The local infrastructure body Navca has pledged to pay its staff the living wage and is calling on its members to do the same.
The living wage is higher than the minimum wage and is a concept designed to ensure workers and their families can live free from poverty. It was launched in 2001 by the charity London Citizens, a member of Citizens UK.
Navca said it had agreed to pay its employees the current living wage rates of at least £7.20 an hour outside London and £8.30 an hour in the capital. It said it was the first national voluntary sector umbrella charity to become an accredited employer under the campaign.
Joe Irvin, chief executive of Navca, said his organisation supported the campaign because it tackled poverty, which was at the heart of what the organisation was about.
"Paying the living wage lifts families out of poverty and improves quality of life," he said. "Research also shows that it is good for the businesses that support it because it leads to improved quality of work, reduced absenteeism and improved employee recruitment and retention."
He said Navca was committed to encouraging all its members to join the campaign and to promote it among the 160,000 local charities its members support.
Rhys Moore, director of the Living Wage Foundation, said 16 third sector organisations had been given his organisation's living wage employer accreditation, including Unicef, Save the Children, Cafod and Amnesty International.
A further 20 are working towards accreditation, he said.
