gaby -so glad you recommended Milford .I had a problem with a radiator ,phoned him yesterday (Sat) and he was with me on Sunday morning . He sorted my radiator ,happily looked at some taps for me and will be coming back to fit a new pair and install some isolation valves . He was so nice ,easy going and clearly knows exactly what he's doing .Honest and kind . He says he works within the M25 circle .
