Fully Fitted Conservatory Prices & DIY Installation Cost Guide

We deep dive into the costs to build a conservatory and the prices you can expect to pay 2022. Below we cover everything from materials, to supply only and cost of installation.

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 can be anything from £4,000 to ten times that number. The average fully fitted conservatory cost in £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 cost on the value of your home.

Rough Conservatory Costs (Supply and Install)

A written quote for the supply and full installation, including any extras mentioned, is what you want before agreeing to anything. With conservatories, prices, including installation, are usually standard but do your checks.

Below, we’ll take a closer look at the design features and typical fully fitted conservatory construction costs.

Types of Conservatories

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

Lean-to conservatory prices

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

A Lean-to 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, 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 and glass conservatory or if you are searching for cheap conservatory prices.

Edwardian conservatory prices

The average conservatory cost of an Edwardian 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. They are usually built with a small brick wall and installed with a polycarbonate glass roof as standard.

Georgian / Hipped back conservatory prices

The average conservatory cost of a hipped back Georgian fitted is £8000 – £11500.

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. One 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.

Victorian conservatory prices.

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

One of the period conservatory types can be found in rural or urban homes. These particular models are sometimes referred to as sunrooms as they provide a rounded appearance with a high conservatory roof.

Gable conservatory prices.

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

The Gable is characterised by its vaulted glass-panelled conservatory roof. The glass panels allow for maximum natural light and enhance the design’s bright, airy feel. These conservatories make great sunrooms and pool enclosures.

P-shaped conservatory prices

The average conservatory cost of a P-shaped style 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 conservatory prices

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

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 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 an existing conservatory to an orangery.

Small 3x3 conservatory 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 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 lean-to conservatory can cost 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 prices

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 choose will influence the conservatory costs, with a timber conservatory or orangery with tiled roofs topping the list.

Conservatory Cost Factors

Below we will look at the individual sections of the project and where your money will be spent.

Size of conservatory / floor plan

The conservatory size that you choose will have the most significant impact on the price bar none. Conservatory prices are worked out based on a square metre and 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 allow, I recommend going more extensive than this shoebox size.

What is the average size of a conservatory?

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 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 involves an extra cost, so speak with a contractor about whether permission will be required or not.

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 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 can remain a lot of the time.

Do you need foundations for a conservatory?

Yes, like any extension, a conservatory does need foundations to keep the structural integrity of the build. These should be at least 600mm 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.

Roof type

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 is a lot more expensive.

Polycarbonate glass roof

A polycarbonate roof is the first option that most conservatories come with; they are low cost and cheaper 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.

Can a conservatory have a solid roof?

Yes, a 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 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.

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 and improves the aesthetics making it look more part of the original build and less like a greenhouse attached to the house.

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.

Long-lasting – One of the biggest disadvantages of a glass and polycarbonate conservatory roof is that they are easily damaged and can suffer from mould or excessive condensation.

Also, glass breaks 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!

Glazing Type

Standard double glazing

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.

Triple glazing

Times have changed again, and triple glazing has entered the market. 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, 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 does this keep your conservatory looking better for longer it can offer significant savings on cleaning costs. Cleaning standard conservatory windows 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. 

It doesn’t have the energy efficiency of some options 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 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.

Decorative glass

Stained or decorative glass can make for a beautiful addition to a traditional conservatory but these don’t come cheap you can expect to pay anything from £250 upwards for a small panel and if you have a large Victorian conservatory this can run into literally thousands of pounds.

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

Conservatory Material


A uPVC conservatory is your cheapest option and the modern designs blend 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

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


Aluminium conservatories are a fantastic option for modern homes as they provide a chic stylish design. This material is 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 and requires very little maintenance.


A timber conservatory is not cheap, 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.

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 to dark woods and you are not limited by unusual shapes or angles either. Timber 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 costig upwards of £50,000, 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.

Door Choices

Bifold doors Vs French doors?

Bifold doors look much better than a standard glazed door but so they should at nearly twice the price.

Heating Options

Your conservatory will need a stand alone 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.

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


You will need guttering to drain away rainwater and this will cost between £10 – £16 per metre

Flooring Costs

Once again the sky’s the limit on this one and it’s all down to personal choice, 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.

Electrical Points

Another thing to consider is how many electrical points you require. 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 to take into consideration.

Building Regulations

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 conservatory you may need a building permit. It will need to signed off for structural integrity. 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 the conservatory roof doesn’t rise above the tallest point of the property’s roof.

Where Do I Find Reputable Conservatory Installers?

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.

National Conservatory Companies or Local Firms

Seriously do yourself a favour and go with the local guy. Check the reputation and get a fair fully fitted conservatory quote from an approved installer. No need to pay over the odds for some big national companies branding and overheads.

How many conservatory quotes should I look to get?

When making an enquiry, you must have a list of all the conservatory questions you want to ask and go to at least 3-to 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.

Will I need one conservatory company or multi tradespeople?

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.

How long does it take to build a conservatory?

It takes around 2-3 weeks to build a conservatory although this can increase to up to 5 weeks for a large orangery

Should I pay a deposit or anything upfront for the conservatory?

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.

Guarantees and Warranties

Reputable conservatory companies will always provide comprehensive warranties included in 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 quote.

Always make sure if your going fully fitted that the conservatory price you get includes an extensive warranty, and if possible, you want independent insurance backed guarantees.

Selfbuild - Can I Build my Own Conservatory?

We don’t recommend building your own conservatory.
A quick word on DIY conservatories, they are a great option if you know what you’re doing, or you have a qualified conservatory installer on hand to help.

The UPVC windows installation needs to be done by a pro, 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.


The average conservatory cost is usually much cheaper than an extension

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

Yes you can add a conservatory to the front of your house as long as it doesn’t take up more than 50% of the garden

A conservatory needs to be within 2 metres of the boundary

On average cleaning the exterior of a glass conservatory can cost about £125.

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.

This guide should help you understand the different options that are available and how much a conservatory can cost.
