Sun tunnels & tubular skylights in Walton-on-Thames: what is involved?
Thinking about sun tunnels & tubular skylights in Walton-on-Thames? 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. In Walton-on-Thames, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
We work across Surrey, including Walton-on-Thames, and in neighbouring towns such as Sunbury-on-Thames and Esher. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Walton-on-Thames
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.
Read the planning permission guide before you commit to a design.

Questions about sun tunnels & tubular skylights in Walton-on-Thames
Do sun tunnels need planning permission?
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.
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.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Will I need planning permission in Walton-on-Thames?
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.
