Please read the negative reviews before booking with this company. I went with them as was offered a cash incentive through my utility provider but it has cost me more than this in outlays. Three weeks down the line I have no working boiler . They are now trying to charge me and extra £200 for an electrician to fix a fuse spar that was working perfectly fine prior to installation. I raised a complaint last week but no one wants to take any responsibility.. they do not have their own engineers they ring up random engineers in your area so it is a hit or miss who you get and when there is an issue they are not equipt to deal with it
