The NHS will get an above-inflation cash boost of £3.8 billion for next year after chief executive Simon Stevens convinced chancellor George Osborne of the need for immediate funding.

Stevens had argued that the health service needed part of the government’s promised £8 billion funding rise upfront to improve efficiency as it struggles to meet demand.

“This settlement is a clear and highly welcome acceptance of our argument for front-loaded NHS investment,” he said. “It will help stabilise current pressures on hospitals, GPs, and mental health services.”

NHS trusts are expected to record a deficit of £2.2 billion this financial year.

Health Secretary Jeremy Hunt added: “This upfront investment means we can implement the NHS's own ambitious plan to transform services for the future.

"We are passionate about building an NHS that offers the safest, highest quality care anywhere in the world – with services smoothly operating seven days a week. This new money will help us finish the job.”

Meanwhile Dr Maureen Baker, chair of the Royal College of GPs, said: “It is particularly significant that ministers have decided to front-load the new investment, as was urgently requested by Mr Stevens – and we hope the injection of new resources will mean that the Five Year Forward View can quickly now become a reality.

“Only through major new investment can we cut waiting times to see a GP, recruit and retain sufficient numbers of family doctors, and give doctors enough time to deliver the high quality patient care that they want to provide in the community.”

The full details are expected to be revealed with the government’s Spending Review review on Wednesday.
