How Much Does a Conservatory Cost in 2026

A conservatory can provide valuable additional living space while bringing more natural light into your home. Whether you want a dining area, garden room, playroom or somewhere to relax, understanding the costs involved is an important first step.

There is no single price for a new conservatory, as the final cost depends on factors such as its size, style, materials, glazing and roof specification. As a general guide, a standard conservatory can cost anywhere from around £11,250 to £22,500, with larger or more bespoke designs requiring a greater investment.

To help you plan your project, we’ve explored the typical costs of different conservatory styles, what influences the overall price and which additional expenses you may need to consider.

How Much Does a Conservatory Cost?

The style and materials you choose will have a significant impact on the price of your conservatory. As an indication, the following estimates are provided by Check-a-Trade based on a 3.5m x 3.5m design:

These figures provide a starting point when comparing different designs and materials. However, your final quotation will depend on the individual requirements of your property, including groundwork, glazing and roof choices.

Before starting a conservatory project, it’s always worth speaking to local conservatory specialists. They can assess your property, discuss suitable options and provide an accurate quotation based on your requirements.

What Are the Different Types of Conservatory and How Much Do They Cost?

There are several conservatory styles available, each offering different benefits in terms of appearance, available space and cost. Three of the most popular choices in the UK are lean to, Victorian and Edwardian conservatories.

Lean To Conservatory Costs

Lean to conservatories are one of the simplest and most affordable designs. They feature three walls attached to the side of your home and traditionally have a sloping roof that sits neatly beneath the existing roofline.

Their straightforward design makes them particularly suitable for properties with limited garden space or lower rooflines.

A lean to conservatory typically costs between £11,250 and £17,813, depending on its size and specification. For a 3.5m x 3.5m design, you could expect to pay around £12,813 for uPVC.

Victorian Conservatory Costs

Victorian conservatories are recognisable by their rounded or faceted frontage, pitched roof and decorative appearance. They are a popular choice for traditional British homes, although their versatile design can also complement more contemporary properties.

The additional detailing and shape can make them more expensive than a straightforward lean to design. A Victorian conservatory typically costs between £15,000 and £21,875.

For a 3.5m x 3.5m conservatory, estimated prices are £15,938 for uPVC.

Edwardian Conservatory Costs

Edwardian conservatories offer a more understated alternative to Victorian designs. They feature a square or rectangular floor plan with a flat frontage, making it easier to maximise the available interior space.

Their practical layout makes them particularly suitable for homeowners who want to create a dining area or additional living space.

An Edwardian conservatory generally costs between £13,125 and £22,500. For a 3.5m x 3.5m design, prices are approximately £14,063 for uPVC.

Orangery Costs

An orangery combines elements of a traditional conservatory and a home extension, using a mixture of brickwork, solid construction and glazing. Its more substantial structure creates a different appearance and feel from a predominantly glazed conservatory.

Due to the additional building work and materials involved, orangeries generally cost more than standard conservatory designs. As a guide, a 16m² orangery costs approximately £40,625.

What Affects the Cost of a Conservatory?

While the style and dimensions provide a useful starting point, several other factors can influence the final price of your project.

The main considerations include:

Size of the conservatory: Larger designs require more materials, glazing and installation work, increasing the overall cost.
Style: More intricate designs, such as Victorian conservatories, can require additional materials and construction work.
Roof type: Glazed, tiled and solid roof systems have different costs and performance characteristics.
Materials: uPVC and wood offer different price points, appearances and maintenance requirements.
Ground preparation: Uneven ground, drainage requirements and additional foundation work can increase installation costs.
Glazing specification: The type and quality of glass will affect both the initial investment and the conservatory’s thermal performance.
Additional features: Extras such as underfloor heating, upgraded doors, lighting and electrical installations will add to the overall budget.

It’s also worth considering how you intend to use the space. Modern conservatory materials and glazing options can help maintain more comfortable temperatures throughout the year, addressing some of the issues associated with older conservatories that were often too hot in summer and too cold in winter.

What’s Included in a Conservatory Installation Quote?

When comparing conservatory prices, it’s important to understand exactly what is included in each quotation. A typical installation quote may cover:

Labour and installation.
Materials and conservatory components.
Groundwork and site preparation.
Removal and disposal of waste.
Design and planning requirements.

Always request a written quotation with a clear breakdown of the work involved. This will help you compare installers fairly and identify any additional expenses that may not be included in the initial price.

Additional Costs to Budget For

As well as the main conservatory installation, there may be some additional expenses to consider. Depending on your property and the scope of the project, these could include:

Extra ground preparation or structural work.
Additional waste disposal, site clearance or skip hire.
Scaffolding or other access equipment.
Parking fees or travel expenses.

You should also consider the longer-term upkeep of your conservatory. Regular cleaning, maintenance and occasional repairs or refurbishment will help keep the structure in good condition over time.

Planning Your Conservatory Budget

Before committing to a design, think carefully about your budget and what you want to achieve with the additional space. Consider the size and layout you need, the materials that best suit your property and whether you want features such as upgraded glazing or a different roof system.

It’s sensible to allow some additional money for unexpected work, particularly if your property requires more extensive groundwork or preparation than initially anticipated.

You should also check whether planning permission or Building Regulations approval applies to your proposed design. Some conservatories fall within permitted development rules, but restrictions can apply, particularly where structural alterations are involved. Your installer can help you understand what needs to be considered before work begins.
