How we help Siemens

  • Breadth and depth
    Siemens has a network of Government affairs professionals across its businesses. The breadth and depth of our expertise and policy analysis – pharma, financial services, health, infrastructure, transport, energy, manufacturing – are a great match for the Siemens network. Siemens plays a role in addressing the world’s biggest challenges, and we play a role in connecting the bigger picture to the fine details of everything from tax policy to employment law and migration numbers. All our policy teams contribute to our work with Siemens, so the Siemens Government affairs team can tailor and direct information to where it is needed in the network.
  • An evolving partnership
    The DeHavilland-Siemens partnership is seven years into its evolution – it goes back to a different geological era of UK politics – pre-coronavirus, pre-Brexit, pre-net zero. Siemens is a complex business operating in a complex world. Over those seven years, we have constantly updated our offer to Siemens to reflect changes of priority in the business and public policy.
  • Daily updates
    Siemens value the daily updates which they make the most use of – that’s the ability to track engagement and create mailing lists, the civil service add on is very practical too and it’s always kept up to date, which is so useful. DeHavilland are meticulous at updating their data base and it shows.
  • People focused
    DeHavilland are proud of the service we provide Siemens and that our culture is people-focused rather than sales-focused. All our clients get a personalised service: all our policy staff are ready and willing to help clients to interpret events and policy development. With DeHavilland, you have the conversation – sometimes you need insight as well as information.
