About Our Aluminium Greenhouses
Aluminium-framed greenhouses are the low-maintenance choice for British gardens. The frame will not rot, warp, or need annual treatment like timber. A powder-coated finish resists rust and holds its colour for decades. We stock 860 in-stock aluminium models, with prices from £219 for a compact lean-to up to large professional structures.
The slim aluminium glazing bars let in more light than thick wooden frames. That extra light matters in our short UK winters. Colours run from plain mill-finish silver through to forest green, anthracite grey, and black. Choosing your frame is only half the job. Our wooden greenhouses suit gardeners who want a traditional look, while our plastic greenhouses work for tight budgets and balconies. Most aluminium models take horticultural glass, toughened safety glass, or twin-wall polycarbonate.
Why We Chose This Range
"We have fitted aluminium frames since 2012, and they handle British weather better than any other material. The trick most people miss is the base. An aluminium frame has no give, so a base that is even 5mm out of square will jam the door and crack a glass pane. Get the base flat and dead square first. After that, the frame goes up clean and stays put for 20 years."
— Matt, Founder of Greenhouse Stores💡 Tip: Pick toughened safety glass if your garden is open or exposed. The heavy, rigid panes resist wind far better than lightweight polycarbonate, which can flex and pop out in a gale.
🔧 Matt's Installation Tip: Anchor the base properly
Never spike the ground anchors into soft soil. Concrete them in, or bolt the frame to a paved or concrete perimeter. A storm will lift an unanchored aluminium greenhouse clean off the ground. We have seen it happen. Spend your effort on the foundation and the rest is straightforward.
Matt's Pick: Vitavia 8x6 Venus 5000 Greenhouse - Toughened Glass
Best For: First-time and family growers who want a durable, well-priced 8x6 with safe glazing.
Why I Recommend It: It is our most-fitted aluminium model. The toughened glass is safe near children, and the size suits the average garden. Easy to build over a weekend.
Price: from £629

Frequently asked questions
Does an aluminium greenhouse need painting or treating?
No. Aluminium frames need no painting or treatment. The metal resists corrosion on its own, and powder-coated frames hold their colour for years. A wash with soapy water once a year keeps the glass clear.
Will an aluminium frame rust?
No, aluminium does not rust. It forms a natural oxide layer that protects the metal. This makes it a sound choice for coastal gardens where salt air corrodes steel and rots timber.
Which glazing suits an aluminium greenhouse best?
Toughened safety glass suits most gardens. It is rigid, safe near children, and stands up to strong wind. Polycarbonate insulates better but flexes in exposed spots, so pick it only for sheltered sites.
How long does an aluminium greenhouse last?
A quality aluminium greenhouse lasts 20 to 30 years. Set it on a flat, square base and clean the glass now and then. Most models carry a manufacturer warranty of 5 to 25 years.
Is aluminium better than a wooden or plastic frame?
Aluminium needs the least upkeep of the three. Wood looks warmer but needs yearly treatment, and plastic frames suit only small structures. For a lasting greenhouse with little fuss, aluminium wins.
