What affects conservatory prices?
The six biggest factors that push your conservatory quote up or down.
Size & footprint
Priced per m². Doubling the footprint usually adds 60–80% to the cost.
Roof type
Polycarbonate is cheapest, glass mid-range, solid/tiled warm-roofs add £3,000–£8,000 but make the room usable year-round.
Frame material
uPVC standard. Aluminium adds ~35%. Timber used mainly in orangeries.
Groundworks
A standard concrete slab is included. Steel frames, retaining walls or tricky access push costs up.
Building regs
Most conservatories are exempt, but over 30m² or shared walls removed triggers full-plan approval (+£1,500).
Location
Greater London & the South East run ~20% above national average.
How much does a conservatory cost in 2026?
A typical Edwardian 4×4m conservatory costs £13,000–£17,000 installed with a standard glass roof. Orangeries cost roughly double due to brick piers, lanterns and more elaborate finishes.
Solid-roof replacements on an existing conservatory start at £3,200.
Which style is best?
- Edwardian — rectangular, maximises usable floor space. Most popular choice.
- Victorian — bay-fronted, traditional look. Good for period homes.
- Lean-to — cheapest, works well on bungalows & single-storey extensions.
- Orangery — brick piers, big lantern roof — closer to a proper extension.
Do I need planning permission?
Most conservatories fall under permitted development if they’re under 30m² and don’t extend beyond the rear wall by more than 3m (semi) or 4m (detached). Listed buildings & conservation areas always need consent.
