About building control


National building standards apply to most buildings and extensions.

Our highly experienced team of professional surveyors is on hand to help you with your building project, no matter how big or small.

Submit an application

If you'd like to apply for building control approval, you can submit an application through the Planning Portal.

If you have problems or questions, we recommend using the Planning Portal online help centre, or you can call them on 0333 323 4589.

Our fee calculator can help you find the right application fee.

If you don’t use the Planning Portal you can download and complete an application form from our Building Control website.
