What's In This Guide?



1. How Much Does a Replacement Conservatory Roof Cost?

Your new conservatory roof replacement cost will be between £2,355 and £5,570, depending on your roof type, and material. A glass roof will be cheaper than a tiled roof, for example, because the job is less labour-intensive, and a solid construction may require pricier structural work.

Conservatory roofing deteriorates over time, from leaks and draughts to discolouring. But you may also just want to change the look of your extension by replacing the roof with new glass or a solid/tiled structure that’ll better retain heat.

There are many companies in the UK that can help to transform your conservatory, but how much will the work cost you personally? We’ve researched the market to find different prices for different materials and conservatory types. See average conservatory roof prices in the below table:

2. Tiled Conservatory Roof Prices

Solid tiled conservatory roof

On average, you can expect your tiled conservatory roof to cost from around £4,000 for a smaller conservatory (anything below 4000mm x 4000mm), and up to £6,000 for a larger conservator (over 4000mm x 4000mm).

Of course, these cost estimates for a conservatory roof replacement with tiles will vary depending on where you live. Larger cities have more competition from suppliers, which bring the prices down. Plus, you can expect to pay more if you'd like to install Velux or roof windows into your roof.

On top of that, ask yourself what state your existing conservatory structure is in. Replacing your conservatory roof with a solid, tiled construction can make your seasonal garden room into an extension that can be enjoyed all year round, but changing the roof material can change the category of your conversion, which may require costly planning permissions.

What are tiled roof conservatory building regulations? Replacing a glass or polycarbonate roof with a tiled roof, you'll be changing the classification of your conservatory from a 'temporary' to 'permanent' extension. You should consult your local authority's building control department to check whether you need to apply - or reapply - for planning permission, which currently costs £462 in the UK.



3. Glass Conservatory Roof Cost

Glass conservatory roofs are the most popular roofing material in the UK. The price of a new glass conservatory roof starts from around £2,610 for a lean-to conservatory (sized 3000mm x 3500mm).

The table below shows the average price of a new glass roof for common types of conservatories in the UK:

Type of conservatory roof

£2,610 – £3,175

Specialist glass conservatory roof panels are also available, including energy efficient and self-cleaning glass. Specialist glass will cost more than standard glass, but you may find it's worth it. That's because energy efficient glass will help reduce your heating bills, giving you a return on investment within a few years.

If you're considering a glass conservatory roof, we recommend asking installers to also provide a quote for specialist glass, so you can see the difference for yourself.



4. Replacement Polycarbonate Conservatory Roof Cost

Polycarbonate conservatory roof panels are typically cheaper than glass roofs. However, they are much less popular, as they are less eco-friendly, and let less light in. Conservatory roof replacements from plycarbon also experience big differences in temperature in summer and winter.

Type of conservatory roof
Size of conservatory
Average price
Lean-to conservatory

5. Top 5 Tips to Get the Best Price on Your Replacement Conservatory Roof

Tip 1 - Compare at least 3 quotes. We recommend you receive at least 3 quotes to ensure you get the best price.

Tip 2 - Compare local and national installers. We recommend comparing at least 1 local installer and 1 national installer to compare the difference in their products and prices.

Tip 3 - Get quotes in writing and ensure it includes all costs, such as material.

Tip 4 - Don’t simply choose the cheapest price. You should consider the quality and the likely energy efficiency of the roof you have installed.

Tip 5 - Make access to your conservatory easy. An installation company will quote higher if access appears to be difficult to access your conservatory as it will take them longer to install the new roof.

6. Can I Get the Work Done on Finance?

Most conservative roofing companies offer finance plans for replacement conservatory rooves, helping you spread the cost over a number of months or years. You can always ask any company quoting for your new conservatory roof whether they offer a finance scheme.

Some companies offer a discount if you opt to pay monthly via a finance scheme provided by one of their third party finance providers. They offer a discount because the third party finance provider will pay them commission for your finance contract.

Typical time frames that you can spread payments across are 12, 24 or 36 months. However, beware that if they do offer a finance option with interest, it could mean the work will end up paying hundreds or thousands more than it should.



7. Do You Need Planning Permission to Put a Roof on a Conservatory?

The short answer is no. Whether your conservatory roof is solid, tiled or glazed, it now no longer needs planning permission, since a conservatory is classed as 'permitted development'. An extension, on the other hand, is not.

According to the government's Planning Portal website, conservatories - but not extensions - are exempt from planning permission. So, what's the difference? Your conservatory will need to be separated from your home using external walls, and run its own heating system.

But, even if you don't need planning permission for your roof replacement, single-storey conservatories of all sizes will need to give neighbours the chance to object to changes using the Neighbour Consultation Scheme.



8. Choose the Right Conservatory Roof Installer

1. Trusted? When choosing your conservatory roofing company, it's a good idea to 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.

2. Certified? You should also check if the company is Fensa (Fenestration Self-Assessment) registered. Fensa specialises in ensuring that your conservatory is energy efficient. You may even need a Fensa certificate in order to comply with certain building regulations.

3. Problem? If you encounter any issues during your roof replacement, you can contact the Conservatory Ombudsman (DGCOS), who will help you resolve them.
