In February, government borrowing was at its highest level since records began in 1993, according to energy support schemes for households.
The Office for National Statistics ONS said last month that the Borrowing was 16.7 bn, the difference between spending and tax income.
This is due to spending on energy schemes this year, according to the ONS.
In February, the interest paid on government debt was 6.9 bn -- 1.3 bn less than a year earlier.
The government was supporting households with the rising cost of living, so borrowing was still high, Chancellor Jeremy Hunt said.
The government announced last week that it would extend support for energy bills at current levels until July.
The average household energy bills in Britain had been due to rise to 3,000 a year from April.
Average bills will be kept at 2,500 until the end of June, when they are expected to drop to around 2,200 a year due to falling wholesale gas prices.
The government's 400 winter fuel payment will not be renewed, meaning households' costs will still rise in the short term.
The government was spending about 1,500 per household to pay just under half of the people's energy bills this winter, according to Hunt.
