| Property type | Windows | uPVC total | Aluminium total |
|---|---|---|---|

Glasgow housing stock considerations
- Sandstone tenements (West End, Southside, Pollokshields): often within conservation areas — require sash-style replacement or heritage-grade wooden frames
- 1950s-60s semis (Bearsden, Milngavie, Giffnock): standard casement uPVC works well and is cost-effective
- New-build estates (East Kilbride, outer Glasgow): typically A-rated already
- Building regs: Scotland uses a different system from England/Wales — installers must be FENSA or Certass registered under the Scottish scheme
Local planning considerations
Glasgow City Council administers multiple conservation areas including the West End, Park Circus, Pollokshields East, and Mount Florida. Listed buildings and conservation areas require additional planning consent — expect 6-10 weeks for approval. The Scottish Building Standards system differs from England’s — your installer should handle the paperwork.
