Loft Conversion- 29 Sep 2023
We met Sunny a couple of times during the quote process and he took some time to advise us what was required during the planning process, the party wall, the potential buildover agreement. His team was respectful of the house and neighbours during this rather long project (6 months, both a dormer loft and a rear extension). We had a daily plan which was followed quite accurately even with the different extras that were requested during the project. The team also took into account the access constraint issue. We had a variety of works done, outside patio, new kitchen, new flooring full rewiring, new bathrooms, new boiler etc and were satisfied with the end result. We are particularly happy about the new kitchen installation. The discussion with the private building control was smooth and we got the building control certification without any issue. The snagging at the end of the project was taken seriously and each snag was sorted out. We were not living at the house during the works and were not locally either but the daily call / whatsapp messages and pictures ensured we were kept informed at all times. We would hire them again if we have new projects in the area.

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

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.

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.

Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

Questions to ask local loft conversion companies in Deptford

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 Deptford?

A local loft conversion company in Deptford 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 Deptford 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 Deptford 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 Deptford

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 Deptford before agreeing to start the work.

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

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