Contact Aria (AFE) after seeing recommendations on this forum. They helped to fix a leaking shower unit. They were very friendly and helpful. They detected the leak and stopped it. Then they installed the new shower and replaced tiling. After a couple of weeks the tap was dripping due to a problem with a faulty washer from manufacturer. They came round the same week to stop the drip and replace washer. Work was finished to a high standard. Communication was excellent throughout and I would definitely recommend.
