Sun tunnels & tubular skylights in Sevenoaks: what is involved?
Our sun tunnels & tubular skylights service in Sevenoaks 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
Jobs in Sevenoaks are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Insulated tube sections
- Integrated electric light
- Ventilation adaptor
- Small ceiling opening, quick fit
- Low maintenance
Before you order: points to check
- Gives light, not a view
- Not a substitute for a habitable-room window
Planning, building control and Sevenoaks
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Sevenoaks: questions
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
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.
Will I need planning permission in Sevenoaks?
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.
Do I need to be at home for the survey in Sevenoaks?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
