Building Control

The Council of the Isles of Scilly has formally delegated the Building Control Function to Cornwall Council, who has operated this service on behalf of the Council of the Isles of Scilly for many years, so customers should not experience or notice any change as a result.

All enquiries and Building Control applications should be made direct to Cornwall Council, via the following link Cornwall Council .This link also contains comprehensive information to assist you with all of your Building Control needs.

DANGEROUS STRUCTURES:  Building Control has a responsibility to deal with dangerous buildings as they occur. Buildings may become gradually dangerous due to old age, deterioration or settlement, or by more dramatic causes such as storm, explosion, fire or impact by vehicles. All buildings which appear to be dangerous or unsafe should be reported as soon as possible to Building Control by calling 01872 224792 (24 hours). We will treat the matter with the utmost urgency More information can be found here.

With all building work, the owner of the property is responsible for meeting the relevant Planning and Building Regulations. Building Regulations apply to most building work so it is important to find out if you need permission. Further information can be found at Cornwall Council

Your Building Control Officer, Annette Buckingham is not based on the islands but visits on average every two weeks. Please contact us via the above details if you wish to request a site visit or if you need to get in touch to discuss a proposed project or any work in progress.

Non-Mains Drainage

There are a very limited number of public drainage systems to connect to on the Isles of Scilly meaning that private drainage arrangements such as septic tanks are often necessary. In addition to Building regulations requirements under Part H, guidance on the disposal of sewage where no mains drainage is available under The Environmental Permitting (England and Wales) (Amendment) (England) Regulations 2014 can be found here and there is a leaflet on small sewerage treatment systems.
