Heat load surveys and system design in Welling
Every Welling quote starts with a room-by-room survey rather than a guess from floor area. Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell.
For self-builds and extensions in Welling, a standalone design pack can go straight to your builder. Our London coverage takes in Welling, about 10 miles from central London. We cover DA16 and the streets around them.
Prices in Welling
Our London guide price for heat load surveys and system design is £495–£1,645 for a standalone design pack, VAT included. That is above the UK middle, mainly because labour and access cost more in London. 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. Typical Design pack work (drawings and schedules for one home) lands around £495–£1,045 in this area.

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
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. On a survey in Welling 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.
