Conservatory Roof Replacement Cost: Solid Tiled vs Glass (2026)
Conservatory roof replacement cost depends mostly on the roof you choose. A basic polycarbonate roof is the cheapest. A solid tiled roof costs the most. This guide sets out typical UK prices for 2026, so you can budget before you ask for quotes.
What is the average conservatory roof replacement cost?
For a typical conservatory of 3m by 3m up to 4m by 4m, most homeowners pay around £4,000 to £8,000. However, the range is wide. Roof type, size and access all change the final figure. These are typical ranges, including materials and fitting:
- Polycarbonate roof: £2,000 to £6,500
- Glass roof: £3,300 to £9,500
- Hybrid roof (glass and solid panels): £5,500 to £13,500
- Solid tiled roof: £6,100 to £15,000
These are indicative national figures. Prices in the South East are often 10 to 20% higher. So always get written quotes.
Is a solid tiled roof worth the cost?
A solid tiled roof pushes the conservatory roof replacement cost up the most. However, it brings real benefits. It insulates far better than glass, so the room stays warmer in winter and cooler in summer. As a result, you can use it all year round. A tiled roof can also add value to your home.
There are downsides too. Solid roofs let in less light. Many owners add LED downlights for about £300 to £600, or a roof lantern for roughly £800 to £2,000. A tiled roof also needs building regulations approval.
What about a glass conservatory roof?
Glass is the budget-friendly way to keep a light, bright room. It costs less than tiles, and self-cleaning solar-control glass is common. However, glass insulates less well. Without solar-control glass, the room can overheat in summer.
How long does a conservatory roof replacement take?
Most jobs take two to five days on site. A polycarbonate roof can take just one to two days. A tiled roof usually takes three to five days. Weather can add time, so plan some flexibility.
Do you need permission to replace a conservatory roof?
Planning permission is usually not needed for a like-for-like swap with the same size, height and position. Listed buildings and conservation areas are exceptions. However, building regulations approval is needed in England when you replace a glass or polycarbonate roof with a solid tiled roof. Ask every installer whether building control fees are in the quote. You can read more on the Planning Portal.
How to keep your conservatory roof replacement cost down
First, compare at least three written quotes. Next, check what each one includes, such as scaffolding, waste removal and VAT. Also, choose the roof for how you will use the room, not just for price. Finally, pick an installer who handles building regulations for you.
