Whistles Discount Codes 50% OFF May 2026

Money saving tips

  • Sign up for the newsletter: Registering your email address on the Whistles website will trigger a welcome discount code. This provides 15% off your first online order, though it is restricted to full-priced items and usually excludes the Whistles Wedding collection.
  • Shop the permanent Sale tab: The website features an ongoing sale section where past-season stock, clearance items, and older footwear lines are discounted.
  • Wait for flat-rate promotions: Whistles participates in major retail events like Black Friday, and they frequently run mid-season promotions offering a flat 20% off everything. These site-wide sales are the best times to purchase items that are normally excluded from standard discount codes, such as leather jackets and bridal wear.
  • Bundle your purchases: If you are buying a £130 dress, standard delivery will cost £3.95. Adding a small accessory or basic t-shirt to push your basket over the £150 mark will qualify you for free shipping, providing better overall value.

Delivery and returns

Delivery options

Standard UK delivery costs £3.95 and takes between three and five working days. If your order totals £150 or more, standard delivery is free. For faster shipping, Next Day Delivery is available for £5.95, provided you place the order before the afternoon cut-off time on a weekday. The retailer also offers a free Click & Collect service to their standalone physical stores.

Returns policy

Customers have 28 days from the date of receipt to return unwanted items. Returns are free for UK shoppers. You can generate a prepaid Royal Mail label or QR code through the online returns portal to drop the parcel at a Post Office. Alternatively, online orders can be returned in person to a standalone Whistles boutique (note that department store concessions will not accept online returns). Pierced earrings cannot be returned for hygiene reasons.
