Unique Windows is NOW a Certass Approved Installer

What is CERTAS?

Certass is known as a competent person scheme for the glazing industry. As a registered installer with Certass, Unique Windows have been vetted, verified and checked rigorously to ensure we are properly qualified to conduct the installation of a range of home improvements, including replacement windows and doors.

As an appointed member of Certass we ensure that all works are registered and lodged with Certass, so that they can be registered to the relevant local authority. This will ensure that you as the home owner are supplied with  the relevant Building Regulation Compliance Certificate for the works undertaken and provide you peace of mind that the works have been conducted to the required building regulations. The certtificate will be important should you decide to sell your property in the future as your solicitor will require this documentation.

As part of the vetting process, Certass have probed into all aspects of the daily operation of Unique Windows, including their Insurance policy, guarantees supplied and the insurance backed schemes that Unique Windows supply to their customers. This ensures another avenue of reassurance for you  the customer  that Unique Windows has worked to a leading industry standard and adheres to strict guidelines in how it operates.

For added reassurance Certass will continue to monitor, inspect and audit Unique Windows to ensure we maintain our standards as we continue to grow our brand.
