John Healey, Chancellor of the Exchequer

Consider a community nurse in rural Lincolnshire who leaves her base at 7.40 with eleven visits ahead and a car that belongs to her. By late afternoon she will have driven close to ninety miles, claimed a mileage rate set nationally, and delivered care that no hospital bed could have provided more cheaply. Her fuel cost appears in no trust board paper. Its impact could become more pronounced if the Chancellor proceeds with a carbon charge on imported refined fuel, a measure reportedly under consideration for the Budget but not yet confirmed by the Treasury.

The proposal would apply a carbon border adjustment to imported petrol and diesel, matching the net zero costs that British refineries already carry. The industrial logic is coherent, since a domestic refining sector that pays for decarbonisation while foreign competitors do not will shrink, and the country would then import more of what it burns. Motorists fear the cost will reach the pump. No rates, start dates or revenue estimates have been published, and fuel duty remains frozen only until the end of December. Nobody outside the Treasury can say what the charge would add to a litre. The link to the NHS is therefore indirect and contingent. It is also real.

Fuel is small beside pay, which dominates provider spending, and that has encouraged a belief that movements in its price can be absorbed. That assumption belongs to an earlier era of the NHS. Current policy is shifting care out of hospitals through neighbourhood health services, virtual wards and community diagnostic centres, all of which rely on staff and equipment being able to travel. Ambulance fleets, patient transport contracts, pathology couriers and the logistics behind national supply chains run largely on diesel. Many community and mental health staff use their own vehicles and are reimbursed at set rates that trail pump prices.

The financial architecture leaves little room to respond. Budgets are fixed in cash terms at spending reviews, and trusts are already working to demanding efficiency targets while trying to bring waiting lists down. A fuel cost increase would not be recognised in allocations, because it sits in private contractors' price lists and thousands of individual expense claims, and no central line records it. Transport providers would pass it on at contract renewal. Rural and coastal systems, where distances are longest and public transport thinnest, would feel it first, in places where access to care is already harder to secure.

There is a second strand in the NHS's own climate commitments. The service has a target of net zero for the emissions it controls directly by 2040, and its leaders are bound by duties tied to national emissions law. A carbon price on fuel is the kind of signal that should accelerate fleet electrification. Yet electrification needs capital, and capital is the NHS's scarcest resource. A price signal without the means to respond functions as a tax.

The practical implications are specific. Trust and integrated care board leaders should ask procurement teams to model fuel exposure now, including indexation clauses in transport contracts and the generosity of staff mileage policy. The Treasury should consider pairing any such charge with Budget funding to transition ambulance and community fleets to lower-carbon alternatives, alongside a faster mechanism for reviewing reimbursement rates. Health-tech firms selling remote monitoring, route planning and virtual ward platforms will find that the economic case for avoiding journeys has strengthened. Patients in sparsely populated areas should expect that any increase in costs shows up first in the length of a wait, and only later in a published figure.

The Budget will be read for what it does to petrol prices. NHS leaders should read it for what it implies about the cost of their own strategy. Care closer to home is promoted as cheaper than care in hospital, and it may well be. That case has so far been made without pricing the road, and a government that wants care delivered in the community should know what the journey costs.
