Sun tunnel installation in County Antrim

No two sun tunnels in County Antrim cost exactly the same to fit, and a guide price only gets you so far. What moves it: the size and weight of the unit, whether a new opening is needed, the roof covering, scaffold or lifting needs, and how much internal finishing you want. We quote sun tunnel installation across County Antrim with each of those spelt out. Send photos for a first figure, or arrange a survey where the job calls for one.

Towns we list in County Antrim

From the larger towns to the smaller places in between, we take on rooflight fitting across County Antrim. The process is the same for a terrace, a farmhouse extension or an industrial unit: details first, written quote second, fitting day third. Remote and island addresses in Northern Ireland, where they arise, are covered by arrangement, and we tell you that before quoting.

Rathlin Island is covered by arrangement, with travel priced into the quote before you commit.

Included in the work

  • Ceiling opening cut neatly and the diffuser fitted
  • Dust cleared from the room below and the loft
  • Dome fixed and sealed on top of the flashing
  • Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
  • Tube size — We match the tube size to the room and the roof.

Rules that apply in Northern Ireland

Northern Ireland's building regulations set a minimum of WER Band C or 1.6 W/m²K for rooflights and roof windows in existing homes, assessed under Technical Booklet F1. New openings involve trimming the roof structure, so expect a building control application. Many house rooflights don't need planning permission, but conservation areas and listed buildings are excluded, and side windows near a boundary have obscure-glazing rules. We confirm what applies.

Common questions in County Antrim

Does a rooflight need building control approval?

In Northern Ireland a new opening alters the roof structure, so expect a building control application; confirm the position with your council, including for replacements. The new rooflight must meet WER Band C or 1.6 W/m²K. We confirm what applies before you commit.

Will my new sun tunnel leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
