Made-to-measure vertical sliding sash windows in modern uPVC — period-correct sightlines, modern thermal performance. Suits Victorian, Edwardian and Georgian properties where you want the original sash look without the maintenance, draughts or rotting frames of timber. White as standard, plus 7 foiled colour finishes including period-correct cream and Anthracite Grey.
Standard white at the base price. Foiled colour finishes add approximately £80–£140 per window:
Modern uPVC sash windows give the period look of timber at roughly half the price, with none of the maintenance overhead. Timber sashes need painting every 5–7 years and are vulnerable to rot at the cill where rainwater pools. uPVC stays flush, doesn't rot and wipes clean with soapy water. The visual difference from the street is minimal — modern profiles use slim sash members (50–65mm) and authentic horns that read as period-correct from 2 metres away.
If your property is in a conservation area, most local authorities accept slim-profile uPVC sashes with mock-Georgian bars and a foiled colour. Listed buildings almost always require timber — check with your local planning before ordering. We don't supply for listed work.

Made to measure. Typical range is 400–1300mm wide × 700–2000mm tall per sash. Standard Victorian and Edwardian replacement sashes (typically 850×1500mm or 900×1700mm) sit comfortably in this range. Bay window sashes available — flag the bay configuration in your quote request.
Plain 2-over-2 (single pane top and bottom — classic Victorian), 6-over-6 Georgian, 1-over-1 modern, mock-Georgian (bars between the panes for easy cleaning), or square Crittall-style grids. Astragal bars (true divided light) also available. Pick what matches your property's age — we can advise on the right pattern for any era of UK home.
From the street, yes. Modern uPVC sash windows use slim-profile sashes, true sash horns and authentic glazing-bar patterns that read as period-correct from 2 metres away. The big visual difference is the surface finish — uPVC is smooth, timber has grain. Foiled wood-grain finishes (Rosewood, Light Oak) close even that gap.
Yes. Modern uPVC sash windows use multi-chambered profiles and standard 28mm A-rated double-glazed units, achieving the same thermal performance as a casement equivalent. They typically score WER A-rated and meet UK Part L requirements for replacement windows in conservation areas where original-style is required.
Conservation areas: usually yes, provided the new windows match the original sightlines, glazing bar pattern and colour. Many councils accept slim-profile uPVC sash with mock-Georgian bars and a foiled colour. Listed buildings: usually no — listed properties almost always require timber. Always check with your local planning authority before ordering.
