Join Sponge Loyalty Programme for Member Discounts
Sign up to the Sponge loyalty programme to unlock exclusive member discounts, reward points and special offers on every order.
5% Off Your Entire Sponge Order
Save an extra 5% on your whole order with a Sponge voucher code. Stack with sale prices for even better value on cakes.
Up to 50% Off Selected Sponge Cakes and Treats
Sponge runs seasonal clearance lines with discounts reaching 50% on specific cake flavours and gift sets. These tend to be end-of-line or limited-edition bakes rather than the core Victoria or lemon ranges, so check the sale section regularly if you're flexible on flavour and want the deepest price cuts available.
15% Off Your First Sponge Order
New customers can take 15% off their entire first purchase, whether you're trying a single gluten-free sponge or stocking up for a birthday spread. This welcome discount applies across the full range with no minimum spend, making it the strongest single-use saving for first-time shoppers.
Member Prices Stack with Free Delivery Threshold
Loyalty programme members access reduced pricing on selected lines, and because those lower prices still count toward the £40 free-delivery threshold, you can reach free shipping while paying less per item. Sign in before adding cakes to your basket so member pricing activates automatically, then watch the delivery fee drop off at checkout. 4 verified codes and 8 deals are live on this page.
Stack Newsletter Signup with Sale Prices for Bigger Savings
Join the Sponge mailing list first to receive any subscriber-exclusive promo codes, then shop the clearance section where items are already reduced by up to 50%. Applying a newsletter code on top of already-discounted cakes compounds the saving - useful for large orders or gifting multiples. Our page currently lists 4 verified codes alongside 8 active deals for Sponge.
Up to 50% Off Selected Sponge Cakes and Bakes
Sponge runs seasonal clearance lines with discounts reaching 50% on specific cakes and gift sets. These tend to cover end-of-line flavours and limited-edition bakes rather than the core range, so check the sale section before placing a full-price order - the markdowns are applied directly to the product price.
15% Off Your First Sponge Order with Welcome Code
New customers can shave 15% off an entire first purchase, making it a good moment to try Sponge's bestsellers like the lemon drizzle or carrot cake. The welcome discount works across the full range including gluten-free options, so you can stock the freezer and still pay less than standard shelf prices.
Free UK Delivery on Orders Over £40
Sponge waives delivery fees once your basket reaches £40, which is easy to hit with a couple of their large celebration cakes or a mixed box of Victoria and chocolate traybakes. Standard UK mainland shipping applies automatically at checkout - no code needed.
Verified Sponge Vouchers - Tested Daily for Active Codes
Our team checks Sponge promo codes every day to confirm which ones actually work at checkout. Bookmark this page and check back before placing your cake order - codes expire and new ones appear regularly, so the best discount today might be different from yesterday's.
Gluten-Free Cakes at Sponge - Dietary Range Without the Premium
Sponge bakes a dedicated gluten-free line so coeliacs and the gluten-sensitive do not have to miss out on proper cake. The range includes individually portioned treats and full-size cakes, and because they are baked fresh rather than mass-produced, quality stays high. Watch for seasonal gluten-free additions around holidays.
