Quick price answer: Current fitted market benchmarks put a 600 × 900 mm timber casement around £925, a 1200 × 1200 mm casement around £1,200 and a comparable larger timber sash around £1,650.
Current timber window benchmarks
Timber varies much more than standard uPVC because softwood, engineered timber, hardwood, joinery detail and factory finishes all affect the price.
Why wooden windows cost more
Timber needs more fabrication, finishing and skilled joinery than a mass-produced standard uPVC frame. Hardwood, heritage profiles, glazing bars, bespoke paint colours and conservation-style detailing can all push the cost higher.
Timber casement vs timber sash
Casements are normally the cheaper timber option. Sash windows use more complex balances, hardware and joinery, so a comparable sash replacement can cost substantially more even at a similar opening size.
- Engineered timber can control movement and cost
- Hardwood and heritage specifications sit higher
- Maintenance and repainting should be budgeted over the life of the frame
