Internal energy prices should increase by 5% compared to April, adding £ 85 per year to household invoices, according to the Council Cornwall Insight.
The forecastist, who is widely considered for his specific forecasts, said that a household using a typical quantity of gas and electricity would pay £ 1,823 per year.
The higher prices predicted come into force at the same time as the increase in tax and council tax invoices in April.
However, minimum wage levels will also increase while state benefits and pension will increase.
Cornwall provides that the price ceiling will go from £ 1,738 per year for a typical cleaning.
The prices of gas and electricity that should increase, some houses could examine the options available to repair their energy rate.
Ofgem, the regulator, will announce the official level of the energy price ceiling on February 25, which will affect the houses in England, in Wales and Scotland.
The price ceiling affects 26 million households on the default variable prices and is set every three months by OFGEM. Although the cost of each gas and electricity unit is capped, the total bill is not.
The regulator illustrates the ceiling by showing the impact on the annual bill of a household with typical energy consumption.
In January, there was an increase of 1.2% – which worked as an additional £ 1.75 per month compared to the previous ceiling.
A high price period means that households have collectively built a debt of 3.8 billion pounds sterling to suppliers.
The average household in the arrears owes more than £ 1,500 for electricity and £ 1,300 for gas.
