What do sun tunnels & tubular skylights in Cricklewood involve?
Our sun tunnels & tubular skylights service in Cricklewood 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Cricklewood, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
We work across Greater London, including Cricklewood, and in neighbouring towns such as Kilburn and Hampstead. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Ventilation adaptor
- Integrated electric light
- Pitched or flat-roof flashings
- Optional ventilation or lighting kit on some models
- Daylight where no window is possible
Before you order: points to check
- Not a substitute for a habitable-room window
- Light output falls with tube length and bends
Planning and building rules for Cricklewood
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sun tunnels & tubular skylights in Cricklewood
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
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.
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.
Can you work alongside my builder in Cricklewood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Cricklewood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
