What Is the Average Cost to Replace a Conservatory Roof in the UK?
The average cost to replace a conservatory roof is around £10,000. Roofs typically cost anywhere from £4,000 to £18,000. The key cost factors that affect the price are the type of material which is used, the roof size, and the type or level of work which is carried out.
What Factors Affect the Cost of a Conservatory Roof Replacement?
1. Roof Material
This is the biggest cost driver, as roof material can vary widely in price. For example, a solid or tiled choice could cost five times more than a polycarbonate option.
2. Shape and size of the conservatory
A bigger conservatory will have a bigger roof. The bigger the roof the bigger the amounts of material used, which results in a bigger cost of labour.
Meanwhile, more complex designs, such as a Victorian roof or a P-shaped roof, have a higher cost compared to less complex designs.
3. Structural Upgrades
As well as the actual roof, renovations to your roof structure may be required to make the replacement possible and to comply with new laws. Example structural improvements are reinforced frames, new supports and work to meet building regulation upgrades.
Each bit of work needed will increase the final cost.
4. Insulation & Energy Efficiency
Improved energy efficiency will increase initial cost, but will have long-term positive impacts, including reduced energy bills.
Some example which could have an impact are: Thermal insulation, solar control glass, and ventilation systems.
5. Access & Installation Complexity
Limited access to a roof can make for complications such as requiring scaffolding, can increase overall labour costs.
Cost of Conservatory Roof Cost by Roof Type
The biggest factor affecting the cost of a replacement is the type of material you choose, the size of your conservatory and the different conservatory roof types.
Each material comes with different price points, insulation levels and longevity, while the complexity of a design will also have an impact on price.
In this section, we will cover different types of conservatory roof designs and conservatory roof materials.
Conservatory Roof designs
A few common types of design are:
- Lean-to conservatory: Arguably the simplest type of conservatory roof, this features an angled slope away from a home. For a limited space and a limited budget, this is a fantastic choice.
- Victorian conservatory: A classic style with a pitched roof and ornate roof ridge, this is a more complex design. This style is likely to be in the medium price bracket.
- Edwardian conservatory: A design more on the expensive side, this is similar to a Victorian option, but is a rectangular shape and features a flat front of the roof.
Polycarbonate Conservatory Roof Replacement Costs
Polycarbonate is a type of transparent, lightweight plastic that is ideal if you’re replacing like-for-like and don’t want to spend too much.
Prices can wildly vary, depending on the quality of the polycarbonate, the complexity of the project and the resulting labour costs.
Typical roof prices cost between £2,500 and £8,000, or £175 per m² and £800 per m².
Best for: Budget replacements
Pros:
- Cheapest option
- Lightweight and quick to install
Cons:
- Poor insulation
- Noisy in the rain
- Shorter lifespan
Glass Conservatory Roof Costs
A popular mid-range choice for UK homes, a glass roof will typically cost between £6,000 and £15,000, with a typical cost of £600-£1,200 per m².
Best for: Bright, modern spaces
Pros:
- Excellent natural light
- Longer lifespan
- Better insulation than polycarbonate
Cons:
- More expensive
- Can still overheat without solar control glass
Solid/Tiled Conservatory Roof Costs
In 2026, a conservatory with a solid or tiled top is one of the UK’s most popular choices. This will be around £600-900 per m², and overall will likely start at a base level of £6,000, with some projects costing over £16,000.
Best for: Year-round usability
Pros:
- Excellent thermal efficiency
- Reduces heat loss and noise
- Feels like a true extension
Cons:
- Highest cost
- May require structural checks or planning permission
Polycarbonate vs Glass vs Solid/Tiled Comparison
| Material | Cost | Lifespan | Insulation | Best For |
|---|---|---|---|---|
| Polycarbonate | Between £2,500 and £8,000 | 10-25 years | Poor | Budget replacements |
| Glass | Between £6,000 and £15,000 | 20-50 years | Good | Bright, modern spaces |
| Solid/Tiled | Start at £6,000 with some possibly over £16,000 | 40-60+ years | Excellent | Year-round usability |
Conservatory Roof Replacement Labour Costs
Labour typically accounts for a significant portion of the cost.
Depending on the size and difficulty of the project, prices can range between £300 and £500 per day per installer.
Most roof replacements take 2-5 days, depending on complexity, so overall labour costs are likely to be at least £1,000, and in some cases over £4,000.
Planning Permission & Building Regulations
In many cases, work falls under permitted development. Permitted developments are projects/developments to homes that don't require planning permission, allowing homeowners to perform certain renovations, such as conservatories, extensions, loft conversions, and outbuildings. These projects must follow strict size, height, and material rules, and primarily apply to detached, semi-detached, and terraced houses
However, you may need planning approval if:
- You’re converting to a stone or solid roof
- Structural changes are required
Prior to a roof replacement, always check details with your local authority or installer.
Additional Costs of Replacing a Roof to Consider
When budgeting, don’t forget additional costs including:
- Scaffolding: £390-£1,500 per week.
- Insulation upgrades: £500-£800
- Roof windows or skylights: £300-£2,600
- Electrical work (lighting): £200-£3,000+
These extras can significantly affect your final quote, but they vary depending on the project and the specification.
How Long Does a Conservatory Roof Replacement Take?
The time required to replace a conservatory roof depends on the size and complexity of the project, as well as the type of roof being installed.
For a standard conservatory, most replacements are completed within 2 to 5 days. This typically covers the removal of the existing roof, any necessary structural adjustments, and full installation of the new materials.
For larger or more complex conservatories, such as those with unusual shapes, bespoke glazing, intricate framework, or large structural changes, the process generally takes between 1 and 2 weeks.
It's worth noting that factors such as weather conditions, access to the site, and the lead time for specialist materials can also influence the overall timeline. Your installer should be able to provide a more accurate estimate once they've surveyed your conservatory in person.

What is the Cheapest Time of Year to Get a New Roof?
Conservatory roof installers tend to be busiest during the spring and summer months, which can push prices up due to higher demand. Booking your replacement in the autumn or winter, when the quieter season sets in, is often the smartest way to secure a better deal, as many installers offer more competitive rates to keep their schedule full.
It's worth bearing in mind, however, that colder and wetter weather can sometimes affect the installation process, so your project may take a little longer to complete than it would in the warmer months.
-
