Details of the scale of the comms cutback came in an answer to a Parliamentary Question last week.
Andrew Jones MP, exchequer secretary to HM Treasury stated: "The cost for running HM Treasury Communication department, including all staff and running costs in 2016/17 was £1,950,886, a reduction of over a quarter of the 2009/10 spend."
The drop in the comms spend mirrors a wider decline in costs across government since 2010, as part of the rebalancing of the country’s finances, according to Treasury officials.
The department has one of the smallest comms teams in Whitehall, with just 20 staff working in comms, according to statistics released by the Office for National Statistics this month.
"Delivering efficiently" is one of the Treasury's objectives between now and 2020, according to its single departmental plan, published last year.
It stated: "As a department HM Treasury is committed to reducing its operating costs over the Parliament, whilst continuing to improve the efficiency and effectiveness of its services."
