Application Forms


The General Data Protection Regulations require us to revise the notification we provide to our customers on our application forms as to how and for what reason we intend to use your data. To allow for this, we have temporarily removed the BCNI application forms until a suitable wording is agreed and implemented across Local Authority Building Control. If you require a Building Control Application form, please contact your local Councils Building Control Office. Contact details can be found by clicking here. It is anticipated that revised BCNI application forms will be available in the near future. We apologise for any inconvenience that this may cause.


Making an application


Building Regulations apply to most ‘building work’. This requires you to make an application before proceeding with the work. Building Control applications must be submitted to Building Control Services. Applications are required for new build, property extensions and also work of a minor nature; particularly, installing fittings, new heating appliances and systems, altering a building’s structure, changing the use of a building or building work affecting fire safety. In some instances, repair work to buildings will also require a Building Control application. Some work is exempt from Building Regulations but may require approval under other legislation, such as an application to the Planning Service. The best way to check that you are doing the right thing is to contact Building Control Services before starting your project. Getting good advice from the beginning will help you avoid problems later.
