Loft Conversion- 2 Jul 2016
Top finish were ultimately hired to conduct this work. There was admittedly some job creep in this project. Alan came round and discussed our intentions and suggested a possible route forward. An architect (Red Squirrel Architects) was independently retained by us to work with the Top Finish team to deliver a Dormer conversion reorganization and significant structural works for a side return extension and installation of a new kitchen (13 steels were inserted and a sewer had to be bridge over, with permission) The job was completed to a high specification, particularly given some of the problems thrown at the team when dealing with a 150yr old property. I think it's important to understand that when undertaking jobs of this scale, and if you are planning to live in the property as we did, then you are effectively living with the team you chose. To that avail- ALL of the top finish team were always considerate and a pleasure to be around and happy to fix any concerns rapidly as required. I wish Alan and his team all the best going forward and I would recommend meeting Alan and including him in your shortlist for any job - large or small.

Bathroom Fitting- 21 Apr 2026
Marcin and his team did a fantastic job on our bathroom rennovation. A very tight space and demanding request from me (difficult tiling and suite to install), Marcin and his experts gave me some great advice on how to approach the job and the quote provided was very fair for the work undertaken. I have been so impressed by the quality of the work at every step and the project stayed on time and on budget (a miracle!). All the team members were extremely polite, respectful and always on time with great work ethic. I will be using Marcin and his team for my next project no question. Thank you Marcin, Rad & Igor for all your work and kindness.

Tiling- 1 Sep 2020
**HIGHLY NOT RECOMMENDED** I have not seen such an unprofessional service provider in my entire life. His guys lack the basic skills of tiling and created a mess of my new home. Issues: 1. They spill water in my bedroom with carpet and in lobby with wooden flooring which got damage 2. Whole house was filled with tile dust, 3. the tiles were not cleaned 4. tiles waste a separate issue 5. my balcony looked like a garbage room 6. cement marks on walls, ceiling and walls needs a paint work 7. to my utter disgust they left tiles pieces in my toilet. 8. Also the tiles are so poorly installed that I think I was better off without them. I wish there was an option to upload the pictures so people could understand my pain. Upon giving him calls to see the mess created by his guys he was reluctant at 1st to come and said he is tired & cant come. On sharing pics, he decided to show up & promised to clean the mess & complete the task. But after 2 weeks of struggle his guys shows up 3 times for 2-3 hour each. But today he finally decided to quit without doing his job. Now I need to find a new Contractor to complete the work. Also, He promised that he does quality work, to start when he visited and quoted me a price and said that he would send the quotation on mybuilder and thats how it works. He sent quotation 3 days later with 65% increase in price and later negotiated to 30% higher than original

Plastering- 29 Aug 2025
I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.

Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

They worked quickly but I had to clean a lot of the shower afterwards. I'm not certain that I wasn't overcharged as I didn't get any receipts and had to buy the shower tray and glass doors myself.

Latest review:
Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

Questions to ask local loft conversion companies in Belgravia

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 Belgravia?

A local loft conversion company in Belgravia 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 Belgravia 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 Belgravia 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 Belgravia

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 Belgravia before agreeing to start the work.

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

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