“Chris, Darren and the team were excellent, professional, respectful and reliable. Carried out a full renovation and conversion over several months of a 4-bed terraced property into a 6-bed with 2 additional bathrooms. Quality of finish was top, pictures speak for themselves.”

Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 5 years on the register also points to an established business rather than a brand-new one.

Detailed reviews
House Extension
The team were great. Very polite and helpful. Not always the tidiest of workers and things were a bit rushed towards the end. The finished result is fab though.
Bathroom Installation
Chris and his team renevated both my bathrooms - main and en Suite as we had trouble selling our property and they were in quite bad condition. We were really happy with the work. They delivered on time and the bathrooms look amazing. They worked to tight deadlines and made sure we were happy with the final product. We also sold our house on the Monday follwing completion of the work Friday.
Complete Bathroom Refurbishment
We were very impressed the whole team were fantastic they worked really hard, the house was left clean and tidy and our bathrooms are Fab! We would highly recommend Tuner Renovations

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.
