Bathroom Fitting- 10 Oct 2026
I'm happy with the overall look of my refurbished bathroom and was satisfied with the job as a whole. The team was flexible: although they said they would stick to what was in the contract, they agreed to several changes I asked for mid-job. The project ran a little longer than originally promised, but that was because they wanted to get the quality right rather than rush. I'm quite a perfectionist, and they followed my lead on most points, though not on absolutely everything. Nodar and Kristof were both great to work with, and I'd happily hire them again for future projects.

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.

Mihail painted our hall and kitchen walls, ceilings and woodwork. He replaced a damp section of ceiling in the hall by cutting it out and fixing a new section of plasterboard, and making a seamless repair. He then sourced the leak from the bathroom shower, sourced identical wall tiles and retiled two sections around the bath. He then resealed with silicon. A plumber had previously advised us to change the entire glass screen. Mihai's repair work was exemplary and the shower is now fully watertight.

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

An extension builder in Highgate 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 Highgate 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 Highgate?

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 Highgate extension builder’s ability to deliver a result that meets your expectations.
