NHS trusts will have to obtain formal approval from NHS Improvement to employ interim managers on rates of more than £750 a day, under new rules set out by regulators.

The rules will come into force on 31 October and will apply to all NHS trusts, foundation trusts in breach of their license for financial reasons, and FTs receiving bailout support from the Department of Health.

HSJ reported earlier this month that NHS Improvement was developing a new approvals process for interim “very senior managers” as part of efforts to reduce the sector’s spending on staffing agencies.

The details have now been published on the regulator’s website.

The move follows the introduction of pay caps for nurses and doctors, as well as an approval process for management consultancy contracts and interim managers at clinical commissioning groups.

The regulator is preparing to highlight NHS providers that are falling short of their targets to slash agency spending, including plans to publish lists of the highest earning agency staff at individual trusts.

HSJ has asked NHS Improvement, the DH and NHS England if they plan to publish their own lists of high earning interims and agency staff.

The DH and NHS England did not respond. NHS Improvement said: “We are considering our own publication requirements as we develop the new policy further over the coming weeks and months.”
