How to become a Mystery Shopper

If there's one thing better than getting paid hard cash, it's getting paid hard cash to shop or eat at your favourite haunts. Sound too good to be true? Mystery Shopper JobsWorking as a mystery shopper or mystery diner is a super flexible part-time opportunity for students. Not only do you get paid for your time and get to choose the hours you work, but you also scoop up freebies in the process.

Most of the big retailers are signed up to some kind of mystery shopping scheme, so there's plenty of work out there. However, with around 500,000 people registered as mystery shoppers in the UK alone, competition to land a job is getting increasingly tougher.

So is it really worth it? We've done the research and put together this comprehensive guide to ensure you're armed with all the info you need.

What is mystery shopping?

mystery-shopperWhile the clue is in the name, mystery shopping isn't about getting your Poirot on down the local Primark, but it's not far off.

Mystery shopping is a job (yes, it really is a form of employment) where you sign up to an agency or independent company that pays 'mystery shoppers' to visit businesses anonymously around the country in order to check that specific standards are being met (e.g. cleanliness, good customer service, etc.).

It isn't just about clothes or groceries either. You could find yourself grabbing a free dinner at a restaurant, having your eyesight tested or even counting trains at a train station – so mystery shopping is also mystery dining, mystery drinking, and…err… mystery train counting?

How does mystery shopping work?

The process involved in mystery shopping tends to vary from job to job, but most commonly you'll be given a specific set of instructions to read before venturing into a shop or business.

These instructions will normally include the following:

  • Guidelines on what to buy as part of the assessment (this part is normally quite flexible)
  • list of questions to ask in store
  • Details of things watch out for and remember to take a mental note of (e.g. cleanliness, lighting, if you were greeted as you walked in, etc).

Once you get home, you'll usually need to write up a report on your findings and send this to the agency. This can take anything up to two hours to complete, so make sure you leave yourself enough time afterwards to get the paperwork done.

Other forms of mystery shopping jobs

  • Postal monitoring: You sign up to have brochures and catalogues sent to your home address and record how long they take to arrive, what state they arrive in, etc.
  • Mystery shopping by phone: This one can even mean starting work before getting out of bed! Telephone mystery shopping involves calling up stores with general questions and assessing (and recording!) how these are answered.
  • Email mystery shopping: Similar to phone mystery shopping, but this method is obviously more for online stores or stores who have a strong online presence.
  • Online survey: This can entail completing product reviews or simply filling out online surveys related to certain brands.

How much will I earn?

savings in a jarThe pay for mystery shopping tends to vary dramatically, but unfortunately in recent years companies have started offering less money, or in some cases no payment at all.

In the past, some full-time mystery shoppers have reported earning between £30-40,000 per year, but it's worth knowing that this is after spending many years on the job and earning a reputation in the industry. Unfortunately, it seems the days of this sort of mystery shopper salary are over.

Today, you're more likely to be offered work where you won't receive payment, but will be given a budget to spend in store, and will be allowed to keep what you buy as a freebie (so make sure you choose something you really want!).

Most companies also offer travel expenses, so make sure you keep hold of any train tickets you use so you can claim the cash back.

Best mystery shopping companies

Caesar voting with his thumbThere are a whole slog of companies offering mystery shopper work in the UK, but unfortunately this also means the industry is rife with fake companies trying to scam you into paying registration fees to join agencies that don't exist.

It should always be free to sign up to mystery shopping, so if a site asks for payment, approach with extreme caution.

When in doubt, check out the MSPA website (Mystery Shopping Providers Association) to see if the company is listed. If their name's not down, run a mile!

Signing up is generally pretty pain free: there's no need for CVs or references – just fill out an online survey and you're all set.

Here's our take on some of the most popular mystery shopper sites in the UK.

  1. Market Force

    market force mystery shopper jobsFormerly known as Retail Eyes, this is one of the UK's most well-known mystery shopping sites and with 300,000 registered members, it's certainly one of the biggest.

    They host a massive range of jobs – with everything from visiting opticians to checking out local pubs – so chances are you'll be able to find something up your street.

    They also recently launched a mystery shopping app that allows you to locate and pick up jobs in your current location – handy to make a quick buck when you're already out shopping somewhere.

    Payment: Very low or just reimbursement for items you buy in store (worth £5-15)

    Pros: Variety of assignments

    Cons: Bad customer service.

  2. Field Agent

    Field Agent mystery shoppingField Agent is an app that offers a list of mystery shopping tasks according to your location.

    Field Agent is most well-suited to young people, as it's quick, easy and caters to the idea of being on the go a lot.

    Tasks can vary from taking a quick sneaky pic of a shop display, to submitting feedback on customer service. Payment is processed through PayPal, making it pretty quick and straight forward, too.

    Payment: £2-8 per task

    Pros: Easy to use, wide variety of tasks available and payment is simple

    Cons: Payment is low, so you'd have to do a few tasks to make some pocket money.

  3. The Mystery Dining Company

    Mystery dining jobsLove eating out but hate having to fork out for it?

    The Mystery Dining Company offer free meals at certain restaurants to those culinary experts (or near enough!) who are willing to take the time to write a detailed report on their experience afterwards.

    To join up you need to first ‘pass’ an application process to see if you’re the right fit. Rejection rates are quite high, so make sure you take the time to do this part properly.

    Also worth noting that the more you work and the better job you make of it, you'll be awarded with a reviewer rating badge – go for gold and you could be awarded with a Michelin star experience!

    Payment: No payment offered, but meal is paid for and sometimes travel expenses covered

    Pros: Free meals!

    Cons: Reporting process takes longer than mystery shopping as requires more detail.

  4. GfK

    Gfk mystery shopperAnother reputable company, there are a wealth of assignments on GfK covering the whole of the UK and often smaller UK suburbs as well as bigger cities.

    You won't find yourself caught up with lengthy applications here either. All you need to do is complete a survey on their website to sign up and you're good to go.

    However, one complaint would be that the reporting process for GfK is notoriously time-consuming. In this sense, you're expected to really work for your cash, but GfK do pay generously!

    Payment: Generous (but undisclosed)

    Pros: Generous payment

    Cons: Reporting process is time-consuming.

  5.  GBW (previously Gap Buster)

    Gapbuster mystery shoppingGAPBuster have recently rebranded themselves as GBW (we're still not sure why, or what GBW stands for). McDonald’s is their biggest client so this company is a great choice if you fancy some free happy meals!

    They have been reported to send out repeat assignments to the same location as well to monitor improvements, so this might not be the best choice if you're looking for variety.

    Payment: Between £5-10 per job

    Pros: Paperwork is clear and easy to complete

    Cons: Payment is quite low and reimbursement slow.

  6. Retail Maxim

    Retail mystery shopping jobsRetail Maxim is a popular agency with a lot of subscribers, but we have heard complaints that this has resulted in jobs being scooped up a matter of minutes after they are posted online!

    This means you'll have to be quick in order to bag yourself a job, and also be quite flexible with your time.

    They do send out cheques to cover shopping trips in advance, which is good for those of us who can't afford to wait for reimbursement later.

    Payment:  £7-12 per job + travel expenses

    Pros: Money for spending in store offered upfront

    Cons:  Jobs are few and far between.

  7. Grassroots

    Grassroots mystery shopperGrassroots are the company to go for if you’re not interested in being bombarded with emails advertising available positions.

    The best way to find work with Grassroots is to keep checking their website, as it’s constantly updated throughout each day.

    Video options are also available which tends to pay more, and payment is normally received around 3-4 weeks after the job.

    Payment: £5-10 per job + freebies

    Pros: Clear instructions and quick payment

    Cons: Jobs normally only available in the bigger UK cities.

  8. Tern

    Mystery shopping with TernTern Consultancy is a nice option if you’re looking to try out some of the different varieties of mystery shopping, as they also offer opportunities for video and audio-only shopping (which also tend to pay a bit more).

    However, ironically for a company assessing customer service, we've heard that theirs is not all that great!

    Payment: Around £12 per job

    Pros: Payment is the highest we’ve seen

    Cons: Bad customer service.

Mystery shopping do's and don'ts

Find a mystery shopper job


  • Work regularly: While you can choose your hours, the secret to getting the best jobs is being flexible and offering to work regularly. The more you work, the more your reputation will grow, and the work will start a-rollin' in.
  • Memory practice: As you won't be able to have a notepad handy on the job as this will give the game away, you'll need to perfect your memory so you can remember details for your report later. Think of it as good practice for exam time!
  • Keep the tax man happy: It's unlikely you'll earn enough to be taxed, but mystery shopping technically does count as self employment, so if you do think you might earn over the tax bracket, make sure you declare it. Check out our students tax facts page to see if this applies to you.
  • Sign up to multiple companies at once: There are loads of mystery shopper sites out there, but work can be scarce, so signing up to multiple companies simultaneously will increase your chances of finding something that's a good deal for you.
  • Keep receipts: Anything you buy as part of a mystery shopping effort, make sure you always hang on to any receipts in case a company asks to see them.

  • Be late: You'll have to submit a report after each visit, and this normally has to be done within a specific time frame. If you hand your report in late, you might not be paid and could be axed from further jobs.
  • Ever pay to register: No reputable mystery shopper business will ask you to pay to join. However, they probably will ask for your bank and sort code, but this will be in order to pay you for your work.
  • Forget to ask for details: As we covered – there is a lot of variation involved in the kinds of reimbursements and payments with this kind of work. Make sure you know exactly what you're signing yourself up to for before taking on a job.
  • Rely on Mystery Shopping as a source of income: Whilst this is an fun way to make some extra cash, it's not a reliable form of income. Some companies will even take up to two weeks just to reimburse you for money spent as part of a job, so this is not a good idea if you're on a particularly tight budget.

So whilst you're not likely to be able to pay off your student loan with your earnings, mystery shopping is fun to get involved in, and it's also something interesting to put on your CV if you do it regularly.

If you're looking for a bit of fun and freebies, give mystery shopping a whirl!
