Trusted data from leading platforms
From US warehouse pioneer to UK grocery powerhouse
Founded in 1983 in Seattle, Costco has grown into a global retail phenomenon — operating 904 warehouses in 14 countries, with the UK representing its fifth-largest market and largest in Europe.
UK market presence
Costco operates 29 warehouses across the UK — 25 in England, 3 in Scotland, and 1 in Wales. Turnover rose 5.2% to £5.6bn in 2025, placing Costco among Britain's top 10 supermarkets by revenue. Pre‑tax profit hit £218.6m, up 15.7% year‑on‑year.
Membership-only model
Costco is not open to the general public. Membership is restricted to individuals and businesses meeting eligibility criteria — typically professionals including business owners, local government employees, and people in education, medicine, banking or the police. The UK has approximately 2 million members.
Kirkland Signature & beyond
Kirkland Signature is Costco's exclusive private label, offering premium quality across groceries, household goods, clothing and more at significantly lower prices than national brands. Costco also offers cheap petrol, free samples, and an in‑store café — iconic features that drive member loyalty.

How Costco delivers value — through membership
Membership‑only access
Costco is a members‑only warehouse club. Two main membership types: Business and Gold Star (individual). Both can be upgraded to Executive for a 2% annual reward.
Bulk buying & value
Products are sold in bulk packaging at wholesale prices. Costco's business model revolves around offering low prices and a limited selection of products, often in bulk packaging.
Online & in‑warehouse
Members can shop online at Costco.co.uk with delivery to UK mainland addresses. Grocery delivery incurs a £5.99 shipping fee per order. E‑commerce sales surged 15.6% in 2025.
Kirkland Signature
Costco's exclusive private label offers premium quality at lower prices. Kirkland Signature products span groceries, household goods, clothing, and more — a key driver of member loyalty and value.
