I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.

Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

Handyman- 12 Oct 2018
The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

Latest review:
I received planning permission for a 3m extension, garage conversion and garden office with a toilet/shower and the architect recommended Timall. We of course carried out all our due diligence before selecting Timall as our builder. I received around 8 final quotes from various legal and reputable builders, and gratefully we chose Timall after checking their previous projects. Timall renovated my townhouse, stripped to brick, repartitioned to be more functional for my family, moved bathrooms, new kitchen etc. The council building control said we needed piling for the 3m extension, and Timall were fantastic to change their plans to carry out other internal work whilst a piling specialist was called in, who Timall also liaised with. The garden office, 3m extension and garage conversion all went well. Parminder the director was very hands-on during the project daily, with his builders on-site daily, honest in his advice, and very experienced in his knowledge of the building industry.

Restoration & Refurbishment- 28 Apr 2022
Forcim did an amazing job in renovating our London flat- it looks like a completely new property! Throughout the process Forcim was incredibly responsive, providing regular updates, and proactively keeping us informed. He provided solutions to any problems, and clearly very knowledgeable in his trade. His prices were very transparent, and although not the cheapest quote, was well worth paying the extra given the high quality of the finish on all areas of the work (e.g., tiling, plastering, painting and carpentry). On this project, although we were not in the country, Forcim went above and beyond to project manage and ensure that the flat was in impeccable condition when we returned. We would definitely use him again for any future works, and could not recommend him highly enough.

Questions to ask local loft conversion companies in Finchley

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 Finchley?

A local loft conversion company in Finchley 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 Finchley 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 Finchley 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 Finchley

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 Finchley before agreeing to start the work.

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

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