Conservatories let you enjoy your garden all year-round while bringing in all of that light from outside. Adding one to your property is a great way to add space and comfort. In this guide, we’ll look at how much it typically costs so you can get ready for planning out. Conservatory costs vary depending on size but our guide will help you plan for what suits your budget best.

What is the Average Cost of a Conservatory?

Conservatories are very popular in the UK, with three main types to choose from – Victorian conservatories, Lean-to conservatories, and Edwardian conservatories. 


Lean-to conservatories cost anything between £10,000 and $15,000 depending on where they’re made of and what style you want them to be. On the other hand, Victorian ones can be around £12,000 and go up as high as £20,000. Lastly, Edwardian conservatories will probably run closer to £13,000 and up to £23.000.


Conservatories come in a range of styles, with the most popular ones being Victorian conservatories and lean-to uPVC. Generally speaking, if you’re looking to add a wood conservatory to your property, it is going to cost you more.


Factors That Affect the Cost of an Added Conservatory

As mentioned previously, there are several factors included in the overall costs of a conservatory, regardless of the type.

These are the factors that will affect the price the most:


  • The type of glazing
  • The type of roof you choose
  • Additional features (extra heating, for instance)
  • Type and quality of the materials used in building it
  • Style (modern or traditional – Lean-to, Edwardian, or Victorian)
  • The size (small, medium, or large – the bigger, the more expensive) 


In order for your conservatory not to cost as much money, first think of how big it needs to be and what style/kind of roof would go with its size best. 


After that, decide on which materials should make up your structure so they do not affect the price too badly either way (e.g., wood or PVC). 


Finally, take into account any ground preparation work if needed along with additional features such as underfloor heating.


Types of conservatory

Conservatories come in different sizes and shapes and it can be difficult to choose what model to go for. From regular glass rooms to remarkable glazed extensions and more, the choice can be complex if you are new to this. Here below you will find the most common types of conservatory.

Lean-to Conservatories

A lean-to conservatory is a three-sided structure attached to one side of the property. They generally have sloping roofs and tend to be the easiest and cheapest type of conservatory. All costs considered the average price range between £9,500 – £13,500.


Victorian Conservatories

A Victorian conservatory is a versatile type of conservatory that you can find in properties in the UK. The typical Victorian conservatory has a rounder frontage as well as a pitched roof. The average price for this kind of structure falls between £12,000 to £17,500 depending on the size, style, features, and more.


Edwardian Conservatories

Edwardian conservatories are very similar to Victorian ones. The main difference is that they have a flat frontage rather than a curved one. While they’re similar, the price slightly varies between both for material and built process. On average, the cost for an Edwardian conservatory is anywhere between £9,500 to £15,000.


Orangery costs

For a long time, conservatories have been more popular than orangeries due to their lower cost and less bulky design. However, they now come at a higher price tag and, if budget allows, it might be worth considering an orangery instead of just sticking with the traditional options. The cost can vary depending on the size but you should expect an average cost between £30-35k for a 16m2 orangery.


What Are the Main Costs of a Conservatory?

As discussed above, there are several elements to take into consideration when planning out your budget for a conservatory. The 5 most important factors to consider in terms of conservatory prices are: 


  • Conservatory size

Of course, the bigger the conservatory, the costlier it gets. For instance, the average price for a lean-to conservatory is £11,000. But it will be much more expensive to build a 30m2 than a 15m2, obviously, in terms of material, planning, and finishing.


  • Finishing

Often easily overlooked, the finishing needs to be taken into consideration as it affects your overall budget. For instance, the flooring, the furniture, the roof design, and more can highly impact the costs.


  • Type of roof

Another element to affect the conservatory cost in 2021 is the type of roof. For instance, a glass roof will let lots of sunshine in during sunny days and will cost more. Also, glass or even a tiled roof will generally speaking, cost more than a roof made of polycarbonate. Another important thing to keep in mind is that conservatory roofs can be expensive to maintain, with many people having problems such as leaks and discolouring over time.


  • Materials used

The main materials used in the construction or extension of contemporary conservatories are hardwood, UPVC, or aluminium. Needless to say, wood or aluminium will be in the higher price range than polycarbonate panels and tiled roofs.


  • Design chosen

Design is the biggest factor when considering the conservatory price, but size also plays a major role. Would you prefer investing in a bigger and more premium space for the future or a more basic design simply to add value to the property?


All in all, these are the main costs to consider when planning a conservatory in 2021 and you should include them all in your budget.


How Long Will It Take to Build a Conservatory in Your Property?

The time it will take to build your new room is one of the most important things you should consider when determining the final conservatory costs.


First of all, for Edwardian, Lean-to, and Sunroom conservatories, the average duration will be 2 to 3 weeks. Secondly, for Victorian conservatories, the estimated building duration is 3 to 4 weeks. Lastly, the average timing to build an orangery conservatory is from 4 to 5 weeks.


Of course, there are general timeframes that are usually estimated. However, there might be changes in the constructions which can cause it to last longer than initially planned.
