Fensa-Approved Window Installations in North London, North West London and the Surrounding Areas

When you’re making home improvements, replacing and installing new windows should only be carried out by a company you can trust.

BDL Contractors Ltd are proud to be Fensa approved, this means that as a company we’re regularly monitored and re-assessed to ensure that we’re meeting the high standards and building regulations that all window installers need to adhere to.

Fensa will only endorse companies that pass an independent assessment and who conform to energy efficient building regulations as well as also providing a high standard of service.

Fensa Certificate

Every window installation we carry out comes with a Fensa-approved certificate. This will give you the verification that your warranty is insured and the peace of mind that your installation has been carried out to a professional standard.

The Fensa Certificate confirms that your new windows are both energy efficient and have been registered by us with your local authority and that they comply with building regulations. You will receive your certificate within 2 to 4 weeks after your installation is completed.

You also have the peace of mind that your certificate never runs out, providing your double glazed windows are still in place, your certificate will still apply. This is also the case if you decide to sell your property, the certificate can be transferred to the new homeowners.
