The private equity backer of Burger King UK has injected millions of pounds of new funding as part of a deal which paves the way for their partnership to be extended into the 2040s.

Sky News understands that Bridgepoint has invested a further £15m into the fast food giant in recent days, with a further sum – thought to be up to £20m – to be deployed over the next 18 months.

The new funding has been committed as Burger King UK’s Master Franchise Agreement with a subsidiary of Restaurant Brands International has been extended to 2044 in a deal which is said to align the interests of its various financial stakeholders more closely.

Burger King’s British operations comprise roughly 575 outlets, and employ approximately 12,000 people.

In results released this week, Burger King UK said it had delivered a “solid performance…amid sector headwinds” in 2024.

Revenue increased by 7% to £408.3m, with underlying earnings before interest, tax, depreciation and amortisation up 12% to £26m.

The company also said it had completed a refinancing process, with the maturity of its bank facilities pushed out to March 2028.
