Heat load surveys and system design in Stevenage
For self-builds and extensions in Stevenage, a standalone design pack can go straight to your builder. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
No two rooms in Stevenage gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Stevenage lies roughly 19 miles from Watford, and we cover it as part of Hertfordshire. Coverage includes SG1.

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 Stevenage 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. Surveys in Stevenage cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
