Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

Latest review:
Based on architect recommendation, we contracted Alain on a private basis to produce structural engineering designs for our home renovation. He undertook a site visit and then produced structural designs to support a large number of elements related to new support beams, lintels etc. These have been iterated with the architect and the process has been very smooth. He was very responsive and nice to interact with. Wouldn't hesitate to recommend as a structural engineer for the type of project we undertook (loft conversion, new pitched roof, new openings within walls and ground floor open plan conversion)

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability

Questions to ask local loft conversion companies in Holloway

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 Holloway?

A local loft conversion company in Holloway 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 Holloway 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 Holloway 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 Holloway

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 Holloway before agreeing to start the work.

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

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