Air source heat pumps for homes and businesses in Kings Langley
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers hot water cylinders, radiator systems and underfloor heating, and people most often call us about an oil, LPG or gas boiler near the end of its life and not knowing whether a grant applies.
If your home near Kings Langley has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

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. For businesses, we can usually work room by room or zone by zone. The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the existing unit and its label help with repairs and servicing near Kings Langley.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- After commissioning, you get the MCS certificate and a handover.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Tell us about any building rules, permits or sign-in
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Why deal with it now?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. An early booking makes the visit to Kings Langley easier to arrange.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will go through it with you.

Safe owner checks
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.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Kings Langley questions
Is planning permission needed for a heat pump in Kings Langley?
It depends on the property. The Kings Langley Conservation Area is close to the centre of Kings Langley. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the planning department at Dacorum council, normally the authority for Kings Langley first.
Can I get the Boiler Upgrade Scheme grant in Kings Langley?
Kings Langley is in England, where the Boiler Upgrade Scheme runs. 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 is not an add-on to a boiler. The installer applies, and we are MCS certified.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Are you F-Gas certified?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What does an air-to-water heat pump cost?
£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.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Different systems, different jobs
Air-to-air heat pumps
An air-to-air system heats rooms directly and can also provide cooling. Hot water needs a separate source so you will need another way to heat it.
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small, and both cause problems.
