What should I expect from a loft conversion company?

A specialist loft conversion company will handle the process from design through to completion. This includes providing detailed plans, dealing with planning permission or permitted development checks, ensuring structural safety (including joist strengthening and fire safety compliance), and managing all trades involved. You should expect transparent pricing, a clear schedule, and full adherence to Building Regulations.

Do loft conversion companies need insurance?

Yes. They should hold public liability insurance to cover property damage or injury, and employer’s liability insurance if they have a team. Companies offering design or structural services should also have professional indemnity insurance.

What questions should I ask before hiring a loft conversion company?

Ask whether they’ve completed similar conversions in properties like yours especially if it’s an older or listed building. Check who will manage planning applications and building control, what their typical timelines are, and whether they offer a fixed or itemised quote. It’s also useful to confirm how they handle unforeseen costs, subcontractors, and any aftercare once the project is complete.

Do I need planning permission for a loft conversion?

Not always. Many loft conversions fall under permitted development rights, especially dormer and rooflight-style conversions, provided they meet specific volume and set-back rules. However, if your home is in a conservation area, or you’re altering the roofline significantly, planning permission is usually required. A good company will guide you through the permissions process from start to finish.

How long does a loft conversion usually take?

The timeline of your loft conversion will vary lots depending on the size and type of conversion. A straightforward Velux or rooflight loft conversion can take around 4 - 6 weeks, while a dormer or mansard conversion may take 8 - 10 weeks or more. A loft conversion company should provide a clear schedule tailored to your design and property.

Restoration & Refurbishment- 28 Aug 2018
We had the very intricate loft reconfiguration done with extra big size window installation and full refurb on our recently bought Victorian end of terrace. It was a great experience all along, starting from the quantity surveyor detail level quote provision to the sign off and snagging. I was pleasantly surprised by the attention to detail with what Lux Construction delivered the works, and project manager Jonas professionalism was exceptionally high from my personal experience. Upon such a great experience I have been recommending you to all our neighbours when being asked who did such a perfect job for us. Thank you once again.

I have had my garage converted into a play room for my work. Dan, and everyone who worked with him, made the whole experience very easy and enjoyable as they were all friendly, considerate and good fun, especially for someone who hadn't got a clue about the whole process! His work ethic is admirable and shows in the end result, which is so much better than I had hoped for! I will definitely recommend Dan to friends and have already asked him to complete more work for me.

Bathroom Fitting- 15 Jun 2018
Dave is a very professional and pleasant to deal with. Came out and quoted for the job very quickly and was able to work around my timescales for the job. Totally transformed my grubby old downstairs WC/utility into a beautiful little space. Shame I can’t post before and after pictures as my words cannot give credit to its transformation. Very pleased with the job and would definitely use Dave again for other jobs and I have a long list.... !!

Carpentry- 29 Apr 2018
The whole experience with Toby was fantastic. He was professional when he arrived for the quote and the way he advised us on a solution. The reason why I selected T.Wood Carpentry wasn't just their presentation when we met, but they way he conducted himself prior. Booking an appointment along with text/email reminders, also the way the quote was sent to us. It wasn't just a standard email it will cost x,y,z. It was a business email response along with an attached professional looking quote detailing the work to be done - as well as the cost of options of splitting the job if we wanted to. The cost also included a breakdown of labour and material charges. On the day, Toby and his team arrived promptly at 8am and worked solidly until 3pm! You can't fault how hard Toby works! One thing that stood out to me was also good use of H&S when floorboards were being cut outside, so many times you see tradesman cutting corners! When the job was complete, they tidied up and hovered (even the stairs carpet which was being taken up that afternoon!) The workman ship was fantastic, honestly I will not hesitate in using Toby again for my carpentry needs. It was reassuring that Toby said, if there were any problems he would come back round - even though he said there shouldn't be any now! The invoice arrived promptly, and again this was professional. It was clearly broken down, along with clear proof of purchase for additional insulation! Thank you Toby for sorting the squeaky floorboards out!

Handyman- 28 Mar 2018
Steve came to us, after my girlfriend posted a job asking for someone to paint and decorate our 2 bedroom house, so that we could put it up for sale later that week. We had a few quotes, but Steve's was the most realistic, considering our modest budget and limited timescale. Steve and his team were always on time, very conscientious and incredibly industrious. They were there for 3 days, from 9 to 5 and worked non stop to get the job done. In this time he managed to paint the walls and woodwork in every room, fill and sand cracks, replace and fit 4 doors, fit 7 sets of door handles, 2 window handles, replace a bath panel and lay 20 sqm of laminate flooring throughout our ground floor. When they finished, the house was transformed. We had carpet laid the following day and the estate agent took pictures not long after. Within less than a week of our home being listed, we received an offer. This would not have been possible without the work Steve and the boys did so quickly and so well. So we would happily hire Steve again for all our painting and decorating needs. He's punctual, friendly, hard working and reasonable when it comes to costing. Highly recommend.
