We called ERG ltd to repair a gas leak, but we were drastically overcharged and their engineer failed to repair it. We paid £205 for an engineer to repair our gas pipe after our kitchen fitter accidentally drilled into it. However, the engineer who visited told us it was a hugely complicated job, said ERG would charge us a lot extra to fix it and suggested we come straight to him once we had a price from ERG so that he could undercut them. However he wouldn't tell us how much he thought it should be. ERG still charged us the £205 even though all the engineer did was cap the gas, something the national gas service does for free. They then quoted us £714 for the repair, in addition to the £205 we'd already paid. This was appalling service. Clearly it was in the interest of this engineer to claim it was a complicated job, so that ERG would charge a lot and then he could do it for slightly less, directly. We called someone else who said it was a straightforward job and did the repair in under 30 minutes for a fraction of the cost. Terrible service and ERG refused to acknowledge that they misled us, not making it clear we would be charged regardless of the outcome of the visit.
