Change of use
If you're planning to change how a building is used, you may need Building Regulations approval. This is to make sure the building meets essential health and safety standards for its new purpose—especially if it will be used by the public or for residential accommodation.
You’ll need approval for changes such as converting a building into:
- A house or flat (including changes to the number of dwellings)
- A hotel or guest house
- A care home, hospital, or other institution
- A public building, such as a school, theatre, or place of worship
- Residential rooms, such as hotel or care home accommodation
- A shop or retail space
These types of conversions often involve structural changes, fire safety measures, and accessibility improvements. For more detailed technical information, visit our technical guidance pages.
