​​The Statistics Unit produces an annual report that compares prices for a range of products in the UK, Guernsey and Jersey.

The report examines the rate at which prices have changed by looking at the behaviour of the groups and sections that constitute the Retail Prices Index in each jurisdiction. Additionally, direct comparisons of prices are made where possible in order to give an indication of relative price levels.

The latest report shows that in June 2012:

• the overall increase of the RPI over the seven-year period from 2005 to 2012 has been similar in Jersey (25%), Guernsey (23%) and the UK (26%)
• during the 12 months to June 2012 the RPI increased by 3.0% in Jersey, by 3.2% in Guernsey and by 2.8% in the UK
• underlying inflation in June 2012, as measured by the annual change in RPI(Y), was similar in all three jurisdictions: 3.1% in Jersey, 3.0% in Guernsey and 2.9% in the UK
• direct food comparisons show that fresh fruit was over a third more expensive in Jersey than in the UK, fresh vegetables were almost a quarter more expensive in Jersey, and meat was, on average, around 10% higher in Jersey than in the UK
• the mean retail price of alcohol was higher in Jersey than in the UK: by 34p for a pint of beer; by 33p for a pint of lager; and by 26p for a nip of whisky
• the mean retail price of cigarettes was lower in Jersey than in the UK, by 84p for a packet of 20 cigarettes
• the mean retail price of unleaded petrol and diesel was lower in Jersey than in the UK, by around 10p per litre
• the pre-tax prices of alcohol, tobacco and motor fuels were higher in Jersey than in the UK. In June 2012, the mean pre-tax price of alcohol was about a third to two-fifths higher in Jersey (corresponding to more than 50p for a nip of whisky and around 80p per pint for beer and lager); cigarettes were more than 50% higher in Jersey (over 70p per packet); petrol and diesel were about two-fifths higher and a third higher in Jersey, respectively, (corresponding to around 20p per litre)
