Absolute shambles! Do NOT use this company! Waste of time. Had an emergency with no heating and hot water due to boiler breaking down at 3:30pm, called ERG based on the reviews and services offered, was given a 4 hour window in which they would attend. Minutes before the 4 hours was up they called to say they couldn't come out that night. They then gave me a GUARANTEE that they would be here the following day between 9-4 and this would be confirmed by email. No email ever arrived. They also put the wrong town in the address which I had to call them to correct. Waited in all day, no engineer turned up. Phoned ERG at 4:05 and they informed me they would call back but they didn't. Phoned again at 4:45 to be told that the engineer wouldn't turn up that day, couldn't offer any assurance that they would be there the next day either. Apparently they couldn't get hold of the engineer to even find out what had happened to him, which I find somewhat unbelievable given todays means of communication. At no point was I contacted by ERG to be updated about the situation, they were vague and disorganised and they wanted to charge £125 an hour + VAT for the privilege of doing absolutely nothing! Appalling service, avoid like the plague. If I could give 0 stars then I would.
