If your conservatory is too hot in summer, freezing in winter, or simply noisy and inefficient, replacing the roof can be one of the most effective upgrades you can make. A modern replacement roof can dramatically improve comfort, energy efficiency, and the overall value of your home. But the most common question homeowners ask is: how much does a replacement conservatory roof cost in the UK?
The short answer is that prices vary widely. In 2025, UK homeowners typically pay anywhere from £2,000 to over £20,000, depending on several important factors. Below, we break down the costs in detail so you can understand what affects pricing and what to expect for your budget.
Average Replacement Conservatory Roof Costs in the UK
The cost of replacing a conservatory roof depends largely on the type of roof you choose. Each option comes with different price points, performance levels, and long-term benefits.
Polycarbonate replacement roofs
This is the most affordable option and is often chosen when budget is the main priority. Prices usually start from around £2,000 to £5,500 for a standard-sized conservatory. While polycarbonate roofs are lightweight and quick to install, they offer limited insulation and tend to be noisier during rain.
Glass conservatory roofs
Modern glazed roofs are a popular mid-range choice. Costs typically fall between £3,000 and £8,000, depending on the size and the type of glass used. Advanced glazing with solar control or self-cleaning coatings increases the price but greatly improves thermal performance and comfort.
Solid or tiled conservatory roofs
Solid replacement roofs sit at the premium end of the market. Prices usually start around £5,000 and can rise to £15,000–£22,000 or more for larger or more complex installations. These roofs transform a conservatory into a true year-round living space, offering excellent insulation, sound reduction, and a more “extension-like” feel.
What Affects the Cost of a Replacement Conservatory Roof?
Several key factors determine how much your replacement conservatory roof will cost.
Size of the conservatory
Larger conservatories require more materials and labour, increasing the overall price. A small lean-to conservatory will be significantly cheaper to re-roof than a large Victorian or P-shaped design.
Roof design and complexity
Simple roof styles are faster and cheaper to install. Complex shapes, multiple angles, or bespoke designs increase labour time and material costs.
Material choice and insulation level
Higher-performance materials cost more upfront but often deliver better energy efficiency. Insulated solid roofs, for example, can reduce heating bills and improve comfort throughout the year.
Structural work and reinforcement
Some conservatories require additional structural support, especially when upgrading from a lightweight polycarbonate roof to a tiled roof. Steel beams or reinforced frames can add to the total cost.
Labour and installation costs
Labour typically accounts for a significant portion of the price. Costs can vary by region, with higher prices often seen in London and the South East compared to other parts of the UK.
Is a Replacement Conservatory Roof Worth the Cost?
For many homeowners, the answer is yes. A replacement roof can:
• Make the conservatory usable all year
• Improve insulation and reduce energy bills
• Reduce noise from rain and wind
• Enhance the appearance of the property
• Increase overall home value
In particular, upgrading to a solid or insulated roof often turns a rarely used conservatory into a functional dining room, home office, or family space.
Planning Permission and Building Regulations
In most cases, replacing a conservatory roof does not require planning permission, provided the structure remains within permitted development limits. However, building regulations approval is often required, especially for solid or tiled roof replacements. A professional installer will usually handle compliance and certification as part of the project.
Final Thoughts
So, how much does a replacement conservatory roof cost in the UK? The realistic answer depends on your expectations, the size of your conservatory, and the level of comfort you want to achieve. While budget options can start from a few thousand pounds, higher-quality roofs represent a long-term investment in comfort, energy efficiency, and home value.
If your conservatory currently feels like wasted space, replacing the roof may be one of the most cost-effective home improvements you can make.
