Loft Conversion- 10 Feb 2026
We had a great experience working with BS Loft Conversions on our L-shaped dormer loft conversion. Anxhelo was friendly, approachable and professional from the initial quote through to completion. We made a few changes as the build progressed, and he was always open to discussing options and finding sensible solutions. We found the original quote fair, and the additional items we added were also priced fairly. Anxhelo was generous with his time in offering advice on different aspects of the build, which we really appreciated. The team – Anxhelo, Klaidi, Henry and Jimmy – were on site consistently, worked hard, and are clearly experienced at what they do. At the end of each day, and at the end of each stage of the project, the site was always left very clean and well organised. Before choosing BS Lofts, we spoke to previous clients and heard positive feedback, which gave us confidence. Having now worked with them ourselves, we’re happy to recommend them to friends and family.

Extensions- 27 Aug 2025
Dunster House Garden Office (5m x 2.5m build) We are absolutely delighted with the garden office that Michal and Lenka built for us. From start to finish, their expertise and attention to detail shone through. They guided us with thoughtful consultation, listened carefully to our ideas, and delivered a finished office that is both beautiful and practical. Their work ethic, professionalism, and friendly approach made the whole process stress-free and enjoyable. The quality of the build is outstanding, and it’s clear they take great pride in what they do. This was a 10/10 experience, and we could not recommend them highly enough! We also used them again for another job to build install a Pantry; Michal and Lenka recently built and fitted a bespoke pantry for us using Howdens units, and we are beyond impressed. Their knowledge and craftsmanship are second to none. They made excellent recommendations throughout the process, ensuring the final result was exactly what we needed.

Loft Conversion- 6 Mar 2018
Loft conversion. We were delighted with Peter and his team. We were impressed with the hard work shown by all of the builders on site. We were particularly impressed by the speed(2 months) and quality of the work at a competitive price. There was surprisingly limited disruption to family life. Most access was from outside with toilet facilities also located outside. As with all big builds issues will occur. These issues were dealt with switly in a professional manner. We would highly recommend Peter and his team

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Questions to ask local loft conversion companies in Wimbledon

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Wimbledon?

A local loft conversion company in Wimbledon will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Wimbledon should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Wimbledon loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Wimbledon

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Wimbledon before agreeing to start the work.

Do I need planning permission for a loft conversion in Wimbledon?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Wimbledon loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Wimbledon loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
