Our boiler was making a noise so we called ERG who said they would send someone at an hourly rate of £125 plus VAT. He arrived, told us we needed a new fan which he would need to order. He was only with us for 15 minutes and we got charged for the hour. Don’t ever go through a call centre, they know how to rip you off. When the engineer returned with the fan it was the fan plus another hour plus VAT. The boiler is working well again but we will never use ERG again. I don’t know how they can charge such exorbitant prices. I have to say the engineer knew what he was doing and was very pleasant and friendly.
