A tiny, unexpected charge on your bank account — £0.01, £1.00, or another small amount — can be worrying. But small charges are usually one of a handful of common, legitimate causes. Here's what they typically mean.
When you enter your card details on a new website or app, the merchant may place a temporary small charge (£1 or $1) to verify the card is valid and active. This is returned within a few days and may not even fully settle.
Streaming services, gig economy apps, and SaaS tools commonly do a £1 card verification when you add your payment method.
Some services start a free trial with a £0 authorisation and then charge a first small payment (or the full subscription amount) when the trial ends. If you see a charge you don't recognise from a free trial period, check your email for the trial start date.
Pay-per-use services like cloud computing (AWS, Google Cloud) or prepaid mobile plans charge in small increments as you use the service. These can accumulate into many small charges per month.
Some bank accounts charge monthly maintenance fees, overdraft fees, or currency conversion fees that may appear as small separate charges. Check your account's fee schedule if you see recurring small charges from your own bank.
When you pay a merchant in a foreign currency, your bank may add a foreign transaction fee (typically 1–3% of the transaction amount). This often appears as a separate small charge on your statement.
Not necessarily — it could be a card verification charge. Search the descriptor on Detect My Charge and check if you recently added your card details to a new service.
This is almost always a card authorisation check. The merchant verifies your card is valid before charging the full amount. It should disappear within 3–7 days.
Two identical small charges could indicate a double verification, but could also be fraud. Check your email and account activity, then contact your bank if you can't identify the source.
Banks charge for various services including monthly account fees, overseas transactions, ATM withdrawals, and overdraft usage. Check your account terms or call your bank to clarify.
Yes — this is called "carding". Fraudsters place a tiny test charge to see if the card is active before attempting larger purchases. If you don't recognise a small charge, check all your recent activity carefully.
