Conservatory Prices 2021
How much are Conservatory Prices in 2021?
A natural question for those homeowners who are looking for a value for money way to extend their family home with a new or replacement conservatory is “How much will a conservatory cost in 2021?”
It’s more than understandable to want to get the best deal when we buy something, and it’s especially true when you are looking to invest in a “big-ticket” item like a new conservatory for your home. So let’s take a look at what you can expect with our useful guide to conservatory prices.
Design & fittings influence conservatory prices

You could probably find prices for a cheap lean-to conservatory from around £5,000 if you are looking at a smaller room. Having said that, if you want a full glass roof or dwarf walls, or something in the region of a 3×3 conservatory, then the cost is going to rise.
As a rough guide, in terms of general prices for conservatories, going from the cheapest conservatory style (1), to the more expensive (6), you should find the cost goes up in line with the complexity of the design. Lean to being quite simple and orangeries being more detailed.
How much does a cheap conservatory cost?
- Lean to: From around £5,800
- Victorian: From around £6,500
- Edwardian / Georgian / Elizabethan / Regency: From around £8,500- £10,000
- Loggia / T-shape / P-shape / B-shape etc: From around £15,000
- Small orangery conservatories: From around £18,000
- Orangery conservatories: From around £20,000
So, as you can see, the type of conservatory that you want to build will have a significant impact on prices.

Cheap Conservatories – how to buy a conservatory on a smaller budget?

To get a really cheap conservatory deal, you will have to be prudent and choose your options to match your budget. But there are a number of things you can do to end up with a low cost conservatory. Even though you may be on a tight budget you can still get a high quality, low price, conservatory.
- Use polycarbonate for the conservatory roofing – the lowest cost option.
- Have less opening sections in the side frames – each opener can be charged as an optional extra
- Use a full length glass design – having dwarf walls will increase the conservatory cost.
- If possible, have a pre-fabricated steel base – it’s cheaper than digging foundations.
- Use white UPVC – generally cheaper than timber or aluminium. Coloured UPVC is costlier.
- Use “standard issue” window & door furniture.
- Keep your conservatory size below that which may need planning permission.
- If possible, or necessary, prepare the ground yourself, the contractor could charge for doing it.
- Use standard double glazed units. 28mm units, argon filled or fitting low-e glass can add costs.
- Get as many written estimates as you can, and always try to negotiate a better deal.
- Try to avoid the “peak season” for contractors (spring / summer).
- Is there potential to by an “ex-display” model? – some installers have showrooms that they will sell stock from.
If you stick to the basics, it is still possible to find a fully fitted cheap 3×3 conservatory for under £6,000.
N.B. don’t forget to confirm that the quotes you are given by a supplier cover conservatory prices including installation, warranties and any VAT – check for any “hidden-extra’s”.
What are the main conservatory costs?

There are 5 basic factors to consider when it comes to 2021 conservatory prices, and those are:
Design: As mentioned previously, the final design choice is going to be a major pricing factor – are you going simple or grand?
Size: Obviously, the bigger the conservatory you want to build the costlier it is going to be. If you are thinking of a P-shape or similar “bespoke” design, then almost by default, it’s going to be quite large.
Materials: The 3 main materials used for contemporary conservatory designs are Timber (hardwood or engineered wood), Aluminium or UPVC. It’s probably safe to say that, of these materials, hardwood or aluminium will be in the higher price bracket.
Roof: Your choices are to have a fully double glazed conservatory roof, one made from polycarbonate panels or a tiled conservatory roof. Having a fully tiled conservatory roof is the costlier option.
Finishing: Sometimes easily overlooked at outset, the finishing of your new conservatory is something that needs to be taken into account for your budget. What flooring, lighting, power outlets, heating, décor or furnishing are you going to want?
One element of expense that may or may not need to be taken into consideration is planning permission for a conservatory. Usually, for an average sized or small conservatory, planning permission is not automatically required, but you do have to follow the rules.

Conservatory extensions: How much do they cost?

The basic idea of any conservatory is to extend the living space of your home. In that way, some conservatories are built to meet a specific purpose, such as a kitchen conservatory.
Kitchen conservatories are very popular. Because they not only allow for the increased work and family space, they also bring a huge amount of natural daylight into the room. Making your kitchen not only a super place to cook, but also a really great social hub for your family to enjoy.
Of course, you are likely to have to pay a bit more than usual, even for a small kitchen conservatory extension due to the cost of buying & fitting the new kitchen itself.

As a popular size for most double glazed conservatory installations you can find a wide range of prices in the market. The sizes are approximately 3,000mm square or 4,000mm square. The sizes are approximately 3,000mm square (or 9m2). You may also want to consider a 4×3 conservatory design.

Conservatories for Bungalows
It is often said that a lean-to conservatory is best for a bungalow because both the bungalow and the lean-to have low rooflines. This, however, is not necessarily always true. By taking some time to consider varying design options, you may very well find that you are not limited to using just a lean-to extension.
Many bungalow conservatory extensions are of the lean-to style, and they are built so that the top of the conservatory roof slope is no higher than the rainwater gutters on the main house. However, by extending the height of the conservatory, and with some design flair, you could take advantage of designs such as the Gable, Edwardian or even Georgian conservatory type.
How much do conservatories for bungalows cost? Once again, it will depend upon the final design, but budget conservatory prices for a bungalow can start from under £6,000.

Small Orangery Conservatories and Glass Conservatories


As two of the more bespoke styles of room, both Small Orangery Conservatories and Glass Conservatories are not what you would call “budget conservatories”.
Orangeries have long been a favourite of homeowners with a good budget wanting a more “substantial” room without the need to build a bricks & mortar extension.
There are quite a large number of options when it comes to orangeries as the styling encompasses both the modern and traditional approach.
2021 orangery prices have remained stable, so you can still find orangery costs of between £15,000 & £20,000.
Glass conservatories, or glass rooms, are a more recent trend in conservatory design and make use of structural “engineering grade” laminated glazing to form the sides and roof.
How much do glass conservatories cost? Well that, once again will depend on what you are building, but if you are not having an architect designed, bespoke, glass conservatory you may find prices at:
- Lean-to Glass conservatory 3.0m x 3.0m could cost in the region of £7,500 to £10,000
- Victorian Glass conservatory 3.5m x 3.5m could cost in the region of £10,500 to £15,500
- Loggia Glass conservatory 3.5m x 3.5m could cost in the region of £10,000 to £15,000
For the top-end designer glass boxes, you are going to need a bigger budget, as even a medium sized 4×4 glass box conservatory can be priced from over £35,000.

Conservatory prices 2021 – summary

Even though the examples of conservatory cost in this article are given as a rough guide, it can easily be seen, that for those homeowners who are in the market for a cheap conservatory, then the best option would be to look at the lean-to design. Especially UPVC lean-to conservatories.
In terms of value for money, UPVC conservatories also stand up well against the competition. Oak Conservatories, or other hardwood conservatory designs, as well as aluminium conservatories have some wonderful examples in the market. But you will find that the prices are higher than those for an equivalent sized UPVC conservatory extension.
Alternatively, Loggia conservatory rooms and glass conservatories are a couple of styles becoming more popular with homeowners who are looking for “something different”.
Whatever your style, or whatever your budget, we can help you get the most competitive conservatory prices from accredited installers no matter where you live in the mainland UK.
