Do I need a building regulations application?
Building Regulations applications are needed for most construction projects:
- All new buildings except agricultural buildings
- Garages that are not fully detached and under 30 square metres
- All extensions no matter how small – watch our video about building an extension
- Some conservatories and porches (many are exempt but these must be separated from the house by doors and can’t be heated) – we also have a video about conservatories
- Roof extensions, balconies and roof terraces
- Basements and basement extensions
- All loft conversions, roof extensions, balconies and roof terraces – watch our video about loft conversions
- All garage conversion – watch our video
- Barn conversions
- Subdividing a house into flats
- Converting flats back into a house
- Creating a ‘granny annex’
- Creating a new or ensuite bathroom or cloakroom
- Installing a new kitchen
- Taking out a loadbearing wall – you need to ask a structural engineer to confirm that your wall isn’t supporting the walls, floors or roof above it
- Taking out a non-loadbearing wall if it separates a room from your hall, staircase or landing
- New installation or replacement of a heating system or any boiler, regardless of fuel type
- New installation or replacement of an oil tank
- Installation of a new bathroom if existing plumbing is altered or if new plumbing is installed

- Replacement of roof coverings on pitched and flat roofs even if this is just like for like
- Replacing your floor
Some work can be carried out without informing Building Control if you're using a registered installer from a competent persons scheme, including the following:
- Most repairs, replacements and maintenance work (except replacements of combustion appliances, oil tanks, electrical fuse boxes or glazing units which do need to be notified).
- Additional power points or lighting points or any other alterations to existing circuits (except around baths and showers)
- Like for like replacements of baths, toilets, windows, basins or sinks.
