Rules in Wales

The rules for replacement windows in Wales are set by Approved Document L for Wales (2022 edition, with 2024 amendments): 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

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.

Questions

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.

What about tall blocks?

Higher-risk buildings (18 m or 7 storeys and over in England) have extra building safety requirements. Talk to your building’s accountable person first.

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.

Do you cover all of West Glamorgan?

We arrange surveys and fitting across West Glamorgan.

Do I need permission for flat and apartment triple glazing in Wales?

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