Constantly lied to, been without heating and hot water for 4 days. Took a week to actually complete the installation, but I had my old boiler still connected, which they haven't now actually removed, due to it being "difficult" and told me I need to remove it myself. The standard of the workmanship Is to an absolutely shocking standard to say the least, they have damaged my property, including drilling large holes and filling them with silicon when they realised it was in the wrong place, burnt the door frames, wallpaper and ripped the bathroom Lino, they have water damaged the carpets, the list goes on. The fitters were only interested in how fast they could fit it and not the standard if the work, when I call the Doncaster office they always promise to call back, that NEVER happen. I constantly have to chase them, to top it off even the "Contracts Manager" Sam does not keep his promises to make sure someone comes out to rectify damage and sort out the heating. Please, please avoid this company at all costs, they are, in my option "bodge it and scarper" merchants that are only interested in the money. I will be making a formal complaint to the company on Monday and look at getting someone out to Rectify the heating and hot water issue and damage to the property and bill them, unfortunately my landlord paid the contribution in advance so cannot even withhold payment till it's sorted. AVOID AT ALL COSTS !!
