I had a major leak in my bathroom, water coming out under mains pressure from behind the toilet. My regular plumber just said he wasn’t working during coronavirus lockdown so I searched Which? and found GS Heating. Left a message and within half an hour Ben phoned me back and arranged to come round. Within 4 hours of my phone call, the problem was fixed, toilet working again, very reasonable price. Ben is very professional and knowledgeable.
