What is skylight installation?
Our skylight installation service in County Antrim covers survey, supply and fit — new openings, extensions and fit-only work. We survey every job before fixing the price.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. 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
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. Listed buildings also need listed building consent from the council.
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
Is the survey free?
Yes, for new installations. Repair visits are charged.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Will I need planning permission in County Antrim?
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.
