Rules in Northern Ireland

The rules for replacement windows in Northern Ireland are set by Technical Booklet F1 (2022): 1.6 W/m²K, or a Window Energy Rating of band C or better. 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

After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

  • Free survey and a written quote fixed for the specification
  • Glass build-up and whole-window U-value on every quote
  • Written handover pack at the end of the job
  • Guarantees on frames, units and fitting in writing

Questions

What is EnerPHit?

The Passive House Institute’s standard for retrofitting existing buildings, with slightly relaxed targets compared with new Passivhaus builds.

Is triple glazing enough for Passivhaus?

Triple glass is the starting point. The frame, spacers and installation all have to perform too.

Can you fit to my designer’s details?

Yes. We agree position, fixings and airtightness details with your designer before ordering.

Do you cover all of County Fermanagh?

We arrange surveys and fitting across County Fermanagh.

Do I need permission for Passivhaus and EnerPHit 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.
