PART Q Certification

What is Part Q?

Part Q is part of the Building Regulations 2010 (Updated 2015), which sets a minimum-security requirement of windows and doors in new dwellings. This aims to reduce the risk of unauthorised access.

Our Part Q Approval

In 2025, we achieved Part Q approval through Coastal’s Part Q Scheme. This requires windows and door sets to be manufactured to an approved design that has been tested to meet the security requirements of PAS 24:2012.

Our approved joinery systems:

  • Are tested to PAS 24 security standards
  • Include secure glazing, fixings, locks and hinges
  • Are suitable for use in new-build residential projects
  • Meet Building Control requirements without additional justification

This applies to our compliant ranges of:

  • Windows
  • External doors

What This Means For You

  • Peace of mind on security and compliance
  • No need for additional testing or evidence
  • High-quality joinery without compromising on design
  • Faster Building Control sign-off

Bespoke & Design Flexibility

Part Q compliance doesn’t mean limited choice. We can still offer:

  • Bespoke sizes and configurations
  • Traditional or contemporary designs
  • Finished, glazed and ready-to-install joinery

If your project requires Part Q, feel free to get in touch with any queries.
