Frequently Asked Questions
How much does a conservatory cost in the UK in 2026?
A typical UK conservatory costs £12,000–£40,000 in 2026. A small lean-to with polycarbonate roof starts around £8,500. A large orangery with solid tiled roof and bifold doors can reach £60,000+. Most homeowners spend £15,000–£25,000 for a medium Victorian or Edwardian.
What is included in a conservatory quote?
A full conservatory quote should include foundations, base (dwarf walls or full glazing to floor), UPVC or aluminium frame, roof glazing or panels, French or bifold doors, and basic electrics (sockets, lighting). Check whether internal plastering, flooring and radiators are included — they often aren't in the headline price.
Do I need planning permission for a conservatory in 2026?
Most conservatories fall under Permitted Development and don't need planning permission, provided they are under 50% of the original garden area, not higher than 4m, and not forward of the principal elevation. Listed buildings and conservation areas always need full planning permission.
How long does a conservatory take to build?
A medium conservatory typically takes 6–10 weeks from ground-breaking to completion. A garden room or orangery can take 12–20 weeks. Allow additional time for planning permission if required.
Is a conservatory a good investment?
A well-built conservatory with glass or solid tiled roof adds 5–10% to property value. Polycarbonate roofed conservatories add less value. An insulated garden room is increasingly popular with buyers and often commands a premium.
