How Much Does a Conservatory Cost?

The price of conservatory installation will vary depending on the material you use, as a wood costs around £5000 to £29,100. Other options include uPVC, which is typically priced at £3900 to £66,700, while aluminium ranges from £4000 to £73,800.


The type of conservatory you choose will also determine the final cost. There are various options to consider including:

Victorian

A Victorian conservatory is a traditional-style extension which has three to five sides and a high-pitched roof with decorated ridges. The average cost to install a Victorian conservatory ranges from £5300 to £18,500.

Edwardian

Another traditional style is an Edwardian conservatory which usually has a triangular or square shape. In comparison to a Victorian conservatory, it has a more minimal design with a flat front, although it does have the same style pitched roof. Edwardian conservatories tend to cost around £5300 to £17,700

Lean-to

The main characteristic of a lean-to conservatory is a flat angled roof which slopes downwards. This is ideal for houses which lack height or have limited space. Conservatory prices for a lean-to style are usually around £3900 to £20,000.

P-shaped

A P-shaped conservatory is a combination of a Victorian-style and lean-to conservatory which offers you more space than other conservatories. This type of extension tends to cost around £5700 to £15,400.

L-shaped

An L-shaped conservatory offers a mixture of styles including both Edwardian and lean-to conservatories. This is perfect for anyone looking to expand their home and add on multiple rooms. L-shaped conservatories range from £6900 to £19,000.

T-shaped

A T-shaped conservatory usually features a Victorian-style roof with a central projection point, which helps to create two living space within one extension. This type of conservatory costs around £6,800 to £19,000.

Orangery

An orangery is a type of extension which features a glass roof and walls that covers more than 50% of the extension. There are normally installed on smaller properties, as the allowance of natural light can significantly enhance the space. For a basic small conservatory cost is around £9,300 to £73,800 for a large premium orangery.

Sunroom

Sunrooms usually feature an opaque roof which does not allow as much sunlight in as typical conservatories. Some sunrooms do not feature any glass on the walls, although some designs do have some glass elements. Sunrooms normally cost around £13,300 to £60,000.

Glass room

A glass room is completely transparent from floor to ceiling as the roof and walls are made entirely of glass. This is ideal for enhancing exterior views and offers a contemporary design. Glass rooms tend to be priced at £2,400 to £16,800.

What are the Additional Costs of a Conservatory?

There are various other costs you need to consider when installing a conservatory, such as:

Extensive Conservatory Groundwork Costs

Before building a conservatory, it is important that the ground is fully prepared to support the new build. This could include excavation which involves digging up and levelling the ground to ensure it is secure. This normally costs around £30 to £50 per cubic metres to fully prepare the ground.


You may also need to check that you have proper drainage in place that is connected to the main water supply. If not, you may have to pay for drainage installation which involves a lot of digging and installation of pipework and drainage which normally costs around £700 to £1000.

Conservatory Planning Permission Costs

To adhere to planning permission regulations you need to make sure that your conservatory does not cover more than half the area of the existing property. It should also not be higher than the highest part of your property’s roof or eaves and should not extend more than four metres beyond the rear wall of your home.


If you plan to install your conservatory within two metres of the property boundary then the height of the eaves must not exceed three metres. The conservatory must not be brought in front of the principal elevation or side elevation if it is near a highway. The installation should also not include any raised platforms or any alterations to the existing roof.


If you plan to make any changes that are not permitted or you live in a listed building, then you will have to apply for planning permission which normally costs around £200.

Conservatory Building Regulation Costs

Before building a conservatory, it is important that you adhere to the extension building regulations that are currently in place. To ensure you meet building regulations, you should hire a tradesman listed under the competent person’s scheme. If you opt to hire someone who is not registered, then you may need to pay for building approval yourself, which will vary depending on your local council’s costs.


You must obtain building regulations approval for your conservatory doors and windows. This includes making sure that they are energy-efficient and that the recommended amount of heat that can pass through the glass is met. You will also need to make sure that safety glazing is used in critical areas where there is an unobstructed opening and any glazed door up to 1500mm from the ground.


Another important regulation involves ventilation, as you must ensure that all doors and windows provide appropriate ventilation especially if you are using your conservatory as a kitchen or utility room.


You also need to ensure that your conservatory is protected against fire, which could involve installing doors or windows with extra fire resistance. You should also make sure that they are big enough to provide a means of escape should a fire break out.


You may not have to apply for building regulations approval if your conservatory is less than 30 square metres, is separated from your home, and has its own separate heating system.

Conservatory Guttering Cost

To protect your conservatory, you will need to install guttering to prevent water from damaging the foundations. The cost of conservatory guttering is around £12 to £16 per metre.

Conservatory Blinds Cost

For added privacy for your conservatory, you should consider having blinds fitted to each window. There are different types of blinds including roman blinds which cost around £20 to £60, while venetian blinds are normally priced at £10 to £30. Another popular option is vertical blinds which range from £16 for plain styles and up to £100 for premium blinds.


For professional blind installation, you can expect to pay anywhere from £20 to £50 for conservatory blinds, although this will vary depending on how many windows you have.

Conservatory Heaters Cost

The problem with conservatories is that they can become cold in the winter. To ensure your conservatory stays warm, you can consider installing an electric radiator which normally costs around £100 to £150 to buy and install.


Another common conservatory heating solution is underfloor heating which is typically priced at £60 to £100 per square metre for professional installation.

What are the Supply Costs of a Conservatory?

If you are planning to install a new conservatory yourself or wish to buy your own supplies, then you should consider the following rough conservatory prices.

Type of conservatory
uPVC supply cost (m²)
Wood supply cost (m²)
Aluminium supply cost (m²)
Victorian £360 - £700 £760 - £1080 £440 - £820

Glass room £230 - £470 £570 - £650 £890 - £1200

Tradesmen Costs of a Conservatory

One of the most important costs you need to consider when calculating the installation of a new conservatory is the price of labour.


To ensure your conservatory is built to a high standard you should hire a team of professionals who will charge around £150 to £200 per day for their services.


You may need to hire a roofer to help construct your conservatory roof, who on average charge around £15 to £25 per hour or £150 to £200 per day. A window fitter may also be required to install double-glazing, which should cost around £10 to £20 per hour.


For your conservatory interior, you might want to consider hiring a painter and decorator who charges an average rate of £100 to £300 per day. You may also need to hire other tradespeople, such as an electrician, who normally charge around £30 to £60 per hour to fix any electrical systems or light fixtures.

How Long Does It Take to Build a Conservatory?

Another important aspect of your conservatory construction is the time it will take to build it, as this will help determine the final cost and how long it will take overall.


The below table sets out the time frame for the different types of conservatory.

Type of conservatory
Duration
Victorian 3 - 4 weeks
Edwardian 2 – 3 weeks
Lean-to 2 – 3 weeks

How Much Does Each Stage of a Conservatory Build Cost?

There are various stages involved in building a conservatory. To help you understand the costs of each stage, take a look at the following breakdown.

Building a Conservatory Base

Before building your conservatory, you need to make sure that you have a robust base to support it. This involves excavating the floor area where your conservatory will be situated. It will then be levelled, and the conservatory base should be formed using concrete which should cost around £90 per square metre.

Building Conservatory Wall

Once the conservatory base is built, a low dwarf-wall will need to be constructed to provide extra support to your conservatory. This will involve building the wall from the base upwards, ensuring that is it no less than a metre. The average cost of a conservatory dwarf wall is normally around £50 to £300 per m².

Building the Conservatory Roof

Once the foundations are in place, the roof can then be constructed. This involves installing the roof ridge and roof rafters, along with fitting the glazing sheets.


The price to install a conservatory roof will depend on the type you choose, as polycarbonate roofs tend to range from £2200 to £7300. While a glass roof usually costs around £2400 to £8000 to install.

Conservatory Fixtures and Fittings

The final stage of building a new conservatory involves fitting windows which cost around £150 to £200 per day for a full set of windows, while door installation costs around £390 to £900.


To furnish the interior, you will need to install light fixtures, which will cost around £60 to £100 per light. You will also need to pay to have your conservatory decorated which can cost around £300 to £500 to paint the walls.

Conservatory Roof Replacement & Repair Costs

After a while, your conservatory roof may need to be repaired for a number of reasons, including:

Roof leak repair

If you have a tiled roof, you may be able to pay to replace roof tiles to prevent your roof from leaking. The cost to replace roof tiles is around £120 to £200, although this will depend on the size of the roof.

Misted glass repair

If you notice that your glass has started to mist up, this means that your double-glazing may have failed. To repair your misted glass roof, this will involve removing the roof frame and replacing it with new double-glazing. This will cost around £50 to £450 per glass pane.

Roof replacement

In some cases, you may need to have your roof completely replaced. The cost to replace your conservatory roof will depend on the type of roof you choose.

Polycarbonate roof

The cost of a polycarbonate roof ranges from £2200 to £2700 for a lean-to conservatory, while an Edwardian conservatory can cost around £3400 to £6700.

Glass roof

Glass conservatory roofs are slightly more expensive, as they cost around £2400 to £3200, while an Edwardian conservatory ranges from £3700 to £7300.

Cost of Cleaning a Conservatory

To ensure your conservatory is long-lasting, you should try to perform a deep clean at least once or twice a month. This is especially important for your windows as they can be smudged easily and tend to generate a build-up of dirt.


You can clean it yourself using water and detergent, although it is a time-consuming job, so you may want to consider hiring a professional which will cost around £300 to £650 to clean the inside and outside of your conservatory.

Cost of Removing a Conservatory

If you find that your conservatory is letting too much cold in the winter, especially if you have had the conservatory for a long time, then you may want to consider removing it.


You may want to hire a professional to knock down or remove your conservatory which normally costs around £300 to remove the roof and windows. The cost to remove the dwarf wall will cost around £20 per metre, and the conservatory base should cost around £120 per metre to remove.


You will also need to pay to have your waste removed which normally costs around £70 to £300 for professional removal.

FAQs
