How we handle air source heat pumps in Leatherhead
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. The work covers radiator systems, air-to-air heat pumps and air-to-water heat pumps, and people most often call us about choosing between air-to-water and air-to-air and replacing a combi boiler with a heat pump.
Plenty of older homes in Leatherhead can run on a heat pump, sometimes with larger radiators or more insulation. The heat loss calculation shows what’s needed.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What we’re called out for in Leatherhead
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
Customers usually contact us after spotting one of these:
- Moving away from fossil-fuel heating
- Working out whether radiators need upsizing
- Finding a place for the outdoor unit
If your home is listed, like Polesden Lacey about 3.4 miles south-west, listed building consent comes before any heat pump work.

Leatherhead: your questions answered
Can I fit a heat pump in Leatherhead without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Leatherhead is a short walk from the Leatherhead Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Mole Valley council, usually the authority for Leatherhead.
Does the Boiler Upgrade Scheme cover homes in Leatherhead?
Yes, the scheme covers homes in England, including Leatherhead, 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. We hold MCS certification, so the application is ours to make for you.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Who is responsible for leak checks?
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’ll work out which band applies to yours.
How long does a heat pump installation take?
Expect it to take a few days for most air-to-water installations, with air-to-air systems often quicker. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.

What owners can safely do
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
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. Opening up the units, the electrics and the refrigerant circuit are a job for us.
