Reviewed byZaib Khan
Updated onSeptember 2026

A new polycarbonate roof on a medium Victorian conservatory typically costs £3,300 to £5,200, fitted.

Small£3,200£2,400 to £4,000
Medium£4,200£3,300 to £5,200
Large£5,300£4,300 to £6,400

A Victorian conservatory has a bay front with three or five facets, so its roof meets at a central hub with a hip bar running down each corner. That shape is what makes it the most recognisable conservatory in the UK, and also what makes its roof one of the more involved to replace.

New polycarbonate roofs on a Victorian conservatory

Polycarbonate suits the faceted shape easily and is the cheapest way to fix leaks, but the bay front magnifies the heat problem in summer.

  • Every facet needs its own cuts of tiles or glass, and every hip needs capping, so labour runs higher than on a square roof of the same size.
  • Inside, a tiled Victorian roof gives a vaulted, faceted ceiling that many people like more than a flat one.
  • The bay windows stay, so the room keeps plenty of daylight even under a solid roof.
