The forecast from Cornwall Insight comes after Chancellor Jeremy Hunt said the energy bill help, which was originally expected to last for two years, would be cut in April.

The UK Government said the the most vulnerable families would continue to be protected from increasing energy prices.

Hunt announced the change to the energy price support as part of measures put in place to help families save money following the big hole in the public finances the Government's mini-budget left.

The Chancellor said on Monday that "it would not be responsible to continue exposing public finances to unlimited volatility in international gas prices".
