Rules in Wales

In Wales, replacement windows must meet 1.4 W/m²K, or a Window Energy Rating of band B or better. As in England, replacement windows are a controlled fitting: a competent person scheme installer self-certifies the work, or building control approves it.

Before ordering: 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

We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.

  • Guide prices published, not hidden
  • No pressure: the quote is yours to keep
  • Frames, glass and fitting in one contract
  • Advice on planning and consents before you order

Questions

Will the bay be warmer?

Yes. Replacing old double or single glazing in a bay with triple glazing cuts heat loss through the glass and makes the glass surface warmer, so the room feels less draughty.

Do bay windows need bay poles?

If the old frames carry load from above, yes. We check on survey and include support in the quote where needed.

Can I change a bay to a flat window?

That is a structural and planning change, not a like-for-like replacement. Ask and we will explain what it involves.

Do you cover all of Mid Glamorgan?

We arrange surveys and fitting across Mid Glamorgan.

Do I need permission for triple glazed bay and bow windows in Wales?

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