Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, which (a) external data analysts and (b) data collection companies his Department has used in each of the last five years.

The information requested is not readily available and could be provided only at disproportionate cost.

HMT routinely records contracts let, where the total contract value is of £10,000 (excl VAT) or more on the Tender and Contract Database.

While the database does retain details of individual suppliers it does not categorise them according to their status e.g. whether they are data analysts and / or data collection companies

To ascertain the information requested would involve drilling down into the information contained and a call out to all individual suppliers to ascertain their formal status at disproportionate cost.
