Public borrowing for the financial year ending March 2025 is now estimated to be £1bn lower, with the current financial year so far (April-August) £2bn lower.
The ONS stated that monthly borrowing estimates were out by between £200m and £500m since January.
This revision comes as the Chancellor prepares for a challenging Budget in November, where she needs to find significant savings and faces pressure over potential tax increases and the two-child benefit limit.
