5 Best Basement Renovation Services in Leeds Known for Clever Remodelling Hacks
I attended my friend’s party, and I was floored! It was held in his newly renovated basement, which looked like a trendy bar and lounge, complete with a small bar, plush seating, a pool table, as well as swanky lighting and a killer sound system.
Needless to say, I was totally jealous. Who knew his once dingy basement could be transformed into a luxe bachelor’s pad?
That totally inspired me to write this article. Here are the best basement renovation companies in Leeds that’ll flawlessly extend your living spaces.
How much does a basement renovation cost in Leeds?
A basement renovation in Leeds usually costs between £15,000 and £60,000 or more, depending on the size, design, and complexity of the project.
1. Back To Basement Ltd.
Address: 8 Kingswood Grove, Roundhay
Phone: +44 7930 360880
Business hours:
- Mon – Fri: 8:30 AM–5 PM
Back To Basement was established by Rubi Kasuto in 1997. His company specialises in turning damp cellars into fully functional living areas across West Yorkshire.
They always begin with a complimentary site visit, during which Rubi personally examines critical structural factors such as moisture levels and foundation depth.
Then, his team directly coordinates with Leeds City Council’s Building Control department before any construction kicks off. We love that they handle the entire regulatory and inspection pipeline on your behalf.
Upon completion, you’ll even receive a full documentation package, including a Triton waterproofing guarantee and a NAPIT electrical certificate.
Sure, their basement renovation services might be a bit steep, but most of their clients believe their services were worth it.
The quality of their work speaks for itself
“Rubi, Tal and their team transformed our dingy, unusable basement into a beautiful new level of living space in our Victorian terrace. They created a fantastic area with a downstairs shower room and a snug/bedroom, and also renovated our entire ground floor – fitting a new kitchen, replacing a window, installing a new ceiling, and laying a stunning herringbone floor throughout. They were reliable, trustworthy, tidy, and an absolute pleasure to work with. I wish all builders were like Back to Basement! Four years on, our basement conversion is still rock solid, and the quality of their work speaks for itself. They truly transformed our home, and I only wish they could renovate our next one. I couldn’t recommend them highly enough.” — Alice Chan, Google Review
Converted the basement into bright, usable rooms
“Rubi converted the basement from a damp and dingy dumping ground to three dry and bright usable rooms. The team are a great bunch of lads, and it was a pleasure to have them in our house. The quality of the work was very good indeed, and Rubi has been easily contactable after the work was finished to sort out a couple of minor issues. We use our new rooms every day- it has completely transformed our house. Thanks!” — Stuart Maguire, Google Review
2. Lynch Renovation and Construction
Address: 33 Great George St
Phone: +44 7304 063002
Business hours:
- Mon – Fri: 8 AM–6 PM
Lynch Renovation and Construction is a family-run business that handles both residential and large-scale commercial contracts under its insurance policy. Amazingly, they’re also known as one of the top renovation contractors in the city!
As established local specialists, they begin each job with an in-depth consultation and site survey. They then construct a renovation strategy and project schedule based on your specific budget and structural needs.
They even clarify the fixed quote and timeline for your basement project before starting. Any project alterations are approved in advance, so you don’t have to worry about unexpected financial surprises mid-build.
Our favourite part of their service, however, is their affordable pricing—they source materials strategically and maintain low overheads to deliver competitive rates.
Understandably, their solid rep and comparatively lower contractor rates mean they can be quite hard to book during peak seasons.
We are so happy with the results
“Andy and the team did a fantastic job on our building work. The team took time to work with us on the designs, coordinated the whole project, and nothing was too much trouble for them. They were very professional, and the work they did transformed our home. We are so happy with the results.” — Laura Roberts, Google Review
I’ve used Andy for probably 20 years now
“I’ve used Andy for probably 20 years now on and off whenever we’ve needed any building work on our properties, he’s always been very reliable and undertaken all sorts of different works for us. I have recommended him to so many people over the years and always had great feedback” — Andrew Gaunt, Google Review

What’s cool is that every project comes backed by a 10-year guarantee to safeguard your home against future moisture issues.
Just be prepared for their contractor rates. We heard that their fees can be a bit pricey compared to other basement renovation firms.
No corners were cut, and a high standard was maintained
“Paul and his team did a fantastic job on converting our basement during a very tough time regarding the cost and supply of materials. Although it took him and the team longer due to the material shortage and the cost increased on their side, no corners were cut, and a high standard was maintained throughout the build. We would highly recommend Below Ground Interiors to anyone looking for a basement or cellar conversion.” — Joe Griffiths, Google Review
I would thoroughly recommend him for anything basement-related
“Had a small issue with a leaky basement in one corner of my cellar. I contacted Paul, and he was really helpful. He gave me a very simple solution to my issue, and now it’s fixed! Paul is very knowledgeable in his field, and I would thoroughly recommend him for anything basement-related. I only wanted a small fix as I was selling my house, but I have left his details with the new buyers as they are interested in doing a full conversion down there, and he’s the man to it. 😊🙏🏽” — JoJo Kelly, Google Review

I liked how well and tidily they worked
“NX build & renovation was suggested to me by a friend. I needed to do an extension in the back of the house, called the company and had a quote. They did an excellent job. I liked how well and tidily they worked. Since then, I have done more jobs at home. Did the porch in the front door, did a pergola in the back garden. Removed and renewed the boiler and radiators. Woodwork in the basement, and we did the bathroom renovation.” — Leonard Brahimlari, Google Review
