What we do

We support the Prime Minister and Deputy Prime Minister, and ensure the effective running of government. We are also the corporate headquarters for government, in partnership with HM Treasury, and we take the lead in certain critical policy areas.

CO is a ministerial department, supported by 19 agencies and public bodies.

We work on these topics

  1. Government efficiency, transparency and accountability

    Openness and transparency can save money, strengthen people's trust in government and encourage greater public participation in decision-making. Read more

  2. Community and society

    The government is supporting people who care about their communities and want to get involved in improving them. It believes that people understand the needs of their area best, which is why it is transferring power so people can make more decisions locally and solve their own problems to create strong, attractive and thriving neighbourhoods.
