this firm is the most incompetdent i have come across.the job woz 2 take 4 taps off basin & bath & replce with new.i told the guy that the light in the bathroom was conected to an exactor fan & after 10 mins you get a burning smell so gave him a temporary light. he could not turn off the water to change the taps saing there was no service values & he would come back with sumone.he did not come back+there was service value on the pipes right at ground level. avoid like the plague.
