Conservatory Prices 2025

On average, a conservatory in the UK costs around £20,000 to £30,000+ to build, with the average working out to be around £25,000, based on modern requirements.

The cost of your conservatory will largely depend on a number of factors about your build, including:

• Size
• Style
• Roof type
• Materials
• Windows, floors & doors
• Additional extras

So, the question of “how much will my conservatory cost” isn’t a simple answer – it involves identifying what the priorities are for your new room, and making a few decisions regarding its build.

But that’s why we’re here – to help break down all of these cost considerations, and give you all the information to help you to decide what your conservatory budget should be.

Size

Size is one of the biggest influencers on how expensive your conservatory will be to build.

The bigger the footprint, the more materials, glazing and labour you’ll need, meaning that the price can quickly rise as a result.

But, above everything, how big the space is will hugely change the layout of your home – so it’s one of the most important considerations to make!

Here’s a quick size-and-cost guide for reference:

Size	Typical Dimensions	Best For…
Small	3m x 3m to 3.5m x 3.5m	Tight gardens or budget-conscious builds. Usually single-room use, such as a reading spot or breakfast space.
Medium	4m x 3m to 4m x 4m	A multipurpose room, such as a dining table or a small lounge, to add more space to the home.
Large	5m x 4m to 6m+ wide	Open-plan living spaces (but could require more structural reinforcements and planning permission).
Bespoke	7m+ width or wrap-around	Blending in with your home, acting like an extension. These are fully customised layouts, so prices will vary.

Of course, thinking about size also comes with various other considerations, such as heating or ventilation, roof structures, suitable foundations and whether or not you’ll need planning permission – all of which add to the cost.

Style 

Thinking of having a lean-to conservatory? Or looking for something a little grander, like a P-shaped design? 

The style you decide on for your conservatory will largely influence your price range. 

In order of least to most expensive, the types of conservatory styles you could choose between include:

• Lean-to

The simplest and most affordable option, a lean-to conservatory has a straightforward sloping roof that works well for modern homes.

• Edwardian

A square or rectangular footprint with a high-pitched roof, maximising internal space and offering a clean, symmetrical look.

• Georgian

Similar to Edwardian, Georgian conservatories have more decorative detailing and sometimes more elaborate roof structures.

• Victorian

Featuring a rounded or faceted front, ornate detailing and a steep roof pitch, a Victorian conservatory is great for adding character to your home.

• Gable-ended

Similar to Edwardian, gable-ended designs have a vertical front roof panel that creates a more dramatic, spacious feel inside.

• T-shaped

Combining a central projection with two side sections, a T-shaped conservatory makes a bold statement, which can be perfect for larger gardens.

• P-shaped

A P-shaped design is a combination of conservatory styles, creating two distinct areas, which is ideal if you want both a dining and relaxation space.

• Glass extension

A modern, high-end alternative to a traditional conservatory, glass extensions typically feature large window panels and an aluminium frame, yielding a very aesthetically pleasing look.

Still not sure? Our thorough guide on what type of conservatory is best can help you make your decision. 

Roof Type

Deciding which type of roof you want for your conservatory will also, naturally, affect the price. 

For example, a solid tiled roof would lead you to the top of the price range, while a polycarbonate roof is the most affordable option. 

Here’s a list of roof types from least to most expensive, so you can gauge how this will affect your overall conservatory cost:

• Polycarbonate roofing

The cheapest option, polycarbonate is lightweight and good for budget builds, but can often offer poor insulation, and doesn’t control noise easily.

• Standard glass roofing

This is more expensive than polycarbonate, but gives better insulation, light and aesthetic appeal.

• Solar control or self-cleaning glass roofing

This is a step up in cost due to the specialist coatings required and the improved comfort it provides.

• Lantern roof

A firm favourite due to its aesthetic appeal, lantern roofs are often used in orangeries and high-end builds. However, they’re more expensive due to the structural work required.

• Solid tiled or warm roof

Most expensive, this roof type offers the best insulation, making the conservatory feel like a true extension of the home.

Materials

The materials you choose for your conservatory will have a large impact on both the cost and the overall look and feel of the space. 

Each option comes with its own pros, cons and costings. Some of the types of conservatory materials you can choose from include:

• uPVC

Not only is uPVC the most popular choice, but it’s also the most affordable. uPVC conservatories are low-maintenance, energy-efficient and available in a range of different finishes (including wood-effect).

• Aluminium 

Slightly more expensive than uPVC but very durable, aluminium offers a modern and sleek design with slim, but strong, frames. This allows for larger panes of glass, meaning more natural light can flood in. 

• Timber

Perfect for more conventional properties or a build with a natural, traditional finish, timber offers excellent insulation. However, this comes at a premium cost and requires regular upkeep; the latter of which is why we here at West Midlands Double Glazing do not offer this service.

Windows, Doors & Floors

How the conservatory is designed is what makes the difference between a room that’s usable year-round and one that feels too hot in summer or freezing cold in winter – and also has a significant impact on the overall cost.

• Glazing

What type of glazing should you choose for your windows? While double (or triple) glazing can help to keep the warmth locked in your home in winter, solar-control glass is a modern alternative to reducing overheating in the summer. 

• Blinds

Whether you’re considering window blinds, roof blinds or both, blinds and shading options can, again, add up to more than you’d anticipate. 

• Floors

Wooden floors may feel a little chillier underfoot come winter, so insulating under the base could be a good way to keep heat locked in. Underfloor heating or specialist glazing upgrades can create a more comfortable, warmer environment in winter.

Also, will you opt for luxury vinyl flooring? Or perhaps laminate? These types of flooring choices can often cost more than expected if not accounted for in the initial budget.

• Walls

Similarly, insulation within the walls can help to maintain heat in your conservatory during the colder periods. 

• Doors

Choosing what type of doors you’d like for your conservatory can also affect the cost. For example, whether you choose bi-folds or French doors, patio doors or a swing and slide, doors can affect how cool or well-heated your conservatory is, while also affecting the overall price.

Additional Extras

So, you’ve got a rough idea of what you want for your conservatory overall – what about the added extras that can quickly increase your total cost?

• Electrics

How many plug sockets will you need? What about wiring for overhead spotlights or a statement light, like a chandelier? Giving some serious consideration to your requirements of the room beforehand will allow you to get a more accurate feel for the budget.

• Heating & cooling

Radiators, underfloor heating or even air conditioning may be needed for year-round comfort – so it’s important to consider these in your budget from the get-go.

• Ventilation

Roof vents or trickle vents can help with airflow, but aren’t always included in basic quotes – so it’s important to consider what type of ventilation you’ll require.

• Built-in storage

Do you want a custom storage solution built into your build, such as pull-out drawers or shelves? All of these finishing touches will contribute to the overall cost, so it’s best to consider them early.

• Foundations

Every conservatory needs a solid foundation, and the cost can vary depending on your property. If your garden has clay-heavy soil, uneven ground or is close to large tree roots, the foundations may need to be deeper and more reinforced. In some cases, drainage work is also required to avoid issues with damp or subsidence in the future.

• Building regulations

Not all conservatories need to meet building regulations, but in many cases they do – especially if you want the space to function as a proper extension of your home. Building regulation approval ensures the conservatory is safe, energy-efficient and structurally sound.

• Planning permission

Smaller conservatories often fall under “permitted development rights,” meaning you may not need planning permission. However, this depends on the size and height of the structure and other factors. If planning permission is required, there will be extra costs and a longer timeline to consider, so it’s worth checking early in your project. Our guide on “do you need planning permission for a conservatory” can give you more information.
