Loft Conversion- 30 Oct 2026
Alin and his team did a fantastic job or our recent double dormer loft conversion in our flat in North London. The project was particularly difficult for access of the scaffolding, but Alin did a great job of making the whole process as smooth and stress free as possible. They were super quick doing the works and turned up on time everyday, at the agreed hour. We have 12 brand new extra large steel beams adding to the roof, new roof tiles, skylights and rear dormer cladding. Without question the best builders we've ever worked with and we would have zero issue recommending them for any job. The quality of the work is flawless. Cannot give more than 5 stars, else we would give 6 stars.

Extensions- 25 Aug 2020
I did my due diligence on Vullcan, but things went downhill. After a week i got a pre-tax invoice for £3000 for a more "complex" drainage system which was already completed, this was the start of them trying to get around contract items and look for every way possible to charge extra fees which i can’t go through in the word limit here. When that dint work they refused to do the work. e.g. they literally installed a tempered glass sheet, with liquid glue on my roof and stated to me that this was a "roof window". I had to show them buildings regulations that this was unacceptable and illegal especially when our contract said it has to be a VELUX ROOF WINDOW! Promised a 6-8 week completion, this is 9 months later. I had now paid about 90% of the original bill and 100% of additional costs. The final payment was due after completion and a 2 week snagging period. But the demand for payments started, with threats to sue. This was laughable as they hadn't completed the job. •The roof was leaking •Electrical issues with the fuse box and multiple light /electrical points •Outstanding items •The buildings controls company stated they would not be able to sign off on the building work because of outstanding issues, which I wouldn’t have even known as they lied stating they HAD the certificate. I agreed to send a FULL payment to an escrow company and pay HALF of the costs so they can complete and fix safety issues but they refused! Shameful experience.

Loft Conversion- 10 Feb 2026
We had a great experience working with BS Loft Conversions on our L-shaped dormer loft conversion. Anxhelo was friendly, approachable and professional from the initial quote through to completion. We made a few changes as the build progressed, and he was always open to discussing options and finding sensible solutions. We found the original quote fair, and the additional items we added were also priced fairly. Anxhelo was generous with his time in offering advice on different aspects of the build, which we really appreciated. The team – Anxhelo, Klaidi, Henry and Jimmy – were on site consistently, worked hard, and are clearly experienced at what they do. At the end of each day, and at the end of each stage of the project, the site was always left very clean and well organised. Before choosing BS Lofts, we spoke to previous clients and heard positive feedback, which gave us confidence. Having now worked with them ourselves, we’re happy to recommend them to friends and family.

Questions to ask local loft conversion companies in Stratford

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 Stratford?

A local loft conversion company in Stratford 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 Stratford 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 Stratford 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 Stratford

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 Stratford before agreeing to start the work.

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

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