Orangery Cost Guide – How Much Does It Really Cost?

You might be thinking of adding an orangery or conservatory to your home. Orangeries have become more popular as an alternative to traditional conservatories. 

But how much does orangery cost in 2025? In this guide we will look at the factors that affect the overall orangery cost and explain why conservatory roof insulation is a smart investment. 

What is an Orangery? 

An orangery is a home extension that is between a traditional conservatory and a brick-built extension. It was originally made to grow citrus trees in the 17th century. Modern orangeries are functional rooms with large windows and a partially solid roof which is often lantern. 

Key Differences Between an Orangery and a Conservatory 

Average Orangery Cost in 2025

The cost to build your orangery depends on different factors such as the size, materials, roof type and glazing option. Here is a brief look:

Key Factors that Affect the Cost of an Orangery 

There are different factors that will affect the overall orangery cost. This includes: 

1. Size and Layout – 

Larger orangeries will need to have more materials, labour and time to build. If you have the orangery designed to be more complicated such as curved walls or multiple entryways this may also raise the cost. Also, the intended us of your orangery may have an effect on the price, whether you’re choosing to use your orangery as a kitchen extension, lounge or dining room. 

2. Materials – 

When choosing the design of your orangery, the quality of materials used will affect the cost and lifespan. 

3. Bricks – 

If you choose to use premium bricks this will naturally cost more than standard bricks. 

4. Glazing – 

The type of glazing you choose will affect the price and energy efficiency. Double glazing is the standard choice, but you could purchase triple glazing which provides superior thermal insulation and external noise reduction. The size of the windows you choose will also change the price. 

5. Roofing – 

The roof structure and type of conservatory roof insulation is a key factor in cost. Basic polycarbonate or glass roofs will be cheaper but offer poor insulation. We recommend choosing an insulated conservatory roof which drastically improves energy efficiency, saving you money on your energy bills.

Conservatory Roof Insulation for Orangeries

We recommend conservatory roof insulation, as it offers plenty of long-term benefits ensuring comfort, energy efficiency and increased property value. Orangeries are known for their solid brick walls combined with large, glazed areas and a lantern style roof. However, if they are not properly insulated, they can suffer the same as traditional conservatories, by being too hot in the summer and too cold in the winter. Having conservatory roof insulation properly installed will resolve these issues.

Benefits of Conservatory Roof Insulation 

The benefits of conservatory roof insulation include:

1. Reduces energy bills –

If your conservatory or orangery is badly insulated or uninsulated, it can let too much heat in the summer and let heat escape in the winter. This can make you rely on central heating or air conditioning. By having conservatory roof insulation installed it will maintain and control the temperature in your conservatory or orangery all year round. This will lower your energy bills, saving you money. 

2. Improves temperature control –

If you have a conservatory or orangery with a basic roof polycarbonate or glass, you might have noticed that the temperature is inconsistent. You can resolve this issue by having conservatory roof insulation installed. The insulation creates a barrier that slows down heat transfer. By having the temperature maintained and controlled you will be able to use your conservatory or orangey all year round. 

3. Reduces noises from external sources –

Having your conservatory or orangery properly insulated will help to reduce the noise level from outside. This is good if you live near a busy road, school or urban area. The roof insulation absorbs sound, reducing the level of noise that enters your orangery or conservatory. It results in a quieter room for you to enjoy all year round. 

4. Increase the value of your home –

If you invest in roof insulation for your orangery or conservatory you will add long term value to your home. By having conservatory roof insulation installed your home becomes more attractive to potential buyers, as the room becomes energy efficient and usable all year round.
