Bathroom Fitting- 27 Sep 2026
John recently installed a new bathroom and kitchen and built an understairs toilet room for us. He also did many smaller jobs including rewiring, plastering, roofing jobs. From beginning to end we were blown away by John's work. He was very fast but also never compromised the quality of the work which was always impeccable. He advised us the whole way about the best quality materials to buy and, when things went wrong (tiles not arriving on time etc), he was really helpful and gave great advice on how to deal with any problems. He was also just such a pleasure to work with! He always ensured that the area was very nice and clean after finishing a task. Would highly recommend John to family and friends (and already have done!) and I'm sure we will have him back in the future. Very reliable and trustworthy builder!

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.

Questions to ask local loft conversion companies in St Johns Wood

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 St Johns Wood?

A local loft conversion company in St Johns Wood 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 St Johns Wood 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 St Johns Wood 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 St Johns Wood

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 St Johns Wood before agreeing to start the work.

Do I need planning permission for a loft conversion in St Johns Wood?

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