UK inflation rose to 3.5% in September from 3.1% in August, putting renewed pressure on household finances just as the government prepares its Autumn Budget. The shared picture is of a fuel-driven increase; the dispute is over what should command the greatest attention next.

The left-wing account centres on the immediate cost-of-living consequences. It says higher petrol and diesel prices were the main driver of the third consecutive monthly rise, linking the increase to disruption in regional oil production during the Middle East conflict. It also highlights the prospect of a tougher winter: Cornwall Insight is reported to expect the typical annual energy bill under the Ofgem cap to rise from £1,723 to £1,999 in January.¹

Right-wing coverage reaches the same conclusion on the source of inflation, but puts greater weight on the constraints facing policymakers. One report cites ONS chief economist Grant Fitzner saying: “Increased fuel prices were again the main driver, with the cost of diesel the highest since July 2022.”² It frames the figures as an added challenge ahead of the Budget, with economists warning that persistent price growth could narrow the government’s room for manoeuvre and increase pressure for a Bank of England rate rise.

A second right-wing report similarly focuses on the risk that an energy shock spreads beyond filling stations. Richard Carter of Quilter Cheviot warned: “The longer the conflict in the Middle East persists, the greater the risk that higher energy costs seep into other areas of the economy.”³ That account also stresses the potential effect of higher rates on mortgage holders, while noting that the pension triple lock would deliver an increase based on wage growth rather than September’s inflation figure.

All three accounts therefore identify transport and energy as the immediate drivers. Their contrast is one of priority: whether the central story is the erosion of spending power now, or the difficult fiscal and monetary decisions that could follow.
