Prices in Wallingford

Guide prices around Wallingford run from £1,745 to £3,845 per system including VAT. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Wallingford up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our South East England figures, the Popular option (3.5 kW unit with Wi-Fi to warm up before you walk down the garden) is about £2,195–£2,995.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.

Planning and permissions

Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

The survey

We book surveys in Wallingford at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. On a survey in Wallingford the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
