The group, which operates 14 delis and restaurants across Yorkshire and Newcastle, will use the funding to roll-out across the Midlands and North of England.
Kevin Bacon, former managing director of Jamie’s Italian and Frankie & Benny’s, has joined the company as non-executive chair ahead of the expansion.
Filmore & Union was founded in 2012 by former wellness clinic owner Adele Carnell and her nephew, chef Will Pugh.
In 2015 the company crowdfunded nearly £1m towards its expansion and today has revenues of over £6m.
“Adele has created a popular restaurant concept which caters to the growing market for customers who are focused on eating well,” says BGF’s Chris Boyes.
“The team has established a good foundation to continue the rollout across the UK, and we are excited to support the next stage of growth.”
BGF has also backed other restaurant groups including Thai chain Giggling Squid and Asian group Bar Soba.
