Awful experience. Engineer came to service boiler, he incompetently FLOODED THE HOUSE with water leaking through the ceiling lights. He said he would call on Monday to discuss, he didn't. Didn't leave any paperwork for the service. Called customer service, they didn't know the engineer had messed up. Finally agreed to send an electrician to check our wet electrics a week later. I asked for paperwork 3 times, still not received it. Asked for another service as we don't know what has been done and no confidence in the first engineer. This was flatly refused, very poor customer service and gas engineer was very poor. Boiler service was overdue as they wouldn't let me book it for 2 months initially. Tried to charge us for electrician visit to fix their problem. They still haven't paid out for the lost time, damaged roof damaged tiles or kitchen units, this could take months. They haven't even offered a refund or someone to fix the damage. Seriously very badly handled and not worth the money. Other companies are cheaper and offer much, much better customer service. AVOID!
