Matt's Tip
Only one discount code can be applied per order. Pick the code that gives you the highest saving for your basket total. If your order is near a minimum spend threshold, adding a small accessory qualifies you for a bigger code.
Frequently Asked Questions
How do I use a greenhouse discount code?
Enter the code in the voucher box at checkout before paying. The discount is applied to your order total instantly. You will see the reduced price before confirming your payment.
Can I use more than one discount code per order?
No, only one discount code can be applied per order. Choose the code that gives you the highest saving based on your basket total. Codes cannot be stacked or combined with other promotional offers.
Do discount codes work on sale items?
Yes, most codes work on sale and full-price items alike. Check the individual code terms for any exclusions. Some brand-specific codes like the Janssens code may only apply to products from that manufacturer.
How often do you update your discount codes?
We update our codes seasonally and for major sales events. Spring and autumn are the busiest periods for new codes. Subscribe to our email list for early access to new voucher deals before they appear on this page.
