Heat load surveys and system design in Crawley
Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus. Every Crawley quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Crawley gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Crawley and the rest of West Sussex, including Worthing and Bognor Regis. That includes the RH11 and RH77 postcode districts.
Prices in Crawley
Heat load surveys and system design in Crawley typically come in at £495–£1,495 for a standalone design pack including VAT, based on South East England rates. South East England is one of the dearer parts of the UK for trades, which shows in the range. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. For reference, the Design pack option in Crawley (drawings and schedules for one home) usually comes to about £495–£945.
