Sash Windows cost in Cardiff
Vertically sliding sash windows carry a 30–40% premium over casements due to the counter-balance mechanism and, where relevant, heritage joinery requirements.
| Material | Glazing | Estimated price range |
|---|---|---|
| uPVC | Double | £600 – £1,450 |
| uPVC | Triple | £950 – £1,800 |
| Timber | Double | £1,400 – £4,000 |
Prices are estimates derived from verified Cardiff casement baseline data (source: Checkatrade (Apr 2025) + HomeOwners Alliance) with a sash windows-specific multiplier applied. Fully-fitted supply and install including disposal and FENSA/Certass certification.
Cardiff note: Welsh labour rates sit below English averages; period-property scaffolding in Pontcanna adds a modest premium.
