Acelux did a brilliant job on our office refurb. We were very happy with the work completed as well as the service. They were able to come out of office hours during the bank holiday weekend, finish on time, and even stopped back in on Tuesday to make sure we were all happy with the works.

Extensions- 21 Jan 2023
I’m a bit late adding this review but Vasile just reminded me. We are really happy with the home that Vasile built for us. It’s a Victorian terrace over 3 floors that needed a full renovation including electrical re-wiring, new plumbing etc plus a gf side and rear extension plus a loft conversion. Vasile and his team worked really hard to get us the finish we wanted. He always was on-hand to solve problems from building control to water pressure. He was always very friendly to work with and extremely respectful. We always got the impression that he wants to make his customers happy and takes pride in his work. Because of Covid and issues with materials and the labour market, our job took longer than expected but I think this was really outside of anyone’s control. We now have a really beautiful house that we love living in and it’s in no small part thanks to Vasile. I have recommended Vasile to friends already and have shown some of his potential customers round our house. They were always really impressed and inspired.

Chris completed the works at my house in June 2024, the works included: - removal of internal walls to make open plan downstairs - new kitchen - new WC - flooring - decorating - plumbing - electrics - bespoke joinery He was great to work this and completed the project to a very high standard. He attended site every day over a 4 week period and was committed to complete the job on time. I would recommend Chris and his team to others.

Joe was professional and responsive for my posted job to do fencing and wood trim repairs. He was able to provide a quote quickly and did the work in quick fashion. I wasn't quite sure what was feasible, but Joe was able to provide good guidance on what could be done for the repairs. The quality of the workmanship seems to be high, and I am pleased with the result. I would definitely recommend Joe for this type of work.

Extensions- 3 Jun 2025
From start to finish, Connor, Andrew and their team at Biggin Renovations Group Ltd provided exceptional service. We had a double storey side extension and garage connection to the house that included 2 new bedrooms and an en-suite completed. The team confirmed a 12 week timescale, and a week by week expectation of work to be completed, along with the payment plan which was all confirmed via contract. They stuck to their time schedules and completed on time. The price was within our budget. Along with Connor and Andrew, their team of subcontractors were very kind, helpful, polite and professional in the way they presented themselves. Very happy with the work that was completed, we will call them for our planned single storey extension in the near future. Highly recommend them.

Tiling- 24 May 2026
I cannot recommend John from Pacho Create Ltd highly enough. I'm a very particular client with high standards, I was impressed by his care, patience, and professionalism throughout. He clearly takes pride in delivering quality work and paid close attention to every detail. Living in a small flat, I was concerned about dust, but John proactively created a solution to minimise disruption, which I really appreciated. He also gave excellent advice on budget-friendly waterproofing products. We had a challenge with large-format tiles, but John worked closely with me to plan the layout, ensuring a natural, balanced finish. The workmanship is outstanding – minimal wastage, precise alignment, and superb attention to detail. I wouldn’t hesitate to use John again, in fact, I’m already planning to have him back to tile around my bath in the near future. I highly recommend him to anyone looking for a skilled, reliable professional.

Ivan and his team completed a full loft conversion at our terraced house, and we couldn’t recommend them more highly. They did a fantastic job from start to finish and were a pleasure to work with. Communication and project management throughout the project was excellent, and their commitment really showed. Nothing was ever too much trouble to ask. The project was completed within the estimated timeframe, which was especially appreciated as it finished just before Christmas. The team was very considerate while working in our home, and we stayed in the house for the entire duration of the project with minimal disruption. In addition to the loft conversion, they also replaced all our doors with fire doors and installed new flooring throughout the house, all to a very high standard. We’re absolutely delighted with the results and would highly recommend Ivan and his team to anyone considering similar work.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy
