How to Make Money Fast UK: 12 Legit Ways to Earn Cash Today or This Week

Why "fast" means different things

Before diving into the list, it helps to be honest about timelines. "Today" usually means cash in hand or a near-instant transfer. "This week" means within five to seven days. "This month" covers anything that pays reliably within 30 days. Some methods on this list genuinely deliver same-day or next-day money; others take a little longer but are far more lucrative. A few are worth starting now even if the payout lands in three or four weeks.

The other variable is starting capital. Matched betting, for instance, needs a float of at least £50–£100. Selling stuff on eBay needs stuff to sell. Cashback bonuses need you to make a qualifying purchase. Keep your own situation in mind as you scan the list.

1. Cashback signup bonuses

£15–£50 in days

TopCashback and Quidco both run welcome bonuses for new members. At the time of writing, TopCashback offers around £15–£30 just for making a qualifying purchase through the portal, and Quidco has similar deals. If you were already planning to buy something, whether it is a takeaway, a broadband contract or a new pair of trainers, doing it through a cashback portal costs you nothing extra and puts real money back in your pocket within a few days of the purchase being tracked. Withdrawals to your bank account typically clear within two to five working days once a deal has been confirmed.

You can stack both platforms because they are separate accounts. See our TopCashback vs Quidco comparison for a breakdown of which pays more across different categories.

This suits anyone with a qualifying purchase already on their shopping list. Zero skill required and almost zero time investment.

2. Paid surveys

£1–£5/hr

Paid surveys are not going to replace your income, but they are genuinely fast to start. Prolific is the pick of the bunch for hourly rate (studies often pay £6–£9 per hour and the platform enforces a minimum), while Swagbucks and YouGov are easier to qualify for and pay out to PayPal or gift cards relatively quickly. Most platforms pay within a few days of reaching their minimum withdrawal threshold.

Realistic expectations: you might earn £10–£40 in a week if you are consistent and have a profile that qualifies for plenty of studies. It is background-noise money rather than fast cash in the traditional sense, but it requires no skills, no equipment and no startup cost. Check out our guide to the best UK paid survey sites for a fuller ranking.

Best suited to people who have spare time in the evenings or on commutes and want something genuinely passive to run alongside other methods.

3. Matched betting

£200–£500+ in week one

Matched betting is the highest legitimate hourly return on this list for someone with a bit of float capital and a few hours to learn the basics. It works by using free bets from bookmaker welcome offers to cover both outcomes of a sporting event, locking in a near-guaranteed profit regardless of the result. It is not gambling in the traditional sense because you are hedging every bet.

The catch is that it takes three to five hours to fully understand how it works before you place your first bet, and you need a starting float of at least £50–£100 to cycle through the welcome offers comfortably. Once you are up and running, beginners commonly make £200–£500 from welcome offers alone in the first week. Read our full matched betting guide for beginners before you start, especially the parts on keeping records for HMRC.

Suited to people who are detail-oriented, comfortable using spreadsheets or a matched betting platform like OddsMonkey, and have the float available. Not suitable if you have any history of problem gambling.

4. Selling unused stuff

£20–£300+ this week

A clear-out is one of the most underused fast-cash methods. Vinted, eBay and Facebook Marketplace all have different payout timings. Facebook Marketplace pays on collection, so it is the fastest for bulky items. Vinted releases funds to your balance after the buyer confirms receipt (usually two to three days after delivery), then you withdraw to your bank in one to three days. eBay holds funds for new sellers for up to 21 days, which is frustrating, but that window shortens significantly after a few positive transactions.

Clothes, small electronics, kids' toys, books and sporting equipment consistently sell quickly. For more detail on clothing resale specifically, see our guide on making money on Vinted. A good clear-out across all three platforms realistically brings in £50–£300 in a week depending on what you have lying around.

This suits almost everyone, especially families with outgrown children's items or anyone who has not decluttered recently.

5. Food delivery driving

£8–£14/hr after costs

Uber Eats, Deliveroo and Just Eat all allow you to apply online and, once onboarded, most drivers are out earning within two to three days. You need a bike, scooter or car, a valid licence, and to pass a basic background check. Pay varies significantly by area and time of day, but peak hours (Friday and Saturday evenings, lunchtime on weekdays) can bring in £12–£14 per hour gross. After fuel and wear-and-tear, the net figure is more like £8–£12 per hour.

Weekly pay is standard on most platforms, though Uber Eats offers instant cashout for a small fee. Our full breakdown of Uber Eats and Deliveroo in the UK covers the platforms in more detail, including which pays the most in different UK cities.

Suited to people who already have a vehicle, live in or near a town or city, and can commit to at least a few peak-time shifts per week.

6. TaskRabbit and AirTasker gig work

£12–£25/hr

TaskRabbit and AirTasker connect people with local workers for one-off jobs: furniture assembly, handyman tasks, moving help, cleaning, delivery driving in a van and more. Setting up a profile is free and takes under an hour. How quickly your first job comes in depends on your location and the tasks you offer; popular cities like London, Manchester and Birmingham tend to have a steady stream of bookings. Some new Taskers get their first job within 24 to 48 hours of going live.

Rates are set by you, and skilled tasks like plumbing or electrical work obviously command more. General tasks like flat-pack assembly or garden clearance typically bring in £15–£20 per hour. Payment is released after the job is marked complete, usually clearing your bank within one to three days.

Best for people with a practical skill, a car, or simply spare time and physical energy. Suited to those who want to earn quickly without being tied to a rota.

7. Freelance gigs on Fiverr or PeoplePerHour

£0 in week one, £50–£300/week by month two

Freelancing is on this list with a caveat: your first sale on Fiverr or PeoplePerHour rarely comes this week. Building a profile, getting your first review, and being found in search takes time, often two to four weeks for the very first job. That said, if you have a marketable skill (copywriting, graphic design, video editing, social media management, translation), setting up your profile today means you could be earning within the month.

PeoplePerHour lets you bid on posted jobs, which can speed things up if you write compelling proposals. Fiverr is more passive but scales better once you have reviews. Withdrawals on Fiverr go via PayPal or bank transfer 14 days after an order is marked complete; PeoplePerHour releases funds faster after mutual sign-off.

Suited to people with a digital skill who are willing to invest a week or two in setup before money starts arriving.

8. User testing

£5–£10 per 20-minute test

Sites like UserTesting and TestingTime pay you to try out websites and apps and give spoken or written feedback. Each test typically takes 15 to 25 minutes and pays £5–£12. The catch is that you need to pass a sample test first and then wait to be matched with studies that fit your demographic. Once accepted, tests do not arrive every day, but a few per week is realistic if you have an average consumer profile.

Payments on UserTesting go to PayPal seven days after a test is approved. It is not enough to live on, but it is genuinely easy money for very little effort once your account is active.

Suits anyone comfortable speaking aloud on a screen recording and willing to wait a few days for the initial approval process.

9. Bank switching incentives

£150–£200 in 4–8 weeks

This one belongs in the "this month" category rather than today or this week, but it earns its place because it is about as close to guaranteed free money as you can get. Banks including First Direct, NatWest, Santander and others regularly offer £150–£200 to switch your current account using the Current Account Switch Service (CASS). The switch typically takes seven working days to complete, and the cash lands within a few days of meeting the qualifying criteria (usually setting up two direct debits and paying in a minimum monthly amount).

You can switch multiple times per year if you move between different eligible banks. The money is paid as cash, not vouchers. Check MoneySavingExpert for the current live deals as they rotate frequently.

Suits almost anyone with a UK current account, a couple of existing direct debits, and some patience for the four to eight week window.

10. Plasma donation and clinical trials

£20–£40 per donation; £50–£200+ for trials

The NHS does not pay for blood donation, but approved plasma donation centres (such as those run by BPL Plasma) offer reimbursement of around £20–£35 per session to cover time and travel. Legitimate clinical trials pay more, ranging from around £50 for a simple outpatient study to several hundred pounds for longer residential trials. These are run by universities and regulated research companies, and your safety is always the priority.

Be cautious: always check that any trial is registered on the ISRCTN registry or the MHRA's clinical trials database before signing up. Avoid anything that asks you to pay to join or promises returns that seem disproportionate.

Suited to healthy adults with flexible schedules. Not suitable for everyone depending on medical history.

11. Mystery shopping

£5–£15 per assignment

Mystery shopping involves visiting a shop, restaurant or service and completing a report on your experience. Legitimate agencies used by UK brands include Ipsos Mystery Shopping, Market Force and Grass Roots. Payment per assignment ranges from £5 to £20, plus any reimbursement for purchases you had to make as part of the visit. Payments usually arrive within 30 days of submitting your report.

It is not a fast earner in volume terms, but if you combine a mystery shop with a trip you were already making (a supermarket run, a coffee stop) then the hourly return is decent for very little extra effort. The key is registering with multiple agencies to maximise available jobs in your area.

Suits people who are detail-oriented and can write clear, concise notes. A car helps if you want to access assignments outside your immediate area.

12. Selling a service locally

£20–£100+ this week

This could be lawn mowing, car washing, dog walking, tutoring, ironing or handmade goods at a local market. Posting in your local Facebook group or Nextdoor community is free and can generate bookings within hours. Payment is in cash at the time of service, making this one of the genuinely fastest ways to earn money today if you have a useful skill and live somewhere with demand.

The earning ceiling is modest unless you build up a regular client base, but for a single week's fast cash, offering a local service to neighbours or on community boards is hard to beat for simplicity.

Suits anyone with a practical skill, a bit of equipment (even just a lawnmower or a lead for dog walking) and willingness to knock on a few virtual doors.

What to avoid

For every legitimate option above, there are at least ten scams dressed up as opportunities. Avoid anything that promises daily returns on crypto "investments", requires you to recruit other members to earn (classic pyramid or MLM structure), charges you a joining fee to access survey panels, or guarantees earnings without any effort on your part. In the UK, if something is promoted heavily on Instagram by accounts with no history and claims you can earn £500 a week doing nothing, it is almost certainly a scam. Stick to platforms you can verify, check Trustpilot reviews, and never hand over your bank details to receive a payment.

How to pick the right method for your situation

Speed is only one factor. Here is a simple way to match your situation to the right method.

If you need money today: local services (lawn mowing, car washing, dog walking for cash), Facebook Marketplace items collected in person, or matched betting if you already understand it and have the float.

If you can wait three to seven days: food delivery onboarding, selling on Vinted, cashback signup bonuses, TaskRabbit, user testing.

If a month is acceptable: bank switching (highest guaranteed return for lowest effort), freelancing, mystery shopping, plasma donation.

Stacking methods is where the real gains come from. A realistic week might look like: £30 from a cashback signup bonus, £50–£80 from a few evenings of food delivery, £40 from selling clothes on Vinted, and £15 from a handful of Prolific surveys. That is £135–£165 in a single week without quitting anything or making any wild promises to yourself.
