Generally pleased with the boiler and Hassle Free boilers, however, they did fit the wrong boiler on the agreement after price and spec matching another plumber's quote. I called them as soon as I realised their error and they did offer to replace the boiler. I was suitably compensated and relatively happy. I'm yet to receive the shopping vouchers; I've called a few times now to chase them up (this was one of the selling factors when I was discussing getting it fitted). The last reason I got for not receiving them was a lack of communication between the marketing department. It's a poor excuse really as they seem to offer these quite readily. Hopefully I will receive these soon and then I'll be a much happier customer!
