Leaking bath hot tap
The bath and taps were fitted before I moved in, so I don't have a clue what make or model they are and probably discontinued.
I have had a leak on the hot bath tap which has been getting gradually worse and is now a constant leak.
I took off the side panel but not sure where to go from here. The access is difficult and I'm not sure if it's an o ring, washer or cartridge or the size needed
I am in England. If I was to get a plumber in to fix it, What's the rough price I would be looking at paying. I am just scared I am going to get overcharged.
