What are sun tunnels & tubular skylights?
Our sun tunnels & tubular skylights service in County Down covers light pipes that bring daylight to halls and bathrooms with no window. We survey every job before fixing the price.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending.

Planning and building rules in Northern Ireland
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. 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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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.
Can it work at night?
Some models include a light fitting in the diffuser.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
