Loft Conversion Company: How to Choose the Right One

Picking a loft conversion company is one of the biggest decisions you’ll make on your home – and most people only do it once. The right choice gives you a bigger, better home with none of the drama. The wrong one means months of on-site disruption, a price that creeps, and a result that never quite matches the brochure. This page is here to help you choose well, whoever you go with.

Not all loft conversions are the same

Most loft conversion companies work inside your existing roof – adding dormers or rooflights to the space that’s already up there, usually with sloping ceilings that eat into the usable room. Moduloft does something fundamentally different. We remove your old roof entirely and add a full new floor with a brand-new roof, built off-site in our North Yorkshire workshop and craned into place. You get full-height rooms, genuine extra bedrooms and bathrooms, and a new weathertight roof on your home as part of the work.

That difference matters for value. Independent research by Nationwide Building Society found that adding a bedroom and bathroom in the roof can raise a home’s value by up to 24% – and Nationwide’s own finding is that it’s additional bedrooms, not just floor space, that drive the uplift. A full new floor delivers exactly that.

The single most important question to ask any loft conversion company: is the price fixed, and what exactly is included? Vague quotes are where budgets go wrong.

Why homeowners choose Moduloft

We’re a specialist, not a general builder who also does lofts. Since 2015 we’ve delivered more than 355 lofts and rooftop extensions from our dedicated factory, using our patented system – the only protected pitched-roof construction system of its kind in the UK and Europe. Because your new floor is built indoors by the same team every time, quality is consistent and the weather can’t derail your programme.

We’ve seen the value first-hand. On one Cambridgeshire home, we built a full new floor and roof – insulated, plastered, windows in, heating and electrics connected – for around £150,000. That home is now on the market, and based on local property values the space we added is worth an estimated £378,000. Even allowing for the owner’s own finishing and years of market growth, the message is clear: the money you invest in a Moduloft comes back by the time your home is finished.

What’s included – and what’s yours to finish

We hand over a near-complete, weathertight, plastered new floor: the new structure and roof, all insulation, plastered walls, windows, external cladding and guttering, first-fix plumbing, connected electrics and heating, and the staircase. You add only the finishing that makes it personal – decoration, your choice of flooring, and bathrooms designed to match the rest of your home. No hidden “extras” mid-build, because it’s all agreed up front.

Planning is part of the service

You don’t need to have planning in place before you talk to us. We prepare the drawings, submit the application, and guide you through the process from start to finish – so choosing Moduloft means one company handling the whole journey, not a chain of separate trades to coordinate.

“Would never do a traditional loft conversion again.”
From planning to completion the whole experience was professional and well planned, design stage excellent really understood what we wanted to achieve and delivered a truly exceptional quality product, team on-site absolutely made the journey complete, would never do a traditional loft conversion again

Don McVinnie · Google – 2026

“They were really great to work with from design through to completion.”
We had an excellent experience with Moduloft. They were really great to work with from design through to completion. There are many advantages using their services. First and foremost is the speed. Without dependency on the weather means there are few interruptions to your build, which in Scotland is a massive bonus. Second is the ability to stay at your house for the duration of the build meaning you save on rental costs, and you don’t have to move out and back in, which could otherwise be a painful experience with children in tow. Another major benefit of that you are largely working with one single contractor with Moduloft. They provide all the services under one roof, and so can schedule all of the activities to occur in quick succession. All in all I can’t recommend the company enough. We are delighted with the quality of the worksmanship and our building inspector even remarked on the speed and quality.

Stephen Flower · Google – 2023

“Loft conversion completed with only 2-3 weeks of disruption – ModuLoft make miracles happen.”
ModuLoft provided a smooth and professional service from start to finish. Andrew’s design met the brief and the installation team were efficient, effective and on schedule. Tim the MD was communicative throughout and any small issues were dealt with a no-quibble attitude. I cannot recommend this company enough.

David Nicholson · Google – 2022

“Hard to tell from the ground floor that work was being carried out upstairs.”
ModuLoft have done an amazing job with our loft conversion. We now have a master bedroom and en-suite with a balcony view from a Velux MK19. Jim & Charlie were superb – we can’t praise them enough for all their hard work. They even hoovered up at the end of each day.

Steven Payne · Google – 2016

“Expectations were smashed – install teams have to be seen to be believed.”
Team would be on site at 8AM Monday morning, having driven 5 hours from North Yorkshire to us, and worked through to 8-9 at night. Professional and flexible throughout – last minute changes accommodated. After-sales and snagging support was exemplary. Great to see a British company really excelling at what they do.
