Air source heat pumps in Westerham
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to 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 radiator systems, homes heated by oil, LPG or gas and air-to-water heat pumps, and the jobs we see most are a boiler that’s getting old and wanting to stop using oil, LPG or gas for heating.
In a London area like Westerham, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and typically a cylinder, while an air-to-air system needs less space.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Fixed-price quotes for air source heat pumps in Westerham
A fixed price needs a few facts first. We check:
- The pipe route between the units
- The electrical supply and whether a new circuit is needed
- How many units are involved
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before we start, so you know where you stand.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Your installation or service records
- The postcode and whether it’s a home, flat or business
- A close-up of the unit’s label showing the model number

What we’re called out for in Westerham
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
Any of these is worth a proper look:
- Working out where a cylinder could go
- Deciding which kind of heat pump suits the home
- Not knowing whether a grant applies
With Quebec House about 0.2 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump.
Questions to ask before booking
- How extra work would be agreed if they find something unexpected
- What records you get at the end
- What’s in the price and what is not
Safe owner checks
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Before a visit in Westerham, we ask where the van can stop and how we reach the outdoor unit.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
- Keep pets and children away from the work area
Ask for a quote
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone us on 07833 053749 or fill in the contact form.

FAQs for Westerham
Can I fit a heat pump in Westerham without planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Westerham is in a conservation area. 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 local planning authority (for Westerham, usually Sevenoaks council).
Does the Boiler Upgrade Scheme cover homes in Westerham?
Westerham is covered, as the scheme runs across England and Wales. 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.
Which type of heat pump is right for my home?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
How long does a heat pump installation take?
It takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Which brands do you work with?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Will my radiators work with a heat pump?
It varies from room to room. We check them all during the survey and the quote shows what’s needed.

Air source heat pumps in Westerham: the local picture
Valuation Office Agency council tax records put about 40% of homes in the Westerham area before 1919, and the last census (2021) found about 64% of households in detached or semi-detached houses. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Houses typically have space for an outdoor unit and a hot water cylinder. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Older homes near Church of St Mary the Virgin may need extra checks for planning and heat loss before a heat pump is designed.
