Triple glazing for period homes and conservation areas in Swansea
Looking at period-style triple glazing for a home in Swansea? We survey, quote and fit across West Glamorgan, and the SA1 postcode district is part of that.

Warmth for period homes without losing their character. In a conservation area, replacing windows on a house is often permitted development if the new windows look similar to the old ones, but councils can remove those rights with an Article 4 direction.
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 period homes and conservation areas in Wales
Wales requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. 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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

Can I have triple glazing in a conservation area?
Often yes, if the new windows match the look of the old ones and there is no Article 4 direction. Check with your council first.
