Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what the average staffing complement is for a ministerial private office within their Department; what grades those staff are appointed at; what the typical remuneration and contracted working hours are for those posts; and what the staff turnover rate is.

HMT ministerial private offices hire an average 6.5 FTE per office. Staff are appointed at grades: AO, EO, HEO, SEO, G7, G6 and Deputy Director. Contracted working hours for these staff members are 37 hours per week.

Staff salaries for the appointed grades are typically between £26,200 - £117,800. Designated posts may also benefit from Private Office Allowance.

The average staff turnover over the last 3 years was between 20-30%, which can include staff on loans to HMT returning to their home departments, or individuals leaving to other government departments, including on promotion.
