Long-Term Sick Leave Holiday Carryover Calculator

Based on the default pattern below, a typical entitlement is 20 days. Adjust the inputs for your exact figure.

5 days

Your entitlement

20 days

How it's worked out

(5 days ÷ 5 full-time days) × 4 protected weeks × 5 days = 20 days

Audit note

This is the Reg 13 protected carryover for specific circumstances — long-term sickness, maternity, parental, shared parental or carer's leave — not a general right to carry over your core 4 weeks. It must be pro-rated for part-time and part-year patterns, and used within 18 months of the end of the leave year it accrued in.

Stop tracking this by hand

Carryover only stays accurate if the balance behind it is accurate. Tempry tracks every day of accrued, taken and carried-over leave automatically, so nobody has to work out a carryover cap or a forfeiture deadline by hand again.

How this calculation works

Long-term sick, maternity, parental, shared parental or carer's leave stopped you taking your holiday? UK law protects your core 4 weeks — carry it forward, pro-rated to your working pattern, instead of losing it.

Worked example

(5 days ÷ 5 full-time days) × 4 protected weeks × 5 days = 20 days

Frequently asked questions

How much holiday can I carry over if I'm on long-term sick leave?
Up to 4 weeks (Regulation 13) of your statutory annual leave is protected and carries into the next leave year, pro-rated to your working pattern — a full-time 5-day worker carries up to 20 days, a 3-day-a-week worker up to 12.
Does my holiday keep building up while I'm off sick?
Yes. Statutory annual leave continues to accrue during sickness absence — being off long-term doesn't pause or reduce your entitlement.
Is there a time limit on using it?
Yes — carried-over leave from long-term sickness must be used within 18 months of the end of the leave year in which it accrued, not 18 months from when you fell ill.
Is this different for other protected reasons?
No — long-term sickness, maternity, parental, shared parental and carer's leave all carry exactly the same 4-week Regulation 13 cap, pro-rated to your working pattern. The reason changes your eligibility story, not the amount protected.
