Fully Fitted Conservatory Prices: (True Cost & How to Save)

We deep dive into the costs to build a conservatory and the prices you can expect to pay. Below we cover everything from materials, supply only and installation in our updated 2023 conservatory cost guide.

When it comes to fully fitted conservatory prices, what exactly should you expect to pay for your new living space. There are full-range conservatory styles available, and the average cost of a fully fitted conservatory can vary depending on:

  • Where you live in the country
  • The type of conservatory
  • Who you contract to do the installation.

How Much Does a Conservatory Cost?

Depending on the size and style, conservatory prices fitted can be anything from £4,000 to ten times that number. The average fully fitted conservatory cost is £6000 – £10,000 in the UK 

Do Conservatories Add Value?

According to Everest, a conservatory can increase the cost of your home by between 5 and 12%.

No doubt adding a conservatory increases your property value, by how much 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 installers cost on the value of your home.

Supply Only: A Typical Conservatory Prices List

Conservatory installation is a job best left to the professionals in most cases however you can save money by doing the work yourself if you’re a DIY expert or paying a local tradesperson to erect your conservatory extension.

Below find the different styles of conservatories and associated costs involved with each installation.

Lean-to

The average Lean-to conservatory cost  is £8000 – £9500

A lean to conservatroy is your basic conservatory and are the most common style in the UK. Featuring a three-sided design and usually with a polycarbonate glass roof, a lean to conservatory generally takes less time to construct than any other new conservatory. These are also what you would expect to see if you want a budget uPVC and glass conservatory or if you are searching for cheap conservatory prices.

Edwardian

The average Edwardian conservatory cost fitted is £5000 – £7000

The Edwardian conservatory is the second most common type from the wide range open in the UK and features a rectangular design which provides extra space than its lean-to counterpart. The Edwardian conservatory is usually built with a small brick wall and installed with a polycarbonate glass roof as standard. An Edwardian conservatory cost can vary but is one of, if not the cheapest in terms of price.

Georgian / Hipped back

The average Georgian conservatory cost fitted is £8000 – £11500.

The Georgian conservatory is sometimes referred to as a reverse-drop or hipped-back Edwardian. Many people confuse quality Georgian conservatories with Edwardian, but there are a few key differences, one being the conservatory costs. Another crucial distinction between them is that a Georgian generally has a larger footprint. This means you may need to obtain permission, which will add to the final cost or price.

Victorian

The average Victorian conservatory cost fitted is £8000 – £11500.

One of the period conservatory types can be found in rural or urban homes. A victorian conservatory can sometimes be referred to as sunrooms as they provide a rounded appearance with a high conservatory roof. The conservatory prices on a victorian conservatory vary depending on size and other factors.

Gable

The average cost of Gable conservatory fitted is £11500 – £13500.

The Gable is characterised by its vaulted glass-panelled conservatory roof. The standard conservatory glass panels allow for maximum natural light and enhance the design’s bright, airy feel. These quality conservatories make great sunrooms and pool enclosures and are sort of at the middle range for conservatroy prices.

P-shaped

The average cost of a P-shaped conservatory fitted is £12500 – £15000.

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. This type takes up a good deal of ground area, so it is generally only suited to larger detached houses.

T-shaped

The average cost of a T-Shaped conservatory fitted is £12500 – £15000.

Quality 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; they are designed to run alongside a long wall. T-shaped conservatory costs can be more than others.

Orangery prices

The average cost of orangeries is £20,000 to £50,000.

The terms “conservatory” and “orangery” are often used interchangeably, but the two structures are not the same. An orangery is a more substantial building, a more high-end quality addition to a property, with less double glazing. Still, building one typically requires approval from a local authority where lots of conservatories are built without. A lot of people upgrade from a conservatory to an orangery. These are nowhere near the same as conservatory costs and you can expect to pay far more.

It’s here for Orangery prices.

Small 3x3 conservatories Prices

This is the most common type of conservatory as being under 3 metres deep and less than 3 metres high, it doesn’t require planning permission. However, there is a misconception that all these conservatories are small, which may not be the case.

A 3m x 3m UPVC conservatory can run the whole width of your house and of course, the price will depend on the material, whether you have dwarf walls or full glass and whether you go for a polycarbonate or tiled roof.

A small 3×3 conservatory price can be as little as £2,000 for supply only, whilst an Edwardian conservatory may cost upwards of £8,000 with installation and orangeries even more.

Large conservatory

The cost of a conservatory will obviously increase in relation to size and you will also need to factor in planning permission costs if required.

Once again, the style you go with whether that’s a lean to conservatory or an edwardian for example will influence the conservatory costs, with a timber conservatory or orangery with tiled roofs topping the list.

Conservatory Price Factors

Below we will look at the prices of conservatories section by section and where your money will be spent.

Floor Plan - What is the average size of a conservatory?

The conservatory size that you choose will have the most significant impact on conservatory costs. Conservatory prices are worked out based on a square metre and you will often see quotes and costs that reference the m2 metrics.

The smallest is usually 3m x 3m conservatories, which are particularly small. If the purse strings allow, I recommend going more extensive than this shoebox size.

The most common size for a conservatory extension is approx 3 metres by 2.5 metres, or 10 x 8 feet; this is a small conservatory.

How big can a conservatory be without planning permission?

In terms of a maximum, a conservatory can be up to 30sq/metres of floor area before planning permission needs to be granted

However, there are some exceptions, such as if you reside in an area that falls within an Article 4 Direction, if the conservatory is on the side of the house, or you own a listed building.

Those with detached homes have a little more wiggle room with quality fully fitted 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 around your house and garden involves an extra cost, so speak with a contractor about whether permission will be required or not.

If you need further info or want building regulations approval and to find out how big can a conservatory be then check out what the planning portal says.

Basework - Do you need foundations for a conservatory?

The conservatory floor will need to be built on a safe and solid foundation 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. A site like this would not be ideal for building a conservatory. When replacing an existing conservatory, the brickwork material can remain a lot of the time.

Yes, like any extension, a conservatory does need foundations and walls to keep the structural integrity of the build. These should be at least 1000mm deep and could need to be even deeper if there are trees in the vicinity and depending on the type of soil.

One of the very first aspects of the project a potential installer will look at is access. If you have a side gate don’t need to worry.

But if you have terrible access before conservatory companies even arrive, try to work out how the access will be, and how you can improve the situation before they start the quotation process. The price will increase if access is a real issue.

Polycarbonate or Tiled Conservatory Roof

There are more options now with conservatory roofs than there have ever been and this is one part of your new conservatory you will want to think about a tiled conservatory roof. A solid roof is a lot better than a polycarbonate glass roof and conservatory roof replacement is now a huge industry in the UK and the costs are not cheap.

A polycarbonate roof is the first option that most conservatories come with; they are low cost and cheaper in price than tiled conservatory roof choices, and for a lot of people, work perfectly fine. 

The chief complaint with this conservatory roof over a solid roof is they lose heat in the winter and are too hot in the summer. If you can, go for a solid roof, even if the price is more as in the long run its worth it because of the material.

Can a conservatory have a solid roof?

Yes, a new conservatory can have a solid roof and in fact, choosing a tiled roof instead of a glass roof has many benefits, which you can find below:

Improved energy efficiency – Because of the extra superior insulation, it means you can use the conservatory all year round and your heating costs will not be as much as with a glazed roof.

Opt for a tiled conservatory roof, the epitome of energy-saving solutions for both new and existing conservatories. These roofs, boasting comprehensive insulation, can achieve remarkable U-values dipping to 0.15. This level of efficiency outperforms an A-rated window by a factor of ten, providing you with a conservatory that’s a stronghold against heat loss

Looks better – let’s be honest, Polycarbonate and glass roofs are not the most stylish. A proper roof blends the conservatory with the rest of the house due to its material and improves the aesthetics making it look more part of the original build and less like a greenhouse attached to the house, this is why the price of a proper roof is far greater.

Sound-proofing – Having a proper sloping roof not only insulates the conservatory, but it also helps to muffle outside sounds too. If you’ve ever struggled to hold a conversation as the rain pounds off a polycarbonate roof, you’ll know what I mean, which is why people opt for a solid roof even at the higher price.

Long-lasting – Opting for a polycarbonate roof comes with several drawbacks that you should consider:

  1. Inadequate sound insulation
  2. Poor control over temperature fluctuations
  3. Vulnerability to UV ray infiltration from the sun
  4. Susceptibility to dents
  5. Tendency to accumulate condensation
  6. Lack of resistance to scratches

 

Also, a material such as glass breaks on an existing roof and can be difficult to replace. A proper roof will outlast polycarbonate roofs significantly, with poly ones lasting about 10-15 years and a solid option around 60

Do be aware that installing a tile roof changes the original use of the structure, though and may impact your planning permission, so check this out!

Standard Double Glazing or Better?

Most new conservatories are double glazed as standard for windows, years ago many wooden conservatories would be single glazed windows, and this would be a nightmare for heat control. 

Nowadays modern conservatories and even cheap conservatories supplied and fitted have double glazing which has put a stop to this and is now a lot more energy-efficient. It doesn’t really affect the price as nearly all conservatories have double glazing.

Triple glazing

Times have changed again, and triple glazing has entered the market, a long way since standard glass. The benefit of triple glazing is as follows:

  • Noise reduction
  • Loss of heat reduced
  • Lower energy bills
  • More security
  • Value-added to your property
  • Incredibly hard to break.

While many people will still opt for double glazing in their new living space, the extra cost of a triple-glazed conservatory is worth asking about.

Self-cleaning glass

There are two kinds of this type of glass for windows, hydrophilic and hydrophobic. Both clean themselves using the droplets from rainwater however the hydrophilic option has an additional property that disintegrates organic matter using UV rays from the sun. This means it can break down dirt on the glass surface. Yes, it is more expensive than regular glass but it’s definitely worth it.

Not only do these windows keep your conservatory looking better for longer it can offer significant savings on cleaning costs on the glass. Cleaning standard conservatory windows or a bay window both inside and out can cost between £400-£500 so having self cleaning glass is extremely cost effective in the long term.

Solar or Low E glass

Low-Emissivity glass is a type of glass often found in conservatories it contains a transparent coating which improves the thermal efficiency of standard glazed window panels. It also prevents harmful UV rays.

Similar to solar glass it works by reflaxcting sunlight which prevents your conservatory becoming too hot in the summer and too cold in the winter. Chances are your chosen company will discuss, which glazing is your best option but expect to pay more for this innovative material.

Toughened glass

Standard toughened safety glass is a budget friendly option for conservatories and one you may be considering if you have a budding Ronaldo in the family. 

Safety glazing doesn’t have the energy efficiency of some options for windows we’ve mentioned but it is much more durable than polycarbonate and should last for around 15 years. Expect to pay around £50 per sq metre for 8mm thick toughened glass.

Noise-reducing glass

Acoustic glass as it more commonly known unsurprisingly reduces nose pollution, which you may be considering if you live in an urban or built-up area. It works by having layers between the windows glazing, increasing the gap between the glass and having a different thicknesses which dissipate the sound waves.

If this is an important feature for you just remember that standard timber and aluminium frames are not designed for acoustic glass, so the cost will be substantial if you have to replace all the frames too as well as the windows.

Decorative

Stained glass or decorative glass can make for a beautiful addition to traditional conservatories but these don’t come cheap even if its a small conservatory, you can expect to pay anything from £250 upwards for a small panel for a traditional conservatory and if you have a Victorian conservatory this can run into literally thousands of pounds. There are different colours and it all depends if you want slightly less light or all the light let in, this will affect what decorative style you choose.

Labour Cost

To ensure your new conservatory is built to the highest standard, you should always hire a professional tradesperson (Beware, there’s a lot of cowboys out there). Expect to pay between £150-£200 a day if you want your dream conservatory with quality doors, windows and blinds.

Material: UPVC Conservatory?

A uPVC conservatory is your cheapest option and the modern conservatory cost is reasonable with quality designs blending in with most homes. uPVC doesn’t require much maintenance but it does have a few disadvantages.

It can become brittle over time so could shatter under a heavy impact, it can sometimes look cheap and it isn’t bio-degradable so is the most unenvironmentally friendly option for a house.

However it is cheap for a bigger conservatory option with the average cost starting at around £2000

Aluminium

Aluminium conservatories are a fantastic option for modern homes or a house as they provide a chic stylish design. The materials are also incredibly strong so can handle larger window panels they can also be powder coated which gives you the option to add a personal touch with splash of colour.

An aluminium framed conservatory will be about 15-20% more than uPVC but is more durable due to the materials and requires very little maintenance.

Timber

A timber conservatory is not cheap due to materials, so how much does a conservatory cost made from hardwood and is it worth splashing the cash. The number one advantage of timber conservatories is how they look. An oak conservatory cost per square metre is eye watering with a 6m x 4m design ranging from £80,000 to £100,000.

In some situations for example an older build such as a farmhouse alumiunium or uPVC would look completely out of place.

Another advantage is there are countless options from oak wood to dark woods and you are not limited by unusual shapes or angles either. Timber wood is also easy to install, so the build may be quicker.

But before you rush to install a timber conservatory be aware that they cost more, in fact we’ve seen large luxury hardwood conservatories costing upwards of £50,000 due to materials and labour, they are also difficult to maintain needing painting and treating for wood rot regularly.

Wall / Brickwork
If you choose to include dwarf walls on your conservatory installation the average cost will increase significantly for this type of conservatory wall. The type of wall you have is worth researching as they have different benefits but walls do fluctuate in price.

Bifold doors Vs French doors?

Picking conservatory doors is difficult, Bifold doors look much better than standard glazed doors but so they should at nearly twice the price. Doors are expensive regardless so it’s important that you do your research on the doors before pulling the trigger.

Heating Options

Your conservatory will need a stand alone independent heating system or heating source separate from the house, to comply with building regulations, whether this is a electric heater or you go the whole hog and install underfloor heating is down to you but obviously this will impact the cost of a conservatory.

Underfloor heating is priced per m2 and the heat mats can cost around £20-£50 each and you’d pay extra for accessories like controls and insulation boards however it can installed easily for under £1000

Flooring Costs

Once again the sky’s the limit on this one and it’s all down to personal choice and what sort of price you have in mind for the cost of a conservatory, you can install vinyl or laminate flooring relatively cheaply for around £10 per metre or if you have one of the luxury Edwardian conservatory ranges you may prefer traditional tiles which can cost hundreds of pounds per metre square. It all comes down to your budget and what sort of costs you want to pay.

Electrical Points

Another thing to consider is how many electrical points you require and the different types. If you are just using the conservatory as a sun room it may be just one or two but using the space as a games room for the kids or an office will require more and as these can cost between £50 – £300 including labour it’s another cost of a conservatory to take into consideration.

Building Regulations - Planning Permission Requirements

Building work on large 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 conservatory with walls and other bits or it involves digging you may need a building permit. It will need to signed off for structural integrity. 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 and the construction work needed in building a conservatory.

It shouldn’t need planning permission if it doesn’t stretch farther than 0.9 metres past the wall of your property and the conservatory roof doesn’t rise above the tallest point of the property’s roof.

Fully installed conservatory prices increase depending on the time taken, so if it takes around 2-3 weeks to build a conservatory this will always be cheaper than one that takes 4 weeks.  This can increase to up to 5 weeks for a large orangery.

Selfbuild - Can I Build My Own Conservatory?

We don’t recommend building your own conservatory even though its a more cost effective option. A quick word on DIY conservatories, they are a great option if you know what you’re doing and have a DIY kit, or you have a qualified conservatory installer on hand to help. However, building a conservatory to add space is not the most popular choice if your not qualified. There are several options out there and most people will choose professionals to help them with the type of conservatory they want.

The UPVC glass windows installation needs to be done by a pro as there not straight forward and there are so many variables to take into account when installing glass, or else drafts will forever plague you. And the conservatory roof obviously will be leaking if not done correctly. Prices and costs will be lower with this option, yet so will the headaches.

FAQ’s

The average conservatory cost is usually much cheaper than an extension. Even the most popular types of conservatory are usually far cheaper than an extension. There are a lot more factors affecting an extension which is why a conservatory will cost less.

Yes, as otherwise it wouldn’t comply with building regulations

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. Awkward conservatory roofs can increase the price.

As you can see from our price guide above, UPVC conservatory prices are dependent on several crucial factors – not the least of which are the conservatory style, the site conditions and whether planning or building permits are required which all affect conservatory costs. Prices start low and gradually build up depending on the types of conservatory you want.

For many homeowners, even small conservatories are a worthwhile investment and even with a high overall price or costs, in the long run after a few years you should make your money back and more.

This guide on fully fitted prices should help you understand the different options that are available and how much does a conservatory costs in 2023.
