Part Q Window Certification Scheme

Our NEW Window Certification Scheme makes Part Q simple!

When supplying external windows to new build, renovation or refurbishment projects which require planning permission, you need to comply with Part Q. But having your own windows Part Q certified can be expensive and time consuming- so we’ve done it for you.

With our new Part Q Window Certification Scheme, you can manufacture officially UKAS tested windows simply by following our tested and certified section drawings, combined with with fitting only our tested and certified components list.

What is Part Q?

Building regulation Part Q / Document Q came into effect on October 1st 2015 and applies to all residential building, renovation or refurbishment projects that require planning permission.

All plans/building notices that are submitted after 1st October 2015 are required comply with Part Q, which relates to any window installed that is easily accessible. There are two ways to determine whether or not a window is classed as easily accessible:

  • If it has any part within 2m vertically of an accessible level surface such as an access balcony.
  • The window is within 2m vertically of a flat or sloping roof (with a pitch of less than 30 degrees) that is with 3.5m of the ground level.

Part Q identifies the use of PAS24 as the standard for window security.

What are the specific requirements for a Part Q Window?

To meet Part Q requirements, windows must meet new standards of robustness, use the approved hardware, and demonstrate proven security/performance.

Windows will meet requirement Q1 if they can resist physical attack by a casual or opportunist burglar by being both:

  1. Sufficiently robust
  2. Fitted with appropriate hardware.

Windows should be made to a design that has been shown by test to meet the security requirements of any of the following:

  1. British Standards publication PAS 24:2012
  2. STS 204 Issue 3:2012
  3. LPS 1175 Issue 7:2012 security rating 1
  4. LPS 2081 issue 1:2015 security rating A

Any test evidence used to confirm the security of a construction should be carefully checked to ensure that it demonstrates compliance that is adequate and that applies to the intended use. Evidence passed from one organisation to another can become unreliable if important details are lost. Small differences in construction can significantly affect the performance of a window.
