Heat load surveys and system design in Oxford
For self-builds and extensions in Oxford, a standalone design pack can go straight to your builder. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
No two rooms in Oxford gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Oxford is one of the main towns we cover in Oxfordshire, alongside Banbury and Abingdon. Homes in OX1 are all within our coverage.
Prices in Oxford
Heat load surveys and system design in Oxford typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. South East England is one of the dearer parts of the UK for trades, which shows in the range. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. For reference, the Design pack option in Oxford (drawings and schedules for one home) usually comes to about £495–£945.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. A survey in Oxford usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
