Key Takeaways
- Building Regulations set the technical standards for safety, structure, insulation, drainage and fire, separate from planning permission.
- They apply to most building work even when planning permission is not needed.
- Common notifiable works include structural changes, electrics, new bathrooms, extensions and heating.
- A completion certificate from Building Control is essential proof when you sell.
- Sign-off can be via the local authority or an approved inspector.
Building Regulations are the technical rulebook for safe, sound building work, and they matter on almost every renovation, even when planning permission does not. Here is what they cover, when they apply, and why the completion certificate is so important.
What are Building Regulations?
Building Regulations set the minimum standards for the design and construction of building work, covering structure, fire safety, insulation, ventilation, drainage and electrical safety. They are entirely separate from planning permission: planning decides whether and how something looks, Building Regulations decide how it is built.
When do they apply?
Most building work is covered. Common notifiable works include:
- Structural changes such as removing a load-bearing wall
- Extensions and loft conversions
- Electrical rewiring and new circuits (Part P)
- New or relocated bathrooms and kitchens involving services
- New heating systems and boilers
- Replacement windows, drainage and insulation upgrades
Purely cosmetic work, such as decorating or a like-for-like kitchen in the same layout, usually does not.
How sign-off works
The work is inspected at key stages by either your local authority Building Control or a private approved inspector. They check elements before they are concealed, for example steelwork before it is encased, and on completion they issue a completion certificate.
