The two businesses had a joint event run at the Metro Bank Edgware store in December, with local professionals and the Mayor attending.
James Bloom, Regentsmead chief executive, said: “The feedback we had from our joint evening in Edgware was overwhelming, so much so that we have agreed to join Metro Bank for another evening of talks and good conversation.
“It’s great hearing about the passion for providing customers with a high quality service from the Metro Bank team and it is something that we pride ourselves on at Regentsmead.
“There is clearly a natural synergy between our two businesses.”
He added: “By keeping this an open and informal event we hope to be speaking to plenty of people from the local community and beyond, hopefully helping with any of their finance requirements.”
The event will feature talks from Bloom as well as Metro Bank founder Vernon Hill.
Andy Veares, director of property at Metro Bank, said: “We pride ourselves on the strong relationships we have with communities, and are delighted to be hosting a second event with Regentsmesad, following a successful first event.
“We look forward to meeting many more local people, to discuss their business needs.”
The event, at 1 Southampton Row, Holborn, will start at 5pm.
