Detailed reviews
We recently had our bathroom renovated and couldn’t be happier with the results. From start to finish, Kosta was professional, reliable, and extremely skilled. Communication was clear throughout the project, and every stage was completed on time and to a very high standard. The workmanship is outstanding. Tiling, plumbing, and finishing touches were all done with real attention to detail. Kosta kept the workspace tidy each day and were respectful of our home, which we really appreciated. Our new bathroom looks amazing, and the quality speaks for itself. We would happily recommend Kosta.
Kostas (and his colleague Daniel) did an absolutely perfect job in a really short amount of time, despite it being a large job and the tiles being more complex than usual. Kostas is a lovely guy - he is a very good communicator and very professional, always reliable and on time.
Kostas was excellent- tidy, professional, punctual and most importantly could give instructions and he knew immediately what was needed. He is fast and efficient 11/10 My only criticism is that I don't want to leave such a positive review because he will get booked up and not be available for me. In this day and age - Kosta is a refreshing breath of air - giving classic workmanship with traditional values - We also felt very safe and comfortable with him in our house - which is important . Its a no brainer. Anthony Mann

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
