A Complete 2025 Guide to Conservatory Prices and Installation Costs in the UK
Adding a conservatory to your home is a smart way to increase space, natural light, and overall property value. Whether you prefer a classic Victorian conservatory, a modern orangery, or a bespoke custom design, understanding the cost is essential. You can also explore our home extension services if you're considering a larger property upgrade.
In this comprehensive 2025 guide, we break down conservatory prices, installation costs, roof options, planning requirements, and money-saving tips to help you plan your perfect conservatory project with confidence.
The cost of a conservatory depends on several key factors. Here’s what you need to consider before budgeting for your new space:
Naturally, the larger your conservatory, the higher the cost. Standard small conservatories (around 3m x 3m) are more affordable, while custom-built or larger designs increase material and labor expenses per square meter.
Your chosen style significantly impacts the price:
Lean-to or Victorian conservatories: Budget-friendly, simple designs.
Edwardian conservatories or bespoke orangeries: More complex construction and premium materials make them costlier.
For inspiration on different looks and layouts, explore our conservatory build & maintenance guide.
Materials directly affect your budget:
uPVC: Affordable and low maintenance.
Aluminum or hardwood: Higher quality and more expensive.
Roof materials also vary: polycarbonate, glass, or solid roofs each come with different costs and benefits.
Roof choice affects both installation and energy costs:
Polycarbonate Roofs: Lightweight, budget-friendly.
Glass Roofs: Stylish, light-enhancing, but pricier.
Solid Roofs: Excellent insulation for year-round use, higher cost upfront.
Check whether planning permission is required, especially in conservation areas or for larger builds. Small conservatories often fall under permitted development, but approval may be needed for certain projects, adding to overall costs.
