Why Choose Certass as your Certification Provider?

At Certass, we keep certification simple and straightforward, so you can get on with business. Our competent persons scheme offers the best value in the industry and payment is taken by monthly direct debit, so there’s no nasty surprise or big bills to pay at the end of the year.

Window and door installers get more benefits with Certass too, including membership of Certass TA, glazing’s largest trade association. Plus, you can tailor your certification and add additional scopes to certify the additional work you do with our Certass TrustMark scheme.

Each Certass installer certification scheme has been designed by tradespeople, for tradespeople to offer the best value, common-sense certification to installers and give consumer confidence in your brand. And we’re on-hand for friendly, helpful support whenever you need it.

Income from certification is only used for the benefit of our members, we don’t return it to shareholders and we don’t use it for swanky London offices. It’s used for the benefit of our members. We have provided some examples of monthly fees a typical Certass member with a good track record will pay per month for company certification.
