Sun tunnels are an affordable and energy-efficient way to brighten internal spaces where traditional windows or rooflights are not suitable.
What Is a Sun Tunnel?
A sun tunnel (sometimes called a daylight tube or solar tube) captures sunlight from your roof and channels it through a reflective tube into your home. They are perfect for hallways, stairwells, landings, loft conversions, bathrooms and other rooms that lack natural light.
Professional Installation for Any Roof Type
Our network of installers can fit sun tunnels on a wide range of properties, including:
- Pitched roofs
- Flat roofs
- Slate roofs
- Concrete and clay tiles
- Dormer roofs
- Extensions and garages
Whether your home is modern or period, there is usually a solution to let natural light in with minimal disruption.
Rigid vs Flexible Sun Tunnels
There are two main types of sun tunnel installation:
Rigid Sun Tunnels
Best for maximum light output and longer runs through roof spaces. Ideal where installer access is easy.
Flexible Sun Tunnels
Suitable where the tube needs to navigate around obstacles or where loft space is limited.
A qualified installer will advise on the best option for your home.

Frequently Asked Questions
How long does sun tunnel installation take?
Most installations are completed within half a day. More complex jobs involving long rigid tubes or flat roofs may take slightly longer.
Do sun tunnels cause heat loss?
Sun tunnels are well-insulated and designed to minimise heat transfer. They typically perform better than traditional roof windows in terms of energy efficiency.
Can sun tunnels be installed in a flat roof?
Yes. There are specific flat roof sun tunnel kits available, including options from Velux and Solatube designed for EPDM, felt, GRP and asphalt roofs.
Will I need planning permission?
In most cases, sun tunnel installation does not require planning permission. Properties in conservation areas or listed buildings may need additional approval from the local authority.
