How to earn money as a mystery shopper in the UK

Mystery shopping will not replace a salary. But for people who want a flexible, low-commitment way to earn small amounts regularly, it is more accessible than most expect.

Mystery shopping involves visiting a business as an ordinary customer, observing specific things, and then completing a report about what you found. The businesses using these services include retailers, restaurants, banks, hotels, petrol stations, and car dealerships. They pay mystery shopping companies to carry out the visits, and those companies pay individual shoppers to do the work.

It is genuine, it is legal, and the earnings are real. But it is not a high-income opportunity, and it requires some care to avoid the many scams that operate in the same space.

What the work actually involves

A typical assignment might ask you to visit a coffee shop, order a specific item, time how long you wait, note the cleanliness, assess whether staff offered a loyalty card, and complete a detailed written report within a few hours of leaving. Some assignments require a purchase that is reimbursed in addition to a small fee. Others pay a flat fee with no purchase required. The reports need to be accurate and submitted promptly.

Pay varies by assignment. A brief retail visit might pay £5 to £10. A restaurant visit with a meal reimbursed might pay £15 to £25 plus food costs. More complex assignments or those requiring specialist knowledge pay more. It is not possible to do large volumes of work in a short time because the available assignments depend on what clients need in your area.

Legitimate companies to register with

Reputable UK mystery shopping companies include Retail Eyes, GFK Mystery Shopping, Ipsos Mystery Shopping, Market Force, and Tern. Registering with several gives you access to more available assignments. Registration is free. Any company that asks you to pay to register or to purchase a starter kit is a scam.

The mystery shopper cheque scam

This is one of the more persistent financial scams in the UK. You receive an unsolicited email or letter offering mystery shopping work, along with a cheque for a large amount. The instructions tell you to cash the cheque, keep a portion as payment, and wire the rest somewhere as part of a payment transfer assignment. The cheque bounces after you have sent the money. Legitimate mystery shopping companies never send unsolicited cheques. If it arrived without you registering, it is a scam.

Tax on mystery shopping income

Mystery shopping income is taxable above the £1,000 trading allowance. If you earn more than that in a tax year from mystery shopping and similar casual work, you need to declare it on a self-assessment return. Reimbursements for purchases made as part of an assignment are generally not income, but the fees paid for completing the assignment are.
