We've just had window film fitted to our (very hot) conservatory, and have been taken for a ride by a company in Bromley. Be very careful if you're considering using this company - he not only only fitted about a third of the windows he invoiced for, he left without telling us and will not give us a refund. You have been warned. He only takes BACS in payment so we couldn't stop payment after he'd left once we had discovered what had happened. Basically he says whatever it takes to get the sale, WHATEVER it takes.
