Extensions- 26 Apr 2018
Professional Polish builders (london) ltd,?this is a suitable name for this company. They built an extension and loft for me in the time standards set. They aren’t a cheap service but the professionalism of this boys goes beyond and above. I’ve seen a lot in my life and it was the third extension I designed for myself as I’m architect. It is hard to find an honest builder who will tell you the truth about what is waiting for you during the works. The job was done relatively quickly even when I changed my mind a few times and the weather this winter was cruel but Adam and Martin were always positive so do not believe any one who gives a fixed price and time - it’s impossible to do. Adam and Martin are fantastic organizers and skillful professional builders, his team are friendly,very funny and hard working guys. Open minded guys who will tell you straight on what things you can save money on and what not to. My dog has fallen in love with them. Safety and common sense is a priority to the crew. I would recommend these boys to everyone. thanks for your help and hard work!

Extensions- 31 Aug 2024
BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Handyman- 25 Jun 2026
Do not hire this individual whatever you do. He is highly unprofessional and condescending when you try to ask him any questions, he clearly doesn’t know what he is doing and just wings it. Always makes out the fault lies with wall or the part but never his lack of skill/competence. He fitted the bracket wrong way round and when I told him this he denied it until he was forced to face facts. The tv is tilting forward and he told me that’s how it supposed to be when the diagram says otherwise and it is supposed to rest flat on the wall. I now have to pay a competent person to come and fix his mistakes! I would give him 0 stars if I could! Avoid like the plague!!!

Jess painted my hall way and put laminate flooring in my lounge. He was prompt and reliable, I was impressed with the how quickly and professionally it was done, he was extremely tidy and put my sofa back so I could still access my lounge in the evenings whilst the work was going on. He was professional at all times, and even helped me with the colors, I would highly recommend him.

Conversions - General- 20 Jun 2026
My partner and I hired Alonso and Alex to undertake a full renovation of our 3-bedroom house in SE8. Having received quotes from several other contractors, the moment we met them, it was clear they were clear communicators, approachable and dedicated to their clients. We’re incredibly happy with the work they did. The scope of work was highly varied, including rectifying historical damp issues in the lower ground room, external repairs to the roof drains and chimney, installing two new bathrooms, plus all the other internal and external work you’d expect from a full renovation. All of which was completed to a very high standard! They were always open to discussing and rectifying anything we weren’t completely happy with, or problem-solving whenever unexpected issues arose (which always happens when renovating a property of this size!). The team are lovely, trustworthy people who are a genuine pleasure to have in your home. I can’t recommend them highly enough.
