What are sun tunnels & tubular skylights?
Sun tunnels & tubular skylights in County Londonderry means light pipes that bring daylight to halls and bathrooms with no window. Every quote follows a survey of the roof and the room below.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways.

Planning and building rules in Northern Ireland
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.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Common questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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.
Can it work at night?
Some models include a light fitting in the diffuser.
Do I need to be at home for the survey in County Londonderry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
