How Much Does a Conservatory Cost?
Planning a conservatory involves understanding that prices vary widely depending on style, size, materials, and other specifications. There isn’t a one-size-fits-all price because every conservatory is made to measure to suit the exact needs of your home.
Typical Price Guide
As a general guide:
A standard conservatory often starts at around £15,000.
A basic 3 m × 3 m conservatory with no opening into the main house usually costs from this price.
If you add an opening into the house, expect prices to start from a bit higher, for example around £19,000 or above.
Keep in mind these figures are indicative and not exact quotes — actual costs depend on many choices you make.

Conservatory Style Influences Cost
Different conservatory designs can change the price you pay:
Lean-to Conservatories
Simple and popular design
Usually the most budget-friendly option because of its straightforward shape and construction.
Victorian Conservatories
Traditional style with bay windows and decorative rooflines
Typically about 25 % more expensive than a basic lean-to conservatory due to additional materials and detailing.
Edwardian Conservatories
Square or rectangular shape offering more usable interior space
Also around 25 % more than a lean-to style because of increased glazing and structure.
Materials Affect Price Too
The frame and materials you choose also influence total cost:
uPVC — Often the most economical option with good insulation and low maintenance.
Aluminium — Sleeker and slightly more expensive than uPVC, typically around 25 % more.
Timber — Premium option with classic aesthetics, costing around 50 % more than basic uPVC designs.
Roof Style & Extras
How you design the roof — whether fully glazed, partially glazed, or hybrid solid roof — will also affect price. More complex roofs or better-insulated solutions can add to the overall budget.
Why Prices Vary Widely
Prices can differ greatly because:
- Every conservatory is custom-made to your specifications.
- Size, shape, roof type, glass quality, foundations, internal features, and finishing details all influence the total cost.
- Quoted prices from companies often include bespoke surveys and tailored plans before final pricing is confirmed.
