Frequently asked questions
How much does a conservatory cost in the UK?
A lean-to conservatory costs £8,000–£18,000. A Victorian or Edwardian conservatory costs £12,000–£30,000. An orangery costs £20,000–£50,000. Prices depend on size, glazing quality and base type.
Do I need planning permission for a conservatory?
Most conservatories are permitted development. However, if the conservatory covers more than 50% of the garden, is over 4m high, or is on a listed building, planning permission is required.
What is the difference between a conservatory and an orangery?
A conservatory has a predominantly glass roof and walls. An orangery has a solid roof with a central lantern light and brick or rendered walls. Orangeries are better insulated and feel more like a room extension.
How long does a conservatory take to build?
A standard conservatory takes 2–4 weeks to install. An orangery takes 4–8 weeks. This includes base preparation, frame erection, glazing and finishing.
Are conservatories worth it?
A well-built conservatory adds 5–10% to a property's value. However, a poorly insulated conservatory can be unusable in summer and winter. Investing in a solid roof or high-quality glazing significantly improves usability.
