Heat load surveys and system design in New Malden
Every New Malden 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.
No two rooms in New Malden gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. New Malden lies roughly 9 miles from central London, and we cover it as part of London. That includes the KT3 postcode district.
Prices in New Malden
Heat load surveys and system design in New Malden typically come in at £495–£1,645 for a standalone design pack including VAT, based on London rates. That is above the UK middle, mainly because labour and access cost more in London. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. 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
On a survey in New Malden 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. 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.
