Winter light and glass choice in Colwyn Bay

Rules for bifold doors in Wales
Wales sets replacement door limits through Approved Document L for Wales (2022 edition, with 2024 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules as windows: 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 of a front door.
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 door U-value on every quote
- Written handover pack at the end of the job
- Guarantees on frames, units and fitting in writing
Questions from Colwyn Bay
Are bifolds warmer with triple glazing?
Yes. The glass is most of the door area, so triple units cut heat loss and keep the inner surface warmer.

Replacing an existing door is covered by the replacement rules. A new or widened opening is structural work that needs building control approval.

Do I need permission for triple glazed bifold doors in Colwyn Bay?
