Renovation of 1bedroom flat
First week work in my flat was progressing , after 3 weeks when work wasn’t finished still l15% left of the items covered in the contract left but when I stupidly being naive and made a full payment. Archi / his team decided not to continue and without saying anything just disappeared, leaving me without agreed earlier electricity.. Now 5 months gone when I’m contacting Archie who didn’t return my reporting damages to my flat as result of Thornbury Crown work ( water leaks, floor swallowing, cracks in the walls, etc, ) I’m being ignored. Please avoid. Awful experienceVerified reviewerJob location: N110 General Building

Flat Renovation
I hired Thornbury & Crown for a full renovation of a project flat. Erti, who leads the team, was my main point of contact and supported me throughout a complex process. He was always responsive, patient, and clear—whether by message, call, or on-site. When issues arose or something didn’t meet expectations, he approached everything with a positive, solution-driven mindset. The final result is excellent. He also gave valuable advice to optimise the space and recommended trusted suppliers without pressure. I highly recommend Erti for his professionalism, reliability, and strong human approachVerified reviewerJob location: SW1VRFrancesco G10 Refurbishments

Bathroom remodel - Excellent experience
This company recently redid my bathroom and I couldn’t be happier with the result. They removed the old bathroom, completely redesigned the space, retiled, and even sourced all the materials. The price was very fair, the team was super friendly, and they stuck to the times they promised. Overall they were extremely reliable and I’m really pleased with the finished job. Highly recommend.Verified reviewerJob location: N2210 Refurbishments

Rear extension and kitchen remodel
Recommended by our local group chat and didn’t disappoint. They were very easy to deal with, communication and transparency from start to end was 10/10. Even when there were unforeseen events we were kept in loop and reassured. Project was on budget, on time and most important part of all - finished to an incredibly high standard. Would highly recommend. P.s. The kitchen was manufactured and fitted by ThorburyVerified reviewerJob location: KT10Response from Thornbury & Crown Ltd
