What could affect my conservatory cost?

How much does a conservatory cost? That all depends on what you need.When setting up a new conservatory, you’ll need to think about more than just the glass. Building a conservatory is always a bespoke job, which means there are often ballpark figures to keep in mind as far as prices are concerned.

However, the great news is that you can learn more about how much your conservatory will cost by looking at the variables. It’s easy enough to think that lean to conservatory prices will be lower than a more advanced conservatory style. But, think about conservatory roofs, underfloor heating, the amount of living space you’ll need, and where you want to install your conservatory. It all adds up!

Essentially, you’re not only paying per square metre for your new conservatory, you’re paying for materials used, tools needed, and labour time, too. It’s the same as any other building project.

Here’s a list of what can and will make conservatory prices go up and down:

  • Your conservatory roof (style, pitch, size)
  • Glazing options (glass type, finish, double glazing, etc)
  • Conservatory style (dwarf wall, lean-to, Edwardian, Victorian, etc)
  • Build materials (e.g. is it a UPVC conservatory)
  • The size of the conservatory
  • Flooring choices
  • House wall openings
  • Planning permission (if you need planning permission for your conservatory, expect cost around
  • Added extras (such as underfloor heating, electric points, etc)

That’s why it’s always best you look for bespoke quotes from several providers before you go ahead and make a purchase. If you ask one conservatory installer ‘how much does a conservatory cost’, chances are you’ll get a very different answer from the next. That’s why looking for at least three quotes, to build an average, always pays dividends.

 

Have you budgeted enough for your new conservatory?What is the average cost of a conservatory?

As mentioned, average sized conservatories in the UK are likely to cost between £15,000 and £20,000. However, to be more precise, we need to consider the size of your installation, as well as the style. So, let’s break this down further!

 

3×3 average conservatory cost

3×3 conservatories tend to be on the smaller side of the market. Therefore, it’s worth looking at their average prices to see what your opening costs are.

You can expect to pay between £1,700 and £2,700 per square metre for a 3×3 conservatory. 3×3 conservatories are nine square metres in size (on average), so you can expect to pay at least £15,300 at these rates.

That’s based on the industry average in the UK right now. It’s not accounting for wall openings, or any other facets and flourishes you might expect from a more advanced type of conservatory.

We’ll take a look at the average costs of different types of conservatory a little further down.

 

4×4 average conservatory cost

4×4 conservatories are the midpoint option when it comes to installing a conservatory at home. These options tend to be great for summer houses, garden offices, playrooms and more. They give you a lot of space, and while they’re not the biggest available, they’re more than roomy enough for most people.

4×4 conservatory prices tend to fall around the £1,500 to £2,000 per square metre mark. There are 16 square metres to account for, so that means you can expect a 4×4 conservatory to cost you £24,000 at least.

Again, this is an industry average. You may expect to pay more for a solar glass conservatory, for a tiled conservatory roof, or for a particularly stylish Victorian conservatory. However, that’s the benchmark.

 

6×4 average conservatory cost

So – how much does a conservatory cost if you’re looking at the bigger end of the market? 6×4 conservatories tend to be the biggest choices from most conservatory installers in the UK. There’s 24 square metres to account for here, so on size alone, you can expect to pay much higher than the 3×3 and 4×4 averages.

6×4 conservatory prices average between £1,200 and £1,700 per square metre. That’s lower than you’d pay per metre for 3×3 and 4×4. However, you’re paying for a bigger conservatory overall, so this adds up to at least £29,000 at the lower end of the scale.

Bigger conservatories may also arrive with more features and grander flourishes than their smaller counterparts (though that’s not always a given). You can expect additional features such as a tiled roof, timber frames, etc to add to the final invoice.

The average cost of different conservatory styles

With the above in mind, let’s consider different styles. How much does a conservatory cost if you’re just setting up a simple dwarf wall? Can you expect to pay more for an Edwardian conservatory with a tiled roof, over a lean-to conservatory with a simple, glass roof?

Again, we need to consider the industry averages. Yes, it’s easy to think that a conservatory with dwarf walls is going to be cheaper than your more complex p-shaped conservatories, or grand garden offices.

Let’s take a look at some different styles, and what you might expect to pay on average, based on uPVC and 3×3.

A lean-to conservatory

 

Lean-to conservatories

The average cost lean to uPVC conservatories are likely to demand will be around £6,000 to £8,000, fully fitted. Again, this is 3×3, so the smallest and simplest on the market.

A lean-to conservatory installation is likely to be the simplest available. These are very clean conservatories that generally serve as an extension to a kitchen or living room. However, they are massively popular across the UK, with with a low cost around the £6,000 mark, they tend to be a good choice if you just want a bit more than just windows to look through.

 

An Edwardian conservatory

 

Edwardian conservatories

The average cost of an Edwardian conservatory in uPVC is likely to be around £9,000 to £12,000. That’s fully-fitted, and at its smallest.

Edwardian conservatories are very popular across the UK for their simple, rectangular looks and clean lines. You can choose a variety of different glass options and roof styles for an Edwardian project, and they tend to work really well as sun rooms and garden offices. Naturally, if you want a fancier frame or tougher material, you’re going to pay more.

 

A Victorian conservatory

 

Victorian Conservatories

You can expect to pay an average of £9,000 to £12,000 for a Victorian conservatory, based on uPVC and at 3×3 sizing. There generally isn’t much difference in the conservatory costs between Victorian and Edwardian.

However, Victorian conservatories can look much different from their Edwardian cousins. They tend to have bay window fronts and can often be more ornate and stylish. You’ll normally be able to tell a Victorian conservatory from its roof – normally high pitched, with stylish decoration.

P-shaped conservatories

You should expect to pay between £9,000 and £12,000 for a P-shaped conservatory, with uPVC and 3×3 taken into account.

P-shaped conservatories give you the best of all worlds. They tend to be great choices for those in need for a bit more space to move around in, and as you can expect, they’re shaped like the letter ‘P’. They’re often a good choice in the mid-ground between Edwardian and Victorian styles, if you’re really unsure.

 

L-shaped conservatories

L-shaped conservatories are likely to cost between £12,000 and £15,000 at 3×3 with uPVC. This is where you start to pay a little more for the size, not just for the materials used.

Again, L-shaped conservatory installations are pretty simple to explain. They’re shaped like the letter ‘L’ – granting you even more floor space than you’d expect from a ‘P’ shape or a lean-to.

 

T-shaped conservatories

T-shaped conservatory prices start at around £12,000 and peak at around £15,000, providing it’s a 3×3, and you’re using uPVC. There shouldn’t be that much difference in cost between Ts and Ls.

That, again, is because the sizing is fairly similar. You’re paying for a conservatory that’s more than just a simple square or a window box! Consider these conservatory styles if you’re in need of extra room than the average.

 

Ever thought about setting up an orangery?What about orangeries?

You will expect to pay around £16,000 to £60,000 for an orangery. That’s because orangeries include additional brickwork, and generally fill that gap between conservatories and full extensions.

Although a wide range of conservatory styles will likely support you if you’re looking for a simple garden room or a sunroom, orangeries work really well as rooms that blend into the look and fit of your building.

However, they are more expensive – and that’s before you consider anything fancy such as sun glazing, tiled roof options or even a dwarf wall.

 

Will I have to pay for planning permission?

You’ll only have to worry about paying for planning permission if your conservatory is bigger or taller than the recommended dimensions, or if it’s three metres beyond the back wall of your property (it’s sometimes four metres depending on your property type).

Here’s a quick checklist – if your conservatory doesn’t tick any of the following boxes, you probably won’t need to get permission.

  • Is your conservatory smaller than 4 metres tall? (This may defer to 3 metres in some cases)
  • Does your conservatory reach more than 6 metres to the back of your home? (8 metres in some cases)
  • Are you building your conservatory to the front of your home, or facing the main road?
  • Does your conservatory take up more than half of your building’s land?
  • Is your conservatory the tallest point on your house?
  • Is your conservatory more than half the width of your property?

Chances are, you won’t have to worry about the cost of conservatory planning permission if none of the above applies.

Otherwise, you may expect to pay around £200, at least, to get ‘full permission’ to set up your conservatory. In most cases, an installer or conservatory builder worth their salt will help you with this!

 

Conservatory material costs

If you’ve been following our guide so far, you’ll have noticed that we’ve generally used uPVC as the based material for the average conservatory cost. That’s because it is, by and large, the cheapest material to work with. That doesn’t make it any less protective than the average, however, there are definite benefits to choosing more expensive materials and builds.

Other conservatory materials available include aluminium and timber. Let’s take a look at each of these in turn, and consider the average cost.

 

Aluminum conservatories

The bigger the windows and the grander the glazing, the more likely it is you are going to need an aluminium style of conservatory to support your glass. Aluminium is highly sought-after because it’s tough, it’s durable, and it’s better at locking in the heat. On top of that, it has low energy emissions, and it’s endlessly customisable.

Aluminium is also impressively low-maintenance. You won’t have to keep it as clean as uPVC frames, meaning that if you’re looking for a stylish look that’s relatively undemanding, it’s probably going to be a good choice. However, as you can imagine, this convenience and flexibility are always going to boost your conservatory costs.

This material is likely to cost you around 26%-30% more than you’d pay for a uPVC conservatory in the same size and style. So, with the above costs calculated above, just add this to the top if you’re interested in a metal finish.

 

An impeccable timber conservatory

Timber conservatories

Timber conservatories really do look incredible, making it hardly surprising that they often demand the highest installation costs. That’s regardless of how your conservatory or extension is glazed, and no matter what you intend to use your space for.

Timber frames for conservatories are popular with homeowners who may be looking for bespoke flourishes or styles. These conservatory options also tend to work brilliantly with period property, where you’re unlikely to want anything too modern or clean to stick out like a sore thumb.

That said, timber conservatories are both the most expensive on the market, and tend to require the most care and attention. Unlike uPVC and aluminium, you are going to need to keep painting and finishing your frames so that they don’t spoil or rot with the weather, or through years of use. Providing you have the money available and are willing to put the time in to care for it, a timber conservatory adds incredible value to a property.

So, how much is a conservatory with timber frames? You’re looking at around 50% additional cost to a uPVC base price. This is an average expectation, and as you can imagine, it doesn’t include extra conservatory costs (such as a dwarf wall or roof options).

Conservatories can arrive with all kinds of roof styles

Conservatory roof options

Yes, even your choice of conservatory roof may add to the overall price you pay. To begin with, if it is complex enough, you may need to hire an additional roofer to come and install everything for you – that’s around £200 per day, on average, and even a small conservatory will cost extra if your roof is fancy enough!

Conservatory roofs tend to come in three styles – polycarbonate, glass and tiled. Let’s look at each in turn.

 

Polycarbonate roof costs

Polycarbonate roof installations have come a long way in the past few years, and they tend to be a great entry level option for conservatory roofs. Polycarbonate roof installations will likely cost you at least £2,700, with costs likely to peak at around £7,200. These are costs based on replacement prices. What increases the cost here is the style and complexity of your conservatory.

Polycarbonate is great at blocking the worst rays from the sun, and it’s nice and light.

 

Glass roof costs

Glass roofing will add more to your conservatory cost than polycarbonate, and again, much of it is dictated by the complexity of your installation. A pitched roof with Victorian flourishes, for example, will likely drive up the costs.

Based on replacement costs, you can expect to pay anywhere between £3,000 and £8,000 for a glass roof. Glass roofing tends to be tougher and more resilient than polycarbonate, and many people prefer the look. However, it is much heavier, and will need reinforcing.

 

Tiled roof costs

Tiled roof installations will cost around £8,000 minimum (at 3×3) anywhere up to £20,000 for the biggest or most complex jobs. This is a type of roof that will protect you against the elements, however, and will help you blend your conservatory wonderfully with the rest of your outer building.

A tiled roof is also great at locking in heat. However, you may need to account for tradesperson costs, which could add more to the overall bill. Tiled roofing will also prevent you from looking up into the sky on clear days – so think carefully about what you really need and want from your perfect conservatory!

 

Conservatory Glass Costs

You'll need to budget for double glazing if you want to keep warmConservatory costs will increase further when you consider different glass options and styles. We don’t just mean a glass roof, either. The cost of a conservatory will increase if you choose sun-protective glass, for example, or if you need your glass toughening.

The average conservatory cost guides we’ve arranged for you in this article will, on the whole, take into account some glazing. However, you’re probably likely to find this glass to be A or B rated. A is great – but A++ is better.

Triple glazing is likely to add more to your conservatory cost, and these rates will vary from provider to provider. This is where you are most likely to get your A++ energy rating. Double glazing, on the other hand, is probably likely to get you anywhere between A and A+.

Here’s a quick rundown of the other different options available.

 

Low E glass

Low E glass is fantastic at helping to reduce the amount of heat that your conservatory absorbs. This means it’s going to deflect much of those harmful rays from the sun, helping to moderate temperature across all seasons. It’s great against glare, too.

Sometimes known as solar glass, you can expect this glass style to increase conservatory prices by around 30% on average.

 

Coloured glass

Coloured glass is an optional design choice that will help you to tie the look of your conservatory together. Too much decoration can be distracting, so be sure to discuss the right balance with your installer.

You must make sure you absolutely want this extra – as it could well add between 50% and 60% to your overall conservatory cost.

 

Self-cleaning glass

Yes! There is such a thing as self-cleaning glass, and while you will still probably need to wipe it down occasionally, this glazing is built with an inner compound to prevent water staining and dirt clinging to your outer glass.

Be sure to add anywhere between 20% and 30% onto the overall conservatory cost if this is something you’re looking for.

 

Noise reducing glass

Acoustic glass can be a real relief for many homeowners, and while it can increase the cost of a conservatory by around 30%, it makes the difference if you want a quiet office or entertaining space if you live in a busy area.

 

Toughened glass

Toughened glass is an absolute must if you’re worried about breakages, and it tends to be a safer choice than the average in most cases. It’ll boost conservatory prices by around 25% – 30%, but it’s probably worth it!

Do I need to pay for additional tradespeople?

Sometimes, yes, you may need to pay for additional tradespeople if your conservatory demand is complex enough. However, the best conservatory installers should offer you an all-in-one cost depending on the scale of your project. That, again, is another great reason why it pays to look for at least three different installers in your area.

You may need to factor in installation costs for electricians, flooring installers, glazers, roofers and heating engineers. Be sure to discuss these concerns with your chosen conservatory installer before you go ahead and set your budget.

 

How much does a conservatory add to value of a house?

A conservatory can certainly add value to a property. Depending on where you live, you might expect to add up to 12% to the sale price of your home. However, somewhere closer to 4% is more likely.

However, do keep in mind that you must ensure your conservatory is set up by professional installers. A poorly-installed extension, regardless of conservatory cost, is going to undo a lot of value.

So, those additions to conservatory prices listed above may well be worth it, especially if you already live in a high value area or have a big enough property!

 

Other conservatory costs you might wish to consider

Let’s take a final rundown of some of the extra conservatory cost points you might want to think about before you set your budget.

 

Dwarf wall

In many cases, you’ll need to support your conservatory with brickwork. A simple dwarf wall is recommended in these cases, and you’ll need to account for up to £350 per square metre.

 

Blinds

Want to install stylish blinds for your conservatory? The conservatory costs here will likely reach around £100, maximum, though it does depend on your installer and the types of blinds you are looking for.

 

Guttering

This is something usually included in your overall conservatory cost, but it is always worth keeping in mind – your conservatory is always going to need to drain away. So, expect conservatory prices to leap by around £20 per metre, max, for guttering.

 

Heating

The amount of heating you’ll need in your conservatory will obviously depend on your style and your material used. You might not need extensive heating installed if you have an aluminium build, for example. Underfloor heating and radiators will vary in cost rather wildly, so be sure to enquire with your installer on overall conservatory prices with warmth in mind.

 

Wall opening

Most conservatories will stand alone with glazed walls, however, some people choose an open plan style instead. By removing walls, you’re likely to pay more for labour in your conservatory costs.

 

Flooring styles

Looking for tile, stone, lino or otherwise? The type of stone and the size of your floor plan will add to the cost when building a conservatory. The more durable the material, the higher the prices – the same with a conservatory roof.

 

Electricity

Electrical points are also likely to add to conservatory prices – but the exact cost will depend on what you need. make sure to discuss in detail with your installer!

 

Conclusion

How much is a conservatory? Good question!

The average conservatory price, as you can see, is always going to vary pretty wildly! From your conservatory roof to your floor – and everything in between – there is a lot to balance.

However, this is just a general guide – you might be able to grab yourself a bargain on a great uPVC conservatory or a stylish glass conservatory roof if you find the best installer.
