Sun tunnels & tubular skylights in Ampthill: what is involved?
Thinking about sun tunnels & tubular skylights in Ampthill? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.

Consents for sun tunnels & tubular skylights in Ampthill
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Sun tunnels & tubular skylights in Ampthill: questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
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.
Will I need planning permission in Ampthill?
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.
Can you work alongside my builder in Ampthill?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
