A minimum of one output, unless you have exceptional circumstances.
Unlike REF 2014, the number of outputs required is calculated at the level of the submitting unit, rather than linked to an individual. Each individual returned to REF 2021 must have at least one output attributed to them, unless they have experienced circumstances that mean that they do not have an eligible output. A maximum of five outputs can be attributed to an individual. Overall, a unit has to submit outputs equal to 2.5 times the full-time equivalent (FTE) of submitted. This flexibility is often referred to as ‘decoupling’ as the output requirement is no longer fully tied to individuals, allowing UOAs to choose which outputs to submit from the pool of outputs produced by their staff.
