The case for investing in support for parent-carers is rarely made in P&L terms. This article does. It assembles the published figures, runs the back-of-envelope on what parent-carer attrition is actually costing a 1,000-person organisation, and sets the spend on a practical advisory benefit alongside the cost of losing a single senior performer.
What it actually costs to lose one
Oxford Economics’ widely-cited 2014 study put the cost of replacing a mid-level UK employee at £30,614 per role — recruitment, lost output during the gap, and onboarding ramp time to full productivity (Oxford Economics: Cost of Brain Drain). Inflation-adjusted to 2026, that figure sits closer to £40,000.
For senior roles, the figure is much higher. SHRM and Gallup studies consistently put replacement cost at 100–200% of annual salary for professional and managerial roles. A £75,000 senior manager leaving therefore costs the organisation £75,000–£150,000 to replace, before any knock-on costs to team morale, customer continuity, or institutional knowledge.
The shape of parent-carer attrition
Parent-carer attrition does not look like the resignation curve for the rest of the workforce. It is shaped by a few recognisable triggers:
- The diagnostic year: 6–18 months of assessments, reports, and appointments after a child receives (or is being assessed for) a SEND diagnosis. Many parent-carers move to part-time hours during this window.
- The EHCP cycle: a 20-week statutory window for the local authority to issue an Education, Health and Care Plan, often followed by months of appeals. Parent-carers typically take 4–8 days of unpaid additional work during a single EHCP cycle.
- The school-refusal collapse: when a child stops attending school (the technical term is “EBSA”, Emotionally Based School Avoidance), the parent often becomes the de-facto educator for the duration. Most parents in this position drop hours or leave employment altogether within 18 months.
- The annual-review re-eruption: once an EHCP is in place, it’s reviewed every year. A bad annual review — for example, the school recommending reduced hours — can put a parent-carer back into crisis mode for a quarter.
The carer’s cliff: 600 a day
Carers UK’s aggregate figure, drawn from ONS data, is that 600 carers leave the UK workforce every working day (Carers UK key facts). The same source estimates the economic value of unpaid care to the UK economy at £162 billion per year. Parent-carers are a substantial component of both numbers; the largest single subcategory is mothers of disabled children, and the largest single age cohort leaving the workforce is 40–54.
For an organisation, the relevant figure isn’t 600 a day across the UK; it’s the proportional pull on your own headcount. If 1 in 7 of your employees is a carer (the Carers UK estimate), a 1,000-person organisation has approximately 140 carer employees. National attrition data suggests 5–8% of your carer headcount will leave employment per year specifically because of caring responsibilities — so 7–11 leavers per year, attributable to care.
The bigger number nobody is counting
Attrition is the visible cost. Presenteeism — the cost of working while distracted, exhausted, or fundamentally not present — is several multiples larger and much harder to see in your data.
The CIPD’s long-running Health and Wellbeing at Work surveys put the cost of presenteeism at 2–3 times the cost of absence (CIPD research). For a parent-carer holding it together through an EHCP appeal, this looks like: emails answered at 11pm, deliverables handed in but quality slipping, leadership decisions deferred, stretch work avoided. None of it appears on an absence report.
The gendered tax on your senior comp
Parent-carer attrition is heavily gendered. The Office for National Statistics, Carers UK and most UK longitudinal studies converge on the same finding: roughly 70% of carers who leave the workforce are women, and the modal age is 40–55.
That cohort — senior, female, mid-to-late career — is the exact population most organisations spend a decade developing for their top three quartiles of compensation. Losing them is mechanically a gender-pay-gap and senior-pipeline problem. Investing in carer-friendly support is one of the few interventions available to a CFO that demonstrably moves the needle on both, with measurable ROI.
A back-of-envelope calculator
A sample calculation for a 1,000-person organisation with an average salary of £55,000:
- ~140 carer employees (1 in 7)
- ~9 attributable leavers per year (mid-point of 7–11)
- Average replacement cost at 100% of salary: £55,000
- Total cost of carer attrition: ~£495,000 per year
That doesn’t include the presenteeism multiple, knock-on team effects, or institutional knowledge loss. Conservative real cost: £800,000 to £1.2 million per year for a 1,000-person UK organisation.
What an intervention buys you
A practical advisory benefit (Beaakon’s session packs, or similar) costs in the low-five-figure range per year for an organisation of this size. Even a single retained senior parent-carer pays back the spend several times over.
The right benefit also produces a quieter, harder-to-attribute return: more confident managers, lower presenteeism, better internal NPS in your DEI surveys, and a story your senior parent-carers can tell at the next networking event. None of those line items appears in a P&L, but all of them compound.
