As a new academic year begins providers say national insurance rises and food price inflation has forced up prices

Parents across England are facing higher prices for school lunches as the new school year begins, with caterers blaming the government’s national insurance increase alongside rising food and energy costs.

Lunch providers say increases in staffing costs, including employer national insurance contributions announced by the chancellor last year, have added “significant extra pressure” to their budgets.

Food price inflation is also driving costs higher, pushing consumer prices above forecasts this summer. Prices for food and non-alcoholic drinks rose 4.9% in the year to July and are now 37% higher than five years ago, according to data from the Office for National Statistics.

Letters sent to parents informing them of price rises acknowledged the strain on families but said changes were unavoidable if catering services were to remain viable.
