Sun tunnels & tubular skylights in Sudbury: what is involved?
For Sudbury homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Jobs in Sudbury 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
- Integrated electric light
- Pitched or flat-roof flashings
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Insulated tube sections
- Daylight where no window is possible
- Optional ventilation or lighting kit on some models
Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation
- Light output falls with tube length and bends
Planning, building control and Sudbury
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. 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.
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. 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.

Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.

Can it work at night?
Some models include a light fitting in the diffuser.
How do I book a survey in Sudbury?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Sudbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
