Be warned people...They sent an ineffective engineer who spend 5 minutes at my property & charged me £150 for an ineffective service I booked ERG to come & take care of a wasp’s nest at my property. The call was made at 9:00am and the man on the line said the engineer would call between 9:30am – 12:00pm. At 1 pm (with no sign of the engineer) I was told he was delayed & would come at the latest by 3pm. I re-arranged things so someone could be at the property. 3:30pm but still no engineer.... eventually he turned up at 4:10pm. At the property he seemed in a rush. He sprayed a small amount of application under the guttering, said the company would e-mail a receipt & then left. He was at the property literally 5 minutes. I had my doubts he’d done a proper job but waited to see. After a few days (with no decrease in activity) I contacted them. They said the engineer said it would take 7-10 days. They said to call back after that if the problem had not been resolved and they could discuss this with the engineer. 11 days later with no decrease in activity, I again contacted them. They then informed me they did not guarantee work, and that I'd have to pay again for another visit. So I still have a wasps nest, but I'm £150 lighter for it.
