Do extension builders near me need insurance?

While it isn’t a legal requirement, most builders carry public liability insurance to cover accidental damage or injury during work. Always ask to see proof of insurance before agreeing to a project.

Do local extension builders offer guarantees on their work?

Yes, many local home extension builders in your area should provide a guarantee covering their workmanship for a set period, often lasting several months to a few years depending on the project size. Always check what the guarantee covers before work begins.

What should I ask before hiring an extension builder?

Ask about previous work, project timelines, cost estimates, and payment terms. It’s also wise to discuss materials, planning permissions, and how any unforeseen issues will be handled. You can easily view examples of previous projects of extension builders near you on MyBuilder.

How much deposit should I pay for an extension project?

Deposits usually range from 10% to 20% of the total cost. Make sure the payment schedule, scope of work, and conditions are clearly written into a contract before the extension project starts.

Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Oto has been completing work for us for a while now. Work has included kitchen fitting, hanging doors, general maintenance and all sorts of carpentry work. Oto's skills are amazing, as he trained in Japan and worked there where a lot of building and carpentry work doesn't use nails and uses interlocking techniques. So his work is incredibly well detailed and very accurate. We have always been more than happy with his work and would absolutely recommend Oto to others.

The work was quite a big project and went really well with minimum disruption. They carried out the building of a single storey extension to the house and a new brick double garage. They also included the full renovation of the existing house. New floors & ceilings, added a new en-suite , returned 2 bathrooms, new fitted kitchen, electrical rewire, plumbing and left the work in a completed beautiful finish, the work was very well managed and more than happy with the workmanship, would definitely recommend.

We asked Ryan to board and plaster a bedroom with a sloped ceiling. Ryan was incredibly efficient, helpful and thorough during his work and was also very punctual and reliable. We've asked Ryan to return and complete some additional work at our house as we were very impressed with the quality of his work.

We required two extensions - to the rear and above the garage at the side. We contacted Darek as he was recommended to us by a work colleague who lives in our area. We found Darek's prices to be competitive and he was very reasonable to work with, being flexible when our plans changed slightly. Having building work undertaken is never a pleasure, in our view However, we're pleased with the completed work and we found that working with Darek was as stress-free as it could have been. We would (and have) recommended him to friends.

Dan and his partner have carried out a large amount of work on my property in stages over the last seven years. This work has included internal structural building work, removal of walls and ceilings, fitting Velux windows, creating made to measure shelving, and the opening out of a fireplace. This year, a new bathroom was fitted, and Dan completed all the tiling work. He has also supplied and fitted new high quality fences after storm damage. Dan's workmanship and professionalism throughout has been of a very high standard. He is only happy when the job is done correctly, and the site is cleared and clean. Dan is a reliable trades person, arriving as arranged, on time, and working efficiently. He shows consideration for his customers, and will attempt to minimise any disruption during building work. I strongly recommend Dan's company for inclusion on your website.

I decided to have an annexe built on the side of my house. Contacted Tom as was recommended through a friend. I left the job in Toms hands, ordering materials, diggers and scheduling deliveries like the concrete pours, and arranging visits from building control. I was very happy with Toms work, very punctual, trustworthy, work was done to a high standard in a good time frame. Was lovely to watch the job evolve as I work away all week. Building control were very happy with his work and signed the job off without any issues. I would highly recommend Tom for his knowledge and expertise. Im very happy with the job and the standard of finish. Thankyou

We have known and worked with Joe for the last 6 years. He has recently built a ground floor kitchen extension and created a utility area and downstairs cloakroom for us. His ability to communicate each phase of the build’s requirements is brilliant. His craftsmanship is impressive. He has the ability to turn ideas into reality. Joe is a highly skilled plumber and electrician too which is hugely advantageous. He is professional and easy to have in your home. I can’t recommend Joe highly enough.
