Curvy Kate UK Discount Codes and Vouchers | September 2026

Curvy Kate launched in 2006 to fill a genuine gap in the lingerie market for fuller-busted women who wanted supportive, well-engineered bras and swimwear without compromising on style. At a time when many mainstream lingerie brands stopped their sizing well before a D cup, Curvy Kate focused specifically on fuller busts. Based in London, the brand has spent nearly two decades developing lingerie in cup sizes D through K and band sizes 28 to 44, making it one of the more size-inclusive lingerie retailers in the UK.

The main product range includes bras, briefs, swimwear, babydolls, and lingerie sets. Curvy Kate also offers a virtual bra fitting tool and sizing guide to help customers find the right fit when shopping online. The company also owns Scantilly, a sister brand offering a more fashion-forward and directional approach to fuller-bust lingerie.

Because getting the correct bra size is particularly important when shopping for lingerie online, Curvy Kate offers a generous 90-day free returns policy. This is considerably longer than the 30-day return window offered by many UK retailers. UK customers can return products using a free prepaid returns label through the brand's online Return Portal.

Curvy Kate regularly runs discount and coupon promotions. Independent UK coupon websites often report a large number of active vouchers and deals. Standard sitewide discounts generally offer around 10% to 11% off, while category-specific promotions can provide much larger savings. These have included discounts of up to 50% on selected padded bras, up to 75% on selected underwear, and up to 50% on selected swimwear two-piece styles during promotional periods.

New customers can receive 10% off their first order through Curvy Kate's Sign Up and Save newsletter offer. The discount code is typically generated shortly after entering an email address and can then be applied to the first purchase.

An 11% discount is also available to eligible students and key workers, including NHS staff, teachers, and emergency services personnel. Customers need to verify their student or employment status before receiving the discount. According to independent sources, the discount can be used across orders and may also apply to sale items, although customers should always check the current terms before purchasing.

Curvy Kate also runs seasonal promotions throughout the year. Its Mid-Season Sale can reduce selected bras to £61 or less, while additional promotions may appear around the Summer Bank Holiday and Back to School periods. The brand's Outlet section is another option for finding discounts, with reductions of up to 50% on selected D to K lingerie and swimwear. During major clearance periods, some outlet bras can start from around £10.

To use a discount code, add the desired lingerie or swimwear to your shopping bag, choose the correct size, proceed to checkout, and enter the code in the box labelled "Coupon Code or Gift Card." The ability to combine multiple discounts depends on the terms of the individual promotion, so customers should check the exclusions before trying to stack offers.

For UK customers, standard delivery is free on orders over £75. Orders below this threshold have a £3.95 delivery charge. Customers who shop regularly can also purchase Unlimited Delivery for a one-off £7.95 fee, which provides free UK standard delivery on eligible orders for 12 months.

Overall, Curvy Kate is a strong option for shoppers looking for supportive, well-designed lingerie and swimwear specifically made for fuller busts. Its D to K sizing range, 90-day free returns policy, regular promotional offers, student and key-worker discount, and Outlet section give shoppers several ways to save. For the biggest potential discount, it is worth comparing the current sitewide voucher with the student or key-worker offer, if eligible, as well as checking the Outlet section before placing an order.
