Quick answer: You can redeem a B&Q voucher on DIY.com from inside My Basket. Under Order Summary, click “Add B&Q Club card, voucher code, or discount card” and enter your code. Note: the voucher field is inside My Basket, not on the product page and not at the payment step.
What You'll Need
- A valid B&Q voucher code
- An item added to your DIY.com basket
- Optional: a DIY.com account (not required to apply a code)
How to Apply a Voucher on DIY.com
1Add an item to your basket
Browse DIY.com and choose any product. Click Add to Basket to begin checkout.
The basket icon in the top-right corner updates instantly. If it does not change, try refreshing.
2Go to your basket
Once the item is added, click Go to Basket. This opens your order summary and shows all available checkout options.
3Enter your voucher code
Inside My Basket, scroll to the Order Summary section. Click the link labeled:
“Add B&Q Club card, voucher code, or discount card”
A small field will appear. Type or paste your voucher code, then press Apply. The link is easy to overlook because it blends into the order summary text.
Troubleshooting
My voucher code isn’t working
Common reasons include:
- The code has expired
- The code requires a minimum spend
- The code is product-specific
- The code is single-use only
- The code is for in-store use, not online
Try removing and re-adding the item, or refresh the basket page.
I can’t find the voucher box on mobile
On phones, the voucher field is collapsed by default. Scroll to Order Summary, then tap the link to reveal the input box.
Can I use more than one voucher?
DIY.com typically allows one voucher per order, but you can combine:
- A B&Q Club card
- A voucher code
- A discount card
…if the promotion terms allow it.
