Sash Windows cost in Portsmouth
Vertically sliding sash windows carry a 30–40% premium over casements due to the counter-balance mechanism and, where relevant, heritage joinery requirements.

|---|---|---|
| uPVC | Double | £800 – £2,050 |
| uPVC | Triple | £1,200 – £2,850 |

Prices are estimates derived from verified Portsmouth 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.
Portsmouth note: Conservation-area jobs in Southsea carry a premium; outer estates offer straightforward, lower-cost replacements.
