Apply for building control

Application Types

There are three different application types:

• Full plans – The plans, specifications and other supporting documents are provided for ‘approval’, where a Registered Building Inspector reviews them for compliance, identifying any areas of non-compliance. As compliance is checked prior to works commencing the risk of issues on site is reduced.
• Building notice – Is for smaller, less complex works such as small (<10m2) extensions, internal alternations, or window replacements. The works are assessed on site however information, such as structural calculations may still be required. Building Notices cannot be used for certain works such as works over sewers and commercial works. 
• Regularisation – Where works have started or been completed without the required approvals this application type should be used. As much information should be provided as possible, any additional information required will be quoted for.

Application Forms

Applications should be made using the following application forms until further notice. These can either printed and posted to the address on the form or completed digitally and emailed to [email protected].
