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
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.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions
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.
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.
What colours are available?
Woodgrain foils and heritage colours in uPVC, and any paint colour in timber or RAL colour in aluminium.
Do you cover all of Clwyd?
We arrange surveys and fitting across Clwyd.
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.
