I contacted ERG in an emergency because we had a burst pipe with water pouring over the floor. They said an engineer would be with us within 4 hours. After 2 hours they phoned to say that they could not get an engineer. They had taken my card details when I first called then said they would charge £145 + VAT per hour plus materials. This is extremely expensive and certainly does not fit with the words on their website: "very competitive local rates". Luckily I was able to contact a local plumber who arrived in under one hour, replaced the burst pipe fitted a stop valve and only charged £95, so ERG's failure turned out to be blessing in disguise! After I made the call to ERG I discovered they are located in Southend-on-Sea which is hundreds of miles away from my location, although they appeared to be local when I did a Google search looking for help in a hurry. My best advice: avoid this company and look for a genuine quality local trades person to eliminate the unnecessary and excessive ERG handling charge.
