I recently hired LLC Projects Limited to refurbish my ground floor and add a new bathroom, and I couldn’t be happier with the results. From start to finish, the team was professional, reliable, and truly cared about delivering quality work. The new bathroom looks amazing, and the ground floor transformation exceeded my expectations. Communication was great throughout, and they kept everything on track and tidy. The crew was friendly, and they handled any concerns I had quickly. I’d definitely recommend LLC Projects Limited for any home improvement work—they’ve earned my trust, and I’ll be calling them again for future projects

Bathroom Fitting- 13 Oct 2026
Fantastic work – highly recommend Cre8tive Contractors Ltd! Eric was absolutely brilliant from start to finish. He took on a property that had been tenanted for eight years and was in desperate need of some TLC to transform it back into a lovely home we could move into. The work included retiling the kitchen, installing a new sink and taps, new bathroom tiles and shower, decorating throughout and fitting new wardrobes. It was quite a transformation! Eric was incredibly patient and accommodating with our changing ideas throughout the project, always calm, approachable and genuinely lovely to work with. His pricing is very reasonable, particularly given the quality of his workmanship and the care he puts into everything. It's been such a pleasure working with someone so reliable, easygoing and professional. We're absolutely delighted with the results and wouldn't hesitate to recommend him. We'll definitely be back in touch with more work when we move again! Thank you, Eric!

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!

Hired for a kitchen refit and other works including removing a wall to open kitchen out. Understood the job, and where appropriate offered helpful suggestions.

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.

I initially called Klodi to repair the kitchen stove extractor pipe, but after seeing their professionalism, I entrusted them with additional tasks, including painting the ceiling and walls in the kitchen and installing a brand new fire door. Throughout the project, they worked quickly and efficiently without compromising on quality. Their team was highly professional, friendly, and very communicative, always keeping me informed about what they were doing and explaining each step of the process clearly. I was impressed with their attention to detail and the care they took to ensure everything was perfect. The finished work transformed my kitchen, and I wouldn’t hesitate to recommend Klodi for any home improvement tasks. Their dedication to customer satisfaction truly stood out. I will definitely use them for more jobs and recommend them.

Carpentry- 1 Jul 2025
They knew exactly what to do when I sent them the requirements regarding the replacement of my door. Due to the Grenfell legislation, I was obligated by the maintenance company of my flat to change my front door to an FD30. Tony and his team were very quick to do a site visit, provide a quote and even gave me some options of which door I could choose from. The installation was very quick and the work spoke for itself. I have recommended them to other residents and would definitely recommend to anyone else.

Questions to ask local loft conversion companies in Wandsworth

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 Wandsworth?

A local loft conversion company in Wandsworth 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 Wandsworth 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 Wandsworth 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 Wandsworth

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 Wandsworth before agreeing to start the work.

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

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