Widely recognised as the UK’s most accurate source of public sector spend data, Illuminator is derived from an unrivalled range of sources, including more than 128 million categorised invoices from over 1,777,000 suppliers across 1000+ public sector organisations, ranging from councils, NHS trusts and CCGs through to emergency services and government departments.
