Choosing Mini Greenhouses: Quick Guide

Budget considerations:

• £150–£350: Compact polycarbonate models
• £400–£650: Aluminium frames with glass panels
• £700+: Premium Vitavia lean to greenhouses with professional-grade materials

Consider alternatives: Browse our small greenhouses if you have slightly more space, or explore cold frames for ground-level seed starting and hardening off.

Frequently Asked Questions

• What size mini greenhouse do I need for a small patio?

  Most UK patios (around 8×10ft) accommodate 2×3ft or 2×4ft minis comfortably. A 2×3ft model provides 6 sq ft—enough for 12–15 small pots or 6–8 larger containers. If you can spare it, 2×4ft offers 8 sq ft, perfect for tomatoes, peppers, and year-round salad greens.

• How much do mini greenhouses cost in the UK?

  Prices start from £150 for basic polycarbonate models. Expect £400–£650 for aluminium-frame minis with glass panels and proper ventilation. Premium toughened-glass models are typically £700–£900. Professional installation adds £180–£250 depending on model complexity and location.

• Can mini greenhouses withstand UK winter weather?

  Quality minis with aluminium frames and reinforced panels handle winters well, surviving winds up to 55–60mph when properly anchored. Toughened glass performs better than polycarbonate in heavy snow—polycarbonate can crack below −10°C. Lean-to designs against south-facing walls retain 3–5°C more heat overnight than freestanding models.

• Do I need planning permission for a mini greenhouse?

  Minis under 2.5m high and 2m from property boundaries typically don’t require planning permission under UK permitted development rights. Lean-to models against your house wall usually qualify if they don’t exceed 4m in height. Always check with your local planning authority—especially in conservation areas or for listed properties.

• What’s the difference between mini greenhouses and cold frames?

  Mini greenhouses: 4–6ft vertical growing space with walk-in or lean-in access—great for tomatoes, peppers, and climbers.
  Cold frames: Low to the ground (12–18 inches high), ideal for seedlings, lettuce, and hardening off. Minis cost £150–£900 vs £80–£200 for cold frames—choose based on crop height and access needs.

• How do I maintain temperature in a mini greenhouse?

  Fit at least one automatic roof vent (£25–£40) set to open at 18–20°C to prevent overheating—south-facing minis can hit 35°C+ without ventilation. Add 40–50% shade fabric in summer. For winter, line panels with bubble wrap insulation for an extra 2–3°C. Tip: wall-mounted or lean-to designs naturally stay 3–5°C warmer thanks to house-wall heat radiation.
