Sun tunnels & tubular skylights for Berkhamsted: the essentials
For Berkhamsted 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Berkhamsted, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
From Berkhamsted to Chesham, Hemel Hempstead and Amersham, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Rigid (brighter) or flexible tubes
- Integrated electric light
- Pitched or flat-roof flashings
- Insulated tube sections
- Diffusers in several sizes
- 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
Do you need permission in Berkhamsted?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Some models include a light fitting in the diffuser.

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.
