Conservatories are a cherished part of UK homes, providing a bright, airy space that bridges the indoors and out. But for many homeowners, their practicality can vary dramatically with the seasons. Too cold in the winter, unbearably warm in the summer, and increasingly expensive to heat or cool due to rising energy costs. It’s no surprise, then, that conservatory roof conversions have surged in popularity as homeowners seek to boost comfort and efficiency while transforming the space into a year-round living area.
If you’re considering upgrading your conservatory, you’re likely wondering about costs, options, and whether it’s worth the investment. This blog will break everything down for you – from conversion types and associated costs to hidden expenses and when it truly makes financial sense.
What is a conservatory roof conversion?
Before jumping into costs and options, it’s important to understand what a conservatory roof conversion entails.
A conservatory roof conversion involves replacing the existing roof – typically made of glass or polycarbonate – with an upgraded material such as solid tiles, hybrid designs, or improved glass panels. The goal is to enhance insulation, regulate temperature, and improve the look and usability of the space.
Common motivations for a roof conversion include:
- Improved insulation to tackle energy inefficiency and reduce heating bills.
- Temperature regulation, ensuring the conservatory feels comfortable year-round.
- Boosted aesthetics, modernising the look and feel of the space.
- Increase in overall property value, especially when fitted with premium designs.
Materials used in roof conversions:
- Polycarbonate – Lightweight and budget-friendly but poor at insulation.
- Glass – A step up for temperature regulation, with varying quality grades.
- Solid tiles – Exceptional for insulation, offering the feel of a “full room addition”.
- Hybrid/lantern roofs – Combines insulation with natural light for a premium look.
Types of roof conversions and their costs (UK average prices)
Costs for conservatory roof conversions vary widely depending on the type of upgrade you choose. Here’s a breakdown of the most common options and what you can expect to pay.
Polycarbonate to glass
Average cost: £2,000–£4,000
This is one of the more budget-friendly upgrades. Glass roofs offer improved insulation compared to polycarbonate, as well as better noise reduction during rainfall. Although it’s a significant improvement, glass options may still struggle with extreme weather conditions.
Pros:
- Affordable for small- to medium-sized conservatories.
- Provides better visibility and a brighter space.
Cons:
- Can still lose heat quickly during colder months.
- Requires regular cleaning and upkeep.
Glass to tiled/solid roof
Average cost: £4,000–£7,000
Upgrading to a tiled or solid roof represents a mid-to-high elevation in terms of both cost and impact. These conversions significantly enhance insulation and may allow for the installation of ceiling lights. The space will begin to feel more like an extension of your home rather than a conservatory.
Pros:
- Exceptional climate regulation and comfort.
- Increased energy savings.
Cons:
- Tiled roofs may reduce natural light unless skylights are added.
Hybrid or lantern roofs
Average cost: £8,000–£12,000+
For homeowners seeking complete luxury, hybrid or lantern-style roofs combine the benefits of solid insulation with feature glass panels or overhead skylights. These designs are visually stunning but come with premium pricing.
Pros:
- Modern, luxurious aesthetics that elevate the property.
Balance of light and insulation.
Cons:
- Hefty investment required, suited primarily to high-budget projects.

Resale Value: Premium – boosts overall home appeal
Hidden & ongoing costs to consider
Structural reinforcements
Older conservatories may require additional structural support to bear the weight of a tiled or hybrid roof. Labour and material costs for reinforcement can add several hundred to over £1,000 to your budget.
Planning permissions
Most conversions fall under permitted development rights, but specific designs or heritage properties may require planning permission, costing £200–£500 on average.
Ventilation and lighting upgrades
Switching to a solid roof might reduce airflow or natural light. Many homeowners resolve this by adding skylights, ceiling fans, or upgraded ventilation systems – all of which carry additional costs.
Heating options
If your conservatory is being used as a proper living space, installing underfloor heating or a modern radiator may be worth considering. This can cost anywhere from £500 to £2,000 depending on your heating method of choice.
What impacts the total cost?
The following factors play a significant role in determining your overall conservatory roof conversion cost.
Conservatory size
Larger conservatories naturally require more material and labour, adding to total costs.
Existing structure condition
Poor structural health may necessitate repairs or reinforcements before proceeding with the conversion.
Roof style chosen
High-end designs like hybrid roofs and lanterns generally have higher material and labour costs.
Is a roof conversion worth it?
Ultimately, the decision to invest in a conservatory roof conversion depends on your objectives and budget. For many homeowners, the benefits significantly outweigh the costs, including year-round comfort, lower energy bills, and enhanced property value.
When a conversion makes the most financial sense:
- You’re intending to stay in your home for several years and want to maximise comfort.
- You’re looking to make a poor-performing conservatory usable once again.
- The conversion will help improve energy efficiency in the face of escalating energy prices.
