Heat load surveys and system design across the Isle of Wight
Every Newport quote starts with a room-by-room survey rather than a guess from floor area. For self-builds and extensions in Newport, a standalone design pack can go straight to your builder. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
Prices on the Isle of Wight
Guide prices around the Isle of Wight run from £495 to £1,495 for a standalone design pack including VAT. 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. Travel, ferry or accommodation costs are not in these figures; they are quoted as a fixed amount in writing before you book.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
The survey
On the Isle of Wight we often start with photos, room measurements and the make of any existing system, so the survey visit is focused and any travel cost can be quoted in writing first. Where travel is involved, we agree the survey arrangements and any travel cost up front. On the day, the engineer measures the rooms, checks the electrics and agrees the outdoor unit position with you.
