I needed someone to lay LVT flooring in my hallway and cloakroom. Kev contacted me almost immediately and visited the next day to assess the job. He offered a very reasonable price and the work was outstanding. I’m thrilled with my flooring and Kev’s attention to detail was impeccable. I’ll definitely use him again for my other rooms.

Frazer completed our loft conversation for us and we cannot recommend him highly enough. Nothing was ever too much trouble and his skill-base in what he does is very impressive. The work he carried out for us in the end ranged from a loft conversion with en-suite to the removal of two walls on ground and first floor and even re-laying solid oak flooring throughout our ground floor for us too. Not only did he do the work above but he helped us achieve our dream space by being so amenable to our requests to make adjustments as we went along, even creating a bespoke crafted skirting board so that we could have our picture window at the height we wanted. In addition he designed and created beautiful fitted wardrobes into our eaves space and wooden windowsills through-out using wood we had sourced and wanted to use. Throughout the work he was always professional, considerate and communicated continually with us around what we were wanting. He stayed with us the entire time, focused on getting our job completed rather than jumping onto other jobs and he worked so hard every day, always available throughout the work taking place if we needed to check anything. What we appreciated the most from Frazer was how regularly he communicated with us about what was coming up so that we could make the decisions we wanted to make along the way, without feeling as though changes were being made outside of our preferences. The work being done was made to feel very easy from our side where Frazer is so experienced and self-directed, arriving promptly every morning and working hard all day whilst always being open to talking anything through whenever we wanted which was so reassuring for us. Frazer is professional and warm as an individual and we were really grateful for how he communicated and liaised so politely and considerately with our neighbours throughout the work. He is always happy to be guided by his customer which we found a huge benefit as we often had our own ideas of what we wanted but when we encountered problems we found him to be very creative and he often found solutions to problems that we hadn’t thought of. He suggested using the dead space we had in our en-suite to create a tiled recessed space for our toiletries and also suggested adapting another dead space in the bedroom by making a hidden shelving space which has been invaluable to us as we work from home. Frazer’s work ethic is instantly evident and by working as hard as he did every day it meant that he finished the job ahead of schedule which we were so grateful for. We are utterly delighted with the work he has done for us and we have requested him back since to do some additional smaller jobs. As someone who is extremely reliable and skilled, we wouldn’t hesitate to recommend him to anyone needing work done.

Questions to ask local loft conversion companies in Brighton

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 Brighton?

A local loft conversion company in Brighton 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 Brighton 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 Brighton 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 Brighton

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 Brighton before agreeing to start the work.

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

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