Sun tunnels & tubular skylights in Gerrards Cross: what is involved?
Our sun tunnels & tubular skylights service in Gerrards Cross 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
We work across Buckinghamshire, including Gerrards Cross, and in neighbouring towns such as Chalfont St Peter and Uxbridge. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Gerrards Cross?
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. 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.

Common questions
Can it work at night?
Some models include a light fitting in the diffuser.
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Do I need to be at home for the survey in Gerrards Cross?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Gerrards Cross?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
