How much does an orangery cost in the UK 2025?

It’s hard not to be drawn in by the allure of an orangery. They combine traditional, elegant design with modern architecture providing extra living space that’s attractive, cosy, and awash with natural light.

But how much does an orangery cost, and what are the key factors that affect the price of this stylish home upgrade? You’ll find all the important details in this handy cost guide.

What is an orangery?

An orangery is a hybrid between a full extension and a conservatory, often made of brick or stone and characterised by plenty of glazing. They typically have:

• Brick pillars flanking each window or door set
• Large windows
• A glass roof, lantern, or skylight

Thanks to the glass walls and ceiling, orangeries offer lots of light and are usable all year round.

They are an investment that can add a wow factor to your home and increase the value of your property.

Average cost of an orangery in the UK

The average cost of an orangery (16m²) tends to sit around £32,500.

This cost is for the complete project, including building and supplying the orangery structure, internal electrics, plastering, lighting, and all associated labour costs.

How much does an orangery cost per square metre?

As a guide, here’s what you can expect to pay, on average, for the supply and build of an orangery per m²:

• A hardwood orangery typically costs around £2,500 per m²
• A uPVC orangery tends to cost in the region of £1,200 per m²
• Aluminium orangeries come in at around £2,100 per m²

Typical cost for different size orangeries

The larger the orangery you opt for, the higher the cost. The average costs for supplying a hardwood structure for your orangery are:

• A small orangery (4m x 4m) will cost in the region of £5,000 – £11,500
• A medium-sized orangery (6m x 6m) typically costs between £12,000 – £30,000
• A large orangery (7m x 7m) tends to sit around £18,000 – £100,000

NB. These guide prices are for supply only. They exclude labour, fittings, design, features and fittings, windows, and doors.

Factors affecting orangery prices

Orangeries are often bespoke structures, therefore, several factors can affect the price you’re quoted. These include:

• Size and shape – The larger the orangery, the more you’ll pay for materials and labour. Bespoke designs, unique shapes, or complex builds can also push the price up
• Materials – Timber is a popular choice offering excellent insulation and a classic look. There’s low-maintenance and UV-resistant uPVC on the cheaper end of the spectrum. Aluminium is a pricier option, favoured for its durability and modern aesthetic
• Roof type – The type of roof you opt for – flat, lantern, or fully glazed – will impact the look and the cost of your orangery
• Additional features – The type of heating, plumbing, and electrics you select; the type and quality of fixtures and fittings, and the insulation and glazing options you choose will all impact the bottom line
• Location and labour – Prices will vary depending on where you live in the UK and the extent of the excavation or other prep work needed

Types of orangery

As we touched upon earlier, the material structure you choose will directly affect the cost of your orangery:

uPVC orangery

Very easy to maintain, resistant to UV light, and usually comes with a 10-year guarantee. uPVC orangeries are one of the most popular options in the UK.

uPVC orangery average costs (for supply and build):

• A small uPVC orangery (4m x 4m) costs around £25,000 
• A medium uPVC orangery (6m x 6m) costs around £40,000 
• A large uPVC orangery (7m x 7m) costs around £50,000 

Timber frame orangery

Often a choice of softwood or hardwood for the glass frame, the latter being more expensive but has a longer lifespan. Softwood is usually painted, while hardwood tends to be varnished. Wood frames are one of the best insulation materials for windows.

Timber orangery average costs (for supply and build):

• A small hardwood orangery (4m x 4m) costs around £50,000 
• A medium hardwood orangery (6m x 6m) costs around £80,000 
• A large hardwood orangery (7m x 7m) costs around £120,000 

Aluminium orangery

Although aluminium structures are available, composite framing tends to be more popular, combining wood and aluminium – with a lifespan of up to 85 years. The aluminium protects the outside from the elements, and the inner timber layer provides effective insulation.

Aluminium orangery average costs (for supply and build):

• A small aluminium orangery (4m x 4m) costs around £40,000 
• A medium aluminium orangery (6m x 6m) costs around £65,000 
• A large aluminium orangery (7m x 7m) costs around £90,000 

Orangery vs a conservatory or extension

Many homeowners are keen to know how orangery prices compare with that of a conservatory or a full extension. As a guide:

• The average orangery can range from £30,000 – £35,000
• A conservatory tends to cost in the region of £9,000 – £18,000
• A small, single-storey extension can cost anywhere from £40,000 – £56,000

Orangery cost vs conservatory cost

The cost of adding an orangery may be higher than a standard conservatory, but it generally tends to offer more functionality and have a bigger impact on property value. Orangeries are also more energy efficient on the whole, thanks to their sturdier structure.
