The challenger bank has been awarded £120mln from Banking Competition Remedies – the independent body set up to distribute the funds.
“Securing this award from BCR allows us to accelerate our plans to revolutionise banking for SMEs,” said Metro chief executive Craig Donaldson.
“It will help us bring much-needed competition to the underserved SME hotspots in the North while investing in our digital capabilities and creating new jobs.”
Starling Bank and ClearBank were the other victors, bagging £100mln and £60mln, respectively.
Money part of RBS' bailout
“These awards seek to increase competition in the business banking market and to improve the financial products and services available to SMEs,” said BCR chairman Godfrey Cromwell.
“Following the successful launch of the Incentivised Switching Scheme by BCR last year, Pool A is the first group of grants from the Capability and Innovation Fund."
After the state-backed bank scrapped plans to sell off its Williams & Glyn business to Santander, it was forced to set aside the funds to encourage those customers to switch to other lenders.
The government hopes the extra cash will boost small banks and improve High Street competition.
Still chance for CYBG et al
So far only £280mln of the £775mln pot has been dished out and there are still three more rounds of grants, so the likes of Virgin Money owner CYBG PLC (LON:CYBG) and Monzo still have a chance to secure a slice of the cash.
Other firms known to have qualified for the scheme include TSB, the Co-Op Bank and Nationwide Building Society.
Before the first round of grants had been announced, City analysts had expected CYBG, Metro and TSB to be the frontrunners to scoop the biggest slice of the pie.
Metro shares rose 5.1% to 1,370p on Friday morning, while CYBG, one of those who missed out, dropped 5.9% to 185.7p.
