Sage green flush casement windows on a whitewashed English cottage

A softer, flatter face for cottages and older homes. A flush casement window has sashes that close flush with the outer frame instead of overlapping it, copying the look of traditional timber windows.

Rules in Wales

Wales requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.

Planning: Householder permitted development rules do not cover flats, and councils can remove rights with Article 4 directions. Listed buildings need listed building consent. Check with your council before changing the style or material.

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.

  • Guide prices published, not hidden
  • No pressure: the quote is yours to keep
  • Frames, glass and fitting in one contract

Questions

Can flush casements be triple glazed?

Yes. The frame depth and hardware are chosen for the unit weight; we confirm the exact unit on your quote.

Are flush casements more expensive?

Yes. Our guide puts them about 30% above a standard uPVC casement of the same size.

Will they be accepted in a conservation area?

Flush designs are often the closest match to original timber windows, but each council decides. See our conservation guide and check any Article 4 direction.

Do you cover all of Dyfed?

We arrange surveys and fitting across Dyfed.

Do I need permission for triple glazed flush casement windows in Wales?

In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
