From 1 October 2025 any bank transfers over 800 between individuals will be blocked for 24 hours as part of new verification measures set up by banks and HMRC.
False. Banks can already freeze transactions for further verification, but HMRC confirmed these particular claims aren’t true.
Social media posts claiming that from 1 October any bank transfer between individuals over 800 will be “automatically” blocked for 24 hours are false.
Viral videos claim the supposed new measure is part of a new “monitoring system” built by banks and HMRC.
Most banks already have systems in place for verifying suspicious payments, but these particular claims about a new universal system being introduced later this year are not true.
HMRC told Full Fact: “These claims are completely false and designed to cause undue alarm and fear.”
One version of the video, viewed more than 1.5 million times on Facebook, claims that transactions will be scanned “using advanced AI” to “check the source of your money, who it’s going to and why you’re sending it”.
Another claims the new measures were part of a government announcement “relayed by the Telegraph and BBC News”. It adds “if there’s any suspicion, your bank may contact you to provide documents, such as invoices, loan agreements, or proof of sale” and says “if you don’t respond, the transfer could be cancelled and flagged to tax authorities”.
Full Fact could not find any articles published by the Telegraph or BBC about any such plans.
