What’s Special about a Construction Guarantee Contractor?

Well, where do you want to start? All CGS contractors are independently vetted against a checklist of over sixty three standards they are expected to meet and only contractors showing a high degree of technical competence, a full knowledge of current Health and Safety regulations (to protect you the customer) together with financial stability and probity, are eligible for membership.

Our Contractors

It's common sense that in order to protect himself, the Underwriter wants to be backing the best when insuring their work in your home.

And the benefit to you? Peace of mind for up to twenty years, knowing that even if the contractor goes out of business for any reason, subject to you having the correct documentation, the insurance company will stand in his place. CGS issues an insurance certificate specific to your property on behalf of the Insurer.


Many contractors offer “insurance-backed” guarantees which is not insurance. See FAQ No 4
