What is the Bradford Factor?
The Bradford Factor is an absence scoring method used by some employers to highlight frequent short-term absence. It does not measure how ill someone is. It measures the pattern of absence by giving extra weight to the number of separate absence occasions.
In practice, this means one continuous absence usually produces a much lower score than the same number of days split across several separate absences. HR teams often use the score as a trigger for a conversation, support review, or policy checkpoint.
How to calculate it
The formula is S2 x D = B. S is the number of separate absence occasions, D is the total days absent, and B is the Bradford Factor score.
Example
3 occasions x 3 occasions x 7 days = 63
Using the score fairly
Many UK employers use score thresholds as review triggers. The exact trigger points should come from the employer's own policy and should be applied with care. Disability, pregnancy, long-term health, reasonable adjustments, and wider context may all matter.
