Heat load surveys and system design across East Sussex
Every Brighton quote starts with a room-by-room survey rather than a guess from floor area. No two rooms in Brighton gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. The South East sees some of the UK's warmest summer days, and south-facing rooms and conservatories feel it first.
Prices in East Sussex
Heat load surveys and system design in East Sussex typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. 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
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
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. A survey in East Sussex 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.
