There are full-range conservatory styles available, and the average cost of a conservatory can vary depending on where you live in the country, the type of conservatory you choose and who you contract to do the installation.
Additionally, it would help if you decided on different factors like whether you want a hardwood install or a UPVC conservatory. If the research has already started and you know the exact style of conservatory you’d like, then you can get the best free no-obligation prices from approved local installers below.
How much is a conservatory is a pretty vague question, the conservatory price you will receive can vary widely depending on:
These are most important considerations to consider when estimating the total cost of a conservatory, however, are building work requirements, planning permission requirements, and whether it will be subject to any building regulations will also play a part.
A written quote for the supply and full installation, including any extras mentioned, is what you want before you agree to anything. With conservatories prices, including installation are usually standard but do your checks.
Though, you can expect to pay anywhere from £5,000 for a basic lean-to conservatory. And up to £15,000 for a deluxe Gable with a glass-panelled roof. Remember size will affect the cost massively, so think long and hard about what you need versus what you would like. Below, we’ll take a closer look at the design features and typical conservatory construction costs.

The prices of conservatories per m2 vary widely up and down the UK and this due to several certain factors, not least the materials used and the labour involved. Some new conservatory builds will require far more tradespeople and expertise than others.
Because there is no average conservatory cost that you can rely on, In this section, we break down all the aspects that could go into a new conservatory installation and what impact they could have on the final price.
The conservatory size that you choose will have the most significant impact on price bar none. Conservatory prices are worked out on the basis of a square metre which you will often see quotes that reference the m2 metrics.
The smallest is usually 3m x 3m conservatories, and these are particularly small if the purse-strings allows I would recommend going more extensive than this shoebox size. In terms of a maximum, you can cover up to 30sq/metres of floor area before permission needs to be granted.
If you need further info on the regulations and how big can a conservatory can be then check out what the planning portal says.
The conservatory floor will need to be built on a safe and solid foundation that is free from damp issues and suitable for a conservatory structure.
This means that a wet garden area that retains water and doesn’t drain well will need to be removed.
The same with a solid concrete pad that collects water. An area like this would not be ideal for building a conservatory. What you currently have to work with, will go a long way to deciding how much initial groundworks are required for your new conservatory. Also, if you have chosen a dwarf wall, then brickwork foundations will need to be installed, which will increase the conservatory price again.
When obtaining a conservatory price, one of the very first aspects of the project conservatory installers will look at is the access. Now, most properties have a side gate and simple access to the rear of the property, and if this is you, then you don’t need to worry about access.
But if you have terrible access, or worse you can only access the back garden from through the house or over a garage then this is terrible news, and lots of conservatory installers will walk away, or increase the price significantly. Inadequate access means more time and a lot more hard work, and for companies that install conservatories, time is money.
Before conservatory companies even arrive, try to work out how the access will be, how you can improve the situation before they start the quotation process.
There are more options now with conservatory roofs than there has ever been and this is one part of your new conservatory you will want to think about
Tiled conservatory roof. A tiled conservatory roof is a lot better than a polycarbonate roof as well as being a lot more expensive.
In the last 5 years, there has been a massive surge in customers looking at conservatory roof replacement. By this, they are looking to remove the original polycarbonate roof and replace it with a tiled roof. Read more here about it. A tiled conservatory will be more energy-efficient and more cost-effective. If budgets allow going for a tiled conservatory roof is the top choice.
A polycarbonate conservatory roof is the first option that most conservatories came with, they are cheaper than most other roof choices, and for a lot of people work perfectly fine. The chief complaints with these roofs, is they lose heat in the winter and are too hot in the summer.
New to the conservatory roofing market, these roofs block the sun’s glare and help with furniture fading.
Simple enough! You will need to choose between whether you would like the first half of your conservatory sides to be brick or a dwarf wall as they say in the trade, or whether you want the whole conservatory to be uPVC and fully glazed.
When heating conservatories, you’ll also need to comply with regulations if it is independently heated.
Before consulting with a company or builder, it’s a good idea to check with your local planning authority as to whether the structure will need to meet specific standards. For additional heating solutions in the winter, for instance just use a heater.
Most new conservatories are double glazed as standard, years ago many wooden conservatories would be single glazed, and this would be a nightmare for heat control. Double glazing put a stop to this and was a lot more energy-efficient. Times have changed again, and triple glazing has entered the market. The benefit of triple glazing is as follows:
While many people will still opt for double glazing in their new living space, for the extra cost a triple glazed conservatory is worth asking about.
Hardwood conservatories look fantastic and certainly have a place in the market. On older homes like farmhouses, a uPVC lean-to conservatory may well look out of place, if the original dwelling is all wood and double glazing then uPVC will stand out for the wrong reasons.
Secondly, maintenance is an issue, like anything on your property that is built with wood, regular maintenance like painting will be essential. Surprisingly UPVC is cheaper than wood, less maintenance and in most cases more modern.
Reputable conservatory companies will always provide comprehensive warranties with the price of a conservatory. Fly by night cowboys who don’t expect to be in business in say 5 years, don’t think about this. Therefore they don’t include these possible hidden costs in their conservatory prices and quotes.
Always make sure that the conservatory price you get includes an extensive warranty, and if possible, you want independent insurance backed guarantees.
Building work on conservatories, if it is required, affects the price considerably. Section 3 of the Building Act defines building work as” work for or in connection with the construction, demolition or removal of a building.” If you’re rebuilding, replacing or upgrading an existing build you may need a building permit. Again this will increase the price.
Whether or not your conservatory building will require planning permission from your local authority will depend on the size of the structure on a square metre basis.
It shouldn’t need planning permission if it doesn’t stretch farther than 0.9 metres past the wall of your property and doesn’t rise above the tallest point of the property’s roof.
More on dwarf wall planning consent here.
Those with semi-detached or detached homes have a little more wiggle room with conservatories; it can stretch to a maximum of 70 cubic metres from the property or 15% of the property’s volume up to 115 cubic metres (whichever measurement is larger).
Planning involves an extra cost, so speak with a contractor about whether permission will be required or not.
The UK Government has implemented building regulations to ensure that all new buildings meet minimum safety and security standards. In most cases, conservatories do not need to comply with building regulations, but there are a few circumstances in which the rules must be met.
If your conservatory will be built above ground level, for instance, or stands entirely separately from the property, government building regulations will apply. It’s challenging to get an exact conservatory cost calculator.
The word conservatory or conservatories is a broad term encompassing any structure that has a glass roof and walls ( a dwarf wall in a lot of cases) and is attached to a property at least on the side. They are commonly used as sunrooms, enclosed porches and pool enclosures.
What’s the makeup?
While there is no official legal definition specifying what makes a structure a conservatory, this type of structure typically comprises a minimum 50% sidewalls or dwarf walls and glass or uPVC roofing that is at least 75% transparent.
Conservatories are often referred to as extensions, but it’s important to note that they aren’t indeed extensions in the legal sense of the word. The main distinction between the two types of structures is that extensions require permission from a local authority, where conservatories generally do not. Also, prices for later will be way lower.
The terms “conservatory” and “orangery” are often used interchangeably, but the two structures are not the same. An orangery is a more substantial, more high-end addition to a property, but building one typically requires approval from a local authority where lots of conservatories are built without.
An example of an orangery is the lantern roof conservatory. As their name suggests, these orangeries feature cantilevered lantern-style roofs. The glass-panelled roof style allows for an abundance of natural light while also ensuring the utmost in privacy.
As with conservatories or orangeries, they vary in price depending on the design, construction materials, and interior and exterior finishes.
An orangery is way more expensive than a conservatory
Orangery prices are typically higher, however, with prices ranging from
£10,000 to over £20,000.
I think with all the information covered above we have established that there is no average conservatory cost, the prices will vary based on what you the customer would like and what the budgets will allow.
It’s entirely possible to have a small new conservatory built for under £5000 as it’s also possible to have a conservatory not much bigger that cost over £20,000.
When building a conservatory without planning permission, there are a few key points to consider first. According to the Planning Portal, you can create a single story extension without conservatory planning permission if it is a maximum of 4m high or 3m high (within 2m of a boundary).
Also, other vital facts include that it is no larger than half the garden, the top of the conservatory is no higher than the eaves of a properties roof, and side extensions can not be any wider than half the width of the house.
A conservatory roof cost varies depending on the size, quality and glass options. HouseHold Quotes forecast that a lean-to conservatories can cost between £2000-£3000 for a polycarbonate or glass option installation.
A victorian conservatory is slightly more expensive at around £3500-£6000 depending on the height and width. Whilst a Georgian conservatory can be anywhere between £3500-£7500.
Our friends over at Job Prices put together a great article explaining the various costs and put together a guide price. On average the exterior of a glass conservatory can cost about £125 to clean.
If you want both interior and exterior done you’re looking at about £300. For a full valet service of an average-sized conservatory, prices tend to start around £600.
According to Onthemarket, no doubt adding a conservatory increases your property value, by how much though, that is the all-important question.
On average, the value of your home will increase by 5%; if you have a more expensive conservatory or a house in London, for example, then this could go as high as 10%. In most cases, you will recoup the conservatory cost on the value of your home.
When making an enquiry, you must have a list of all the conservatory questions you want to ask and go to at least 3-4 different companies and ask for a quote.
This is simple enough for any home renovation, you should always seek a second opinion to make sure you’re not getting ripped off or that the standard of work is poor. Conservatory installations are not cheap at all, so you want to make sure you’re getting good value for your money.
Usually, one company can do the whole installation for you. Here are some top tips to remember before hiring, have they done similar jobs before, ask for some previous work examples.
Look for experience as much as accreditation, be aware that subcontracting can complicate the process. Get like for like quotes and establish a payment plan with them, so everyone understands how the process is going to work.
Yes, according to Money Saving Expert different companies will ask for various deposits.
Some local independent firms may ask for 10% of the conservatory cost upfront and the rest on completion whilst others may ask for up to 30% before starting.
It comes down to whatever you feel comfortable paying and how much you trust the company. Always do your research, so you are not handing money to a company that is in financial trouble.
Do your research online or ask trusted family or friends who have had work done in the past on their houses.
If you decide to go online, visit websites such as Trust a Trader and read the real reviews from previous customers. Always look at how many reviews they have had (the more the better) and compare what sort of score they are averaging out of 5.
Which gives us a great breakdown of the vast range of conservatory styles on today’s market. The most affordable and widely chosen is the lean-to conservatory model due to its affordability and value for money. However, for higher budgets, these are also very popular:
