The short answer
A new greenhouse in the UK typically costs around £500–£1,500+ for the structure in the popular 8x6 size with toughened glass, with smaller models starting lower and larger or premium ones higher. Professional installation usually adds around £200–£500, and a base or foundation another £150–£800 depending on type and size. So an installed greenhouse on a prepared base commonly lands somewhere in the £850–£2,500+ range. The main drivers are the size, glazing, frame material and base — a self-assembled aluminium model on a slab base sits at the lower end, while a large wooden greenhouse professionally installed on a concrete base sits much higher.
Price depends mainly on size, frame material, glazing and whether you self-assemble or have it installed. The figures below are typical UK prices for guidance, not quotations.
Typical UK costs
- 8x6 aluminium structure~£500–£1,500+
- Professional installation~£200–£500
- Base / foundation~£150–£800
- Toughened-glass upgrade~£80–£150 (6x8)
- Installed on a base~£850–£2,500+
What drives the price
- Size: you largely pay by footprint, so an 8x10 costs more than a 6x4. The 8x6 is the most popular UK size.
- Frame material: aluminium is the lower-priced default; wooden frames cost more (see the frame page).
- Glazing: toughened glass, horticultural glass and polycarbonate sit at different price points (see the glazing page).
- Base & installation: a base and professional assembly add to the headline structure price — both are covered on their own pages.

Why the installed price varies so widely
The structure is only part of the cost. A greenhouse needs a level, solid base, and if you don't assemble it yourself you pay for installation too. Because a slab base, a concrete base and a self-build base all cost different amounts, and because aluminium and wooden frames are priced so differently, the total for a finished greenhouse spreads across a wide band. The way to compare quotes is on the same scope — same size, same frame, same glazing, and whether the base and installation are included.

Frequently asked questions
How much does a greenhouse cost in the UK?
An 8x6 aluminium greenhouse with toughened glass typically costs around £500–£1,500+ for the structure. Professional installation usually adds about £200–£500 and a base another £150–£800, so an installed greenhouse on a base commonly lands in the £850–£2,500+ range depending on size, frame and glazing.
How much does it cost to install a greenhouse?
Professional installation typically adds around £200–£500 on top of the structure, depending on size and access. Many aluminium models are designed for self-assembly, which saves that cost but takes time and care.
Why is the price range so wide?
Because greenhouses differ. Size, frame material (aluminium vs wood), glazing (glass vs polycarbonate) and the base all move the figure. A quote on a clear specification gives the accurate number for your garden.
