Our Credentials

Our high standards, excellent customer service and quality products speak for themselves. With more than 40 years of experience behind us we have steadily built a reputation for quality and reliability.

Not only do we have a strong reputation, but we also have the certifications and approvals of a number of independent official bodies to prove it.

BSI accreditation

Our products have been tested and accredited to standards set out by the BSI Group, formerly the Engineering Standards Committee, which helps organisations improve their quality and performance, maintain their reputations, and help them be more sustainable. Our BSI accreditations mean that our customers can relax in the knowledge that they’re in expert, safe hands.

Secured by Design

Our products achieve the requirements of Secured by Design, the official UK Police flagship initiative that supports and promotes the principles of crime prevention through secure design and engineering. So Swish Windows & Doors customers can rest assured that they are investing in some of the safest and most secure products on the market.


We’re members of PVCAware, a British Plastics Federation initiative that promotes knowledge about PVC-U and promotes the advantages of the material in terms of performance, energy efficiency, durability and longevity, as well as the environmental good sense associated with replacement PVC-U windows and doors.

With all these accreditations and certifications it’s no wonder that we’re one of the UK’s leading suppliers of PVCU windows, doors and conservatories, with a reputation build on experience, expertise and total reliability.
