Heat load surveys and system design in Witney
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. Every Witney quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Witney gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Witney as part of Oxfordshire, roughly 10 miles from Oxford. We cover OX8, OX28 and OX29 and the streets around them.
Prices in Witney
In South East England, our guide range for heat load surveys and system design is £495–£1,495 for a standalone design pack, including VAT. South East England is one of the dearer parts of the UK for trades, which shows in the range. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. As an example, the Design pack option (drawings and schedules for one home) would typically be £495–£945 here.

Planning and permissions
For most houses in Witney, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
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.
