Latest review:
Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Loft Conversion- 10 Nov 2016
Paul and his team were able to complete the work within the 6-8 week timescale. They were efficient, clean and overall very pleasant to work with. This was our first renovation project so I was really nervous given all the horror stories you hear about builders but Paul was superb to work with. He kept us in the loop throughout the build and if there were any issues he made sure they were dealt with them without troubling us too much. The quality of their work is outstanding and we are so pleased with the turnout. We had a few add ons to the job which Paul accommodated and nothing seem too much for him and his team. He is highly recommended and we will be calling him to come back and do further work on our house.

Conversions - General- 24 Apr 2026
I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!

Loft Conversion- 1 Apr 2022
What can i say, great guys to work with. Came round and quoted as planned. Good competitive pricing. Completed the job better than planned. Always advised and tried to improve on the plans, really have good attention to detail and take so much pride in their work. Job completed bang on time. Never had a issue whatsoever. Arrived on time, good communication and nothing was to much for them. Will definitely be doing my extension next. New to my builder so they dont have much reviews, but not to worry just have a look at their instagram which they update DAILY. You can literally watch them building.. Thanks lads

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

Questions to ask local loft conversion companies in Blackheath

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 Blackheath?

A local loft conversion company in Blackheath 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 Blackheath 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 Blackheath 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 Blackheath

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 Blackheath before agreeing to start the work.

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

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