Rules in Northern Ireland
Northern Ireland requires replacement windows to achieve 1.6 W/m²K, or a Window Energy Rating of band C or better, which good triple glazing passes comfortably. Replacing windows or external doors does not need full plans or a building notice, but the work must still comply; enlarging an opening or other structural change needs building control approval.
Before ordering: Check with your council planning office before changing the style, material or size of windows or doors, and always for listed buildings, conservation areas and flats.
How it works
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions
Are tilt and turn windows more expensive?
Our guide puts them about a quarter above a standard casement of the same size, in line with UK market figures.
Can I clean the outside from inside?
Yes. Turned fully open, both faces of the glass can be cleaned from inside the room.
Are they suitable as fire escape windows?
Turned fully open, they give a large clear opening, which often meets escape requirements. We check the size on survey.

Do I need permission for triple glazed tilt and turn windows in Northern Ireland?
In Northern Ireland, check with your council planning office before changing the style, material or size of windows, and always for listed buildings and flats.
