# Conservatories: 10 Frequently Asked Questions
## 1. How much does a conservatory cost in the UK in 2026?
Costs depend heavily on type, size, and material. A basic lean-to UPVC conservatory starts from £5,000-£10,000. A mid-range Victorian or Edwardian style conservatory costs £15,000-£25,000. An orangery costs £25,000-£40,000 mid-range and £40,000-£80,000+ premium. A fully insulated garden room costs £20,000-£35,000 mid-range.
