniture away from the wall where we will be working
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Find the manual or the paperwork for the system, if you have it
