Our conservatory cost guide including what affects the price of conservatories most


Including all materials and installation, typical conservatory prices in the UK average between £5,000 and £20,000. However, it’s important to understand that the final quote will largely depend on a range of factors. Carry on reading to find out what these are and make sure you’re 100% certain that you’re getting value for money to build the conservatory of your dreams with ease.

Top 3 ways to find the best conservatory prices

1.       Conservatory installer

The calibre of your conservatory installer should be your number one consideration.  Industry accreditations and memberships provide peace of mind that a double-glazing company is reputable, skilled and conscientious about providing the best price and service first time round. As well as the overall price, if, for example, a glazing company cuts corners on essential planning consent on your new conservatory, it could mean further unnecessary costs further down the line to remedy the issue. So, before obtaining at least 3 separate quotes, be sure to look out for the following trust signals:

  • 10-15 year insurance-backed guarantee on parts and labour
  • Glass and Glazing Federation membership (GGF)
  • TrustMark registration
  • CERTASS CQ-Assured Conservatories and Conservatory Warm Roof Scheme certification
  • Chartered Trading Standards Institute approval (CTSI)
  • The Glazing Arbitration Scheme registration (TGAS)
  • The Master Window and Conservatory Installers Association membership (MWCIA)
  • Which? Trusted Trader membership
  • Checkatrade membership
  • Trustpilot membership
  • FENSA approved installer

Although a FENSA certificate isn't needed for a new conservatory, FENSA registered companies are regularly assessed to ensure their work complies with the latest building regulations.

Getting a range of quotes from a mixture of national and local installers will also play a key role in conservatory prices, as local installers can work out considerably cheaper than their national rivals as their overheads are generally much lower.

2.       Conservatory materials

You may love the idea of a natural timber conservatory, but you might not like the price tag attached! Out of the three main materials available, uPVC conservatories are the most affordable, followed by aluminium conservatories and then timber conservatories. This is because uPVC is much quicker and easier to produce. But don’t forget that better quality conservatory materials will last longer and are more likely to add value to the property, and, therefore, your new conservatory may very well pay for itself when it’s time to sell-up.

The type of conservatory roof notably influences conservatory prices too. Polycarbonate roofs are at the lowest end of the pricing scale, followed by classic glazed roofs, solid tiled roofs, tiled roofs with rooflights and then illuminating roof lanterns.

3.       Conservatory size / finish

The size of your new conservatory goes hand-in-hand with your chosen material – the bigger the size or the more complex the design, the higher the price. Lean-to style conservatories often work out the cheapest, as they have three walls that ‘lean’ against the existing wall of the building, so they require less materials and labour to build. Whereas P-shape or T-shape conservatories are much larger, and therefore more expensive. You could opt for a smaller custom-built conservatory, however a bespoke design is likely to increase the price. Conservatory add-ons and upgrades like dwarf walls, cornices, internal pelmets, lighting, heating, crestings and finials, gutters and roof vents will also push up the price.

Of course, finishing touches will significantly affect conservatory prices too. Coloured uPVC, woodgrain effects, powder coated and marine grade finished aluminium, and specialist micro-porous paints, stains and varnishes for timber all add up.

What else can affect conservatory prices in the UK?

Conservatory glazing

Utilising swathes of crystal-clear glass, the type of glazing you choose will also impact on conservatory pricing. A triple glazed conservatory will cost around 33% - 50% more than a double glazed conservatory. There are also other types of glazing worth considering. Costing up to 20% - 40% more than standard double glazing, these include:

  • Low-e conservatory glass
  • Self-cleaning conservatory glass
  • Noise control conservatory glass
  • Decorative conservatory glass, e.g. stained glass or etched glass
  • Toughened conservatory glass
  • Laminated conservatory glass

Property access

Issues surrounding access to the property can also affect conservatory prices. For example, if the ground conditions are poor or the land is located on a slope. Drainage also needs to be accounted for, as conservatory budgets may need to be stretched to address issues such as relocating underground drains.
