Understanding Overglazed Extensions

​

When a new or existing dwelling has a total area of openings (windows, roof windows, rooflights, and doors) exceeding 25% of the total floor area, it is considered an overglazed breach of the 25% rule as outlined in Approved Document Part-L of the Building Regulations. This scenario requires a specific process for Building Control approval to ensure compliance with energy performance requirements.

Our Compliance Process 

​

In straightforward cases, such as when architects provide clear instructions, the process is typically smooth. However, for most homeowners, the process is rarely this simple. But don’t worry – this is mostly the normal, even if your situation is more complex, so the below guidance is just that some guidance and not policy. 

​

We are experts in compliance for highly glazed extensions, a complex area where many others struggle. Our deep expertise means we can achieve compliance without sacrificing your vision, even with large glass areas.

​

Step 1: Initial Assessment

• We assess your project to determine if it exceeds the 25% glazing limit.

 

Step 2: Information Gathering

• We collect necessary details, including floor plans, glazing specifications, and any energy-saving measures.

 

Step 3: SAP Calculations

• Our experts use Standard Assessment Procedure (SAP) calculations to ensure compliance.

 

Step 4: Submission to Building Control

• We compile a complete SAP report for you to submit to building control.

​

 

Fast, Reliable Turnaround

​

Our typical lead times are just 2-3 days even for awkward extensions. For urgent situations, such as avoiding penalties or minimizing downtime on active projects, we offer a same-day priority service.
