Choosing a contractor purely on the basis of the cheapest quotation and the length of their own guarantee may not be your best option. Can your contractor provide you with assurances that their own guarantee will be honoured by a reputable UK based insurance company in the event that they cease trading?
If gambling with your house is not your thing and you prefer competence over cowboys, then choose a CGS Approved Contractor. CGS Approved Contractors offer Insurance Backed Guarantees from Guarantee Protection Insurance Limited; a UK based insurer which is regulated by the Financial Conduct Authority and the Prudential Regulation Authority, thereby providing the gold standard in consumer protection in terms of the strength of cover and extent of redress and recourse provided.
