UPVC double glazing quotes for Cardiff’s bay-fronted terraces and suburban villas
Cardiff has one of the most consistent Victorian and Edwardian housing signatures of any UK city: the bay-fronted red-brick or Bath-stone-dressed terrace dominates Cathays, Roath, Grangetown and Canton. That means UPVC quotes here are almost always dealing with the same design brief — replicate the Edwardian bay-front’s proportions while hitting Uw ≤ 1.4. Legacy Windows is a quote comparison service that matches you with FENSA or CERTASS-registered installers who know Pontcanna and Roath Park conservation rules.

Frequently asked questions
Can I put UPVC on a Pontcanna or Roath Park conservation terrace? Both are conservation areas with tight rules on street-facing frames. UPVC is sometimes permitted where the profile carefully replicates the Edwardian bay-front glazing bar pattern, but timber-effect composite is a safer route on street elevations. Rear elevations usually have more latitude. Always check the Cardiff Council planning portal before ordering.
How is Wales different from England for Building Regs? Wales uses Part L of the Welsh Building Regulations, which broadly mirrors England but with some tighter thermal targets and specific Welsh Government policies on renewable-ready detailing. Notification is via FENSA or CERTASS as in England.
Typical Cathays or Roath terrace price? A full 7-9 window replacement including a bay usually lands £3,800 to £7,100 fitted. Individual apertures come in £400 to £790 depending on size, opener count and glass spec.
