The Department of Health (DH) spends more on providing desktops per full-time employee than any other government department, according to new data.

The October business plan quarterly updates from 17 central government departments showed that DH spent £1,336 on desktop provision per employee in Q1 2011-2012, up from £1,329 in the previous quarter.

This is nearly three times more than the average desktop provisioning spend (£489) of all the government departments.

HM Treasury was the second highest spender (£1,000), followed by the Department of Energy and Climate Change (£696.99).

In comparison, the Department for Work and Pensions (DWP), whose desktop services are provided by HP, spent just £128 for desktops for each person, with HM Revenue and Customs (HMRC) and Department for Transport (DfT) spending £158.64 and £168.87, respectively.

However, DH was among the departments which spent the least on third-party ICT, spending £3.68 million in the first quarter.

According to the available data - the Ministry of Defence did not have a figure for its third-party ICT spend - this was significantly less than the highest spender, DWP, which spent £263 million. HMRC spent the second-highest amount, £226.54 million, followed by the Home Office with £167.9 million.

The business plan updates also showed each department's spend on their top five projects.

For example, the Cabinet Office reported the life cost of its National Cyber Security Programme at £77 million, while the Department for Education had invested £7.03 billion in Building Schools for the Future. Among the Ministry of Justice's projects, it has invested £127 million in shared services and £40 million in 'future IT sourcing'.

Meanwhile, the Home Office counted the cost of its e-Borders project at £801 million, and put the cost of its new passport programme, to deliver a new supplier and design for the UK passport, at £453 million.

DH's figures for IT projects stood out again in this area, as it recorded the cost of the North, Midlands and East (NME) Programme for IT at £5.64 billion, the London Programme for IT at £1.05 billion, the Southern Programme for IT (SPfIT) at £598 million and the cost of extending the NHS N3 Network at £383 million.

Where relevant, departments also reported the cost of identified fraud. HMRC identified by far the largest cost in this area, £3.3 billion, followed by the Department for Business, Innovation and Skills (BIS) (£4 million).
