    Conversions - General-
    Quoted £500 to remove small kitchen wall (<1m wide), make adjacent wall good, and move light switch. Removed wall, moved switch, and kindly moved fridge. Said he'd return to make wall good. On two occasions I arranged to WFH and he failed to show up or let me know. On multiple occasions he said he might be able to do a day but then didn't confirm. He did come by when we weren't in one day to drop wood off to cover wall gaps. One day I arranged for our dog walker to be in at 1. She waited until 3. I messaged Daniel later to ask what happened. He apparently came at 1.20 and waited for 15 mins. I believe he turned up and our dog walker didn't hear door but it's unlikely he tried to knock multiple times over 15 mins, as she was listening for him. Agreed he would finish work in new year. In Jan again failed to confirm days/times on multiple occasions. Finally agreed noon on a Sat. Failed to show up/respond to messages. Eventually got through to him - said his phone was broken. No explanation re why he didn't show up. Agreed he'd come the next Sat but no show again. No response to message or to later one asking if he planned to finish the job. Received a missed call but nothing further. I've left it a month as hoped he would get in contact. It's clear he has run off with £500, leaving giant holes in wall. I work long hours and weekends are precious. I have no patience for someone who has no respect for my free time, or for fact it's not possible to WFH all the time.

Questions to ask local loft conversion companies in Twickenham

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 Twickenham?

A local loft conversion company in Twickenham 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 Twickenham 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 Twickenham 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 Twickenham

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 Twickenham before agreeing to start the work.

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

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