Comprehensive Guide to Conservatory Prices: Comparing Sizes, Roof Types, and Key Cost Factors
Conservatory costs vary widely by size—from small to large structures—and roof materials like solid, glass, or polycarbonate. This guide breaks down price ranges, installation considerations, and hidden expenses, helping you plan your conservatory project efficiently.

Understanding Conservatory Price Ranges: Size and Material Impact 🏡📊
Choosing the right conservatory size and materials is the first step.
- Small conservatories (3m x 3m): Typically cost £9,000–£12,000
- Medium (4m x 4m): Expect £12,000–£18,000
- Large (5m x 5m): Budgets can exceed £20,000
Material choice matters:
- uPVC: Cost-effective, low maintenance
- Aluminium: Durable and sleek, but pricier
- Timber: Traditional look, higher maintenance
Your location can affect costs, with London and the South East often pricier.
Detailed Cost Breakdown of Conservatory Roof Types ⭐
🏠 Solid Roofs: Best for insulation; cost £6,000–£12,000 depending on size
🔎 Glass Roofs: Offer great light but need cleaning; price range £4,000–£9,000
🌤️ Polycarbonate Roofs: Most affordable; usually £3,000–£7,000
Key Tip: Solid roofs boost energy efficiency but cost 30%–50% more than polycarbonate. Glass strikes a balance between cost and aesthetics.
Additional Expenses to Anticipate for Your Conservatory Project ✅
Beyond obvious build costs, don’t overlook:
- Heating or underfloor heating: £500–£2,500
- Lighting & electrics: £500–£1,500
- Flooring: Laminate or tiles from £300 upwards
- Custom finishes or blinds: £300–£2,000
- Waste disposal: Confirm if it’s included in your installer’s quote
Pro-Tip: Allocate an extra 10% for unexpected adjustments due to unforeseen construction issues or minor design changes.
Planning Permission and Building Regulation Considerations 📜
Most UK conservatories fall under permitted development, so planning permission is not typically needed—unless you intend to build a very large space or live in a listed property.
Building regulations become vital if you opt for a solid or tiled roof.
- Typical local authority applications: £150–£500
- Always check with the local council to ensure compliance and avoid project delays.
