Velux Loft Conversion Guide UK — 2025 Costs, Benefits & Design Tips
If you’re thinking about adding more light and space to your attic, a Velux loft conversion might be the perfect solution.
It’s one of the simplest and most cost-effective ways to transform your roof space into a comfortable living area.
In this guide, we’ll explore Velux loft conversion costs in the UK, how it compares to dormer conversions, and how to get free quotes from local professionals on SCE Marketplace.
What Is a Velux Loft Conversion?
A Velux loft conversion (also known as a rooflight conversion) installs Velux roof windows into your existing roof slope without changing its structure.
This makes it faster, cheaper, and easier to complete than dormer or mansard conversions.
It’s perfect for homes with sufficient roof height and where planning permission may not be required.
