Heat load surveys and system design in Epsom
No two rooms in Epsom gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
For self-builds and extensions in Epsom, a standalone design pack can go straight to your builder. Epsom sits around 12 miles from Woking, inside our Surrey area. Postcode districts we cover here include KT17 and KT19.
Prices in Epsom
Heat load surveys and system design in Epsom typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. Typical Design pack work (drawings and schedules for one home) lands around £495–£945 in this area.

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 Epsom 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. We book surveys in Epsom at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
