Heat load surveys and system design in Basildon
Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure. For self-builds and extensions in Basildon, a standalone design pack can go straight to your builder.
Every Basildon quote starts with a room-by-room survey rather than a guess from floor area. Basildon lies roughly 11 miles from Southend-on-Sea, and we cover it as part of Essex. Postcode districts we cover here include SS14.
Prices in Basildon
Our East of England guide price for heat load surveys and system design is £445–£1,395 for a standalone design pack, VAT included. That is above the UK middle, mainly because labour and access cost more in the East of England. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. On our East of England figures, the Design pack option (drawings and schedules for one home) is about £445–£895.

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
On a survey in Basildon 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.
