Rules for flats and apartments 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
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions from Merthyr Tydfil
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 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).
