How we approach sun tunnels & tubular skylights in Stevenage
Thinking about sun tunnels & tubular skylights in Stevenage? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Stevenage is around 31 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG1 district.

Planning and building rules for Stevenage
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.

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.
Will I need planning permission in Stevenage?
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.
Do I need to be at home for the survey in Stevenage?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
