Note that pricing can also change considerably depending on the type of conservatory you have.
It’s also important to remember that conservatory roofing tends to deteriorate over time – from leaks to draughts to discolouring – which will, unfortunately, lead to maintenance costs. One way to overcome this is to get a solid conservatory roof.
For reference, a solid conservatory roof is not made of glass or polycarbonate, but instead uses tiles or a solid surface.

What is the cheapest material for a conservatory roof?
Your cheapest option is polycarbonate, a common material used in conservatory roofs. Its low production cost has made polycarbonate a popular choice. Still, its drawbacks need to be considered – poor thermal and sound insulation, short lifespan (around 10 years), and a tendency to discolour after exposure to the elements.
The second cheapest is glass, although, depending on the size of your conservatory and what level of glazing you choose, glass can become expensive. However, the benefits are numerous. You’ll get much better insulation (sound and heat), increased energy efficiency and you’ll get clearer views (polycarbonate is typically clouded).
Last, there are tiled conservatory roofs, which are the most expensive. Tiled roofs have some of the most substantial benefits, including lower maintenance, high durability, and the best insulation levels.
The cost of a replacement polycarbonate conservatory roof
Polycarbonate is the cheapest option for conservatory roof replacement. Although this material is not so popular, mainly because of its lack of eco-friendly credentials and the fact it tends to let less light in.
The price of a new polycarbonate conservatory roof is around £6,300 for a standard 3,000mm by 3,500mm lean-to conservatory.
Costs will depend on the size and type of conservatory, so check out the table below for a better idea of prices.
| Type of conservatory roof | Size of conservatory | Average price |
|---|---|---|
| Lean-to conservatory | 3,000mm x 3,500mm | £6,300 |
| Lean-to conservatory | 3500mm x 3500mm | £7,350 |
| Victorian conservatory | 4000mm x 4000mm | £9,600 |
| Victorian conservatory | 4500mm x 4500mm | £12,150 |
| Edwardian conservatory | 4000mm x 4000mm | £9,600 |
| Edwardian conservatory | 4500mm x 4500mm | £12,150 |

The cost of replacing a glass conservatory roof
Glass is the most popular conservatory roofing material in the UK due to its affordability. A new glass conservatory roof costs around £9,450 for a standard 3,000mm by 3,500mm lean-to conservatory.
Specialist glass panels, including energy-efficient and self-cleaning glass, are also available, but this will cost extra. You might find the expense worth it in the long run, as they can help you save on energy bills.
| Type of conservatory roof | Size of conservatory | Average price |
|---|---|---|
| Lean-to conservatory | 3,000mm x 3,500mm | £9,450 |

The cost of replacing a conservatory with a solid roof
A solid roof can refer to either a tiled or panelled roof. Tiles are lightweight and can add a traditional look to your conservatory, while solid panels can create more of a contemporary look.
The average cost for a standard solid conservatory roof replacement is between £7,000 and £20,000. But, as you can imagine, this price tag will vary widely depending on the size and type of conservatory you have and the material you go for.
And don’t forget to factor in the cost of plastering the interior. This is carried out to give you a nice finish to the ceiling. Although solid roofs tend to be more expensive than alternatives, they’re 15 times more thermally efficient than old glass or polycarbonate roofs.
By replacing a glass or polycarbonate roof with a tiled roof, you’ll be changing the classification of your conservatory from a ‘temporary’ to a ‘permanent’ extension. You should consult your local authority’s building control department to check whether you need to apply for planning permission.
Do I need planning permission to put a solid roof on a conservatory?
You do not usually need planning permission to replace a roof on an existing conservatory. A conservatory is a ‘permitted development,’ meaning you can replace the roof or make any aesthetic changes.
However, if you’re increasing the size of your conservatory, you’ll need planning permission. Even where you don’t need planning permission, you should allow neighbours to object to changes using the Neighbour Consultation Scheme.If you’re unsure whether you need planning permission, it’s always a good idea to contact your local planning office or look at the Planning Portal website.
How to get the best price for a replacement conservatory roof
- Compare at least three quotes to ensure you get the best price
- Compare local and national installers to see the difference in their products and prices
- Get quotes in writing and make sure they include all costs
- Don’t always choose the cheapest option – the quality and energy efficiency rating of the roof will save you money in the long run
- Make access to your conservatory easy – if it’s challenging to get to your conservatory, installation companies will quote more for the inconvenience
All you have to do is answer a few quick questions about your home and let us do the hard work. We’ll pass this information on to our suppliers, who will then provide free quotes for you to compare.
Can I get a conservatory roof replacement on finance?
Yes, most roofing companies allow this, and it can be a great way to spread the cost over several months or years.
Some companies also offer a discount if you pay monthly over 12, 24, or 36 months through a finance scheme.
Be aware, though, that using finance options usually means paying interest, which means your roof replacement might cost you hundreds or even thousands more than if you paid for it upfront.
How to choose the right conservatory roof installer
- Check they’re a member of The Conservatory Association – This is a division of the Glass and Glazing Federation (GGF), which promotes technical and health and safety standards, and protects homeowners when buying glass and glazing services.
- Check if the company is registered with Fensa (Fenestration Self-Assessment) – Fensa ensures that your conservatory is energy efficient. You may even need a Fensa certificate to comply with specific building regulations.
- Compare quotes – There are excellent national and local installation companies that can help you, but shop around for the best deal. Typically, you should compare at least three quotes during your research – although you can speed up the process by filling out this form. We’ll pass your information on to our suppliers, who will provide free quotes for you to compare.
