Check if work needs building regulations approval

Check whether your building work needs building regulations approval and find out which application you need to make.

The checker will tell you:

• if your work needs approval
• if your work may be exempt
• which type of application you need to make

You will need:

• the property's postcode
• the floor area of any new building, extension or structure in square metres

You may also need information about the work you are planning.

Some types of building work may not need building regulations approval.

This can include:

• conservatories
• porches
• carports and covered yards
• small detached buildings that do not contain sleeping accommodation
• some extensions and similar structures

Use the checker to find out whether your work is exempt.

View our guidance on extensions for advice on:

• finding professional advice and support
• preparing a design brief
• the different types of building regulations applications

Read guidance from Local Authority Building Control (LABC) website. It has guidance from many local authorities about:

• planning home improvement projects
• understanding building regulations
• the types of work that need approval
• making sure work meets building regulations requirements
