Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.

Fantastic job from start to finish! They laid the turf, fitted the sleepers, and levelled the ground to a really high standard. The attention to detail and workmanship were excellent, and they left everything clean and tidy when they finished. They were reliable, hardworking, and kept me informed throughout the job. The finished garden looks amazing, and I couldn’t be happier with the result. I would highly recommend them to anyone looking for quality landscaping work.

Conversions - General- 23 Jul 2025
I recently had the pleasure of working with Teimo and his team on a full renovation of a probate house, and I couldn't be happier with the results. The entire house needed a complete overhaul, including two new bathrooms, a kitchen extension, new doors, skirting, walls, plumbing, electrics, as well as front garden paving, a brick wall, and back garden fencing. The quality of the work is outstanding. Teimo and his team take immense pride in everything they do, and it really shows in the final product. They are not only highly skilled but also incredibly polite and tidy, ensuring the worksite remained clean throughout. They worked hard, from 8:30 AM to 5:30 PM every day, and completed the project on time without any issues. What truly stands out about Teimo is his honesty and clear communication. He’s upfront about everything, and you can trust that the price you’re quoted is the price you’ll pay—there are no surprise cost increases along the way I highly recommend Teimo and his team

Shumon and his team did plastering, painting and decorating and they built me a fireplace and fitted in a fire. I would highly recommend him - he is absolutely brilliant and did a great job - they take a lot of pride in what they do, very trustworthy, and I am looking to have them back about Christmas time to do some bathroom work. They are very good value for money.

Alex and the guys did a brilliant job from beginning till end. They were so helpful in getting a quote and advice on how to best proceed. I also got a clear upfront quote before work started. They did the job exactly as discussed and in the time expected, and it looks really nice. They're also really nice people, tidy and considerate and just no hassle at all. I'll definitely hire them again for any future work. It was only a days' work, and the whole job was finished in less than a week from when I posted the ad. I really can't think of anything negative to say at all.

Bathroom Fitting- 20 May 2026
Saba and Zura were outstanding and an absolute joy to work with on this project. I initially hired them to fit my new bathroom, and I was so impressed with the quality of their work, that I asked them to complete the rest of my renovations, which included new flooring, decorating, installing wall panels and fitting a new kitchen. All of it were completed to the highest standards and ahead of schedule.They are very professional, friendly, hard working and communicates so well. This is my third project, and by far the most stress free one, I couldn't recommend them enough! Thank you guys
