More scam emails relating to HMRC.
They are getting more convincing, so you must give them greater scrutiny.
This one requests repayment of granted funds.
The easiest way to spot it is by checking the FULL return email address ( not just the name).
Most emails I have from HMRC end with @advice.hmrc.gov.uk
While it is possible to fake even this, the current scam emails that I have received are from an address ending in @hmrc.uk.com
Additionally read the detail in the message. Is it something you have actually applied for?
