Requests for DVLA keeper data are dominated by a handful of large operators. Together the busiest five account for the bulk of activity, at a scale of roughly 39,375 requests every day.

at £2.50 per record
What this measures: DVLA fee income at £2.50 per record, not profit. These are requests for registered vehicle-keeper records, not driver records; the registered keeper is not necessarily the person who was driving.
Two details matter for reading this fairly. The £35.9 million is fee income the DVLA received at £2.50 per record, not profit for anyone. And the data links a vehicle to its registered keeper, who is not necessarily the driver at the time.
The ranking of the five companies is accurate; the daily rate simply spreads the annual totals across the year.
