How we handle air source heat pumps in Harefield
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler doesn’t qualify. If you’re dealing with questions about listed buildings or conservation areas and no space for a hot water cylinder, we can sort it out.
If your home near Harefield has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less and must meet MCS 020(a) and not be used solely for cooling. It can’t be within the curtilage of a listed building.
Air-to-water heat pumps
An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It takes over from the boiler, and is MCS certified when we install it.
For landlords and property managers
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
Looking after it afterwards
After the visit, a few habits help:
- Find out the grant position at the survey
- Keep the MCS certificate with the manufacturer’s paperwork
- Avoid switching the heat pump on and off often
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
Heat pumps in Harefield: local notes
The coast is only about 3 miles from Harefield. Coastal sites are worth mentioning at the survey, as salt air affects the outdoor unit and its fixings. The Valuation Office Agency’s council tax figures date about 51% of homes in and around Harefield 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.
Period properties close to Church of St James can suit a heat pump, though insulation and any heritage protection are checked first. Historic houses such as South Stoneham House, about 1.9 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.

- 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.
Before we arrive

Advice
Your questions about air source heat pumps in Harefield
Does sea air affect air conditioning in Harefield?
It can, as Harefield is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Is Harefield within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is there a Boiler Upgrade Scheme grant for air-to-air?
Only in limited cases, with a grant of £2,500. The system must replace the existing fossil-fuel heating, meet the home’s full heating demand, be installed by an MCS certified installer and be in a home.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for breakdowns that cannot wait. Ring 07833 053749 any time and explain the problem.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
What a customer said
“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.”
