About Us

Rainbow are a leading local company that prides itself in the care and quality of service and installation. We are all very down to earth and straight forward people, who will treat you with respect and importance, not just a number on a file!

We have been established since March 1992 and have given tens of thousands of local people two decades of high quality installations, and equally as important, prompt and professional after sales service. All of our products are produced to the highest possible standards in the most up to date factories to all of the relevant British standards.

We are members of The Guild of Master Craftsmen whose major objectives are to promote high standards of quality and service in all aspects with utmost care and consideration. Whether it be conservatories, windows, doors, porches, or roofline products, we at Rainbow will help and advise from day one to make your installation run smoothly.


As we are of course, human, we do make mistakes but have a service department dedicated to putting things right as soon as we possibly can, with as little fuss as we can.

You may not see Rainbow as heavily advertised as most other companies as we work mainly from recommendations from existing customers. We hope that you agree that word of mouth is the best and cheapest form of advertising, hence we can keep our overheads to a minimum and pass the savings onto our valued customers.
