How much does the average conservatory cost?

Us Brits love a conservatory. My theory is because we’re big gardeners, we want to be able to be *in* it, while staying out of the rain. On top of that, it’s a great way to add a room to your home relatively cheaply. So how much does the average conservatory cost?

When buying a conservatory, there are frankly a million (well, not quite, but I do like a little hyperbole!) decisions to make which will affect the final price.

Lean to conservatory

How much does the average conservatory cost?

So how much does the average conservatory cost? Well according to LocalConservatoryPrices.co.uk a conservatory will cost you *drumroll*:

  • Around £5,800 for a lean to
  • Around £6,500 for a Victorian
  • Around £8,500 – £10,000 for an Edwardian/Georgian/Elizabethan/Regency
  • Around £18,000 – £20,000 for an orangery conservatory

What will affect a conservatory’s final cost?

When you think about the price of a conservatory, you need to think about it in m2 really, as it’s the materials (as well as manpower) that costs.

Here are some things to think about:

  • The size of the conservatory you want
  • What style do you want
  • Is there a lot of ground preparation work?
  • Why type of roof do you want?
  • What type of glazing will you choose?
  • Will you want underfloor heating?
  • What material is the frame made out of?

What is the average cost of a replacement conservatory roof?

The average cost of a conservatory roof in the UK is between £2,355 and £5,570 according to TheEcoExperts.co.uk.

This, of course, depends on your roof type and the material you use.

Conservatory roofing will deteriorate over time (like everything I suppose!) and you’ll find yourself with leaks. You may also find that the glass discolours.

Replacement polycarbonate conservatory roof cost

Polycarbonate is the UK’s most popular material to build a conservatory roof out of, because it’s relatively cheap.

The average cost of a replacement polycarbonate conservatory roof cost is around £2,355 – £2,705.

This is assuming its a lean to and 3000mm x 3500mm.

If it’s a Victorian-style (4000mm x 4000mm), a polycarbonate roof replacement will cost ou about £4,345 – £5,005.

The average cost to replace conservatory roof with tiles

On average, you can expect your tiled conservatory roof replacement to cost from around £4,000 to £6,000.

This will, of course, depend on where you live (everything will be more expensive in London for example).

Something you’ll need to consider when replacing a roof from glass or polycarbonate to tiled, is that you will be changing the classification of your conservatory from a temporary to a permanent extension.

This means that you’re going to have to contact your local council to check whether you need to apply for planning permission. This currently costs £462 to do.

What’s the average cost of a glass conservatory roof?

Glass conservatory roofs are the most popular type. If you want to replace a conservatory glass roof, you’ll be looking to pay around £2,610 for a lean to, £4,740 – 5,345 for a Victorian and £5,305 – £6,0101 for an Edwardian conservatory.

How much does a small conservatory cost?

Again, this depends on the materials you use and the type of conservatory – but it’s useful to know what a small conservatory size is according to the industry.

Typically that’s anything below 4000mm x 4000mm.

How much does it cost to clean a conservatory roof?

Sometimes when a conservatory roof gets old, it can start to look grotty and discoloured. Rather than running straight to replacing it, you could get it professionally cleaned.

In fact, if you get it cleaned and maintained properly, you may find it lasts longer.

So how much does it cost to clean a conservatory roof? Well, of course, you can clean it yourself for free. You have to be very careful though, not to damage the conservatory in any way -making sure you buy the right products is the right place to start.

If you want to get professionals in, it depends on the size of the conservatory and the what sort of service you want.

For an average-sized conservatory, you’ll be looking to pay from around £150 for inside cleaning only and £300 for both inside and outside cleaning.

Full valet service prices come to around £650 (ouch!), but it might save you money in the end by keeping it in good condition.

How much does it cost to insulate a conservatory roof 

Lining a conservatory roof with insulation should cost around £35, or less per sq m2 (though some companies will try and charge you more).

For instance, a lean to 4 x 3 conservatory is normally £450, fitted and installed, whilst a larger Victorian type conservatory with lots of cuts and detailed work will cost around £900.

Consider asking a local joiner or plasterer to do this as it will save you an arm and a leg.

Always get three estimates and never sign up there and there. Insist on a 7-10 day cooling-off period so you can check prices and not rush into any decisions.

Where to find conservatory cost calculators?

A conservatory cost calculator is a good way of estimating the price of a conservatory, as you can stick the size you want, and the materials and it will tell you the cost.

Probably every company who offer conservatories will have their own calculator on their website, but it’s worth trying at least three different calculators to see how the prices vary.

Here are a couple that will give you a number without you needed to talk to a salesperson.

How much do conservatory blinds cost?

Getting some blinds for your conservatory is necessary if you want a bit of privacy, or want to be able to control the temperature within the structure somewhat.

When it comes to conservatory blinds for the windows, there are loads of options when it comes to looks, practicality and budget.

Vertical conservatory blinds cost the least because one verticle blind can cover several windows, up to a maximum width of five metres.

Depending on the shape and size of your conservatory, you may only need four or five blinds to cover all of the windows, and the fewer blinds you have the cheaper the cost of your conservatory blinds.

The fabric you choose for your blinds is really important. Not just price-wise, as some materials are more expensive than other, but also, the darker they are, the more heat they’ll absorb and the hotter your conservatory will be.

Ideally, you’ll want a light coloured fabric with a reflective backing to keep it as cool as possible.
