Interest payments on UK government debt hit a new high in August.
The Office for National Statistics said interest payments in August were the highest on record.
The government is going to borrow billions to help people with their energy bills.
There will be a mini-Budget on Friday.
Government borrowing was over $12 billion in August. August 2020 is less than August 2021, but more than before the Pandemic.
The Office for Budget Responsibility had expected it to be twice as high.

The retail prices index measure of inflation hit 12.3% in August and the interest paid on government bonds increases in line with it. The government's interest payments have gone up.
Mr Beck said he was not concerned about the high debt levels as the UK's borrowing costs were still low compared to historical records.
The government spent billions to help families and businesses deal with the energy price shock.
An emergency mini-Budget will be delivered by the new chancellor on Friday to set out how the government will fund its recently announced plans to tackle the rising cost of living.

The rise in National Insurance was brought in by Boris Johnson.
She's expected to cut corporation tax and remove a cap on bankers' bonuses.
Concerns about the future strength of the public finances have been raised by the government's plans. She said that they are likely to cause inflation.
Even though these measures could potentially support individuals and businesses under strain, any large intervention will create further challenges for managing public sector debt, with £58 billion to balance already in the financial year to August 2022.
The size of this package means that even if the Bank of England's Monetary Policy Committee meeting tomorrow results in a further interest rate hike, the impact of such a decision on restraining inflation would be limited.
