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.

Here’s a quick checklist – if your conservatory doesn’t tick any of the following boxes, you probably won’t need 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 dream conservatory. In most cases, an installer or conservatory builder worth their salt will help you with this!

Conservatory roof options

Yes, your choice of conservatory roof may add to your overall price. 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 glass roofs come in three styles – polycarbonate, glass and tile. 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

When it comes to conservatory cost, glass roofing is a pricier option than polycarbonate. The complexity of your design, such as a pitched or Victorian-style roof, can drive up the replacement costs.

For a standard glass roof, you’re looking at a range of £3,000 to £8,000. While it’s tougher and adds natural light to your main room, it’s also heavier and will need reinforcing.

If you’re considering a gable conservatory with conservatory doors, the costs can vary. A sloping roof might be more straight but remember, so many factors can affect the final price. Whether it’s a cheap conservatory or an extension that matches your house, the choice is yours.

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 type of roof will protect you against the elements. However, an attractive finish will help you blend your conservatory wonderfully with the rest of your outer building.

A tiled roof is also great at being energy efficient, 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 need and want from your perfect conservatory!

Conservatory Glass Costs

Choosing different glass options will bump up your conservatory cost. Sun-protective or toughened glass costs more than standard glass.

Our average cost guides factor in some glazing, usually A or B-rated. But if you want top-notch energy efficiency, go for triple glazing.

This could get you an A++ rating, while double glazing usually lands between A and A+.

So, what’s the takeaway? If you’re upgrading an existing conservatory or planning a house extension, the type of glass you choose makes a huge difference in fully-fitted conservatory prices. Whether you’re into traditional conservatories or eyeing large conservatories with solid oak frames, the glass choice is straightforward but crucial.

Low E glass

Low E glass is fantastic at helping to reduce the amount of heat that your conservatory absorbs. This means it will 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 style to increase conservatory prices by around 30% on average.

Coloured glass

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

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

Self-cleaning 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. 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!

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 consider before setting 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.

Interior Blinds

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


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


The heating you’ll need in your conservatory depends on the material and style you choose. For instance, an aluminium build might not require much heating. Costs for underfloor heating and radiators can differ, so factor this into your overall conservatory prices when talking to your installer.

Wall opening

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


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

Conservatory planning permission


How Much Value Does a Conservatory add to a House?

Adding a fully fitted conservatory can increase the value of your home by around 5% to 7%. However, conservatory prices and the value they add can vary depending on factors like, which frame and whether you opt for features like double-glazed windows or a solid roof.

How Long Does It Take to Build a Conservatory?

The construction work for a conservatory varies, but you can generally expect it to be completed in 12 to 14 weeks. This timeframe can differ based on the complexity of the design and any additional features like French doors or a dwarf wall.

What’s the Best Material for a Conservatory?

Choosing the best frame material for your conservatory depends on your needs. uPVC is an affordable option, aluminium offers a sleek and modern look, while timber provides a traditional, bespoke style. Each material has its own set of conservatory prices and maintenance requirements.

Can I Use My Conservatory Year-Round?

Absolutely, with the right temperature control features like underfloor heating and noise reduction options, you can enjoy your new living space all year round. Modern conservatories often come with options for solid roofs and standard glass that enhance structural integrity and make the space comfortable in any season.


So, you’ve ventured through the labyrinth of conservatory costs, from the intricacies of uPVC conservatories to the elegance of glass conservatory roofs. The takeaway? The average conservatory price is a bit like a chameleon—always changing based on a myriad of factors.
