What do sun tunnels & tubular skylights in Keswick involve?
Our sun tunnels & tubular skylights service in Keswick covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
We work across Cumbria, including Keswick, and in neighbouring towns such as Penrith and Workington. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Rigid (brighter) or flexible tubes
- Diffusers in several sizes
- Insulated tube sections
- Pitched or flat-roof flashings
- Integrated electric light
- Optional ventilation or lighting kit on some models
- Low maintenance
Things we check at survey
- Gives light, not a view
- Light output falls with tube length and bends
Do you need permission in Keswick?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Keswick: questions
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Keswick?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
