FENSA was established as a Competent Person Scheme (CPS) in April 2002 as a response to the Building Regulations for double glazing companies in England and Wales. As the market leader, FENSA is the largest and longest established Competent Person Scheme within the replacement window and door industry. We are fully trained and vigorously tested by FENSA, through practical and written exams. This means we are equipped with the skill and knowledge to isssue self-certified compliancedocuments under the Building Regulations without the need for a separate assessment from Building Control.

We strongly recommend you use a FENSA registered installation firm to carry out replacement works on your windows and doors. Firstly, this is to ensure your project is completed to high standards. Secondly, there is the reassurance that you are being served by an ethical company that cares about its responsibilities. And finally, you have the peace of mind that your windows and doors meet the relevant building regulations.

TrustMark is the Government Endorsed Quality Scheme. Being a member of TrustMark means that we are thoroughly vetted to meet required standards. It pays considerable attention and commitment to good customer service, technical competence and trading practices. This ensures that we adhere to and maintain these standards to increase consumer confidence and choice.

HomePro insurance issues 10 year insurance backed guarantees (IBG). We cannot stress the importance enough. Most contractors issue a guarantee upon the work they have carried out, the benefits of which are realised should you have reason to claim for faulty workmanship or material defections. However, thousands of contractors, large and small, cease to trade each year.

Our membership with Hompro give you peace of mind. Should we cease to trade at any point during the lifetime of your guarantee, you will automatically be covered by HomePro. Be sure to check this with trademens before you accept their quote.
