Conversions - General- 2 Nov 2025
Access and Mobility Bathrooms were outstanding from start to finish. What began as a tricky idea to create a bedroom extension and utility area from awkward old Victorian rooms (with damp and every possible challenge) has turned into an amazing space that exceeded all expectations. Lee kept in regular contact, gave clear timescales, and offered great suggestions whenever we ran into obstacles. Every member of the team was polite, professional, tidy, and worked to an exceptionally high standard. Their attention to detail, cleanliness, and “can-do” attitude made the whole experience stress-free. The finished room for my son and the fabulous utility and toilet are beyond what I hoped for. I’d recommend this company without hesitation!

Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

A job well done! Georgi was great & Very professional. He brought a partner along who also mirrored the same level of professionalism. I was quoted a fair & competitive price, both men showed a great level of patience. I have used my builder on multiple occasions, and I would say this was the first time I was genuinely pleased to this level. Thank you Georgi!

Jason has been great, from this job I have gone on to hire him to also fit the kitchen. Both him and his team are highly knowledgeable and proactive. I have been extremely impressed with the progress they have made, their transparency and keen eye for detail. Every day they have left the house incredibly tidy considering building work inevitably creates a mess. I will be hiring Jason for future work and would recommend him and his team to all!
