So, How Much Does a Conservatory Cost?

How much is a conservatory is a pretty vague question, the conservatory price you will receive can vary widely depending on:

 

  • The size
  • Colour
  • Design
  • Internal and exterior decor
  • Number of doors and windows
  • Power options
  • Overall dimensions

 

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.

Rough Conservatory Costs

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.

Fully fitted conservatory prices are really what you want to be shooting for as builders and companies are notorious for mentioning hidden costs further down the line.In this prices guide, we’ll look at the different types of conservatories, which makes up the cost and the average cost of each style.

Conservatory Costs - What Makes Up The Price

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.

Types of Conservatories and Associated Costs

In this section, we’ll take a more detailed look at how much conservatories cost by design and style. We will try to explain the differences in each conservatory style and why there is a difference in price.

Lean-To Conservatories

Lean-to conservatories are the most common style in the UK. Featuring a basic, three-sided design and usually with a polycarbonate roof, they generally take less time to construct than other forms. These are also what you would expect to see if you want a budget uPVC conservatory or if you are searching for cheap conservatory prices. Its simple design makes the lean-to easy to integrate with the existing decor of any home. However, please bear in mind the biggest complaint with this style is; due to the type of roof they get boiling in summer.

Edwardian Conservatories

The Edwardian conservatory is the second most common type from the wide range open in the UK and features a rectangular design which provides more floor space than its lean-to counterpart. They are usually built with a small brick wall or dwarf wall as its often referred too and installed with a polycarbonate roof as standard. I would speak to your conservatory installer and see how much more a tiled roof would affect the final price. An optional glass roof makes the Edwardian a great choice when adding a sunroom to any home.

Georgian Conservatories

The Georgian conservatory is sometimes referred to as a reverse-drop or hipped-back Edwardian. Many people confuse Georgian conservatories with Edwardian, but there are a few key differences between the two. One crucial distinction between them is that a Georgian generally has a larger footprint. This means you may need to obtain permission to have one of these designs constructed. That being said, the Georgian is one of the most straightforward designs and suits the majority of homes, especially if combined with existing Georgian architecture.

Victorian Conservatories

One of the period types of conservatory that can be found in rural or urban homes. These particular models are sometimes referred to as sunrooms as they provide a rounded appearance with high roofs. A simplified example of a victorian conservatory would consist of a bay fronted shape with anywhere between 3-5 sides and a slightly angled roof with a ridgeline. The most common type of roofing for this model are polycarbonate sheets due to them being lightweight and excellent value for money.

P-Shaped Conservatories

A P-shaped conservatory combines the styles of a lean-to conservatory and a Victorian. It features an elongated room with a short, round addition, hence the name “P-shaped.” This type takes up a good deal of ground area, so it is generally only suited to larger detached properties. Because they feature dual entry points from the home, P-shaped designs are an excellent idea for anyone looking to add a multi-functional conservatory extension to their property (such as a seating area on one side and a children’s play area on the other). Conservatory prices for P-shaped or Victorian usually start around £14,000 for a full build.

T Shaped Conservatories

Like P-shaped, T-shaped conservatories are great for those who want to add multi-functional living space to their property. The main difference between the two styles is shape and size; as its name suggests, the T-shaped resembles the letter “T” and are designed to run alongside a long wall. T-shaped prices vary depending on the choice of frontage (Gable end, Victorian end, etc.), but you can expect T shaped conservatory costs to start at around £14,000.

Gable Conservatories

The Gable is characterised by its vaulted glass-panelled roof, which allows for maximum sunlight and enhances the design’s bright, airy feel. These conservatories make great sunrooms, playrooms and pool enclosures. They are among the more substantial styles that are available, typically measuring 3.5 x 4 metres. The Gable method is designed to suit larger properties, and this is reflected in its higher price tag; purchase and construction costs can range from £11,000 to £15,000 depending on the roofing material and structural variation.

Conservatory Sizes - How Big Should a Conservatory Be?

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.

Groundworks and Foundation - The Base Work

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.

Access

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.

Conservatory Roof Costs

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.

Polycarbonate conservatory roof

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.

Solar Conservatory Roof

New to the conservatory roofing market, these roofs block the sun’s glare and help with furniture fading.

Dwarf Wall (half brick) or Fully Glazed Conservatories

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.

Heating the place

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.

Double Glazed or Triple Glazed

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.

Wooden VS UPVC Conservatories

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.

Guarantees and Warranties

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.

It's not just the conservatory design and size that impacts the price.

Building Work Requirements

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.

Planning Permission Requirements

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.

How far can you push it?

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.

Building Regulations

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.

What is a Conservatory?

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.

How is it different from an Orangery?

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.
