Public evidence profile
How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.
Each card sums up one thing we can check from public sources. Open it for the full detail and the named source. This is evidence context, not a guarantee.

“Major extension/renovation projects present challenges known and unknown and it’s essential to have a builder who you can trust to be reliable, realistically priced, helpful with ideas and who will stick to timelines. South London Conversions were all of these and Tomasz Slembarski was an excellent project manager. He was always contactable throughout our six month project and his team, many of whom were long term employees, were very highly skilled and hard working. We are extremely pleased with the outcome and we have no hesitation in recommending SLC.”
“Tomas and his team are excellent builders and delivered an outstanding response to all our requests for our modern kitchen extension. They were polite, well spoken, good humoured, and showed great attention to all the details as well as the big scary stuff with a cranked steel supporting our 'floating bedroom'. The work proceeded to schedule even with all the precautions of Covid lockdowns. Tomas' team's skills and focus on their work was admirable and we would have no reservations in recommending them for your project.”
“The work was excellent and what was really reassuring was that the same people who started the job, finished it and they were there every day and not taken off the job. The standard was extremely high and after reading all of the very worrying stories about other builders , it was in fact the best work that I have had done in my house even though I have been there 20 years.”
