Choose the right building regulations application

Building notices are quick and are for smaller, internal changes to your home. Full Plans applications are for more complicated building work. Find out which you'll need.

Building Notices

If you're planning small, internal changes to your home then a Building Notice could be the best option.

You can start your building work two working days after submitting your Building Notice application.

You don’t get formal approval before you start work, which you do with a Full Plans application, but we acknowledge your Building Notice.

We will issue a completion certificate when our site inspectors say the completed work complies with the building regulations.

There are specific projects when Building Notices cannot be used.

Building Notices cost less and are quick

It costs less because with a Building Notice, you may avoid getting detailed plans made. However, while your works are happening we might ask you to provide information to show your build complies with the regulations.

It's a faster process because you can submit your application just 2 working days before starting your building work, if you need to. A building control surveyor will visit you, inspect the works as they progress and inform you of other requirements.

Go to Building Notices on the Planning Portal website to find out more.

Full Plans applications

If you're making major changes or doing commercial building works, then you should do a Full Plans application.

You will probably want to submit a Full Plans application if you are carrying out works such as:

  • an extension
  • a new building
  • building work on commercial buildings
  • changing your building's use
  • building at a school

When applying for Full Plans approval, you'll need to include detailed plans of the work you're doing.

Our Building Control team will examine the plans before you start work. They will let you know if you can start work or if you need to change your plans first.

We will issue a completion certificate when our site inspectors know the completed work complies with the building regulations.

Full Plans applications are for more complicated builds

When you do a Full Plans application you have to submit detailed plans for Building Control approval. You have the security of knowing that your proposals comply with all the relevant national regulations.

With approved plans it tends to be easier communicating with builders. Without plans, sometimes your builder may not fully understand your intentions. 

Go to Full Plans applications on the Planning Portal website to find out more.

Regularisation (retrospective application)

If past building work has taken place without getting building regulations approval, the owner of the building can apply for Regularisation. 

You may need to expose, remove and/or rectify works if the build doesn't comply with the building regulations and if you want a Regularisation certificate.

If you wish to apply for Regularisation please contact our Building Control team to discuss your circumstances.
