Fancy making a bit on the side or earning freebies? Why not become a mystery shopper?

Below you will find a list of the best UK mystery shopping companies plus tips on how to make the most of this fun and flexible side hustle. 

What Is Mystery Shopping?

Mystery shopping is a tactic employed by businesses to get unbiased feedback about their product or services. The data they collect will inform them whether standards are met and whether employees are doing their job.

Mystery shoppers pose as ordinary customers—buying products, talking to staff members, photographing items, and asking questions without being detected.

How to become a mystery shopper?

The first step is joining one of the many UK mystery shopping companies. You will be asked a few questions and probably required to complete a written or English proficiency test to assess whether you are capable of writing a final report.

You will then be tasked with going to shops or restaurants and evaluating the service while staying undercover. Typically you will need to report on the service (whether the staff approach you or provide you with up-selling offers) and the quality of the experience (the quality of food, and availability of stock—depending on what type of establishment you are visiting). 

After your visit, you will be asked to write a report. Then it’s just a matter of getting paid. 

Mystery shopping is not the only way to make extra money on the side. Here are a few more ideas:

To get started simply book a visit. After you are briefed on what you need to do, enjoy your meal, write a detailed report and get money for your expenses within 3 to 4 weeks. You can choose as many tasks as you like, but you must complete the report by noon the next day. 

Although there aren’t any payments involved, you’ll get reimbursed for any expenses on the job. Occasionally, you might be covered for travel expenses too, if there’s a need for an immediate task assessment. 

10. Streetbees: Best for Freebies 

  • Payment: £1- £10+

General stories require users to take photos of what they bought or ordered. In return, they get rewarded in the form of a voucher, an entry for a prize competition or a payment

Although Streetbees is more focused on the story aspect of the app, there are opportunities for mystery shoppers as well. The pay, however, is one of the lowest around and in most cases, you will only be able to receive vouchers and freebies instead of actual money

Mystery Shopping Tips

Here are the most common dos and don’ts when it comes to mystery shopping in the UK.

1. Sign up for more than one service 

Mystery shopping sign-ups are entirely free and open to all, so you can register with a few mystery shopping companies in the UK. This way you will have a wider selection of tasks and get engaged more frequently, which equals more money in your bank account.

2. Make sure you understand the brief

Before each task you will be given instructions on how to complete it and the amount you will be paid. Most are simple, but some might have specific instructions, so ensure you are 100% clear on what needs to be done to complete the assignment. 

Read the instructions carefully and double-check your assignment before completing it. Make sure it meets deadlines and requirements, otherwise you might not get paid. 

3. Go the extra mile 

Add extra comments where you can, they might earn you a bonus or even a position in a company. 

4. Calculate the cost before taking on an assignment

Payments from mystery shopping companies across the UK are taxable, so calculate how much profit you will be left with. It might be worth it to hold out for a better-paying job than taking on several smaller assignments. 

5. Keep receipts

If you are asked to make a purchase, hold on to the receipt as proof so you can get reimbursed later on. 

6. Act as a regular customer

To be a mystery shopper you need a keen eye for detail, a good memory and excellent writing skills. More importantly, you must be good at keeping your cool and thinking on your feet. Approach the task with confidence and act as you normally would when out shopping or dining. 

7. Secrecy is a must

Keep in mind that most companies will not pay you if you are identified by the staff as a mystery shopper. 

8. Be wary of scams

Not all mystery shopper companies in the UK are legit and you can easily become a victim of scams or identity theft. 

These are some tell-tale signs that the company is probably fake. 

  • They send you money before you complete the work and ask you to return a portion of the money since they’ve overpaid you.
  • They ask you to transfer money as part of a verification process. This is a huge red flag so avoid any company that asks you for money upfront. 
  • Your first task is evaluating a money transfer service, which requires you to send your own money to a stranger.
  • You are rewarded with a fake gift card allowing you to spend as much as you’d like in a store. 

9. Don’t be too picky

Not all jobs offered will appeal to you, but it is important to accept some smaller and possibly boring assignments for the sake of experience. Also, most UK mystery shopping companies tend to engage active users more, giving you more flexibility in choosing the next assignment. 

10. Don’t rush

Take the time to complete the report accurately. Make sure you are concise and clear—the company may not reimburse or pay you for a poorly written report. 

Bottom Line: Is Mystery Shopping Worth It in the UK?

If you’re looking for a fun and flexible job that pays a little extra money on the side, mystery shopping could be perfect for you.  On the other hand, if you need a regular job with a stable income, consider other options—you cannot make a living out of mystery shopping even if you sign up for several UK mystery shopping companies and take on multiple assignments. 

Frequently Asked Questions And Their Answers

How much do mystery shoppers make?

On average, mystery shoppers earn about £20 per job. However, in most cases, beginners usually start at around £5, whereas some agencies pay up to £150 or £200 in bonuses. These are hard to come by, though, so when doing calculations stay in the £5 to £20 range.

Do you need any equipment for mystery shopping?

In general no, but most companies will require that you own a smartphone. Most mystery shopping companies allow you to do everything in-app—from selecting the assignment to taking photos, videos or audio and writing the final report.

You could also take notes on your phone—using pen and paper might be a bit of a giveaway. Remember that staff cannot suspect you are a mystery shopper.
