Bank Holidays Cut Weekly Death Registrations, ONS Figures Show

The Office for National Statistics has warned that bank holidays typically reduce death registrations by around 10 per cent in the affected week, with a compensating rise the week after — making short-term comparisons unreliable.

Just 9,776 deaths were registered in England and Wales in the week ending 2 January 2026, the figures show — 24.6 per cent lower than the ONS modelled expectation for that week, a gap of 3,187 registrations. The ONS attributed the shortfall directly to bank holidays falling within that period, not to any real change in underlying mortality.

The ONS publishes its weekly deaths bulletin 11 days after the end of each reference week, and the counts are based on the date of registration rather than the date of death. That distinction matters. When registry offices close for bank holidays, deaths that occurred in that week simply can’t be processed — and they pile into the following week instead, creating an artificial “bounce” in the subsequent figures.

A 10 per cent drop. That’s the typical reduction in death registrations during any week containing a bank holiday, according to ONS methodological analysis. Consecutive holidays — over Christmas, New Year, or Easter — produce the sharpest effects.

For Kent, the pattern is the same. Local registration offices in the county feed data into the national ONS series, including monthly figures broken down by Medway and the NHS Kent and Medway Integrated Care Board area. In bank holiday weeks, those offices have fewer working days to process paperwork, which can push registrations into the following week and create apparent dips or spikes that don’t reflect real changes in how many people are dying.

To account for this, ONS builds bank holiday patterns directly into its expected deaths model, allowing analysts to separate calendar effects from genuine mortality signals. But the ONS has cautioned that direct week-on-week comparisons remain limited during holiday periods, and routinely adds warnings to its bulletins when bank holidays fall within a reference week.

For bereaved families in Kent, the practical side is straightforward — death registration around bank holidays may take longer, which can affect funeral timings and the processing of estates. For public health analysts and NHS Kent and Medway planners monitoring winter pressures or health crises, the ONS guidance is clear: look at several weeks together, or use the adjusted expected deaths figures, rather than treating a single week’s count as a reliable snapshot.
