The cost of a conservatory in the UK typically ranges from £25,000 to £60,000+, depending on size, style, glazing options, and location. A lean-to or Victorian-style conservatory usually starts around £25,000–£35,000, while larger orangeries and bespoke glass extensions can exceed £40,000. Prices vary based on materials, foundation requirements, and whether planning permission is needed.
Most conservatories in the UK fall under Permitted Development and don’t require planning permission, provided they meet certain criteria: not more than 50% of your garden, single storey, no higher than 4m, and set back from boundaries. However, if you’re in a Conservation Area or have a listed building, you’ll likely need planning approval.
Installation times vary depending on the project scope. Most standard conservatories take 6–10 weeks from groundwork to completion. Larger orangeries or complex glass extensions may require 10–14 weeks. Our project managers provide a clear timeline tailored to your property and local weather conditions.
Orangeries generally cost 20–40% more than traditional conservatories due to their brick-built bases, solid roofing sections, and architectural detailing. While a conservatory offers a lighter, more affordable extension, an orangery provides a more seamless blend with your existing home—ideal for those seeking a premium finish.
