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
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 triple glazed uPVC windows look bulky?
The frames look much the same as good double glazed uPVC. The glass unit is thicker, but that sits inside the frame, so from outside the difference is hard to spot.
Do I need trickle vents?
In England and Wales, if your old windows had trickle vents, the new ones must have vents at least as big, and if they did not, the room must be no less ventilated than before. Scotland and Northern Ireland also require that replacement windows do not make ventilation worse. We size vents on the survey.
How much more is triple glazed uPVC than double?
Usually 20 to 30% more for the same window, though quotes in the UK range from about 15 to 40%. The written quote shows the triple price, and we can price double glazing alongside it if you want to compare.
Do you cover all of Mid Glamorgan?
We arrange surveys and fitting across Mid Glamorgan.
Do I need permission for triple glazed uPVC windows in Wales?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent.
