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

How long do alu-clad windows take to make?

Typically 8 to 12 weeks from survey, sometimes longer for big projects.

Is alu-clad timber worth the extra cost?

It is for many self-builders and people planning to stay for decades, because the outside needs almost no upkeep and the timber inside looks warm. For a quick replacement on a typical semi, uPVC or aluminium give better value.

Do alu-clad windows suit Passivhaus builds?

Many alu-clad systems are designed for low-energy homes. If you need Passive House Institute certified components, ask and we will price systems that hold that certification.

Do you cover all of County Antrim?

We arrange surveys and fitting across County Antrim.

Do I need permission for alu-clad timber triple glazed 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.
