I run Torchbox, a small, private tech agency in the UK. We were commissioned by NHS Digital (the state sector organisation behind these tools) to support two related projects: moving NHS.uk to https://github.com/wagtail/wagtail and setting up https://beta.nhs.uk/service-manual/ on Wagtail.
NHS Digital's procurement processes are tight and focused. They have an expert in-house team of developers and delivery managers, and they only used us on where we could accelerate the project.
As a business owner, I would have liked a bigger contract. As a tax-payer and frequent user of the NHS, I'm very happy with their efficiency.
