I pulled some data from https://www.contractsfinder.service.gov.uk/ looking in particular at any contracts put out for NHS related services. It turns out there are quite a lot, so handily enough the site allows you to download into CSV or XML format.
Once downloaded I had a root through each contract description to understand whether this is directly affecting Frontline services or whether it's something else (such as supplies, premises, management etc.)
I encourage you to play around with this interactive storyboard viz, as there's all sorts of interesting things happening.
Underneath this one is the original version I created in June 2014, but it seems the old evidence links have failed with the Government's change of website. From June 2014 to December 2014, I found it difficult to get hold of anything usable to cover the gap. If anyone is able to help on that, give me a shout!
As Promised, 2014's version (only contains Frontline services)
