Accreditations

Established for over 10 years, Perennial has achieved a reputation for high quality and standards.  We are one of the few companies in this industry to attain ISO 9000 registration and are also Fensa registered.
Unlike many companies’ hardware which is only guaranteed for 12 months, all our products including profile, glass, hinges and handles carry a full 10 year guarantee.
90% of our work comes from recommendation. Our customer service policies provide consistent standards and a service second to none. We never take deposits, only payment on completion, we don't use any fancy gimmicks or offers and we don’t employ salesmen. All our workmen are retained employees and we do not use subcontractors, so we are able to maintain consistent standards of workmanship. 
Perennial Windows has been using the same suppliers for the last ten years. Our strong relations with Shepley Window Systems and System 3 Ltd ensure  you have the best and most consistent quality and security in the industry.
