Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Haxhi and his team exceed my expectations. We did agree on a bathroom renovation which basically everything was done from scratch. He was always on time and he met the deadline of the project. I had an issue with my water pump but he managed to fix it for little cost. Also he did the tiles for me on the wall and floor with very minimum waste and he did a brilliant job. We changed the position of the basin in order to save space and we did replace it the washing machine(hidden). We are now working on my other property to renovate the bathroom. Hahxi is very professional, knows the job very well, he did coordinate with me on every step to make sure we are on the same page . I strongly recommend him for any renovation project you may have.

We used Cubitt Wren for a full interior renovation earlier this year while we were away over the Easter period, and I honestly could not be more pleased with how everything turned out. They took on the lot, a brand new kitchen, a bathroom en suite, and a full repaint throughout the house. What really stood out to me was how smoothly the whole thing ran from start to finish. Whenever my input was needed on design choices or finishes, I heard back quickly by email and everything was explained clearly. I never felt kept in the dark, which as someone who wasn’t on site made a real difference. Coming home to the finished result was just lovely. The whole place felt fresh and beautifully done, and it was a joy to walk back into. I would highly recommend Cubitt Wren to anyone looking for quality renovation work. You also get a dedicated project manager who keeps you updated throughout, which is such a reassurance when works of this scale are going on. A wonderful experience from beginning to end.

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.

After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Gas Work- 26 Oct 2025
I was able to get my own boiler and just pay for the extra material and installation. Not all traders accept this. The price was very competitive. I was sceptical at the start but was reassuring on how quickly the job was completed. There was an issue with the thermostat but was sorted out the following week. The gas certificate, building compliance and boiler registration was completed promptly. Would definitely recommend, please allow Shami to quote before making a decision, you won't be disappointed.

Questions to ask local loft conversion companies in Upper Holloway

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 Upper Holloway?

A local loft conversion company in Upper Holloway 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 Upper Holloway 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 Upper Holloway 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 Upper Holloway

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 Upper Holloway before agreeing to start the work.

Do I need planning permission for a loft conversion in Upper Holloway?

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