Best Greenhouses UK (2022): How to Choose & The Best Brands
Tuesday, 14 December 2021 | Matt
If you're a true gardener, you know that a greenhouse is essential for sowing seeds, taking cuttings, and taking care of your young plants in harsh winter weather.
Whether you want to grow your own vegetables like tomatoes, or plant a beautiful collection of pansies, you'll need a good greenhouses kit to get started.
Here in the United Kingdom, there is a wide range of different brands you could choose from, as well as a diverse selection of types and sizes.
So in this article, we'll talk you through how to choose the best greenhouse for gardening in 2022, as well as some options for each type or brand.

Greenhouse Location - Choose the Size & Shape
Where you want your greenhouse to be located will likely control what size and shape of greenhouse you will choose.
If you have lots of space to work with, then it's not so much of a problem, but if you're working with a tight space, you need to choose a type that's appropriate.
You can usually find a size of greenhouse to fit any space, which means it tends to come down to the shape of the greenhouse.
You want your plants to receive the most amount of sun possible, so your greenhouse should be located in a sunny spot in the garden.
If you have a south facing garden, you'll have a greater range of sunny spots than a north facing garden.
This is particularly important in the winter, where there is a much shorter amount of daylight.
There are also other things to consider when choosing your greenhouse location:
Next we'll talk about the most popular greenhouse shapes:
Shape 1: Freestanding Greenhouse
When you think of a greenhouse, you will likely be thinking of a freestanding greenhouse.
It will be a square or a rectangle depending on the length, and has a door at the front, with space inside for a potting bench and shelving.
It's definitely the most popular type of greenhouse, as it provides even space to work with.
Shape 2: Lean to Greenhouse
A lean to greenhouse looks like half a freestanding greenhouse leant up against a wall.
It only has 3 sides, and is designed for when you have a narrow space to work with, such as down the side of a house.
Shape 3: Cold Frame
A cold frame is a mini greenhouse designed for a small space on a patio or balcony area.
They tend to be square or rectangular, and offer a small place to keep young plants protected from cold weather.
They are often the cheapest type of greenhouse.
Shape 4: T-Shaped
T-Shaped greenhouses are particularly useful when you want a large rectangular greenhouse but prefer the look or convenience of a central double door.
While less popular, they are very convenient in the right circumstances, and look rather nice.
While rarer, some brands have started to manufacture hexagonal and octagonal greenhouses, which are particularly appealing for slabbed areas at the centre of a garden that match those shapes.
The main issue with these shapes is that you'll likely be restricted to a smaller variation in sizes, meaning you may not get the size appropriate for your space, or have to settle with a compromise.
There are also low-height eave shaped greenhouses, where the pitch of the roof is much less extreme, designed for when you have restricted height.
Greenhouse Sizing & Measurements
The main thing to consider about the greenhouse size is to make sure it's slightly smaller than the location you've chosen to place it.
So fully measure your space, and choose a greenhouse that gives you some access around the sides.
This is both better for general cleaning and maintenance, as well as looking better than a squished in greenhouse.
Greenhouses tend to go up in two-foot increments (eg 4', 6', etc.) so choose the width that's closest to your space size (leaving some extra room as stated above).
Greenhouse Styles & Materials
Now you've decided on the location, size, and shape of your greenhouse, it's time to choose the style and material.
There are two types of materials available, which I'll explain below:
Material 1: Aluminium
Aluminium greenhouses are the most common, and they have a lot of benefits:
They are usually available in some colour finishes, but tend not to have as many colour options as wooden greenhouses.
Material 2: Wooden
Wooden greenhouses are very popular for a number of reasons:
The main downside to wooden greenhouses is that they cost more than aluminium.
Are greenhouses weatherproof?
Yes greenhouses are designed to be left outside in all weather conditions, and so they're specifically treated to ensure they're weatherproof.
Aluminium as a material cannot rust, and all wooden greenhouses use treated wood to ensure they don't rot.
You will usually get the option to choose the type of glazing panels in your greenhouse.
Not all greenhouses are made from glass, there are three options to choose from:
You may wish to add accessories to your greenhouse to make your growing tasks easier.
Some of the more popular accessories include:
Other Greenhouse Styles
If you don't want to opt for a traditional greenhouse style, then you have a few options to choose from:
Style 1: Dwarf Wall Greenhouses
Dwarf wall greenhouses have a small wall running around the bottom half of the greenhouse, with a traditional aluminium top half.
They stop the greenhouse from looking overly dominant, which is often beneficial when you're choosing a particularly large greenhouse size.
They are also much more sturdy, as only half of the greenhouse is made from lightweight aluminium.
Style 2: Victorian Greenhouses
Victorian greenhouses are characterised by large glazing panels, small uprights, and tall eaves.
They look stunning, and they're also available in dwarf wall options.
Style 3: Potting Sheds
A potting shed is a combination greenhouse, where it has half of one side as a traditional wooden shed, and the other half as a glazed greenhouse.
These are ideal for those who want the best of both structures with one purchase, or have limited space where they have to choose between the two.
