The LHO is an integral part of the network of twelve public health observatories (PHOs) across the UK and Ireland that form the Association of Public Health Observatories (APHO). Further information on the APHO network and its work can be found at: www.apho.org.uk.

The map below shows the configuration of the PHOs. Each of the English regional PHOs share the same geographic boundary as the Government Office of that region.

The LHO produces information, data and intelligence on the health and health care of the 7.8 million people who live in London. We provide up-to-date information for health practitioners, policy-makers and researchers to assist with commissioning and policy decisions. LHO also runs training programmes in health intelligence training and capacity-building programmes for health practitioners.

In addition to providing intelligence for its London stakeholders, the LHO also has a national lead role on behalf of APHO on health inequalities, ethnicity and tobacco. It is the lead Observatory for NICE, the NHS Confederation and the Centre for Public Scrutiny. In its national lead roles, the LHO works closely with the Department of Health and the Information Centre for Health and Social Care as well as the Healthcare Commission.
