What shape is your conservatory?
Pick the closest match — you can refine later.
Cost by roof type
The single biggest factor is the type of roof you choose. Lighter options reuse more of your existing structure and fit in a day or two; a solid warm roof is a full insulated conversion with a plastered ceiling, building-control sign-off and the highest comfort. Typical fitted prices for a mid-sized (around 4m × 4m) conservatory:
| Roof type | Typical installed cost | What you get |
|---|---|---|
| Polycarbonate | £2,000 – £6,500 | Budget like-for-like refresh; still noisy and poor insulation |
| Glass (solar-control) | £3,500 – £9,500 | Maximum light, with self-cleaning, heat-reflective glass |
| Insulated panels | £4,000 – £8,000 | Fast thermal upgrade that slots into the existing frame |
| Lightweight tiled | £5,000 – £12,000 | Warm, quiet, tiled look — a true year-round room |
| Hybrid (solid + glass) | £5,500 – £13,500 | Solid warmth plus glazed panels or a lantern for light |
| Solid warm roof (plastered) | £6,500 – £15,000 | Extension-grade insulation and a plastered vaulted ceiling |
Cost by conservatory style and size
Bigger conservatories and more complex shapes (more roof facets and valleys) cost more to re-roof. The table below shows typical prices for the most popular upgrade — a solid warm roof— across styles and sizes. Lighter roof types cost less; the calculator above prices your exact spec.
| Conservatory style | Small | Medium | Large |
|---|---|---|---|
| Lean-to / sunroom | £3,800 – £5,200 | £7,500 – £10,500 | £10,000 – £15,000 |
| Edwardian / Georgian | £6,100 – £8,500 | £8,000 – £12,000 | £10,000 – £15,000 |
| Victorian (3/5 facet) | £6,700 – £9,350 | £9,200 – £13,800 | £11,500 – £17,250 |
| Gable-fronted | £6,400 – £8,900 | £8,400 – £12,500 | £10,500 – £15,750 |
| P / T / L-shaped | — | £8,500 – £12,500 | £12,500 – £18,000 |
What drives the price
- Roof type & size — the material and the roof's surface area set the base cost.
- Shape complexity — Victorian and P/T/L-shaped roofs have more facets and valleys, so they cost 15–40% more than a simple lean-to.
- Internal finish — a standard plastered ceiling is included; pine cladding or a vaulted ceiling with exposed beams adds £800–£2,500.
- Roof windows — each Velux-style window adds roughly £900–£2,500 fitted.
- Lighting & electrics — integrated downlights typically add £500–£1,500.
- Structural reinforcement — frames built before 2000 sometimes need steel "goalpost" supports for a solid roof (+£1,500–£2,500), confirmed on survey.
- Region — labour and overheads vary across the UK (see below).
Regional price differences
Where you live changes the price noticeably — the South-East and London carry the biggest premium:
| Region | Typical price vs UK average |
|---|---|
| Greater London | +25% |
| South-East / Home Counties (Herts, Surrey, Berks) | +15% |
| South-West | +5% |
| Midlands / East Anglia | Baseline |
| North-West / Wales | −5% |
| North-East / Scotland | −10% |
The £9,000 vs £19,000 question
It's common to get a £9,000 quote from a local independent and a £19,000 quote from a national brand for the same roof. Accredited local installers typically charge £8,000–£12,000 for a standard solid conversion; national brands carry far higher marketing and sales overheads. We match you with one vetted local installer — not a call centre — so you see realistic local pricing.

Conservatory roof cost — FAQs
›How much does it cost to replace a conservatory roof in 2026?
For a typical mid-sized conservatory, expect roughly £2,000–£6,500 for polycarbonate, £3,500–£9,500 for glass, and £6,500–£15,000 for a solid warm (tiled, plastered) roof. The exact price depends on the roof type, your conservatory's size and shape, and your region.
›Is replacing the roof cheaper than a new conservatory?
Almost always. Replacing just the roof keeps your existing frames, base and glazing, so it's far less disruptive and typically costs a fraction of demolishing and rebuilding — or of a full brick extension.
›Why do quotes vary by thousands of pounds for the same roof?
Three big reasons: local independents usually quote £8,000–£12,000 for a standard solid roof while national brands often quote £15,000–£20,000+ for the same job; older frames may need structural reinforcement; and finishes (plaster vs pine, extra roof windows, lighting) add up. Always compare like-for-like.
›Can I spread the cost / pay monthly?
Many installers offer finance so you can spread the cost over several years — ask your installer about the rates and options available.
›Does a new solid roof add value to my home?
It turns a seasonal, often-unused conservatory into a year-round room, which buyers value. Crucially, keep the Building Control completion certificate — solicitors ask for it when you sell.
