Bermuda did a fantastic job from start to finish. Our dormer conversion turned out to be more complicated than originally thought but the team at Bermuda ensured everything ran smoothly and have absolutely transformed our house.

Earlier this year, I was looking for a builder to erect a side extension and was given the details of Colin Richardson. He came highly recommended by various other people. He always arrived with a smile on his face and always at the time specified. The day to day work area was always cleaned at the end or the day, leaving it nice and tidy. I am very pleased with the work both Colin and Michael did and I would recommend them ti anyone looking for building work to be done.

Undertook extensive building work - a rear and side extension, built a summer house, landscaped the garden and paved a new driveway. They are the best building company I have ever worked with. Courteous, tidy, excellent quality, considerate of our family and our neighbours. Afrim consistently gone went and beyond to ensure that my renovations were completed to a high standard and at a fast pace. I am so pleased I made the decision to let him manage the building work from start to finish as his electrician, plumber, tilers, kitchen fitters have all been fantastic. Building works can be extremely stressful but Afrim did everything to make sure it has been as smooth as possible - would highly recommend

BS Loft Conversions are reliable, honest and operate with integrity. I recommend them to anyone who is looking for some building work whether they are big or small projects. They arrive on time, work hard and leave the site clean and tidy. Anxehlo always takes the time to answer any questions we may have and talks us through the process before providing us with all the options available from repair, replacement or re-instatement. As a novice to a huge development, it was difficult to find builders you can trust but, Anxhelo made that process easier, restoring our faith in construction work.

Kitchen Fitting- 1 Jan 2023
I have to say that Tyrone who carried the work out for is very professional and commendable. He was always on time and eager to get the work done. His attention to detail is simply quite impressive. Having completed the work i was rather surprised to learn that he called back the next day only to complete a very small detail that he forgot. A small detail that was not exactly noticeable, thus leaving us with satisfactory results. I’m certainly going to recommend their services to anyone who might require their services. Many thanks 👏👏👍
