Frank was polite and punctual. Came in to assess what was required before he did the work. Confirmed the quoted price. The work was neat and tidy. You could tell that Frank took pride in his work and wanted to make sure that I was happy with it before he left. I will highly recommend Frank for future work.

Ground floor back extension, reconfiguration and full redecoration. We chose Dali, firstly through recommendations by neighbours, seeing his work first hand and feeling confident during the consultation phases of his ability to deliver. Prior to the job commencing a schedule of works and costing were clearly agreed. We were impressed with Dali's level of communication and his availability to meet with us personally. He would always return a message promptly and that continued throughout the job. Dali expertly guided us through the project and also arranged architect and structural drawings, site surveys, council applications and 3rd party wall advice. We decided to live-in during the build which is never ideal but Dali cordoned off spaces for us to live whilst allowing him to get on with the job. He set up temporary kitchen and laundry facility some 3 or 4 times for us! Now for the business end. Dali supervised the project but also allocated a Manager, Michal to be our point person and he was on site every day without fail. Both would respond to any question promptly and courteously. I learnt to keep the questions short and be more patient as the job progressed as everything was always on their agenda to be done. Teams of builders would arrive punctually by 8am and work would always start promptly. Everyone on the team had clear instructions and their industry was on show from start to finish. I could not fault them at all for their reliability and professionalism. They were all courteous, polite and respectful and would also make a point to clear up after themselves at the end of each day. On occasions I did request a deviation it was fully discussed so we could make informed decisions but nothing, no matter how small, was made to seem trivial as they were intent on delivering an unquestionable product. The job progressed sometimes at lightning pace with crews of builders coordinated daily and we hardly had a single day where someone was not in attendance. Dali would continue with a regular update by email or phone so we were always aware of progress. When problems did occur, Dali and Michal would distress those situations, find solutions quickly and sometimes you are oblivious to there even being a problem. On the few occasions they made mistakes they were not argued about but swiftly rectified ... finding someone who was honest and proud of their workmanship has been a true find. The work progressed to schedule and the end result is something we are not only thrilled about but cannot fault at all. It is a level of workmanship we have been truly delighted with. Another thing I am confident of is that if something does happen in the future Dali will respond to my call whether it be now or in a year's time. There is so much positive to be said and I would highly recommend DPS Ltd for their professionalism, reliability and workmanship so much so I have already asked them to continue on the 1st floor.

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.

Loft Conversion- 6 May 2020
We are so pleased with our dormer loft conversion. Ciprian and his team were fantastic throughout. They did everything on time, were polite, clean and professional. The standard of the work was very high and I would recommend Ciprian's building services to anyone. Communication was very effective and he went the extra mile when material supplies dried up during the lock down to be able to finish the job. I am so impressed with his skills, knowledge and dedication to the job during a difficult time and the finished conversion is even better than I could have hoped for. I will definitely contact him again for any future building/renovation work.

Restoration & Refurbishment- 16 Jan 2026
We hired UK Vion to do a refurb of the first floor and these guys were amazing. It was so easy to work with Ihor and the team from the start, Ihor clearly communicated about the challenges and plans and the work was done as we agreed. We even agreed some additional work that came up and the price was fair. The entire team was professional and curteous, they respected our property, kept the site clean, they were always respectful with us and the neighbours. It was refreshing to work with Ihor and the team. I can't recommend them highly enough.

Questions to ask local loft conversion companies in Mitcham

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 Mitcham?

A local loft conversion company in Mitcham 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 Mitcham 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 Mitcham 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 Mitcham

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 Mitcham before agreeing to start the work.

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

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 Mitcham 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 Mitcham loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
