When it comes to investing in a greenhouse, affordability can come at the expense of quality. ‘Cheap greenhouses’ may appeal to budget-conscious gardeners, but will they work for you?
This blog will define what cheap means, compare it with pricier greenhouses, and more.
What Are ‘Cheap’ Greenhouses?
Cheap greenhouses are basically the budget options. They keep costs down by using less material, being smaller, and having fewer features. That simple design is what makes them easy on the wallet.
There might be fewer extras, like shelves, ventilation, or reinforced doors, but that’s not to say they can’t work. For a small garden or a beginner gardener, a cheap greenhouse can still do the job. Just know what you’re getting: it’s practical, but it comes with limits.

There are still great deals on the market, and you’re lucky if you find them. One great example is the BillyOh Rosette Hobby in 6x4ft. It’s made from an aluminium frame with full-length polycarbonate and costs under £300.
This budget greenhouse comes with a built-in roof vent and a space-saving sliding door. It doesn’t include floor bearers, though, but it’s still a solid choice if you’re just starting out.
Why Are Greenhouses So Expensive?
Some greenhouses cost more, and a lot of it comes down to materials, such as:
- stronger frames
- thicker glass or polycarbonate
- bigger sizes
Take the frame, for instance. You’ll find powder-coated steel models, which take galvanised steel a step further. The coating protects against rust, looks cleaner, and can last longer. Though again, it comes with a higher price tag, it’s worthwhile.

You’re likely to come across pressure-treated wooden frames. The treatment protects the wood from rot and decay, making it strong and long-lasting. Even with minimal upkeep, it can perform well for 20 years or more, but it still benefits from some TLC.
Then there are the panels that make up the entire greenhouse. Thicker glass or polycarbonate, for one, does more than look solid. Both help keep heat in, protect plants from sudden cold snaps, and reduce condensation. That extra quality adds to the cost, but it makes gardening more convenient.
Size also plays a big role in the price. Bigger greenhouses need more frames, panels, and supports to handle the larger structure. Every additional metre adds to the cost of materials and sometimes installation.
Cheap vs Expensive Greenhouse
Greenhouses cost more because you’re investing in stronger materials and higher-quality construction. That doesn’t mean cheap greenhouses are a downgrade. As mentioned, they use less material, are usually smaller, and have fewer features. Their simple design keeps costs down, and prices go up when you start looking at bigger models or extras.
A cheap greenhouse might require more maintenance in the long run, such as replacement parts or frequent timber treatment.
Budget Greenhouse Alternative: Polytunnels

A polytunnel is made from a steel frame and a polyethene cover. Despite its plain design, it has a similar warming effect to glass and traps heat inside. Not to mention, it can be much cheaper, costing between £40 and £150, depending on the size.
Polytunnels can be closed off or left open at both ends. They’re common in allotments and on farms, where they are intended to be temporary structures. While low-cost, the caveat is that they can be unattractive. And due to the material used, it’s prone to damage from punctures.
Fortunately, there are greenhouses that far surpass their quality without breaking the bank. Check out our range of greenhouses for sale for options. You’ll find one that fits your budget here without compromising on quality.
