Sun tunnels & tubular skylights for Chesham: the essentials
Our sun tunnels & tubular skylights service in Chesham 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
We work across Buckinghamshire, including Chesham, and in neighbouring towns such as Amersham and Berkhamsted. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Chesham
- Pitched or flat-roof flashings
- Insulated tube sections
- Diffusers in several sizes
- Integrated electric light
- Rigid (brighter) or flexible tubes
- Daylight where no window is possible
- Small ceiling opening, quick fit
Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation
- Not a substitute for a habitable-room window
Consents for sun tunnels & tubular skylights in Chesham
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.
