Heat load surveys and system design in New Milton
No two rooms in New Milton gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. 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 New Milton quote starts with a room-by-room survey rather than a guess from floor area. New Milton is about 15 miles from Southampton and falls within our Hampshire coverage. We cover BH25 and the streets around them.
Prices in New Milton
Heat load surveys and system design in New Milton typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. That is above the UK middle, mainly because labour and access cost more in South East England. 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 New Milton (drawings and schedules for one home) usually comes to about £495–£945.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in New Milton 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. 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.
