Avoid at all costs. Unlike all the good reviews for this company, we've had a terrible experience. We've booked them for a boiler service and within minutes he said our boiler is leaking carbon monoxide, but for 360 cash (or 450 bank transfer) he can fix it on the spot. Or replace for 2000 cash (2500 transfer). He said our boiler needs condemning and turned off the gas. He did not turn off the boiler or put any stickers up (as per gas regulations). He also added that the boiler might catch fire or explode. When we refused his service, he just left. A proper gas engineer came to check the boiler and there is nothing wrong with it. We also have a carbon monoxide monitor and it reported no leaks. We have yearly services and this has never happened to us. Absolute cowboy. Fortunately we only lost 80 pounds cash and a few days without hot water. I dread to think what would have happened if it was winter.
