Heat load surveys and system design in Feltham

London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. Every Feltham quote starts with a room-by-room survey rather than a guess from floor area.

No two rooms in Feltham gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our London coverage takes in Feltham, about 13 miles from central London. Postcode districts we cover here include TW13.

Prices in Feltham

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. 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 Feltham (drawings and schedules for one home) usually comes to about £495–£1,045.

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

A survey in Feltham 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. On a survey in Feltham 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.
