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
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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions
Do I need permission to replace windows in my flat?
Often, yes. In England and Wales flats have no householder permitted development rights, so check with the council; in Scotland permission is generally needed only if the opening size changes or the flat is in a conservation area; in Northern Ireland ask your council. Separately, check your lease (England, Wales and Northern Ireland) or title deeds and factor (Scotland).
Can windows in a flat be fitted from inside?
Often yes, which avoids scaffolding. It depends on the window design and access, checked on survey.
Is triple glazing good for a flat on a busy road?
Yes, especially with an acoustic laminated pane, which makes the bigger difference to noise.
Do you cover all of Dyfed?
We arrange surveys and fitting across Dyfed.
Do I need permission for flat and apartment triple glazing in Wales?
