We employed Nicky to install our kitchen, splashback and worktops. Nicky and his brother Liam were punctual, polite, tidy and most importantly their work was excellent. Having mentioned we were after a media unit in the front room, Nicky suggested they could make something bespoke for us and we trusted them to do it and what a fantastic job they did. We would highly recommend Nicky as the work they have done is nothing short of fantastic!

From start to finish, Paul and the team were superb; we are so happy with the finished product and the workmanship is brilliant. In particular, Paul was always available on the phone and the communication throughout the build was great. The guys on site were always polite and tided up everyday which was good as we have small children. We would thoroughly recommend Paul and his services again

Restoration & Refurbishment- 27 Aug 2026
Charlie and his team took two rooms back to brick and rebuilt them from scratch: new floor, plastering, ceiling and coving. Fantastic job throughout. Great workmanship, good communication, and they kept the site clean and tidy. They started promptly on the day agreed and finished within the timeline they’d quoted. Would happily recommend them and hope to use them again on future projects. Thank you!

Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.

Bricklaying- 23 Mar 2022
Very friendly and polite team. James and Lewis did a fantastic job rebuilding my boundary wall. Both had a high level of experience within the building trade. The wall was rebuilt to match the existing wall with great skill. Minimal mess was made during the work and everything was cleaned up after work was completed. I would highly recommend them and use them again.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Handyman- 23 Jun 2025
Extremely Disappointed – AVOID This was honestly one of the worst experiences I've had with a company. Communication was non-existent throughout the project. They would show up for a couple of hours, then disappear for the rest of the week, despite having agreed to a 7–10 day timeline. The job dragged on for nearly a month, causing delays and costing us money. When the work was finally “completed,” they had failed to connect the water properly — both the bathroom and kitchen sinks were leaking. We had to bring in professional builders to fix their mistakes, which incurred even more costs. If you're in the property business, I strongly advise against working with this company. They offer constant excuses, drag out timelines, and clearly lack the experience required for proper home refurbishments. Their workmanship on kitchens and bathrooms is especially poor — what should have been a straightforward job turned into a £6,000 mistake. Do yourself a favour and hire professionals from

Rez and the Team have done an excellent job with the complete bathroom renovation and additional decorating works, laminate flooring in the hall and living room, along with plumbing and electric tasks. Very professional, with great communication and finished all works to a high standard within the estimated time, accommodating all changes as the works went.
