Velux Loft Conversions in London

We design and build high-quality Rooflight and Velux loft conversions across London, helping homeowners turn underused roof space into bright, practical rooms that feel like a natural extension of the home. From design and approvals through to construction and finishing, our team can manage the entire process.

A Velux loft conversion, also known as a rooflight loft conversion, works within the existing shape of the roof rather than significantly altering its structure. Velux windows are installed into the roof slope to introduce natural light and ventilation while retaining the property’s existing roofline.

Because they involve fewer structural changes than dormer or mansard conversions, Velux loft conversions can be a straightforward way to create an additional bedroom, office, dressing room or living space where there is already sufficient headroom.

Advantages

  • Retains the existing shape and character of the roof.
  • Introduces plenty of natural light into the loft.
  • Typically involves less structural alteration than larger loft conversions.
  • Can provide a cost-effective way to make existing loft space usable.
  • Often suitable where homeowners want a more discreet external appearance.

Best suited for

  • Properties with good existing loft height and usable roof space.
  • Homeowners who want to retain the original roofline.
  • Lofts that need more natural light without a major roof extension

House Extension Types

There are several types of Velux loft conversions, each offering different looks and levels of space. Here are a few common options:

Standard Velux Loft Conversion

A standard Velux loft conversion works within the existing roof structure, adding roof windows to create a brighter and more usable internal space. It is ideal where the loft already has sufficient headroom and does not require substantial changes to the roof shape.

Multiple Velux Rooflight Conversion

Using several Velux windows across the roof can dramatically increase the amount of natural light entering the loft. This works particularly well for larger bedrooms, open-plan spaces or home offices where a brighter, more spacious feel is important.

Velux Conversion with Ensuite

A Velux loft conversion can incorporate an ensuite bathroom alongside the main bedroom or living area. Carefully positioned rooflights help bring natural light into both spaces while maintaining the existing external roof profile.

Velux Conversion with Cabrio Balcony

A Velux Cabrio system transforms from a roof window into a small balcony-style opening, creating a stronger connection with the outdoors. It can be a good option where homeowners want more light, ventilation and views without constructing a traditional roof terrace.

L-Shaped Velux Loft Conversion

An L-shaped Velux conversion makes use of both the main roof and the roof over the rear outrigger, where the property's layout allows. Rooflights can be positioned across both sections to create a larger, connected loft space while keeping structural roof alterations relatively limited.

We recently had our loft converted and are absolutely delighted with the result. From the very first meeting with Seb, who took the time to explain all the options and answer our questions, we felt confident we had chosen the right company. He was knowledgeable, professional, and never made us feel pressured at any stage.
Throughout the project, Marius was our project manager. He kept everything running smoothly, communicated clearly, and ensured the work was completed to a very high standard. Marius’s team was very good, hardworking, and clearly took pride in their work, which really showed in the final finish.
The workmanship throughout was outstanding, and the finished loft has completely transformed our home. The attention to detail, quality of finish, and professionalism shown throughout the project exceeded our expectations.
A big thank you to Seb, Marius, and the entire team for delivering such a fantastic loft conversion. We would highly recommend this company to anyone looking to add valuable space and improve their home

I initially came across Simply Easy Refurbs (SER) online and followed their work for some time before my project reached the right stage. When I was ready to proceed, they were one of three companies I invited to quote.

From the outset, SER stood out for their efficiency, professionalism and clear understanding of the brief. As part of my due diligence, I spoke with three of their previous clients, all of whom gave strong, consistent feedback. This gave me the confidence to appoint them for a full refurbishment, including a loft conversion and rear extension.

Throughout the project, SER maintained a high standard of professionalism. Communication was consistent, with regular check-ins to ensure everything remained on track and aligned with expectations.

I would not hesitate to recommend Simply Easy Refurbs to anyone considering a full home refurbishment.

Brilliant execution
We had a very good experience with Simply Easy Refurbs, the communication was always on point whether email, what's app or telephone. The dedicated what's app group is a great platform to check on the progress, share ideas visually etc. We had a good working relationship with all the team but especially with Tomas, our design was executed to a very high standard. All the works carried out was highly professional, done to a high standard and good quality materials were used. All the tradesmen involved worked exceptionally hard sometimes staying later than expected just to get the job done!
We're very happy with the end result. We have a future proof, modern design and the loft conversion has created so much space! We would highly recommend this firm for renovation projects! Thanks again to Seb, Tomas and the team.

We had a great experience with Sebastian and his team. Our mansard loft conversion has added a whole new floor to our flat and provided an amazing new bedroom for our daughter. Our builder Loren and his team were excellent - the work was done on time and to cost; any issues were swiftly dealt with. As expected, we had to get a fire sprinkler system installed - with hindsight we could have started shopping around for a company to do it before building control confirmed it would be necessary; but we were lucky - we found a company who could do it quickly and that meant there was no delay to our project. The aftercare has been fabulous - only today their electrician came back to move a fan in the new bathroom ceiling that was in the way of our new cupboard doors. We couldn’t have asked for more from SimplyEasy Refurbs: we’d recommend them 100%.
I had a very specific idea for my loft and the team made it happen. Great advice, great quality work. I had so many positive comments from friends and relatives. Also, I recently put my house on the market and viewers loved the loft, I have no doubt that the loft helped my house sell faster. Plus, you pay for what you signed for, no hidden fees, furthermore timing was again to what was agreed! I would have no hesitation to recommend SimplyEasy Refurbs!

Velux Loft Conversions

1. What is a Velux loft conversion?

A Velux or rooflight loft conversion converts the existing roof space without substantially changing the external shape of the roof. Roof windows are installed into the existing slopes to provide natural light, ventilation and views.

Do you need planning permission for a Velux loft conversion?

Many rooflight loft conversions can be carried out without a full planning application when they meet permitted development requirements. However, restrictions can apply to listed buildings, conservation areas and certain properties, so the requirements should always be checked before work begins.

How much does a Velux loft conversion cost in London?

The cost of a Velux loft conversion in London depends on the size of the loft, structural work required, number of roof windows and chosen internal specification. Because the existing roof shape is normally retained, it can often involve less construction work than a dormer or mansard conversion. Use our quote calculator for a project estimate.

Is my property suitable for a Velux loft conversion?

Velux loft conversions work best where the existing roof already provides enough height and floor space to create a practical room. A survey can determine whether the roof structure, headroom and layout make this type of conversion suitable.

What is the difference between a Velux and dormer loft conversion?

A Velux conversion generally retains the property’s existing roof shape and introduces windows directly into the roof slope. A dormer extends outward from the roof, creating additional floor space and headroom where the existing loft is more restricted.

How long does a Rooflight loft conversion take?

The construction period depends on the size and specification of the project, but Velux conversions are generally less structurally involved than larger roof extensions. Additional bathrooms, structural alterations and bespoke finishes can increase the overall programme.

Can a Velux loft conversion include a bedroom and bathroom?

Yes. Where the existing loft provides sufficient space and headroom, a Velux conversion can accommodate a bedroom together with an ensuite or separate bathroom, with rooflights positioned to maximise natural light throughout the new floor.
