Sun tunnels & tubular skylights in Derby: what is involved?
For Derby homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
We cover all of Derby and the DE1 district, and nearby Belper and Ilkeston.
Specification options
- Ventilation adaptor
- Rigid (brighter) or flexible tubes
- Integrated electric light
- Diffusers in several sizes
- Pitched or flat-roof flashings
- Low maintenance
- Small ceiling opening, quick fit
Things we check at survey
- Not a substitute for a habitable-room window
- Light output falls with tube length and bends
Planning and building rules for Derby
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Questions about sun tunnels & tubular skylights in Derby
Can it work at night?
Some models include a light fitting in the diffuser.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
