Awful people. They gave a quote over £4,000, they were told it was too expensive, they said because they had a job in the area (15miles away, in London traffic is not in the area) they dropped it to £3,249. Said no to that, he then dropped to £2,600. Got a call from the sales team the next day, said they had looked at the priced and were found some savings and offered it for less. Every other installer is quoted around £1,000-1,500. I remember by dad telling me about double glazing salesmen in the 80's and before, with this attitude. I thought that sales tactic would have died out at the turn of the century.
