How much would a small conservatory cost?

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. They have three walls that ‘lean’ against the existing wall of the building. This means they require fewer materials and labour to build. Whereas P-shape or T-shape conservatories are much larger, and therefore more expensive.

Conservatory add ons and upgrades

Conservatory add-ons and upgrades will also push up the price of your conservatory. Add ons and upgrades include dwarf walls, cornices, internal pelmets, lighting, heating, crestings, roof vents, and more.

Of course, finishing touches will significantly affect conservatory prices too. Finishing touches include coloured uPVC, woodgrain effects, powder-coated aluminium, marine-grade finished aluminium, and specialist micro-porous paints.

How to find the best conservatory prices

1.    Conservatory installer

Industry accreditations and memberships provide peace of mind that a double-glazing company is reputable. If a glazing company cuts corners on planning for your new conservatory, it could mean further unnecessary costs down the line. So, before obtaining at least 3 separate quotes, be sure to look out for the following trust signals.

  • 10-15 years 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

It is true that a FENSA certificate isn’t needed for a new conservatory. However, FENSA registered companies are regularly assessed to ensure their work complies with the latest building regulations.

Getting a range of quotes from both national and local installers will also help determine the cost of your conservatory. 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.

Don’t forget that better quality conservatory materials will last longer and are more likely to add value to the property. Therefore, your new conservatory could end up paying 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. Other types of roofs include glazed roofs and solid tiled roofs. Roofs with skylights or lanterns tend to be the most expensive option.

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 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. Conservatory budgets may need to be stretched to address issues such as relocating underground drains.
