‘Our 2025-26 Budget provides record funding of £21bn for health and social care - with NHS boards receiving an additional £200m to reduce waiting lists and help support reduction of delayed discharge. Significant additional activity is now underway following this investment.
‘We have already made good progress through our targeted funding approach. NHS boards have exceeded the commitment to deliver 64,000 appointments and procedures in 2024-25, funded through our £30m investment, with boards reporting delivery of 105,500 appointments and procedures.'
