The price of our basket of fruit and veg recorded its first rise since June following three successive falls. It is now 9.8% more expensive than it was five weeks ago and 0.4% more costly than at the same time last year.

The biggest four changes were all price rises. White seedless grapes accounted for the biggest rise, up 25.8% since September 18, but prices are still 12.6% down on the same time last year.

Onions provided the second biggest price rise, following two consecutive price falls. They are now 19% more expensive than five weeks ago, and 23.2% more expensive than at this time last year. A difficult growing season caused by a hot July and a wet August, which reduced yields by 10-15% and also hit size, is being blamed.

The price of strawberries rose 16.3% since the previous survey, following a period of stable prices. However they are now 18% cheaper than at this time last year.

Loose mushrooms rose in price after three falls, as supplies switched from the UK to Poland and the Netherlands. They are now 13.4% more expensive than five weeks ago, but 3.4% cheaper than at this time last year.

The price of pears remained unchanged since the last survey, but it is now 36.5% higher than at this time last year, compared with an 8% fall in the price of apples year on year. Oversupply last year from Southern Hemisphere sources reduced pear prices, while this year English apples are benefiting from promotional activity.
