Staying ratio-compliant this winter: a nursery manager's guide to sickness cover
TL;DR: Winter sickness puts real pressure on nursery staffing ratios, especially now the EYFS framework assesses ratios across a whole setting rather than room by room. Here's how to build a cover plan before the season peaks.

Winter is when nursery staffing ratios come under the most pressure. Colds, norovirus and the usual seasonal illnesses mean more staff off at once, and under the updated EYFS framework, ratios are now assessed across your whole setting rather than room by room. Which changes how a single absence can ripple through your day. Here's how to plan cover before winter sickness hits, not after.
Why nursery staffing ratios feel tighter under the new framework
Since September 2026, the EYFS statutory framework has confirmed that ratio requirements are assessed against the total number of staff available to work directly with children across your whole provision, not each room taken in isolation. The numerical ratios themselves haven't changed. It's the way compliance is judged that has shifted, and it means a bad flu week can affect the whole nursery's ratio picture, not just one room.
Building a cover plan before the season starts
The nurseries that manage winter smoothly tend to have already mapped out where cover will come from before the first wave of sickness hits: a mix of internal flexibility (staff who can move between rooms), a bank of known supply staff who already understand your setting, and a clear process for who makes the call each morning when someone rings in sick.
Where supply staff fit into ratio planning
Bringing in a familiar face for sickness cover, rather than whoever happens to be available that morning, makes a real difference to both ratio compliance and the children's day. Building a relationship with a small pool of supply staff who already know your routines. Rather than starting from scratch every time. Tends to mean cover mornings run far more smoothly.
The numbers behind winter planning
“The nurseries that manage winter well aren't lucky. They planned their cover before they needed it.”
What to check now, before winter peaks
A few practical things worth confirming this month: that your single central record is current for anyone who might cover at short notice, that your ratio calculations reflect the whole-setting approach rather than room-by-room, and that your team knows the plan for a morning with multiple absences at once.
