Air source heat pumps in Harrow Weald
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you will need another way to do that. The work covers air-to-water heat pumps, hot water cylinders and homes heated by oil, LPG or gas, and people most often call us about choosing between air-to-water and air-to-air and checking emitters for a heat pump.
For flats in Harrow Weald, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, so we check the position before we design.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Why deal with it now?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. Doing the survey properly from the start avoids that. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. We give you a fixed price before we start, so you know where you stand.

Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it, and we apply for it as the installer.
Radiators and underfloor heating
Underfloor heating works well with heat pumps because it uses lower temperatures and we look at it during the survey.
Honest limits
Not every problem is solved by air source heat pumps, and we’d rather say so up front. It does not solve:
- 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
- Grants for hybrid systems or replacements of low-carbon systems
If you’re not sure, just call us on 07833 053749 or send an email and we will give you a straight answer before you book.

Heat pumps in Harrow Weald: local notes
About 49% of homes in and around Harrow Weald were built between the wars, according to the Valuation Office Agency’s council tax figures. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is near Headstone Lane station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Headstone Manor, roughly 0.9 miles south-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

Questions from Harrow Weald
Can I have air conditioning in a flat in Harrow Weald?
Typically, yes, though leaseholders normally need the freeholder’s agreement. 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.
Is the heat pump grant available in Harrow Weald?
Yes, if the home and the heat pump meet the scheme’s rules: Harrow Weald is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Will my radiators work with a heat pump?
It varies from room to room. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Before a visit in Harrow Weald, we ask where the van can stop and how we reach the outdoor unit.
- We find out about your home and the heating you have now.
- 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.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Unlock any gate, garage or side passage we need
- Dig out any previous service or F-Gas records
- Tell us about access, such as roof hatches, high walls or locked plant areas
