Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.

Restoration & Refurbishment- 6 Oct 2025
Rich and the team have done a fantastic job completing my kitchen and hallway renovation. His team guided me the whole process and were great communicators. No problem was too big or small to handle. There were some issues through the job (due to the initial poor design of the kitchen when it was first built) but the team were quick to resolve this professionally. I would not hesitate for a second to recommend Lux Contracts. Next year, I will be booking them for the rest of the flat! I’m happy to be contacted by prospective customers if any further information is needed. Rhys Gallagher

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Extensions- 21 Jan 2023
I’m a bit late adding this review but Vasile just reminded me. We are really happy with the home that Vasile built for us. It’s a Victorian terrace over 3 floors that needed a full renovation including electrical re-wiring, new plumbing etc plus a gf side and rear extension plus a loft conversion. Vasile and his team worked really hard to get us the finish we wanted. He always was on-hand to solve problems from building control to water pressure. He was always very friendly to work with and extremely respectful. We always got the impression that he wants to make his customers happy and takes pride in his work. Because of Covid and issues with materials and the labour market, our job took longer than expected but I think this was really outside of anyone’s control. We now have a really beautiful house that we love living in and it’s in no small part thanks to Vasile. I have recommended Vasile to friends already and have shown some of his potential customers round our house. They were always really impressed and inspired.

Loft Conversion- 1 Apr 2022
What can i say, great guys to work with. Came round and quoted as planned. Good competitive pricing. Completed the job better than planned. Always advised and tried to improve on the plans, really have good attention to detail and take so much pride in their work. Job completed bang on time. Never had a issue whatsoever. Arrived on time, good communication and nothing was to much for them. Will definitely be doing my extension next. New to my builder so they dont have much reviews, but not to worry just have a look at their instagram which they update DAILY. You can literally watch them building.. Thanks lads

Extensions- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

Conservatories- 21 May 2026
Rude. Standards of the extension were poor. The roof leaked. Gavin was fast to fix it, however it then leaked again. The patio doors didn't close properly. I lost confidence with Gaven so had an additional trades person to rectify the issues at extra expense to myself.

Loft Conversion- 23 Apr 2019
A very positive experience. We are not going to say everything was plain sailing. We got there in the end. Arick & Greg, the joiners were especially brilliant. Office communication could be improved at times and the office could be more pro-active. All of the others Duanne, Wesley and Rocky were great. There are a few things ourselves we have to do but now have a extra room in which to live and work. The guys put in long hours and put up with interruptions from our three dogs. Arick & Greg work incredibly hard and put in long hours ; much more then perhaps anyone else we have seen. It is always difficult dealing with things at a distance and we appreciate the office sorting things out when minor issues have arisen (we know they have changed some of their procedures because of us!). Overall it has been a very positive experience. Just glad that soon things will be completely finished and our new floor will no longer be like a building site. We believe we have added value to our house with the help of econoloft and our looking forward to moving in soon.

Questions to ask local loft conversion companies in Bromley

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 Bromley?

A local loft conversion company in Bromley 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 Bromley 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 Bromley 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 Bromley

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 Bromley before agreeing to start the work.

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

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