Building regulation applications

Search building control applications >>

Most building work, whether new, alterations, extensions or change of use, requires building regulations approval. You can make one of two types of application - full plans or building notice. For further information see the Planning Portal.

Full plans application

Extending, altering or building a non-domestic building usually needs a full plans application. You need to send us detailed plans, specifications and structural calculations. We’ll issue an approval notice if the plans meet regulations, or contact you if plans need amendments or must be rejected.

If the work is carried out in line with the approved plans, it will meet the regulations, and you can give the approval notice to mortgage lenders solicitors, and surveyors.

You can make a full plans application online or download a full plans application form (PDF 153.4KB) .

Building notice

Building notice approval allows building work to be carried out without detailed plans. It is used when the work is straight forward, and the builder knows the regulations well.

We inspect the work as it proceeds, and may request further information such as structural design calculations, construction details and specifications of materials. You can save time and money by not having to prepare and submit detailed plans, but if the completed work does not meet regulations, there may be a delay and extra costs to correct it.
