Heat load surveys and system design in Havant
Hot spells reach the South East early, which makes spring the easiest time to arrange an installation. No two rooms in Havant gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Havant, a standalone design pack can go straight to your builder. Havant is about 19 miles from Southampton and falls within our Hampshire coverage. That includes the PO9 postcode district.
Prices in Havant
Heat load surveys and system design in Havant 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. As an example, the Design pack option (drawings and schedules for one home) would typically be £495–£945 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.
The survey
A survey in Havant usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. Surveys in Havant cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
