Heat load surveys and system design in Bicester
For self-builds and extensions in Bicester, a standalone design pack can go straight to your builder. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Every Bicester quote starts with a room-by-room survey rather than a guess from floor area. Bicester sits around 11 miles from Oxford, inside our Oxfordshire area. We cover OX6, OX25, OX26 and OX27 and the streets around them.

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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. 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.
