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.

Kitchen Fitting- 24 Aug 2022
I spoke with Nathan and he seemed very positive and we arranged a day for him to come to do the job. He asked me to send some pictures of the work prior to him coming which I sent through to him but did not get a reply. I messaged a further 2 times to confirm if he was coming or not and he ignored my messages and did not come at the agreed time. I really needed this job doing quickly and waited because he was meant to come, so 1 week later I still need the job completing. Very disappointing.

Hard Flooring- 13 Feb 2015
I would like to say that Andy Daniels building services is quite simply, fantastic. His attention to detail is to be beheld. Right from the off, he was on the case. He is the one-stop shop for any building needs required. His original quote was highly professional and offered many sensible suggestions which we had not thought of. We took his advice on board and as a result have a far better outcome. He has suggested things we just would have never even thought of. The quality of his workmanship is highly impressive and he leave no stone unturned. I cannot rate this builder high enough. we changed and amended a number of things throughout the upgrade and Andy took this in his stride. I only wish I organised for Andy to do the whole project, unfortunately I originally booked a few tradesmen individually....big mistake as Andy can and will do the lot. It would have made life so much easier and I it's clear the finish would have been spot on. In summary, cracking builder who can organise everyone and quality is second to none. You have transformed our house and we all thank you!!!!

Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.
