Latest review:
Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.

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.

Bathroom Fitting- 26 Feb 2026
Worst job ever. The first day he came at 10.30am started the job left at 9pm said it would take a day & a half. The next day he said he would be here at 8.30am again he came at 10.30am & his words were I’m going to finish in 2 hours maximum. By 3pm he still hadn’t finished & I heard him speaking to someone on the phone saying that he would be there in 45 minutes.then he told me he needed a part for my job & he would be a couple of hours, he came back 4 hours later without a part.Again he was here till 9.30pm. He said he had finished. I went to look and his work was bad. I complained he said he would come back the next day. the next he said he had finished & I told him I wasn’t happy he came back the next day. He tidied up his mistakes.he shaved the bottom of the door off a bit as it wouldn’t close coz of the new tiles & he left, as he was leaving he said please give me a good review. I said I’ll tell the truth & he said but the truth isn’t good. He didn’t stick the threshold back on.

Restoration & Refurbishment- 15 Feb 2016
Pawel and his team modernised our two bedroom house from top to bottom. They installed central heating in every room, they removed our old warm air heating, made an open plan for the kitchen and living room area, installed new bathroom and kitchen units and did the tiling too, they updated our electrics and sockets and also plastered and painted the walls and fitted our wooden flooring for downstairs. The job was completed within 12 weeks. We were very happy with the modernisation, our home looks completely different and has a new modern fresh feel. We will definately be using Pawel and his team for future jobs. Thanks again Khalima

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Extensions- 8 Dec 2023
I recently had the pleasure of accepting Jagdeep on a substantial renovation project. Initially, I was a bit apprehensive as there were no existing reviews to gauge his work. However, after seeing some of his previous projects, I decided to take a leap of faith - and it turned out to be the best decision I've ever made. Jagdeep's approach to our project, which started merely as a rear extension and shower room, was nothing short of exceptional. His remarkable craftsmanship and attention to detail soon convinced me and my wife to extend the scope to a full renovation. Throughout the process, Jagdeep and his team displayed an extraordinary level of skill, professionalism, hard work as well as trust (very rare these days). No task was too challenging, and his willingness to prioritise our needs and provide thoughtful advice was truly comforting. It's rare to find a builder with such dedication and expertise. Jagdeep is undoubtedly one of the best builders I have encountered. My heartfelt thanks to Jagdeep and his team for their outstanding work. Rest assured, for any future projects, he will be the first person I call. Thank you, Jagdeep, for turning our vision into reality, which more than exceeded our expectations!

Questions to ask local loft conversion companies in The City

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 The City?

A local loft conversion company in The City 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 The City 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 The City 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 The City

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 The City before agreeing to start the work.

Do I need planning permission for a loft conversion in The City?

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