Heat load surveys and system design in South Ockendon
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. Every South Ockendon quote starts with a room-by-room survey rather than a guess from floor area.
For self-builds and extensions in South Ockendon, a standalone design pack can go straight to your builder. South Ockendon is about 19 miles from Southend-on-Sea and falls within our Essex coverage. That includes the RM15 postcode district.
Prices in South Ockendon
Guide prices around South Ockendon run from £445 to £1,395 for a standalone design pack including VAT. That is above the UK middle, mainly because labour and access cost more in the East of England. 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 £445–£895 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.
