Planning and building rules in Northern Ireland
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. Product data for building control is supplied with every quote.
For non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fragile-roof safety and access are planned before work starts.

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
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Do you work out of hours?
For occupied buildings we can plan phased or out-of-hours working where access allows.
Can rooflights double as smoke vents?
Some units are certified smoke ventilators. See our smoke-vent rooflights page.
Can you quote from drawings?
Yes, with a site survey to confirm.
Do I need to be at home for the survey in County Antrim?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
