My heating/hot water went out on Christmas day. I reported the issue to my letting agency, but it being a holiday service would be delayed multiple days. British Gas was unable to make it out until almost a week later and the emergency number for my letting agency was never answered. I posted a status on a local Facebook page looking for a plumber and multiple people tagged Elements. I called them Boxing Day evening and described the issue, they were able to figure out what was wrong simply by the description. The following morning Elements arrived promptly and immediately got to work. An hour later the circulation pump had been replaced and the heating/hot water was working again. I was even given advice on some upgrades which need to be made to the dated system. I would definitely recommend Elements for your heating needs.
