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.

After years of working for various companies I have decided to use my skills and knowledge to go on my own. My approach to work is always honest and hard working with only accepting the highest quality of finish no matter what the job is.

Bathroom Fitting- 1 Dec 2022
Didn't finish the job and cut communication despite paying up. Took 9 weeks to not even complete a small bathroom. We're now left with an unfinished room having paid over what was quoted.

Extensions- 21 Dec 2021
Would not recommend these to anybody. They consist of Father Tony, Gareth (GWT) son and Ted - son. They started our New Build in March this year with a finish date Mid September. The schedule was amended and another date provided of the first week of November, this was amended to the 17th of November. We requested a finish date, they didn't provide one, so we accepted that they would leave site. They have left us with lots of problems, took a deposit for Air Source Heating but did not pay it over to them. We needed the build to be completed by the latest the end of January, we have not got the second fix done yet, no interior. We would estimate there is three to four months work yet, which makes it March 2021 ( A year when 6 months was quoted). There has not been any delays due to supplies and Covid, we have had a kitchen sat on site for 3 Months in line with there latest schedule. We strongly recommend that these be given a wide birth. They have passed on comments about ourselves, making it difficult for us to access tradesmen.

Extensions- 19 Apr 2023
Avoid Phil and KPM Construction (South) Ltd like the plague. My experience with Phil was beyond the worst I’ve ever experienced with a tradesperson. I’m sure Phil will respond and attempt to place blame on me. I understand from other customers and trades he uses that they will say similar to me. The job started in July last year (was meant to be finished within a few weeks) was never finished and it was only a month ago that we finally got our money back - probably one of the lucky ones. He has caused a huge amount of stress and wasted time to us. We chased him many times and he would ignore us for weeks on end, coming up with numerous excuses of why he couldn’t do the work, including blaming us. His lack of professionalism is beyond me and we had no choice but refer him to trading standards during the process. I’m just pleased we were able to find another builder which has provided some perspective in terms of how truly awful our experience with Phil was.

Hard Flooring- 9 Aug 2022
After a month, I had worst problems than the original one and no communication on how to fix the problems that the trade person caused. Waited for 2 months and gave plenty of time for Luca to respond, but I dont think he is willing to go back and check what the problem was. I have wasted my money and now I have to deal with a bigger problem as well. Please try to avoid his services.

Conversions - General- 6 Feb 2023
Sorry this is long: our experience differs to most on here. We chose Better Living to do our side and rear extensions from start to finish. All was good until the subcontractors finished the main structures, then it all went downhill. Ben rarely answered his phone, texts, emails etc., and because they had started a bigger project elsewhere they repeatedly abandoned ours, often for weeks at a time. Even when we went on holiday, they had the complete run of the house for two weeks but did very little. Ben deliberately held up work for two weeks after receiving a stage payment a day late, having given us one day to pay after emailing an invoice. Beyond the main structural jobs their work was often sub-standard and our instructions were not followed due to poor communication between the team. Out of frustration we eventually took a lot of work off them and drafted in other tradesmen to complete the project, also doing some of the work ourselves. We have since had to have some of their heating work rectified by engineers. Not saying everything was bad, but fact is the list of problems and poorly completed jobs is too long to list here. They finished at our property over three months ago and have still not sent us the completion documents. As usual, Ben is not responding to our attempts to contact him. Despite being hospitable to their team, we feel we were treated shabbily by BL and sadly would not recommend them.

Carpentry- 22 Sep 2021
Cancelled on me late on the night before the job was supposed to start. These things happen but nice for more notice. Rescheduled work which was to replace 3 door frames and fit new doors and furniture. After a few days the doors started sticking. Informed Dion who said he wasn't in the area. I tried to be patient to allow him to pop over when in the area, but 2.5 months later he's ignoring my messages. He also hung one door on the wrong side so now i need to pay an electrician to move the light switch and pay someone to come fix his mess. I don't think he used enough fixings on the frames. Dion is a joiner in the father/son team he told me.........

Bathroom Fitting- 13 Sep 2018
Did some good work but let us down when not accepting responsibility for his failure to commission a bore hole filtration installation that did not give us clear water for 6 months. We only found out when I employed and paid Anglian water to come out to check the system and they reported that it had never worked since installation as he did not open the air valve and so there was no chance that the iron could be put into suspension so the next cylinder could filter it properly. They opened the valve and the water is 70 cleaner - I suggest to Ben he paid £115 for the Anglian visit and install one 5 micron filter at his cost so we get the clear water he promised before being awarded the contract. I have not heard from him after this reasonable compensation request for 6 months yellow water that children will not bath in, guests are concerned with and will not drink. So would not hire him again

Extensions- 2 Apr 2021
Joe was very friendly and came and gave us a quote in January - we agreed to go ahead and were very disappointed that a week before he was due to start in April he stopped replying to any messages. He has let us down at the last moment meaning there is not time to find a replacement to do the job at the required time.
