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.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Carpentry- 29 Jan 2026
I contacted Ekland and his brother Bes for some light refurbishment. I was so impressed with the work and speed that they ended up doing all the works I intended to do. Starting with latex screed, flooring using LVT system, architraves and skirting boards, installation of 9x heavy duty fire doors, carpets in 2x bedrooms and finally decoration. Prices were very reasonable considering the time and effort they put into installation but not only that, as I am a first time buyer they advised me on design as I didn’t really know where to start. They are honest and reliable, where I tried to save money they said it was not the right thing to do and took additional hours to make something right without a hidden extra. They turn up at 8am everyday and so easy to work with, I left them the keys to my flat and I didn’t need to check in on them at all. If you are thinking to do any refurbishment and are either hesitant or not knowing where to start these are your guys. 5* to Vukaj and thank you!

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

What to ask a Horley extension builder before hiring?

What qualifications and experience do you have as an extension builder in Horley?

An extension builder in Horley should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Horley extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Horley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Horley extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Horley extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
