FENSA Backed Guarantee and Promise

canon1

Canon Windows are a part of the FENSA insurance and guarantee system. Like ATOL or any other industry wide guarantee this means that when Canon Windows’ customers sign up for our products and services, they are also signing up for a guarantee that will protect all products and services purchased, any deposit paid and all other aspects of the job.

FENSA offers a series of guarantees to provide homeowners with complete peace of mind.

Our members eliminate the stress and worry associated with finding a contractor to carry out home improvements because homeowners know that only the very best, most professional companies are accepted into FENSA.


FENSA is famous for offering an impressive Ten Year Insurance-Backed Guarantee which protects homeowners’ investment even in the unlikely case that their installer ceases to trade. This is one of the most unique guarantees within the industry; it sets out clearly what is covered and what isn’t. There is no small print and no hidden catches – everything is open and up-front.
