YOUR QUESTIONS ANSWERED
Common Questions About Glass Extensions
Find answers to the most common questions about our conservatories, orangeries, and glass extensions.
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.
In many cases, glass extensions and conservatories fall under Permitted Development rights in the UK, meaning planning permission is not required. However, rules differ in England, Scotland, Wales, and Northern Ireland, and restrictions apply for listed buildings or conservation areas. We always recommend a free planning check with our team.
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.
Depending on your product choice and your location, we generally offer a comprehensive service which includes:
- Free home visit by one of our design experts
- Bespoke 3D visualisations showing how your extension will look

Developed by Room Outside, New Generation Glass is an advanced glazing technology designed for better thermal efficiency and noise reduction. Unlike traditional conservatory glass, it helps maintain comfortable temperatures year-round—keeping spaces warm in winter and cool in summer—making it ideal for modern glass extensions in the UK climate.
Depending on your product choice and your location, we generally offer a 10-year structural guarantee on all our conservatories and glass extensions, alongside product-specific warranties on glazing, roofing, and materials. Our guarantees are backed by trusted UK insurers, giving you peace of mind for years to come.
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.
Modern glass extensions require minimal maintenance thanks to New Generation Glass technology and high-quality materials. Regular cleaning with a mild glass cleaner and occasional checks of seals and mechanisms are typically all that’s needed. Our glass extensions are designed for durability and require far less maintenance than traditional conservatories, saving you time and money in the long run.
