Costco UK membership: who can join, how to join, and is Executive worth it?

A Costco UK warehouse membership isn't open to everyone. Gold Star (£42 a year) is for people in qualifying jobs and professions, and Business (£30) is for business owners and managers. Anyone can buy an online-only membership (£42), but it doesn't get you into a warehouse or a petrol station.

From costco.co.uk's membership pages and Member Privileges & Conditions, checked 20 October 2026. Prices include VAT.

Costco UK membership prices

Every warehouse membership includes a free card for your spouse or partner. Business members can add up to 6 more cardholders at £15 + VAT each, at a warehouse. Costco says it will cancel and refund your membership fee in full at any time if you're not satisfied.

Who can join Costco UK?

You must be 18 or over. For a Gold Star membership, Costco lists current or retired employees of:

• Banking and finance, insurance, and the Post Office
• Local government, the Civil Service and the Armed Forces
• The police, and fire and rescue services
• Education, and medical and health services
• Airlines

It also accepts qualified or chartered accountants, chartered architects, surveyors and engineers, doctors, dentists, opticians, pharmacists, solicitors, barristers, magistrates and advocates, and employees of companies on Costco's pre-approved list.

Costco's online sign-up form lists a few more groups to choose from: media press card holders, the Merchant Navy, registered paralegals, council employees, qualified vets, actuaries, shipmasters and marine engineers, and members of the Chartered Institute of Marketing, the CIPD and the Chartered Institute of Building.

Is my company on the pre-approved list?

Costco doesn't publish the list. Its pre-approved businesses page has a search box instead: type your employer's name, and if it has hyphens or several words, only the first word. A match means your employer has an agreement with Costco, and current or retired staff qualify for Gold Star with the same paperwork as everyone else.

What to bring: one of an employee ID card, a payslip or pension statement, or a qualification certificate, valid or dated within the last 3 months (older paperwork is fine if you're retired), plus photo ID. Your photo is taken at the warehouse membership desk.

For a Business membership, bring one piece of business evidence dated within the last 3 months, such as a VAT registration certificate, Companies House certificate, business bank statement or card, a taxi driver licence, business insurance certificate or an invoice for business purchases, plus photo ID. Costco lists more on its Business membership page.

How to join Costco UK

There are two ways, and both end at a warehouse membership desk:

• Online: pick Gold Star or Business on costco.co.uk/membership (and Executive if you want it), fill in the application with your job type and home warehouse, and pay at checkout. Costco emails your membership number, but doesn't post the cards: you collect them at your warehouse's membership counter. Take your proof of eligibility and photo ID.
• In the warehouse: go to the membership desk with your paperwork and photo ID, pay, and have your photo taken for the card.

Registering an account on costco.co.uk isn't the same as joining: without a membership you can't order or return anything online. Once you have a card, the Costco app can show a digital membership card that works for getting in and paying at every UK warehouse, though not yet at the petrol station.

Don't qualify? The online-only membership needs no paperwork. You can shop Costco.co.uk and book Costco Travel, but you can't shop in a warehouse or buy petrol.

Is Executive worth it in the UK?

For Business members the calculator uses the £40 upgrade before VAT, because most businesses reclaim the VAT. A Gold Star member pays the full £42.

How the Executive reward works in the UK

• 2% of the price before VAT on most purchases in UK warehouses and on Costco.co.uk, by the primary and spouse or partner cardholders. Add-on cardholders don't earn it.
• Capped at £500 a year for Executive Gold Star (reached at £25,000 of purchases before VAT) and £750 for Executive Business (£37,500).
• Doesn't earn: petrol and EV charging, cigarettes and tobacco, postage stamps, precious metals, charity donations, baby milk for infants up to 6 months, the food court, and guided holidays through Costco Travel.
• When: Costco adds up purchases until 3 months before your renewal date and issues the reward about then. Later purchases count toward next year's.
• How you get it: it's loaded onto your membership card. Only the primary cardholder can spend it, in one transaction at a UK warehouse's main checkouts, within 12 months. It can't be used on Costco.co.uk, at the food court or on Costco Travel, and Costco won't replace a lost or stolen reward.
• Changed your mind? The upgrade can only be refunded at your warehouse membership desk, and any reward issued or earned is taken off the refund. Downgrade before the reward is issued and you lose it.

Common questions

Can anyone join Costco UK?

Not for the warehouse. You need a qualifying job or profession for Gold Star, or a business for Business membership. Anyone 18 or over can buy the £42 online-only membership.

How do I join Costco UK?

Buy Gold Star or Business on costco.co.uk and collect your cards at your warehouse's membership counter, or join at the counter itself. Either way, bring proof that you qualify (an employee ID card, payslip or pension statement, or a qualification certificate, dated within 3 months) and photo ID.

How do I qualify for a Costco card in the UK?

Work, or have worked, in one of Costco's listed groups (banking and finance, insurance, the Post Office, local government, the Civil Service, the Armed Forces, police, fire and rescue, education, health, airlines), hold a listed professional qualification, work for a pre-approved company, or run a business for Business membership. You must be 18 or over.

Where's the list of Costco's pre-approved businesses?

Costco doesn't publish one. Use the search box on its pre-approved businesses page to check your employer's name.

Can I get a free Costco membership in the UK?

No, there's no free membership. The closest things are Costco's Refer a Friend offer (until 29 August 2027, a member who brings a new member to the membership desk gets a £10 shopping voucher and a free Kirkland Signature hot dog and soda, and so does the new member; Costco's terms), shopping as a member's guest, and Costco's promise to refund your fee in full if you're not satisfied.

Can I join Costco online?

Yes, on costco.co.uk, but the cards aren't posted. You pick them up at your warehouse's membership counter, with your proof of eligibility and photo ID.

How much is a Costco card in the UK?

£42 a year for Gold Star, £30 for Business, £84 for Executive Gold Star and £78 for Executive Business, all including VAT.

How much do I need to spend for Executive to be worth it?

For a Gold Star member, about £2,100 a year (£175 a month) of qualifying purchases, before VAT. A Business member who reclaims VAT needs about £2,000.

Can I bring a guest to Costco UK?

Yes, up to two guests and your children, but only members can buy.

Can I use my UK card abroad?

Yes. Costco says your card works at any Costco warehouse worldwide. The Executive reward can only be spent in UK warehouses.

How do I renew?

At any warehouse, by post or on Costco.co.uk. If you set up auto-renewal, Costco charges your saved card on the 27th of the month your membership expires, with a reminder email 10 days before. Turn it off at least 2 days before to stop it.
