The Department for International Development (DFID) and the Stabilisation Unit (SU) have outsourced some of their emergency response and operations capability since the early 1990s. The current Humanitarian and Emergency Operations Support Service (HEOSS) contract is due to end on 31.10.2017. The replacement Humanitarian Emergency Response, Operations and Stabilisation Programme (HEROS) will commence full service delivery after a period of transition. HEROS being a new contract which will allow the UK Government to increase its humanitarian response capability therefore some or all of the services may transition between HEOSS and HEROS, together with the addition of new services. DFID and the SU, as the joint beneficiaries of this contract, are now seeking to appoint a service provider to deliver HEROS. There are three overarching objectives of this programme: 1. Humanitarian emergency response management for rapid onset response, protracted crises, chronic emergencies and humanitarian reform (DFID only) 2. Operational capability and deployments (DFID and SU) 3. Procurement, logistics and infrastructure expertise and operational capability (DFID and SU).
