BSI Kitemark Approved

Barnet Window Company - BSI Kitemark Award

We are a proud member of an exclusive group of companies nationwide, who hold the prestigious Kitemark for window installations.

Why choose a Kitemark installer?

As a Kitemark Installer we are constantly monitored by the B.S.I. to ensure that high standards of design, product quality, service and installation are continually met. We ensure that our standards never slip an inch so we carry out our own comprehensive 22 point check on every single one of the windows and doors that we install.

If you’re thinking ‘Kitemark? Every window company has those, I always see the logos plastered over their adverts…’, remember, this Kitemark is not just for a particular part, or pane of glass, or screw in a handle; this Kitemark is an overall accreditation for every little detail of our entire fitting service. NONE of the large national companies have been awarded this prestigious accolade.
