Conservatory cost by style (2026 UK)
The biggest driver of price is the conservatory style: Lean-to (the cheapest) £8,000–£12,000; Victorian (most popular) £14,000–£20,000; Edwardian (square footprint, often best value per m²) £14,000–£22,000; Gable-front £18,000–£25,000; P-shape / T-shape £22,000–£28,000; Solid-roof orangery-style £25,000–£30,000+. All figures assume a dwarf-wall base and a registered FENSA/CERTASS installer.
How the roof choice changes the price
Polycarbonate is the cheapest (£500–£1,500 less than glass) but gives the worst thermal performance. Self-cleaning glass roofs are mid-range and the default for new builds. A solid tiled roof (Guardian, Ultraroof, SupaLite or equivalent) typically adds £6,000–£10,000 on a Victorian-size conservatory — but qualifies the room as habitable and avoids the summer-greenhouse effect.
Base, groundworks and extras
The dwarf-wall base is normally included on a turnkey quote. Add £2,000–£5,000 for tricky groundworks: tree-root diversion, soakaway, drain build-overs or sloping gardens. Internal extras add up fast: tiled floor (£2,000–£4,000), electrics with sockets and ceiling lights (£800–£1,500), wet underfloor heating (£2,500–£4,000) and integrated blinds (£1,500–£3,000).
What affects the price
Size, style, roof material, groundworks complexity and the installer's grade are the five biggest cost drivers. Smaller jobs come in slightly more expensive per m² because mobilisation and minimum-order fees do not scale down.
How to budget step by step
1. Pick the style
Lean-to is cheapest; Victorian and Edwardian are mid-range; gable, P-shape and orangery-style are the most expensive.
2. Decide on the roof
Polycarbonate is cheapest, glass mid-range, solid-tiled adds 25–40% to the build cost.
3. Factor in the base
Concrete dwarf-wall base and any tree-root or drain diversion add £2,000–£5,000.
4. Compare three matched quotes
FENSA or CERTASS-registered installers only, on the same written scope.
