Great experience with Aziz and team. They provide lots of advice and a detailed quote before starting any works. The work was quick and efficient and they were super tidy throughout the whole process. All works were completed to a high standard and we are so happy with our newly installed radiators. Thanks again for the amazing effort

Shame is fantastic, a rare find. I’d use him for anything I do going forwards if he has capacity. Finally got my dream kitchen, hand made with bespoke solid wood cabinets, start to finish in 2 weeks. Delighted!
