It is expected this fall in the figures is due to far fewer journeys in vehicles being made during lockdown.
ABI’s figures showed that there were 324,000 new claims made in the second quarter of this year, a fall of 48% from the previous quarter.
The value of claims settled during the lockdown period also fell, but at a much slower rate than the number of new claims, with £2.1bn being paid out.
However, the value of the average claim paid jumped 27% on the previous quarter to £4,600, the largest quarter to quarter rise on record.
She added: ‘‘However, cost pressures remain, such as rising vehicle repair costs, reflecting ever more complex vehicle technology and increased vehicle theft.
“With personal injury costs also continuing to rise, it is important that the whiplash reforms scheduled to be implemented in April 2021 are not delayed further.’’
