Phased Return to Work Pay After Sickness: How It's Calculated in 2026/27

What a Phased Return Actually Means for Pay

A phased return to work lets an employee coming back from long-term sickness build up their hours gradually — say, starting at 50% of contracted hours in week one, rising to 100% by week four or five — rather than returning to a full workload immediately. It's widely recommended by occupational health professionals and GPs via fit notes, but the pay mechanics behind it are less well understood than the concept itself.

The default approach most UK employers use is straightforward in principle, if easy to get wrong in practice: pay ordinary salary, pro-rated, for the hours genuinely worked, and treat the remaining contracted hours as continuing sickness absence — paid according to whatever sick pay entitlement remains, whether that's an enhanced occupational scheme, Statutory Sick Pay, or nothing once both are exhausted.

Worked Example 1: Occupational Sick Pay Still Available

Fatima earns £36,400 a year (£700/week gross, £140/day for a 5-day week) and returns to work after long-term sickness on a phased basis: 3 days worked, 2 days still counted as sickness absence, for the first two weeks. Her employer still has occupational sick pay remaining in her allowance, paying full salary for sick days.

For the 3 worked days, she's paid normally: 3 × £140 = £420. For the 2 sick days, because occupational sick pay is still available and pays full rate, she also receives 2 × £140 = £280. Her total weekly pay during this phase is £700 — the same as her normal full salary, because her occupational scheme happens to pay sickness absence at full rate. This is a best-case scenario that depends entirely on her employer's specific policy.

Worked Example 2: Statutory Sick Pay Only, Mid-Phase

Now suppose Daniel, earning £41,600 a year (£800/week gross, £160/day for a 5-day week), has used up his occupational sick pay entitlement before starting his phased return. He works 2 days a week for the first two weeks, with the remaining 3 days still treated as sickness, paid at the statutory rate only.

For the 2 worked days: 2 × £160 = £320 (taxed normally). For the 3 sick days, he's entitled to SSP, which is calculated per qualifying day rather than as a simple daily fraction, but broadly works out to roughly £24.65/day across a standard 5 qualifying-day week (£123.25 ÷ 5). Three sick days at that rate come to approximately £73.95. His total weekly pay during this phase is roughly £393.95 — a substantial £406.05 short of his normal £800/week salary, illustrating why the transition from occupational sick pay to SSP-only during a phased return can be a serious financial shock.

Worked Example 3: A Full Phased Return Schedule

Consider Grace, earning £30,000 a year (£576.92/week gross), on a 4-week phased return with occupational sick pay exhausted, working an increasing proportion of her contracted hours each week.

Over the whole 4-week phase, Grace's total pay is roughly £1,763.28, compared with £2,307.68 if she'd been paid full salary throughout — a gap of over £500 that many employees don't anticipate when they agree to a phased return schedule without checking the payroll approach first.

Does a Phased Return Use Up Your SSP Entitlement?

Yes — and this catches many people out. Any day within a phased return where you're not working your full contracted hours, and the shortfall is being met by SSP, still counts as a "day of incapacity" for SSP purposes. That means it reduces your remaining balance within the overall 28-week maximum SSP entitlement, exactly as a full sick day would. If your illness recurs later in the same tax year, you may find you have fewer weeks of SSP left than expected because the phased return period already drew on that entitlement.

Practical Steps Before Agreeing a Phased Return

Before signing off on a phased return schedule, ask HR or payroll exactly which pay structure applies to your unworked hours — don't assume full pay continues. Check how much occupational sick pay entitlement you have left, and how many weeks of your 28-week SSP allowance remain, since both affect the numbers directly. If there's a meaningful pay gap during the phased period, it's worth checking whether your budget can absorb it, using

to see the real net effect of a reduced-hours, blended-pay week rather than relying on a rough estimate.

Bottom Line

A phased return to work is good for recovery, but it rarely means full pay by default. Most employers pay for hours actually worked and treat the rest as sickness absence — paid at whatever occupational or statutory sick pay entitlement remains. Confirm the exact structure in writing before you start, because the difference between a full-pay phased return and an SSP-blended one can run into hundreds of pounds a week.
