Conservation rooflights in County Antrim: the essentials
Across County Antrim, our conservation rooflights work covers slim, low-profile steel-look rooflights for period and listed roofs. Survey first, fixed price second, fitting third.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. 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
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.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
