How we approach sun tunnels & tubular skylights in Watford
We handle sun tunnels & tubular skylights across Hertfordshire, including Watford. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
We cover all of Watford and the WD17 district, and nearby Bushey and Rickmansworth.
What you can choose
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Ventilation adaptor
- Integrated electric light
- Insulated tube sections
- Small ceiling opening, quick fit
- Rigid or flexible tubes for awkward lofts
What to check first
- Not a substitute for a habitable-room window
- Tube runs need insulation in cold lofts to limit condensation
Planning and building rules for Watford
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. 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. 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.

More we do in Watford
Sun tunnels & tubular skylights in Watford: questions
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.
Can it work at night?
Some models include a light fitting in the diffuser.
Will I need planning permission in Watford?
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.
Can you work alongside my builder in Watford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
