I was constantly topping the system up, with the boiler pressure water gauge dropping and switching the boiler off after a few weeks.
Michael,the gas engineer,arrived on time and quickly found the problem with the boiler. He checked the emissions with his equipment and then cleaned up after himself.
He was very professional with his repair and a pleasant fella to talk to.
I thought it was a problem with leaks and it would cost a fortune, but no. He doesn't overcharge for his work.
I would recommend him to anybody.
