Skylights and rooflights across County Antrim
Skylights, roof lanterns and roof windows fitted throughout County Antrim, from Belfast to Newtownabbey, after a survey and a fixed written quote.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting.

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
Do you cover all of County Antrim?
Yes. We survey and fit across County Antrim, including Belfast, Lisburn and Newtownabbey. Remote and island addresses are by arrangement.
Do I need planning permission for a rooflight in County Antrim?
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall.
Is the survey free?
Yes, for new installations. Repair and maintenance visits are charged, and we tell you the visit price first.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
Do I need building regulations approval?
New openings and extensions go through building control. In England and Wales, replacements can often be self-certified through a competent person scheme; Scotland and Northern Ireland have their own routes. We tell you which applies.
