Before Work Begins

Window Tech Certass certified contractors will provide you with a seven day cooling off period. This means that, should you change your mind about the works you have legally agreed to, you can exercise your right to cancel the contract within seven days by writing to the contractor directly. We would recommend that this is sent by recorded delivery.

Window Tech contractors will provide you with protection to cover your deposit through an independent insurance backed guarantee provider.

After Completion

Window Tech contractors provide all of their customers with a written guarantee with a duration of 10 years. Furthermore, we are able to provide you with additional piece of mind in the form of an Insurance Backed Guarantee. This covers the contractors written guarantee in the event that we cease to trade.


Once the work has finished, Window Tech contractors will register your installation with Certass within 30 working days of the installation being deemed complete.

On your behalf, Certass will notify your Local Authority of the replacement window and door installations completed at your property address. Certass will issue you with your legally required Building Regulation Compliance Certificate as proof of compliance. This will be required by your solicitor should you wish to sell your property. If you've lost your certificate, either you or your solicitor can contact Certass directly and order a replacement. There is a small charge of £10 including VAT for replacement certificates ordered 28 days after original issue date.
