The Rank Foundation’s Time to Shine programme funds paid opportunities at charities for people in need of full-time work, which also helps to address skills and capacity gaps at the charities themselves.
The programme was originally developed in Northern Ireland, but the £3.3m National Lottery funding will allow the charity to roll out the programme across the rest of the UK.
A spokeswoman for the Rank Foundation, which promotes leadership and enterprise development in the social sector, said the charity had put the original idea for the scheme to the NLCF in Northern Ireland in 2016 and then developed the proposal to expand the scheme alongside the NLCF.
Caroline Broadhurst, deputy chief executive at the foundation, said: "The Rank Foundation and the fund share a passion for bringing new talent and skills into the social sector, while future-proofing the role of small and medium-sized charities.
"This grant will help to scale Time to Shine across the UK with a wider reach than ever before."
Joe Ferns, UK director at the NLCF, said the organisation was delighted to be supporting the programme.
The grant will be distributed on an invite-only basis, a spokeswoman told Third Sector, adding that the organisation was still deciding which areas of the UK it would focus on.
