Triple glazing for flats and apartments in Swansea
From the first measure to the handover pack, we handle flat and apartment triple glazing for homes in Swansea and the rest of West Glamorgan.

Window replacement for flats, with the consents sorted first. Before replacing windows in a flat, check two things.
Winter light and glass choice in Swansea
Winter days in Swansea are short: about 7 h 49 min of daylight on 21 December, with the sun peaking near 15°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for flats and apartments 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
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.
- 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 Swansea
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.
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.
How long does it take to get flat and apartment triple glazing fitted in Swansea?
After the survey, typical manufacture time is 4 to 7 weeks, and most homes are fitted in 1 to 4 days.
Do I need permission for flat and apartment triple glazing in Swansea?
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.
