Rules for sash windows in Northern Ireland

In Northern Ireland, replacement windows must meet 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.

Planning: 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 from Magherafelt

Are uPVC sashes allowed in conservation areas?

It depends on the council and any Article 4 direction. Timber is often expected on front elevations. Check before ordering.

Will triple glazing make my sashes heavy to lift?

The balances are sized for the sash weight, so they should slide smoothly. Heavier sashes use stronger balances or weights.

Do I need permission for triple glazed sash windows in Magherafelt?

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. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.

How long does it take to get triple glazed sash windows fitted in Magherafelt?

After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.
