How Much Does a Conservatory Cost in 2025? Your Complete Price Guide

Dreaming of a bright, airy conservatory to extend your living space? Whether you’re envisioning a cozy retreat or a spacious family room, understanding the cost of a conservatory in 2025 is the first step to making it a reality. Prices fluctuate based on size, style, materials, and installation complexity, ranging from a modest £5,000 to a luxurious £30,000+. This guide dives into every detail—from lean-to designs to Victorian masterpieces—covering material costs, labor, and hidden fees, so you can budget wisely for your perfect home addition.

Why Conservatory Costs Vary

No two conservatories are priced alike. The final cost hinges on factors like the style (lean-to, Victorian, Edwardian, or P-shaped), the size of the structure, the materials (uPVC, aluminum, or timber), and whether you need groundwork or planning permissions. A small 10m² lean-to might cost £5,000, while a 20m² Victorian with a glass roof could soar past £20,000. Location matters too—labor in London is pricier than in rural areas—and premium brands like Ultraframe or Everest add a markup. Let’s break it down.

Lean-to Conservatory Costs

Lean-to conservatories are the budget-friendly choice, ideal for smaller homes or simple extensions. With their minimalist, sloped-roof design, they’re quick to install and use fewer materials. For a 10m² lean-to with uPVC frames and a polycarbonate roof, expect costs between £5,000 and £10,000, including installation. Opt for glass or premium brands like Anglian, and you’re looking at £8,000 to £12,000.

Supplier	Average Cost	Cost Including Installation
Wickes	£4,500	£7,000
Anglian	£6,000	£9,500
Everest	£7,000	£11,000

Victorian Conservatory Costs

Victorian conservatories bring elegance with their curved bays and ornate details, perfect for period homes. A 15m² model with uPVC and a glass roof typically ranges from £10,000 to £18,000, including installation. Timber frames or tiled roofs push costs toward £20,000+, especially with brands like Ultraframe offering superior craftsmanship.

Supplier	Average Cost	Cost Including Installation
Wickes	£9,000	£13,000
Anglian	£11,000	£16,000
Ultraframe	£13,000	£18,500

Edwardian Conservatory Costs

Edwardian conservatories offer a square, symmetrical look with maximum floor space. For a 15m² version with uPVC and a polycarbonate roof, costs range from £9,000 to £15,000. Glass roofs or aluminum frames can bump it to £17,000, with premium suppliers like Everest at the top end.

Supplier	Average Cost	Cost Including Installation
Wickes	£8,000	£12,000
Anglian	£10,000	£14,500
Everest	£11,500	£16,500

P-shaped Conservatory Costs

P-shaped conservatories blend a lean-to with a Victorian or Edwardian section, offering versatile space for larger homes. A 20m² P-shaped unit with uPVC and a glass roof costs £15,000 to £25,000, while tiled roofs or timber frames can hit £30,000 with top-tier suppliers.

Supplier	Average Cost	Cost Including Installation
Wickes	£13,000	£18,000
Anglian	£16,000	£22,000
Ultraframe	£18,000	£25,500

Hidden Costs to Watch For

The base price isn’t the whole story. Groundwork like leveling or foundations can add £1,000-£5,000, depending on the site. Planning permissions, if required, cost around £200-£500. Upgrades like underfloor heating (£1,500-£3,000), double glazing enhancements (£500-£1,000), or a tiled roof conversion (£4,000-£8,000) boost comfort but inflate the bill. Don’t forget ongoing maintenance—cleaning and repairs might run £100-£300 annually.

Efficiency and Long-Term Value

Investing in energy-efficient features—like double or triple glazing and insulated roofing—can cut heating costs by £100-£200 yearly, especially in all-season conservatories. A £15,000 conservatory with a tiled roof might add £20,000+ to your home’s value, making it a smart long-term move. Compare this to a basic polycarbonate setup with minimal resale impact.

When to Build a Conservatory

Timing matters. Spring or summer construction avoids weather delays, but if your current extension is drafty, leaking, or too hot in summer, don’t wait—upgrade now. A 20-year-old conservatory with faded frames or cracked glazing is likely due for replacement to restore functionality and aesthetics.

Final Thoughts on Conservatory Costs

In 2025, conservatory costs range from £5,000 to £30,000+, depending on style, materials, and extras. Lean-to designs suit tight budgets, while Victorian or P-shaped models offer luxury and space.
