Heat load surveys and system design in Sudbury
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. For self-builds and extensions in Sudbury, a standalone design pack can go straight to your builder.
Every Sudbury quote starts with a room-by-room survey rather than a guess from floor area. Our Suffolk coverage takes in Sudbury, about 18 miles from Ipswich. Homes in CO10 are all within our coverage.
Prices in Sudbury

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 Sudbury 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
