Sun tunnels & tubular skylights for Coleraine: the essentials
Sun tunnels & tubular skylights in Coleraine means light pipes that bring daylight to halls and bathrooms with no window. We cover the BT51 district and the rest of County Londonderry, with a survey before any price is fixed.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
We work across County Londonderry, including Coleraine, and in neighbouring towns such as Limavady and Ballymena. Access, parking and how the glass reaches the roof are all checked at the survey.

- Insulated tube sections
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes

Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation

Planning, building control and Coleraine
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Common questions
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
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.
