Will my smaller home improvements need building regulations approval?
Some types of minor building or improvement works like putting up sheds, car ports or porches do not need building regulations consent.
The general rule is that if they are small (less than 30m2), are built of non-combustible material, are separated from nearby buildings or land and do not contain sleeping accommodation, they are exempt. However it is always best to check with your local council building control team before starting work.
Other kinds of minor improvements - such as installing central heating can be carried out by ‘competent persons’. Visit the competent persons’ website.
