Jersey inflation accelerates, but pressures vary
Statistics Jersey’s September 2026 retail prices release showed household services contributing 0.53 percentage points to annual inflation, followed by alcoholic drinks at 0.49 points and food at 0.37 points.
Those contributions describe what made up September’s 3.0% annual rate, rather than what caused it to rise from June. Alcoholic drinks, housing, and fares and other travel were the largest upward contributors to that acceleration, partly offset by motoring, household services and leisure services.
Food prices rose 3.5% over the year, the same annual pace as in June and 0.5 percentage points above headline inflation. Within food, eggs rose 10.9%, lamb 10.6% and fresh fish 8.6%, while bacon and bread prices fell.

Sharp fuel increases come with a collection cutoff
Heating oil and other fuels increased by 47.7% over the year, while petrol and oil rose 22.7%. Statistics Jersey said geopolitical developments in the Middle East affected global energy markets and contributed to movements in heating oil and petrol prices.
The figures reflect prices collected between September 4 and September 18, 2026. Further fuel price increases, particularly for diesel, were observed after that period and are therefore absent from September’s index.
The timing matters for households comparing the release with current bills: the published inflation rate measures the collection period, not every price change occurring before publication.
Housing weight differs from its inflation contribution
Housing carries the largest weight in Jersey’s RPI basket, but it was not the largest contributor to September’s annual inflation rate. Housing costs rose just 0.2%, adding 0.05 percentage points to the headline figure.
The housing group includes rents, mortgage interest, parish rates, maintenance and repairs. Rising rents and falling mortgage interest costs pulled in opposite directions, helping explain why the overall housing increase was modest.
Jersey’s headline rate was 0.6 percentage points below the UK’s 3.6% CPIH rate, which includes owner-occupiers’ housing costs. Statistics Jersey describes CPIH as the broadly comparable UK headline measure, rather than an identical index.
Conclusion
The next Jersey inflation release is scheduled for January 29, 2027. It will provide the next official update following a September collection period that excluded subsequently observed fuel price increases.
