Kisharon and Langdon are exploring ways to pool resources amid fears about a potential funding gap in the next 15 years.

The learning disability charities have launched a study into their services, facilities, staff training and head office functions. It will be conducted by independent consultants and the findings are expected to be released next year.

A major report released a year ago by the two charities and Norwood found that current levels of residential care are “unlikely to be sustainable” and that an extra £30 million would need to be found by 2035.

Kisharon and Langdon are the focus of the new study due to their similar sizes and areas of common activity. But both say they will continue to explore ways to collaborate further with Norwood.

Langdon CEO Neil Taylor said the benchmark for success in the discussions between the three organisations was identifying “how we can better meet the needs of young people and adults with learning disability and autistic spectrum orders”.

His Kisharon counterpart Richard Franklin said last year’s report had “identified the issues and now we’re looking to work through the solutions.

“We’re also mindful that people have the right to choose.”

Mr Taylor also pointed out that the need to pool resources preceded the pandemic. “The argument was always very strong and that’s the reason [the earlier report] was done.”

In a statement, Norwood CEO Dr Beverly Jacobson said that “in these challenging times, the spirit of co-operation has never been more important for our community.

“We will continue to ensure vital services are available when and where they are most needed to support vulnerable people at every stage of their life’s journey.”
