District nurses and health visitors have been among those hit hardest and say that their mileage allowances, which have not changed significantly since 2000, no longer cover the cost of motoring.
The new rates will mean that a regular user of a car above 1500cc will receive 44p per mile, with standard users receiving 58.3p per mile.
The rates also apply to all other mileage bands in the Agenda for Change agreement. Trusts will also be duty-bound to follow the guidance as it will be written into the AfC agreement as an amendment.
Mike Jackson, Unison senior national officer, said that a new mileage allowance scheme should be in place by the end of the year pending the outcome of a review.
He said: '‘We are pleased that the employers have listened to the mounting tide of anger among NHS staff who drive their cars while working for the NHS.'
