Air source heat pumps in Cotman's Ash
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, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. We are often asked to deal with moving away from fossil-fuel heating and choosing between air-to-water and air-to-air, across air-to-air heat pumps, air-to-water heat pumps and homes heated by oil, LPG or gas.
Older and listed homes in villages like Cotman's Ash need extra care, and permitted development does not cover listed buildings, so we check consent first.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

FAQs for Cotman's Ash
Is the heat pump grant available in Cotman's Ash?
Yes, the scheme covers homes in England, including Cotman's Ash, 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 is not an add-on to a boiler. You do not apply yourself: the MCS certified installer does, which is us.
Is Cotman's Ash within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
How much does an air source heat pump cost?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. The final price depends on the heat loss survey, the radiators and the cylinder, and you get a fixed-price quote.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Cotman's Ash and across Kent. Let us know who the records should go to.
How long does a heat pump installation take?
The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The survey lets us set a firm programme, and you can phone 07833 053749 or fill in the contact form to book it.
Can I do any of the installation myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.

Safe owner checks
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring 07833 053749 or send an email.
Air source heat pumps in Cotman's Ash: the local picture
The Valuation Office Agency’s council tax figures date about 43% of homes in the Cotman's Ash area to the post-war years, 1945 to 1972, and about 82% of households live in detached or semi-detached houses, according to Census 2021 figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. The middle of Cotman's Ash is part of a conservation area. Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Sevenoaks council) before the heat pump design is finished.
Period properties close to Church of Saint Mary the Virgin can suit a heat pump, though insulation and any heritage protection are checked first. Historic houses such as Lullingstone Castle, about 3.4 miles north-west, are a reminder that listed homes need consent before a heat pump goes in.

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. Waiting rarely makes an air conditioning problem smaller.
What you pay depends on the type of system and how many units are involved, 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.
