Greenhouse guides

Practical routes into choosing, positioning, equipping, growing in and maintaining a greenhouse in the UK.

Start with the decision in front of you. If you are still choosing a structure, use the greenhouse buying guides. If the order is already placed, move to bases, positioning and installation. Existing greenhouse owners can go directly to climate and equipment, maintenance and repairs or growing under cover.

Find the whole topic, not just one article

The cards below introduce the main journeys; they are not an exhaustive list of the site's guides. Each topic hub includes its narrower comparisons, checklists and problem-solving pages:

For a first purchase, read the choosing guide, mark out the footprint, then check the base and installation requirements before ordering. For an existing greenhouse, begin with the symptom or job rather than a product shortlist. Greenhouse help offers a quicker route to common problems.

The guides use UK sources and exact product specifications where a model is discussed. Conditions still vary by garden, region and structure, so manufacturer instructions and local requirements take priority where they are more specific. See how our recommendations work for our selection criteria and the details we compare.
