Nail in pipe, so needed an emergency plumber quickly. Called ERG and a plumber turned up , who said we were lucky to have him. £180 per hour, charged full 2hrs for a job that he was there for 1hr and 8 minutes. this would have been easier to take had the work been done satisfactorily. The soldering he did was a temporary fix and the central heating did not work. Had to pay again to have the work rectified by a plumber recommended to me. He said the job was shoddy. He had to drain the system a couple of times to get the heating working. ERG customer service is awful, cannot get to speak to anyone, only through email. Total job cost £630, for a nail in a pipe. Please do NOT use them.
