We are delighted with Tim’s excellent and professional service in fitting a replacement radiator and clearing a problem drain for my elderly mum. He responded straight away with his quote and I found him very reassuring when he explained on the phone how he would carry out the job and how he was able to complete the job within a week, which was perfect timing for us. He was friendly, efficient and completed the job to a high standard. We are very happy and would thoroughly recommend without hesitation.

Fired him for appalling work, no-shows and delays; see his other bad reviews. He's a middle man; does not do any work; got others to do it like a plumber, then a tiler the next day; slow work made worse when someone messed up or did not show up. Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel. Materials I paid not returned; take every receipt and check you keep/use every item as he will even for wipes/tape
