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? 

how to become a mystery shopper

Working 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?

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
  • Any photographs you’re required to take
  • 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)
  • When you should have your report submitted by.

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

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 or only a few quid, 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!).

Keep a close eye on what they require you to buy, often the brief will say you can return the item you’ve bought the same day or later on, but for mystery dining jobs if the total reimbursement doesn’t cover what they’re asking you to spend, it may not be worth it. We’ve seen jobs where £15 was offered for a meal for two at a popular pizza chain, which won’t cover it, especially as you’re not usually supposed to use vouchers on mystery shops.

However, the more difficult a company finds it to get someone to complete a job, the bigger the fee will grow. We’ve found that jobs in city centres get snapped up pretty quickly, and rates stay low, but if you’re out in the sticks, doing mystery shopping can be quite lucrative. For example, we’ve done the same job in the same shop in central London and been paid £5, and when we completed it in a smaller town we received £15 plus travel reimbursement at 50p a mile.

And yes, some companies will offer travel expenses, and it’s usually based purely on distance, but if you ask nicely you could get extra money back for parking or train tickets.

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. However, some of the biggest names on this list require you to do a spelling and grammar test, you get a few tries to fill it out correctly, so don’t worry too much.

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. Mystery Dining by HGEM

    Love eating out but hate having to fork out for it?

    MysteryDining.co.uk 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, for most jobs but usually you get a big enough budget to pay for your entire meal and sometimes travel expenses covered

    Pros: Free meals!

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

  3. Serve Legal

    Are you 18 or 19 and looking for a chance to earn a bit of extra money (and get some free drinks out of it?)

    You should probably sign up to Serve Legal, they’re a test purchasing company that are essentially trying to find out if young looking people are being ID’d when they should be. Serve Legal employ mystery shoppers to go into all sorts of shops, bars and pubs to try and buy different age restricted products. Because they mainly employ people in a small age bracket they’re always looking for new shoppers to sign up.

    Apparently it’s a huge help if you have your own transport, as some of the locations you’ll need to shop at can be spread far and wide.

    Payment: You get around £7 per visit and how much of that is profit depends on what you choose to buy

    Pros: Free drinks, and they reimburse you for travel

    Cons: You only have 2 years to get involved in it.

  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.

  9. International Service Check

    If you love fashion, this mystery shopping company should go to the top of your list. International Service Check has some of the biggest names on the high street as clients, and their jobs often include trying on outfits and asking for help finding specific items. The base pay for every job is £12, which is a good starting point, but as jobs are often for a specific type of shopper – i.e. 25-35 year old males who wear certain sizes of clothing – the rates can go up significantly.

    You’ll be emailed and invited to apply for most jobs if you fit the description they look for, so keep an eye on that inbox!

    Payment: At least £12 a visit

    Pros: The money is good

    Cons: The website is very basic, and jobs can be quite complex.

  10. ESA Retail

    This is a smaller company and the types of jobs are quite diverse, we’ve completed tasks where we had to record ourselves in a bank meeting and another where we asked to try on designer jewellery. It’s worth having a look, because some of the fees can be as high as £40 a visit.

    Payment: Totally depends, but often £10+

    Pros: Very quick customer service, it’s easy to get in touch if you have a question

    Cons: It’s really difficult to sort jobs by location on the site.

  11. Assosia

    Another less well known mystery shopping company, but the jobs are a little bit different to normal. Jobs usually involve talking to members of staff and making yourself known as a mystery shopper (not much of a mystery then!). The website is almost totally blank, but don’t be alarmed, you’ll be invited to take part in jobs via email.

    Payment: Largely £10+

    Pros: The jobs are interesting.

    Cons: The website.

Mystery shopping do’s and don’ts

things to avoidCredit: Markheybo – Flickr.com


  • 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!
