What do sun tunnels & tubular skylights in Belfast involve?
We handle sun tunnels & tubular skylights across County Antrim, including Belfast. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Belfast is the main town we list in County Antrim; we also cover nearby Castlereagh and Newtownabbey.

Planning, building control and Belfast
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. Listed buildings also need listed building consent from the council.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.

Questions about sun tunnels & tubular skylights in Belfast
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.
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.
How do I book a survey in Belfast?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
