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
Surveys in East Cowes are arranged around travel. We confirm the date and any travel, ferry or accommodation cost in writing before you commit, then the survey covers rooms, pipe routes, electrics and noise as normal. 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.
