Last updated: October 2026 · Jobs, pay and app features change often, and what’s available depends on where you live, so check each company’s own site before you sign up.
Supermarket mystery shopping UK jobs let you get paid for checking stores you probably walk past every week. You visit a supermarket, follow a short brief, note what you see and send a report, and the company pays you a fee (plus a refund for anything you were asked to buy).
It won’t replace a salary, and nobody can promise you a set amount. But if you like noticing details and you’re already out and about, it can be a handy little side hustle. In this guide I’ll walk you through how it works, which companies are genuine, how to get your first jobs, how to spot scams and what to know about tax.

How supermarket mystery shopping UK jobs work
Supermarkets and the brands they stock want to know what really happens in their stores. Are the shelves full? Is the new promotion on display? Was the checkout queue short? Did a member of staff help when you asked? Instead of guessing, they pay research companies to send ordinary shoppers in to look.
There are two main types of job:
- Mystery shops: you act like a normal customer and report on the experience, such as how you were greeted, how clean the store was, or how a staff member answered a question.
- Retail audits and store checks: these are more direct. You might check whether a product is in stock, photograph a display, or note the shelf price of an item. Some are quick tasks done through an app.
Either way, the pattern is the same: you accept a job, read the brief, visit the store, then submit your answers, photos and receipt. Once the company approves your report, you get paid.
Genuine companies to try
These companies all have their own UK-facing sign-up pages, and each says on its site that joining is free (or does not ask for a joining fee). Jobs depend on your area and on which campaigns are running, so it’s worth joining a few.
iShopFor Ipsos
Ipsos, the big research company, recruits mystery shoppers in the UK through its iShopFor Ipsos site. It says registration is always free, and that you need to be 18 or over, have a smartphone and internet access, and hold a UK bank account. You choose jobs in your area and see the fee and any reimbursement before you accept. Jobs are managed in the iShopFor Ipsos NEXT app, where you can upload photos and submit surveys.
Market Force
Market Force is one of the long-established names in mystery shopping and has a European arm. It says it’s free to sign up and that it has been a member of the Mystery Shopping Providers Association (MSPA) for more than a decade. Shops are scheduled and reported through its Eyes On Global app, where you fill in your report and add photos. UK-based Retail Eyes became part of Market Force back in 2011.

Roamler
Roamler is an app-based platform with a UK office in Birmingham and UK support for its “Roamlers”. Its retail tasks include product and service checks, mystery shopping and merchandising in places such as supermarkets and petrol stations. You apply online, then pick tasks that are available near you.
Shepper
Shepper runs an on-demand app for mystery shops, in-store checks and quick audits for UK brands. You pick jobs from a map, arrive at the location, answer questions and take photos in the app. Its FAQ says it’s free to sign up, and once a job is approved your pay goes into a Shepper wallet that you can withdraw to your bank.
Check any other company with the MSPA
There are other mystery shopping agencies in the UK. Before you join one you haven’t heard of, look it up in the MSPA Europe/Africa member search, which you can filter by country. The MSPA says its members can’t charge shoppers for access to work.
How much does supermarket mystery shopping pay?
Honestly, it varies a lot. Most jobs pay a small fee for the visit and report. If the brief asks you to buy something, that purchase is usually refunded up to a set limit, on top of the fee. The company tells you the fee and the reimbursement before you accept, so you always know what you’re signing up for.
A few things to keep in mind:
- A refund isn’t profit. If you’re reimbursed for a basket of shopping, you’ve only got back what you spent. Your actual earnings are the fee.
- Pay usually comes after approval. The MSPA says shoppers are typically paid after their visits are approved, often monthly. App platforms may pay faster, so check each one’s terms.
- Work out your real hourly rate. Add up the time in store, the time writing the report, travel and parking. A job that looks fine on paper can be poor value if you make a special trip.
The jobs that tend to make the most sense are the ones in stores you already visit, or on a route you’re already taking.
How to sign up: step by step
- Pick two or three genuine companies from the list above, or check others in the MSPA directory.
- Register on the company’s own website or official app. Type the address in yourself rather than clicking a link in an email.
- Fill in your profile carefully. Add your postcode, how far you’re happy to travel, and when you’re free. This decides which jobs you’re offered.
- Complete any short test or training. Some companies ask you to read guidelines or answer a few questions before your first job.
- Turn on notifications. Popular jobs can go quickly, especially on app platforms.
- Accept one or two nearby jobs first so you learn how each company’s reports work.
What a supermarket mystery shopping job involves
Every brief is different, but most follow this pattern:
- Read the brief before you go. It tells you the date or time window, what to check, what (if anything) to buy and which photos are allowed.
- Visit at the right time. Some jobs must be done on a certain day or within set hours. Visiting outside the window can mean your report is rejected.
- Be discreet. For a mystery shop, act like any other customer. Make a mental note of names, times and details, and jot them down once you’ve left.
- Take only the photos you’re asked for. If staff ask you to stop, stop politely and follow their instructions.
- Keep your receipt. You’ll usually need to upload a clear photo of it to get the purchase refunded. Keep the paper copy until you’ve been paid.
- Submit your report promptly. Most companies want it the same day or within a set deadline. Be accurate and specific, and never make up an answer if something was missing.
Tips to get more jobs
- Join a few companies. No single company has work everywhere, all the time.
- Be reliable. Turning up in the time window and submitting good reports on time is how you get offered more work.
- Write clear, factual reports. Short, specific answers (what you saw, when, and who said what) are exactly what clients want.
- Widen your travel radius a little if you have good transport, but only where it still makes sense once you count your costs.
- Check apps at regular times. New tasks often appear when campaigns start.
- Keep your profile up to date, including where you shop, so you’re matched with suitable jobs.
Mystery shopping scams to avoid
Sadly, mystery shopping is a favourite cover story for scammers. The MSPA’s own scam guidance is clear: genuine companies will never ask you to pay to carry out work for them, and mystery shopping companies don’t offer a salary.
Red flags
- A fee to join, buy a “starter pack” or get “certified” before you can work.
- A cheque or money arriving before you’ve done anything, with a request to pay it in and send some of it on by bank transfer, gift cards or money transfer. The cheque bounces, and the money you sent is gone.
- Being asked to move money through your bank account. This can make you a “money mule”, which is a crime even if you were tricked.
- A job offer out of the blue by email, text or social media, especially from a free email address or one that doesn’t match the company’s website.
- A big salary for easy work. If it sounds too good to be true, it probably is.
What to do if you’re unsure
- Don’t click links in the message. Go to the company’s website yourself and contact them from there.
- Check the company in the MSPA member search.
- If you think it’s a scam, report it to Report Fraud (reportfraud.police.uk) or call 0300 123 2040. Report Fraud replaced Action Fraud on 4 December 2025. In Scotland, report to Police Scotland on 101.
- If you’ve sent money or shared bank details, call your bank straight away. Citizens Advice also suggests hanging up and calling 159 if someone phones to trick you into handing over money.
Do you pay tax on mystery shopping?
Mystery shopping fees are likely to count as trading or miscellaneous income, because you’re usually paid as an independent shopper rather than an employee. It’s the fees that are your earnings. A refund for something you were told to buy simply pays you back.
The good news is the £1,000 trading allowance. It covers your total gross income (before expenses) from all your side hustles added together, not £1,000 for each app. So your mystery shopping fees are added to any other trading income you have, such as app tasks, casual jobs or selling things you’ve made.
- £1,000 or less in a tax year: you usually don’t need to tell HMRC.
- Over £1,000: you need to register for Self Assessment by 5 October after the end of the tax year (so by 5 October 2027 for the 2026/27 tax year), then fill in a tax return. You can choose to deduct the £1,000 allowance or your actual expenses.
For the full picture, read my side hustle tax and £1,000 trading allowance guide, and check your own position with HMRC.
Is supermarket mystery shopping worth it?
It can be, if you treat it as a small top-up rather than a regular income. It suits you if you’re organised, notice details and already visit supermarkets often. It’s less worthwhile if jobs near you are rare or you’d need to make special trips.
Try a handful of nearby jobs, keep a note of the fee, your time and your costs, and then decide which companies are worth sticking with.

Do I have to pay to become a mystery shopper?
No. Genuine companies don’t charge you to join or to get work. If you’re asked to pay, treat it as a likely scam.

Usually, yes, if the brief asks you to buy something and the company reimburses it. Check the brief, as the refund limit and rules vary by job.
How do I get paid?
Most companies pay by bank transfer once your report is approved. Some apps pay into an in-app wallet that you withdraw to your bank.
Do I need any experience?
No. You need to be reliable, follow instructions and write clear reports. Some companies ask you to be 18 or over and have a smartphone.
Is mystery shopping income taxable?
