We found this company frustrating to deal with, helpful one minute, very difficult to deal with the next. Strong on the sales side, but difficult to get them to fit our £3K fireplace, which the fitter left unfinished and left our flat without explanation. When we disliked one pricey aspect of the fireplace, the company was very reluctant to take any steps to remedy the problem. When it came to the gas test, at the end of the installation (3rd visit) the first fitter of two found a leak and blamed our builder who installed a supply pipe. Second fitter found that it was the first fitter's incompetence, not our builder's fault at all. No hint of apology at any stage of this frustrating process, which reached it's climax when the company 'forgot' to refund our initial £130 survey fee in its final invoice. One thing that gets 5* rating is Enviro Flame's online billing system - it demands 95% payment up front before they'd actually fit the fireplace, so when we found the fireplace left unfinished over Christmas we had nothing left but endless phone calls to unhelpful customer services. In the end, we had to pay our builder to finish the installation to our satisfaction.
