Winter light and glass choice in Llanelli

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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Llanelli
Do I need building regulations for new bifolds?
Replacing an existing door is covered by the replacement rules. A new or widened opening is structural work that needs building control approval.
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.
Do I need permission for triple glazed bifold doors in Llanelli?
In Wales, householder rules do not cover flats, councils can use Article 4 directions, and listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
How long does it take to get triple glazed bifold doors fitted in Llanelli?
After the survey, typical manufacture time is 5 to 8 weeks, and a door is usually fitted in a day.
