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
A basement conversion has the potential to add a lot of value and space to your home. Once your team excavate your new basement, you can turn it into a bedroom with an ensuite bathroom, a new gym, a living room, or any other living space.
Transform your underground spaces into useable rooms with the help of a skilled cellar conversion specialist in your local area.
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
A local basement conversion specialist is more likely to respond quickly as they’ll be right around the corner and ready to help.
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.
Do I need planning permission for a cellar conversion?
You won’t need to apply for permission for a cellar conversion, as long as:
- You’re converting an existing residential basement into a living space
- How you’re using it isn’t significantly different and the basement isn’t a separate unit
- You don’t alter the external appearance of the property, such as by adding a light well
- You don’t live in a listed building
Excavating a brand new basement which involves major works is likely to require planning approval.
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.

Questions to ask before you hire a basement conversion specialist
Whether you’re looking to build a brand new basement or simply want to extend or improve your existing cellar, there are a few questions you should ask before you hire a specialist to excavate your new room:
Do you have public liability insurance and what does this cover?
While it’s not a requirement for them to have it, it’s a good idea for your basement conversion specialists to have public liability insurance to cover you and them against any accidental damage done to your home or personal injuries. Make sure to always ask your tradespeople what insurance they have before you hire them. This will guarantee protection for both parties.
How many years of experience do you have?
Knowing how many years of experience your basement conversion specialist has will allow you to pick a tradesperson who you are confident has enough experience to carry out a high quality job. When you’re finding a tradesperson through Rated People, head over to their profile to check out the pictures on their work gallery and their ratings and reviews.
Do you use subcontractors? If so, are they licensed and insured?
Your basement conversion specialist is likely to employ subcontractors. It’s a good idea to confirm the qualifications and insurance coverage of everyone who will be working on your project, including surveyors, structural engineers and electricians. Anyone working with gas needs to be registered with Gas Safe, and anyone installing electrics (in England and Wales) needs to be Part P certified to be able to self-certify their work. These tradespeople will have valid documentation that you can ask to check.
What is your estimated timeline for completing the project?
Knowing what the estimated timeline for completing the project is will help you set realistic expectations about how long your basement renovation will take to complete.
How much will the job cost?
Asking how much the job will cost will help you budget for your project and will ensure price transparency before you hire. How much you’ll end up spending depends on the scope of your project, and where you live in the UK, so make sure you add plenty of details when you post a job.
We want to assure you that you can simply stand by and safely watch your work being completed to the highest quality in the shortest possible time. We have ten years of experience in this line of work. Just send an email or give us a call to get your quote and ask any questions

Neale is lovely to deal with whilst being professional, punctual and skilled. I didn't believe builders like this still existed. He turned up on time, every single time he said he would. He produced a detailed written quote and then didn't increase it throughout the job. He and his side-kick, John, worked non-stop overcoming every issue our wonky victorian terraced could throw at them. I'm so relieved and impressed. He's now my go-to builder.

I cannot recommend Grigore and his team highly enough. After a long-term tenant left my property in a terrible state, I urgently needed a builder who could work quickly and efficiently to bring the house back up to a high standard and minimize void periods. Grigore provided a fantastic quote and started the job within a day. The results were nothing short of exceptional. Even the estate agents who came to value the property were thoroughly impressed, and I’ve since received multiple offers. Thank you!!

Colin from cam construction was extremely helpful with our quote for potential extension work to a home we were looking to purchase. He made himself available for a specific appointment at the property, gave us some great ideas for what would be possible then fully costed it up, and even accompanied it with a proposed planning drawing. The service we received was extremely professional. We haven't been able to go ahead with the purchase for unforeseen reasons, but would recommend cam thus far.

HEX360 was founded in 2015 by Craig Lewis with the solid foundation that a degree in construction management provides. Before launching HEX360, Craig’s former life saw him working at Princess Yachts, where he founded his skills and acquired his particular attention to detail – but if you’ve reached this page, you probably aren’t interested in hearing Craig’s life story… you’re really interested in finding out what makes HEX360 different to all the other construction companies out there. So read on and discover our difference. Working with most construction companies can feel a bit like finding your way in the dark – you just don’t know where to go to get the information you need. The stereotypical construction company that makes matters so confusing and complicated that everything they say goes over your head is, unfortunately, not just a myth. They’re out there, and they’re confusing clients as we speak. So, it’s no wonder that so many people put off their project or come to a grinding halt partway through – after all, it can all feel just too overwhelming. Luckily, HEX360 is here to change your perceptions and prove that not all construction companies are the same. We’re dedicated to working with you, not for you, and that means taking a collaborative approach right from the get-go. With our 8-step process, we’ll clearly outline every stage of your project so you won’t feel overwhelmed, and thanks to our use of in-house project management software, you’ll have complete transparency for every aspect of your project. We are committed to flexibility, accessibility, and approachability so your project can run smoothly, whether you’re updating your kitchen, renovating or extending your entire home or developing a large commercial property. You’re more than a number on a spreadsheet to us, and we never bite off more than we can chew. Our attention and efforts are solely dedicated towards you and your project during your time with us. Unlike with some construction companies, once we begin work on your project we don’t simply move on to our next. We provide industry leading account management during the full life cycle of the project, meaning you aren’t forgotten about once you sign on the dotted line.
