Note: The following tables show potential costs for a uPVC conservatory with a glass roof. Using clear polycarbonate for roofing as an alternative to glass often reduces costs by £1,000 – £1,500. Choosing a frame made from aluminium or wood will also increase the cost of your conservatory.

Average Cost of a Conservatory by Style

In very broad terms, the average mid-range conservatory costs between £12,000 – £15,000. However, there's a lot more to it than that, as they can cost as little as £5,000 or as much as £20,000 – £30,000. The cost of your new conservatory will largely depend on the size and type of conservatory that you want, as well as:

  • The type of roof
  • The type of glazing
  • The frame material
  • Any groundwork or extra labour required.

Lean-to Conservatory Prices

 Lean to Conservatory

Lean-to conservatories are very popular because they are often more affordable for homeowners wishing to keep costs to a minimum. These conservatories have a roof which leans down into 3 walls of the conservatory. This conservatory is simple in structure which means installation is both quicker and less costly. Lean-to conservatories can be added to any style of property (even smaller terraced homes) or as part of an extension.

Size of Lean-to Conservatory Average Price with Dwarf Wall Average Price Fully Glazed
3.5 x 2m £7,500 – £8,500 £6,500 – £7,500
3.5 x 2.5m £8,500 – £10,000 £7,500 – £9,000
4 x 2m £8,000 – £9,500 £7,000 – £8,500
4 x 2.5m £9,500 – £10,500 £8,500 – £9,500

Gable Conservatory Prices

Gable Conservatory

A Gable conservatory offers a grand, elegant and sophisticated look which incorporates a particularly large roof so a dwarf wall is usually required to support its weight. For this reason it's most commonly installed on high roofed properties. The Gable's high ceilings are perfect for maximising the feeling of open space and for letting as much light as possible into the space.

Size of Gable Conservatory Average Price
3.5 x 3.5m £12,500 – £14,000
3.5 x 4m £13,500 – £15,000
4 x 4m £14,500 – £16,000

A Victorian conservatory, as you might expect, is styled like structures of the 19th century with decorative finishes and a steep roof.

Size of Victorian Conservatory Average Price with Dwarf Wall Average Price Fully Glazed
3.5 x 3.5m £12,000 – £13,500 £10,500 – £11,500

4 x 4m £13,500 – £15,000 £12,000 – £13,500

3.5 x 3.5m £9,500 – £11,000 £8,500 – £9,500

3.5 x 3.5m £13,000 – £15,000
3.5 x 4m £14,000 – £16,000

Orangery Prices


Originally used to grow citrus fruits, orangeries have grown considerably in popularity in recent years as an alternative to conservatories. Rather than glass panes as walls like a conservatory, an orangery has solid walls like a normal extension, but with a glass lantern in the centre of the roof. It's essentially a combination of a sun-room in the summer and an extension which retains more warmth during the winter.

An orangery is the hardest cost to estimate as prices can range from £20,000 up to as much as £80,000, but the following table gives some general pricing guidelines for an orangery projecting 3m from your existing home.

Width of Orangery Approximate Price Range
4m £24,000 – £26,000
5m £29,000 – £32,000
5.5m £33,000 – £36,000
6m £37,000 – £41,000
6.5m £39,000 – £43,000
7m £42,000 – £47,000
8m £48,000 – £53,000

Do You Need a Dwarf Wall?

You will need to choose whether you want the walls of your conservatory to be entirely glazed from top to bottom or if you want to include a dwarf wall at the bottom. A dwarf wall is a brick wall about a metre high which provides a stronger base for the conservatory's frame. A dwarf wall will increase the cost of the conservatory but is a very popular option as it can improve the frame's strength (particularly important if you're using a heavy roof material) as well security and insulation.

Cost of Conservatory Frame Materials

The frame is the structure which sits on the ground or dwarf wall, holds the glass panes in place and supports the roof. In most cases your conservatory's frame will be constructed in either uPVC, aluminium or wood and this will have a direct impact on the cost of your conservatory. For example, a 3.5 x 3.5m lean-to conservatory in uPVC could cost between £8,500 – £11,00 on average, while the wooden equivalent could be as much as £12,000 – £14,000.

uPVC Conservatories

A uPVC conservatory is the cheapest option and is also the easiest of the 3 materials to maintain. Although in the past uPVC has had a reputation for fading and warping there has been a lot of improvement in the manufacturing process and good quality uPVC offers great durability.

Aluminium Conservatories

If longevity and strength are priorities for you the aluminium may be a good investment. Slightly more costly than uPVC but longer lasting and weatherproofed. Aluminium (and uPVC) can be produced in a range of colours to suit your home.

Wooden Conservatories

A wooden frame offers arguably the most attractive finish and is often the preferred choice for traditional properties. The issue with wooden frames is that the cost is often higher and they require maintenance every few years to keep them in good condition and protect them from the elements.

Types of Conservatory Glazing

The sides of your conservatory will be made up of double or triple-glazed glass panes. These are 2 or 3 panes of standard (annealed) glass with argon gas between each pane to improve insulation. However, you may also want to ask your installer about the following options which will add around 20-40% to the cost of your double-glazing.

Low E Conservatory Glass

This glass has been coated in a thin layer of metal designed to keep your conservatory cooler in the summer and warmer in the winter.

Self-cleaning Conservatory Glass

This glass is coated in titanium dioxide which means it lets slightly less light into the space (although this is rarely noticeable) but will reduce how often you need to clean your windows. When UV rays from the sun and water in the atmosphere combine on the glass they react and breakdown dirt which has gathered on the window.

Noise Reducing Conservatory Glass

For homes in busy areas noise control or noise reduction glass could be a lifesaver as it could reduce the amount of noise pollution entering your conservatory significantly.

Toughened Conservatory Glass

Toughened or tempered glass might be a good option if you're concerned about security as it's incredibly strong. In addition, it has a safety feature as it's been specially treated to ensure that if broken it shatters into small pieces rather than into large shards. You could also use laminated glass which has been covered by plastic on both sides which keeps broken glass in place.

Decorative Conservatory Glass

It's also possible to use coloured, stained or etched glass in your conservatory glazing to make it unique to your home and tastes.

Conservatory roof

Cost of Conservatory Roof Materials

The material for your conservatory roof needs to be compatible with your choice of frame and dwarf wall (if you need / want one), i.e. it can't be too heavy. In addition, the material used will also affect how much light enters the space as well as both heat and noise insulation properties.

Glazed Conservatory Roof

The main benefits of using glass panes in your roof are that it lets maximum sunlight through and it also has great insulation properties against both heat loss and noise. The most popular choice is double-glazing but a potential drawback is that double or triple glazed roofs can make conservatories too hot in the summer because they're such good insulators. Also, heavy rain on the glass roof can be very loud.

However, as with the sides / windows in your conservatory, you can choose to use a treated type of glazing to help with temperature control and noise reduction.

Polycarbonate Conservatory Roof

Polycarbonate sheets are visually very similar to glass but are a much cheaper alternative. They are also quicker and simpler to install as they're more lightweight. However, polycarbonate will not provide the same insulation so you may find the conservatory too cold to use in winter.

Tiled Conservatory Roof

Although a tiled roof is usually more costly and will take longer to install it often acts as a better insulator of heat and against noise. You will lose sunlight with a tiled roof but skylights or rooflights are an option to counteract this.

Conservatory Flooring

Cost of Conservatory Flooring

Another factor to consider when costing your new conservatory is the flooring. Here are a few options to think about, from the cheapest to the most expensive, with some of their main pros and cons.

Carpeted Floor

You may choose to carpet your conservatory which is definitely the cheapest option, and it could give the space a cosier feel. Like any carpets in your home it requires the usual vacuuming and occasional cleaning, but beware that carpet exposed to sunlight tends to lose its colour.

Laminate Floor

If you want the look of wooden flooring without the high price tag, you may want to look at a laminate floor. It can be very convincing in terms of giving that real wood look, but it can be easily damaged and can warp over time.

Tiled Floor

Tiled conservatory floors are very popular as they are so versatile in terms of colours, finishes, patterns and shapes. Tiles are also easy to keep clean so are a great option for low maintenance. Some homeowners find that tiles are cold to walk on during winter; if this is a concern for you, then underfloor heating could be a solution.

Wooden Floor

A wooden floor is definitely a great way to add that luxurious finish to your conservatory, but it is pricier than other flooring types. In addition, as the temperature in your conservatory increases and decreases the wood may expand and contract which can lead to issues.

How Much Does Conservatory Installation Cost?

In addition to the cost of all the materials for your conservatory you'll also need to factor in the cost of the installation. Labour costs will vary depending on how much ground preparation work is needed and whether you're incorporating any extras such as underfloor heating.

You'll also find that different companies will provide different quotes so it really pays to shop around and compare before settling on a price. The best way to save money on the cost of your new conservatory is to get quotes from at least 2 or 3 different suppliers. You can then see where you're getting the best value for your money and take a look at previous customer recommendations to make sure you're choosing a reputable and professional company.
