Heat load surveys and system design in Pembroke Dock
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. No two rooms in Pembroke Dock gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Pembroke Dock, a standalone design pack can go straight to your builder. We cover Pembroke Dock as part of Dyfed, roughly 29 miles from Carmarthen. That includes the SA72 postcode district.
Prices in Pembroke Dock
Budget around £365–£1,145 for a standalone design pack including VAT for heat load surveys and system design in and around Pembroke Dock. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. 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 £365–£745 here.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Pembroke Dock can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
We book surveys in Pembroke Dock at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Pembroke Dock 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.
