Do not use this company under any circumstances, the product is superb but the fitting teams they use are worse than useless I have had a full roof fitted twice by these cowboys as well as 7 revisits to try to stop leaks. The guarantee is worthless as they have now changed the name to comfortable marketing and state that they are no longer obliged to honor the guarantee. I have never had the same fitter twice as they seem to get rid of them and one team actually burgled my house whilst they worked on the conservatory. This company should be ashamed of the service it offers
