Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

How to find a reliable, local basement conversion specialist
What does a cellar conversion involve?
If you already have a basement, then you might be looking to turn it into a liveable space by adding structural supports, damp-proofing, insulation, heating, and a new ventilation system. If your cellar was intended for storage and has low ceilings, your basement conversion team might have to dig down to increase the head height before they can add things like new plumbing and electrics.
Or, you might be thinking about extending your current basement, such as by digging underneath your garden. This is another great way to add more space and additional rooms to an existing basement.
If you don’t currently have a basement, you can also create a new one by carrying out excavation work. As well as the basement, you’ll also need a new staircase.
Whether you want to build a cellar from scratch or want to turn your cramped storage room into a brand new living space, a basement conversion specialist can help.
Factors to consider before hiring a basement conversion specialist
On average, a basement conversion can take anywhere from 12 to 20 weeks to complete. Avoid stress and costly repairs down the line by hiring a skilled specialist to help you upgrade your home. Look out for basement conversion installers that:
- Are a skilled company with a strong history of high standard projects
- Have all the licenses and insurance needed to protect you and their workers
- Have a good range of positive reviews from previous customers vouching for their reliability
- Are available to carry out the work in the timeframe you need it by
- Are quoting a price and payment option that you are happy with, having compared the quote with other basement conversion companies
How much does a basement conversion cost?
If you don’t have space for a rear or side extension, and don’t have a loft to convert, then a basement conversion is a great option to maximise your home’s space. How much you’ll end up spending on your basement conversion depends on a range of factors, including:
- The size and layout of your basement
- How many structural changes will be needed, including extra support beams and underpinning
- Waterproofing and damp proofing costs, as well as the installation of effective drainage systems
- Whether you want a window well installed, which can help you introduce light into your basement
- Basement insulation and soundproofing
- Labour costs, which are affected by where you live in the UK
The average basement conversion costs between £120,000 and £160,000. For a more accurate quote for your specific project, speak to a basement conversion specialist today.
Other basement conversion FAQs
Do I need planning permission for a cellar conversion?
You generally do not need planning permission if you are converting an existing basement into a living space without changing the building's external appearance. However, you will likely need approval if you are excavating a brand-new cellar, creating a separate living unit, or working on a listed building.
For more information, contact your local planning authority or visit the Planning Portal website. You can also read our planning permission guide for more information.
What questions should I ask before hiring a basement specialist?
Always ask if they carry public liability insurance, how many years of experience they have, and for a detailed cost breakdown and project timeline. You should also confirm if they use subcontractors, ensuring any gas engineers are Gas Safe registered and electricians are appropriately certified.
What is a sump pump, and do I need one?
A sump pump is a drainage system installed below the basement floor that automatically pumps out any groundwater that collects under the property before it can flood your room. Because cellars are naturally below the water table, a sump pump paired with a waterproofing cavity drain membrane is almost always required to ensure your conversion stays completely dry and structurally safe.

BTR were awful. They delayed, double charged, installed the wrong items, left footprints on doors, and told me they had done the works when they hadn't. I was desperate for the works to be done properly as I was selling a house. They haven't paid me back the money I paid them to complete. I had to get someone else in because the standard was so low.

Quoted but just too expensive
We hired Ionut to lay some decking and build two planters and some bench seating as well as landscape the garden and laying a new lawn. Ionut and his team did an exceptional job - the work is very neat and professional and we ended up with a great finish. They were polite, respectful and worked very hard. I have already recommended Ionut to a friend and hired him for another job (laying slate slabs) which was also done incredibly well.
