Key takeaways
- A 6x8ft aluminium greenhouse is the most popular choice for UK gardens, fitting standard plots and paths
- Aluminium frames start from £399 and need almost no maintenance over a 25-year lifespan
- Wooden greenhouses like the Swallow Kingfisher offer 15-20% better heat retention but need annual treatment
- Toughened glass is safer and more durable than horticultural glass, especially in exposed gardens
- Mini greenhouses from £349 suit patios and small spaces where a full-size model won't fit
- Budget £400-£600 for a solid starter greenhouse, £800-£1,500 for mid-range, £2,000+ for premium timber
