Sash window replacements for Nether Edge, Sharrow and the Porter Valley
Sash windows are the defining feature of Sheffield’s late Victorian and Edwardian stone terraces, from the tall vertical sashes on Nether Edge Road to the narrower two-over-two units in Walkley. Getting the horns, glazing bars and cill projection right matters as much as the U-value here — the conservation officers in the south-west suburbs are notoriously particular. Legacy Windows is a quote comparison service that matches you with vetted installers experienced in both timber box-sash restoration and modern slim-profile UPVC sashes.

Frequently asked questions
Can I put UPVC sashes on a house in a Sheffield conservation area? It depends on the specific area’s Article 4 direction. Nether Edge and Broomhill will usually insist on timber or timber-alternative composite frames on street-facing elevations. Rear elevations are generally more flexible. Your installer should submit a design for approval before ordering — good ones do this as standard.
How much does a full timber sash restoration cost per window? Restoring an existing box frame (splicing sills, replacing sashes, draught-sealing, single or slim-glazed) usually runs £780 to £1,600 per window. Full replacement with new timber sashes and slim double glazing sits between £1,400 and £2,100. UPVC sash alternatives start around £780.
Do slim double-glazed units meet Part L? Slim units (typically 4-6-4 or 4-8-4) generally achieve Uw values around 1.6-1.8 W/m²K. That is above the 1.4 Building Regs target, but Part L allows a “historic building” exemption when full compliance would harm character — Sheffield planners accept this on conservation streets.
