How we approach sun tunnels & tubular skylights in Diss
Sun tunnels & tubular skylights in Diss means light pipes that bring daylight to halls and bathrooms with no window. We cover the IP22 district and the rest of Norfolk, with a survey before any price is fixed.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
We work across Norfolk, including Diss, and in neighbouring towns such as Wymondham and Stowmarket. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Ventilation adaptor
- Pitched or flat-roof flashings
- Rigid (brighter) or flexible tubes
- Insulated tube sections
- Integrated electric light
- Daylight where no window is possible
- Rigid or flexible tubes for awkward lofts
Things we check at survey
- Light output falls with tube length and bends
- Not a substitute for a habitable-room window
Planning, building control and Diss
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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.
Do I need to be at home for the survey in Diss?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Diss?
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.
