How This Calculator Works
Our conservatory roof calculator combines the roof system, roof area, conservatory style and region with real 2026 UK supply-and-fit pricing from vetted roofers and conservatory installers across our 519-town database.
System Rates (per m², fitted)
- Replacement polycarbonate — £190–£320/m²
- Insulated roof panels — £250–£350/m²
- Glass (solar-control units) — £380–£560/m²
- Solid tiled (lightweight) — £700–£1,100/m²
- Style uplift: Victorian/Edwardian +12%, P- or T-shape +22% (extra cuts, hips and flashings)
Rates include stripping the old roof, the new system, flashings, trims, labour and VAT.
Assumptions & Adjustments
- Frames must pass a structural survey — lightweight tile systems weigh roughly 10–25 kg/m²
- Solid conversions include plasterboard ceiling, insulation and building-control sign-off
- Optional extras: roof window +£500, insulated pelmet with downlights +£900
- Region multipliers: London +27% … Northern Ireland −12% (Midlands baseline)
- Estimate only — a firm quote always follows a site survey
Converting a translucent roof to a solid roof is building work — building regulations approval applies.
