What Else Can Affect The Price of Your Conservatory?

There are many other factors that contribute towards the difference in conservatory costs other than the design of the conservatory such as:

  • Size: Projection & Width

  • Building Requirements
  • Electrics & Lighting
  • Climate Control

It is important to remember that it is not just the style of the conservatory to fit your home that matters but also which type of conservatory offers you the most advantages to your lifestyle regarding how you use the space and spend your spare time.

Your lifestyle will affect how expensive your conservatory will be. If you want a small space to relax, then this could be cheap and affordable. But if you want a larger conservatory for those weekend gatherings, you are looking at a more expensive room size. This is because if you are looking at a more expensive budget, this can result in more space to expand.

Roof Design and Material

Another factor that will play into the budget for your conservatory is what type of roof you will go for. There are varying costs that come into play. For example, a glass roof is a sturdy material and comes with advanced double glazing, letting plenty of natural light into your home.  so it’ll be on the more expensive side, whereas a polycarbonate roof is perfect if you’re on a budget because it is very easy to fit. That way, you can enjoy it for longer.

A solid roof provides many benefits for your home. It’s thermally efficient, and it will let natural light in your home. It creates a classic roof with a modern feel. It can also expand your living space. In comparison, a tiled roof is also a cheap way to rebuild because you don’t have to worry about affecting your existing style.

Colour and Finish

There are many different styles, colours and finishes that will help spruce up your conservatory. But how much or little personality will add to its overall cost. If you go for a more daring colour and more customisation options, you will expect to pay more money. If you don’t want to add a lot to your conservatory, then it will be a cheaper installment.

Number of Windows and Doors

Another factor to consider is the number of windows and doors for your conservatory or extension. You can have as many windows as you desire, which will increase natural light in the process, and make your conservatory warmer and more comfortable. If you only want one door, this is perfect for if you’re on a budget, however, you also have the option of multiple doors too if you want to increase your living space. Multiple doors will also increase access to your garden and make it ideal for warm summer days, however it can increase the initial cost of your conservatory.

Material of the Windows and Doors

We offer both uPVC and aluminium finishes, which can vary in price. A uPVC conservatory is a robust and sturdy build while also being very cheap to install. In comparison, aluminium is a much stronger metal that keeps your home warmer and protected in the long run. If you have more money to play with, an aluminium conservatory will be a more suitable option. The material you choose will largely affect the thermal performance and the cost of your conservatory.

Conservatory Prices by Style

Each conservatory style is unique and provides different benefits. This is why conservatory prices can vary drastically based on the style of conservatory you choose. You can view our prices table for each conservatory style and compare.

Lean to Conservatory

The cost of a lean to conservatory varies greatly. It depends on the size of the build, so there is that to consider. If you have a small property that ranges from 3500 x 2500, then a polycarbonate roof is cheap and affordable, while a glass roof is more sturdy and thermally efficient. This means it will cost much more, especially if your home requires a larger space.

Edwardian Conservatory

An Edwardian Conservatory is an equally classic design with slim sightlines and makes the floor space bigger. This is perfect for gatherings and can enhance the size of any home.   Because of their design bringing in natural light, and increasing the space, they are much more expensive than a lean-to conservatory.


Conservatory Size (mm) Roof Material Guide Price
3500 x 3500 Polycarbonate £9,000 – £10,500

Gable Conservatory

A glass roof in comparison is around £12,500. This is because they are more sturdy, quieter and thermally efficient. If you want to add extra brickwork, this will also increase the cost, but it will add more privacy to your home and blend in with the property.

If you want a polycarbonate roof, then the prices will range between £12,500 – £15,750, while a glass roof will cost anything from £13,000 – £16,500. Of course, this depends on the size of the room, so you have to take that into consideration. Additionally, if you want to add some bespoke elements, this will cost you more as well.

T-Shaped Conservatory

If you would like a fully built conservatory with a dwarf wall, then the prices will be on the high end budget. If you have a room that is a size of 5000mm x 3500mm, there is only a small price difference because of the roof. If you want a polycarbonate roof, you will pay anything between £13,000 -15,000 but if you opt for a glass roof, then you will pay between £14,000 – £15,500. This shows a big price difference, so the choice is up to you, depending on what your budget is.

L-Shaped Conservatory

In comparison to Victorian and Gable End Conservatory, an L Shaped Conservatory is a cheaper and cost effective option. This is because it slots seamlessly into your house, like a lean to conservatory. You will experience cheaper prices for your conservatory because it will give you more space. But if you want to customise your conservatory from start to finish, your space will be more expensive.


Orangery and Extension Prices

Orangeries and Extensions both have different benefits to a standard conservatory but they can be more costly. Orangeries are considered a more bespoke variation of a conservatory. They typically feature fewer windows than a typical conservatory so less natural light should be expected from an orangery. Extensions can feature a sturdier roof and also fewer windows but they would generally require building permission and will also be more expensive than the price of an average conservatory because of this.

You can view our guide prices in the tables below to see the price you can expect to pay for an orangery or extension. Please note that orangeries and extensions prices can vary drastically depending on the size and materials you choose.


The cost to install an orangery all depends on the size of your build. If you have a smaller house, it will be cheaper and more affordable, however, for a bigger home, it is going to be more expensive. You can pay anywhere between £10,000 – £60,000 depending on how big your house is. If you want to install a high end orangery, you could be paying between £45,000 –£60,000.


If you are looking for an extension, there are plenty of customisable options to consider. You can add more space by including more windows and doors, but this will also cost you a lot of money. But on the other hand, if you want to go for a bespoke extension where you can create your build from the ground up, it will cost you much more.
