DONT USE. Very poor performance. Charged me £200 for a call-out for a severe leak. They sent out a plumber who didn't even take the bath panel off, or look at any toilet or sink waste pipes, and pointed to some tile grouting and blamed it on that. Refused to refund when I went the next day and just fixed it myself with silicone (something the plumber should easily have done in 10 minutes). I'm not disputing the £200 call out if the chap did his job right, but if you cant use a silicone gun or take a bath panel off for a £200 call out and refuse a refund that is beyond a joke.
