Sash Windows cost in Southampton
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 | £800 – £2,050 |
| uPVC | Triple | £1,200 – £2,850 |
| Timber | Double | £1,950 – £5,650 |
Prices are estimates derived from verified Southampton 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.
Southampton note: South-east cost base pushes labour 10-15% above Midlands; port logistics keep material supply steady.
