If you’re planning a home extension, loft conversion or even removing a wall, one of the most common—and most important—questions you’ll face is: ‘Does my project need Building Control approval?’

What Is Building Control Approval?

Building Control approval ensures that your construction work meets the minimum safety, structural, energy efficiency and accessibility standards set out by UK Building Regulations. These rules exist to protect homeowners, future occupants and the general public.

Approval is granted by your local authority’s Building Control team or by a private Approved Inspector. They check your plans, and then inspect the work as it happens to ensure it complies with the rules.

Projects That Usually Require Building Control Approval

If you’re doing any of the following, you’ll almost certainly need Building Control sign-off:

• Building a rear, side, or wraparound extension
  
• Converting your loft, garage, or basement
  
• Removing load-bearing walls
  
• Changing the use of a space (e.g. turning a garage into a kitchen)
  
• Installing new windows or doors where none existed before
  
• Adding a new bathroom, especially if plumbing is involved
  
• Making changes to the electrical system or plumbing
  
• Significant alterations to roof structure, floors, or foundations
  

Even internal reconfigurations (like moving walls or opening up spaces) can require approval if they affect structure, fire safety, or ventilation.

What Projects Might Be Exempt?

Some small projects might not need Building Control approval, such as:

• A detached shed or outbuilding under 15m² (and not used for sleeping)
  
• A small porch or conservatory (typically under 30m² and separated from the house by external-quality doors)
  
• Replacing fixtures like kitchen units without altering plumbing or electrics
  
• Some redecoration and non-structural cosmetic work
  

However, the rules can be nuanced, so we always recommend checking with a professional or Building Control before assuming your project is exempt.

Drawings Are Not Approval

Here’s a common confusion:
Having building regulations drawings prepared does not mean your project is approved.

These are technical drawings that show how your proposed design intends to comply with Building Regulations. Once completed, they still need to be submitted to Building Control, along with structural engineering calculations, for review.

During construction, Building Control will carry out a series of inspections at key stages—such as foundations, drainage, structural work, and insulation—to ensure the work complies with the approved plans and regulations.

Once the project is completed and everything is found to be compliant, Building Control will issue a Completion Certificate, confirming that your build meets the required standards.

What Happens If You Skip Building Control?

Skipping Building Control approval can create serious problems:

• Fines or orders to undo the work
  
• Delays in completing or selling your home
  
• Rejection by mortgage lenders or insurers
  
• Unsafe or substandard construction that puts you at risk
  

It’s always cheaper and safer to get approval before you start than to try to fix issues later.
