Air source heat pumps
The standard choice for most homes in Sevenoaks. An outdoor unit takes heat from the air and feeds your radiators, underfloor heating and hot water.
Air sourceMCS-certified air source and ground source heat pump installation for homes and businesses in Sevenoaks. Free heat loss survey, fixed quote and the grant deducted from your invoice.
We work regularly in Sevenoaks, so we know the property stock: large detached and period property with the land for ground source, and a lot of listed stock in the town centre. That shortens the survey and means the outdoor unit ends up somewhere that works both technically and visually.
Sevenoaks is largely off the mains gas grid, and a lot of properties here run on oil. That makes the heat pump case unusually strong: the running cost saving against oil is immediate rather than marginal, and you lose the tank, the deliveries and the exposure to price spikes. It also means the grant is worth more to you. Off-gas-grid homes replacing heating oil can claim £9,000 instead of £7,500 on installations between 21 July 2026 and 31 March 2027.
Every job starts with a room-by-room heat loss survey, free and with no obligation. If a heat pump is not right for your property, we will tell you at that stage rather than after you have paid for one.

ProcessAn air source system typically costs £9,000 to £14,000 before grant, and more on large or period property. After the £7,500 Boiler Upgrade Scheme grant most households in Sevenoaks pay between £1,500 and £6,500.
Yes. Sevenoaks is within our normal working radius from Tunbridge Wells, so we survey, install, service and attend breakdowns there as standard.
Some of them, usually four to six in a typical three-bed. Heat pumps run at a lower flow temperature than boilers, so radiators need to be larger to emit the same heat. The room-by-room heat loss survey tells us exactly which.
Most domestic air source installations in Sevenoaks are permitted development, and the rules were relaxed in May 2025. The MCS 020(a) noise assessment still has to pass. Listed buildings always need consent and conservation areas need checking, which we do before designing the unit position.
