Conservatory Cost UK 2026: Full Price Guide by Style & Size
A UK conservatory typically costs £8,500–£32,000 supplied & fitted in 2026, with most homeowners spending £12,000–£22,000. Price is driven by style (lean-to vs Victorian vs orangery), size (3x3m vs 5x4m), glazing spec (standard double-glazed vs solar-control vs self-cleaning), roof type (polycarbonate vs glass vs solid tiled roof) and the region. A typical 4x3m P-shape uPVC conservatory with a tiled solid roof lands at £18,500–£24,500 in 2026 — the most popular spec for UK semis since 2023.
How much does a conservatory cost in 2026?
Typical 2026 UK conservatory costs (supplied & fitted, including base):
- Lean-to (3x3m) — £8,500–£13,500
- Edwardian (3.5x3.5m) — £12,000–£18,000
- Victorian (4x3.5m, 3 facets) — £13,500–£19,500
- P-shape (4.5x3.5m + 2m return) — £17,500–£24,500
- Orangery (4x4m brick piers, glass lantern) — £22,000–£32,000
Add £2,200–£5,800 for a solid tiled roof (vs polycarbonate), £1,400–£2,800 for premium solar-control glazing, and £1,600–£4,200 for bifold doors instead of French doors. Most conservatories under 30m² fall under Permitted Development — no planning needed.
Conservatory Cost by Style
Style choice changes the visual character and the price. Here’s what each option costs in 2026 with mid-range uPVC frames, double-glazed glass and a polycarbonate roof unless noted.
Lean-to (Mediterranean)
Simple rectangular shape with a single-pitch roof sloping away from the house. Cheapest style, fastest install (5–7 days), best for bungalows and modern semis where roof clearance under the first-floor windows is limited.
Edwardian (square / rectangular)
Classic four-sided pitched roof rising to a central ridge. Maximises internal floor area for a given footprint — the most usable square metre per pound. Most popular style for new conservatories from 2015–2022.
Victorian (3 or 5 facets)
Period feature with 3 angled facets (or 5 for grand designs) creating a faceted bay window effect. Steep pitched roof with ornate crestings and finials. Suits Victorian and Edwardian period homes. Slightly less efficient on floor area than Edwardian for the same width.
P-shape (Victorian + Lean-to combination)
Larger combination shape: Victorian-style main bay with a lean-to return creating an L. Best for separating a dining area from a lounge area within the same conservatory. Needs a wider rear elevation (5m+) to look balanced.
Orangery (brick piers + glass lantern roof)
Brick piers between glazing panels with a flat or shallow-pitched roof topped by a glass lantern. Feels more like a true extension than a conservatory — can be used year-round without overheating. Best ROI for properties valued £450k+.
What Drives the Final Bill
Two conservatories on the same street can quote £5,000 apart for the same footprint. The six drivers that explain the spread:
1. Roof type
Polycarbonate roof: baseline (cheapest, but noisy in rain, overheats in summer). Glass: +£1,800–£3,500. Solid tiled (Guardian, LivinROOF, Equinox): +£2,200–£5,800. The solid roof has become the default for new builds since 2023 because it converts the room from “summer-only” to year-round usable.
2. Glazing spec
Standard 28mm double glazing: baseline. Solar-control low-E glass (Pilkington Activ, Saint-Gobain Cool-Lite): +£1,400–£2,800 total. Triple glazing: +£2,400–£4,800 total — useful in North-facing aspects, marginal benefit south-facing.
3. Door type
Standard French doors: included. Sliding patio doors: +£400–£900. Aluminium bifold doors (3-pane, opening): +£1,600–£2,800. 5-pane bifold: +£2,800–£4,200. Bifolds give the entire side wall opening to the garden in summer.
4. Base & foundations
Standard 600mm strip foundation + concrete slab: £2,200–£4,400. Pile foundations (poor ground, sloping site, tree roots within 5m): +£1,800–£4,200. Existing patio that needs full removal first: +£600–£1,400.
5. Frame material
uPVC: baseline. Aluminium (slimmer sightlines, contemporary look): +25–35% on frame cost. Hardwood (oak, accoya): +50–80% — usually only orangeries. Composite hybrid (aluminium outside, wood inside): +40–60%.
6. Region
London: +25–35% on the same spec. South East +15%. Wales, Scotland and the North 5–12% below the UK average. Trickier-access sites (rear-garden only through the house, no side access) add £600–£1,400 labour.
Conservatory Cost by UK Region
Based on 320+ recent UK conservatory quotes, 4x3.5m P-shape uPVC, solid tiled roof, French doors, mid-range spec:
Real Project: 4x3.5m P-shape, Leeds LS6
3-bed semi-detached in Headingley. Rear south-west garden. P-shape uPVC conservatory replacing an old 1990s lean-to. Solid tiled Equinox roof, two Velux roof windows, French doors to the garden plus a side single door. Completed March 2026.
| Strip-out existing lean-to + skip | £680 |
| Foundations + dwarf wall + concrete slab | £4,200 |
| uPVC frames + glass (anthracite grey) | £5,800 |
| French doors + side single door | £1,400 |
| Equinox solid tiled roof + 2 Velux | £5,400 |
| Plastered ceiling + 4 downlighters | £1,250 |
| Tiled floor + skirting | £1,400 |
| Electrics: 4 sockets, mains alarm spur | £820 |
| Plumbed radiator off central heating | £700 |
| Total (8 working days on site) | £21,850 |
Valuation uplift: £392,000 pre-works → £415,000 post-works (RICS appraisal, April 2026). Net value-add roughly £1,150 — conservatories rarely return more than their build cost, but a tiled roof + plastered ceiling spec lifts ROI vs polycarbonate.
