A Detailed Look at Conservatories and How Much You Should Pay

Are you considering having a conservatory built? Do you want to know how much it should cost? We are aware of how much conservatory companies charge in the UK because we asked many of them to quote us. The team here at Quotation Check gathered conservatory prices in December 2016 and on this page, you will find the average cost of an installation.

Don’t forget; this is just one of many price guides we have created during the last two years. See our full price list here.

A Reminder From the Team Here at Quotation Check

During the last two years, the team here at Quotation Check has been gathering quotes from tradespeople and companies in the UK and displaying an average price via our price list.

You should be aware of one caveat, though.

Companies that sell big-ticket items such as conservatories and Upvc windows often employ sales people.

The price paid for a new conservatory won’t just depend on where you live, the size and specification chosen or even the time of year (more about that later so keep reading) but will depend on how well you haggle.

To Give You an Example:

One very well known national company quoted us an initial figure of £17000 before applying various discounts and offers as we haggled and negotiated.

From “Winter discounts” to “first customer on your street” price reductions and various unpleasant tactics to rush us into accepting the offer.

The final price we were offered?

£12000.

That is a reduction of £5000 – something you may or may not achieve yourself.

In addition to comparing a minimum of three conservatory quotes, we also encourage you to check out our poll (further down the page) into how trustworthy tradespeople in the UK are.

Extra You’ll Probably Want to Consider

The prices displayed below are based on a standard conservatory installation, they do not include extras that you may need or want. Either all or some of the following charges will apply to your installation:

  • Glass roof panels instead of polycarbonate – The price varies upon the size of the roof, the type of glass and the installer but the companies we contacted suggested price increases of between £1250 and £4500, the most expensive option being for higher specification thermal reflective glass.
  • Brown woodgrain effect finish  – Instead of a standard white trim, expect this to cost an extra £1750 to £3000 (this was just a rough guide given to use by several of the salespeople, not firm quotes)
  • The number of window openers also affects the price – We chose one small opener and one large opener per side of the conservatory.
  • Roof Windows – We chose one roof window but could have chosen more at extra cost.
  • Air conditioning units – to keep the conservatory at an ideal temperature all year round. These can vary in cost but expect to pay several thousand for a discreet and silent premium product.
  • Wall knock through – removing part of a wall and installing a door into the house, not every house needs this as some houses already have a patio door. Expect to pay several thousand for the labour, the steelwork to support the wall above, making good the plaster on the inside and the sliding patio door itself.
  • Bi-fold doors – These are a popular option but come at a price, from £1750 for a budget door up to £6000 for a premium product.

We didn’t ask about flooring and blinds so don’t have a guide price for these items.

Ballpark Figure for a Premium Installation:

Assuming you want all the extra items with your conservatory, use this calculation as a rough guide for a 4m x 3m installation:

Standard installation – £12500

Thermal glass roof – £4000 (self-cleaning options can cost even more)

All Windows to have openers – £1000

Maximum number of roof opening windows – £1000

Wall knock through, lintel to support upper wall and sliding door installation – £2500

Bi-fold door mid-range – £2500

Air conditioning unit £1500 (supply-only, these units cost from £500 for a cheap one and up to £1400 for a premium product)

Total Cost: £22500 (excludes blinds and flooring)

As you can see from our price guides on this page, the cost of a standard installation can be quite low but when the extra costs are factored into the quote, the price can easily double.

How do our Figures Compare to Others?

A recent survey of 269 people by the consumer group Which? revealed the average cost of a conservatory was £12000.

22% of those surveyed paid between £5000 and £10000, 25% paid between £10000 and £15000 while 14% paid between £15000 and £20000.

When Were These Prices Updated?

Outdated and irrelevant prices can be very frustrating. That is why we intend to update our full price list every two years at least.

This conservatory costs listed on this page were last updated on the and are based on quotes we gathered in early December the previous month.

Victorian Vs Lean-to

The two conservatory price examples shown in the table above are for the most popular conservatory styles in the UK – a straightforward and affordable lean-to and a more classic Victorian style.

Victorian Style

Both of our prices include the following:

  • Clear and prepare the ground
  • Install footings and concrete base (foundations for the conservatory)
  • Lay a dwarf brick wall – usually ~1metre in height
  • Install the Upvc windows and doors
  • Roof installation – Upvc trim with polycarbonate plastic panels
  • Electrical work – light and sockets
  • Plastering and painting

How Long Does a Conservatory Build Take?

The companies we chose gave us varying timescales and bear in mind we did speak to salespeople whose goal is to sell us a product, even if that means being very optimistic with build times.

Here is what we know about building a conservatory:

  1. Full site survey (different from the salesman’s measurements) – within a week.
  2. Planning application and acceptance (not always required) – 1-4 weeks.
  3. Construction of conservatory in the factory – 1 month in winter and up to 3 months during the busy summer period.
  4. Preparation of ground, digging out the foundations, etc. – 1 day.
  5. Laying foundations and base – 1 day.
  6. Construction of small brick wall – 1-1.5 days.
  7. Installation of the conservatory inc roof, leadwork to the wall, rainwater guttering, etc. 1 -1.5 days.
  8. Electrics, wall plastering and sils- 1 day.

Cement and brickwork will need time to dry/harden so expect a delay between different tradespeople being on site.

As you can see from the guide above, the actual installation of the conservatory doesn’t take too long, but the preparation work does.

Can You Get a Better Deal in Winter?

The winter months are the quietest for window companies, roofline fitters and conservatory installers.

Based on our experience in the trade and the last two years of researching prices for Quotation Check, we believe you can make a saving during the quiet season.

Obviously, you will need to negotiate hard, and every company will have a different policy, but we know from experience that many traders have shorter waiting periods during the winter.

The summer is when waiting times can reach several months, and you are less likely to get a great deal.

The bottom line is this; when companies have few projects on their books, they often reduce the prices just to keep their best employees from going elsewhere.

One Response to “A Detailed Look at Conservatories and How Much You Should Pay”

    Help needed. We have been given a quote for a Lean to conservatory from CR Smith. The size is approx. 5m x 2.75m x 2.1. I set of double doors. A sliding door from the kitchen into conservatory and a new kitchen window approx. size 1.5m x 1m. Also a firewall will need to be built 2.75m x 2.1m. We are not getting blinds supplied or tiles fitted by them, they are installing 3 power points and 2 light fittings. Also a climate control unit comes as standard with the conservatory, we said we didn’t want one, but were told it comes as standard and that the price of the unit cannot be knocked off the quote. We are not replacing a conservatory, so I dare say foundations will have to be installed. Conservatory is floor to roof glass, with polycarbon roof, we don’t want a dwarf wall. We were quoted £28100. at first, when we said that was more than what we prepared to pay the quote suddenly dropped to £27100. We still think that the quote given is still far far too high. Any help would be appreciated.
