How Health Conditions Affect Earnings and Employment in the UK: ONS Data Explained

Why This Research Matters

Most personal finance discussions about health focus on treatment costs and NHS waiting times. The ONS research published on 29 June 2026 takes a different approach: it traces the financial consequences of a health diagnosis through earnings records and benefit claims over years, not months.

The findings are significant for anyone thinking about income protection, critical illness cover, or simply how to protect their household finances against the impact of serious illness. The data shows the financial shock is not temporary. For most conditions, earnings remain below the pre-diagnosis baseline for the entire five-year follow-up period. Nor does it begin at the moment of hospital admission - earnings start falling before the first hospital episode, as the progressive nature of conditions affects working capacity before diagnosis becomes acute.

The Conditions Studied

The ONS study covered working-age adults (25 to 64) with first hospital admissions for:

• Cardiovascular disease (including ischaemic heart disease and heart failure)
• Stroke
• Diabetes
• Chronic kidney disease (CKD)
• Cancer (with further breakdowns by cancer type)
• Respiratory conditions (including COPD)
• Musculoskeletal conditions

The study used linked administrative data from three government sources: Hospital Episode Statistics (HES) from NHS England, Pay As You Earn Real Time Information (PAYE RTI) from HMRC, and the Benefits and Income Dataset (BIDs) from DWP. All individual data was de-identified.

Earnings Loss by Condition

Stroke produces the largest total earnings loss across all conditions studied. Chronic kidney disease is second, with an average five-year earnings loss of approximately £14,700 per person. Cardiovascular disease, cancer and respiratory conditions all produce substantial sustained losses.

For context, the average UK monthly earnings in 2023 (the equivalent price base used by the study) were approximately £2,500. A £14,700 loss over five years represents roughly six months of average gross pay.

The Fall in Employment Probability

The study does not only measure earnings loss - it also tracks the probability of remaining in paid employment after diagnosis. Being in paid employment is defined as receiving any monthly pay greater than zero.

For chronic kidney disease, the probability of being in paid work falls by 9.4 percentage points in the fourth year after hospitalisation. This is the sharpest employment impact of any condition in the study.

The Rise in Benefits Receipt

Alongside the fall in earnings and employment, the study tracks the probability of receiving benefits - including Universal Credit, Personal Independence Payment (PIP), and Carer's Allowance.

The probability of receiving benefits rises across all health conditions studied after hospital diagnosis. Critically, this rise begins before hospitalisation for most conditions, reflecting the gradual progression of serious illness before it becomes acute enough to require hospital admission.

For CKD, the probability of receiving benefits rises by 16.3 percentage points in year 4 - the largest increase of any condition in the study. This reflects both the severity of CKD's impact on working capacity and the relatively low baseline rate of employment among those who develop the condition.

The Pre-Diagnosis Earnings Fall

One of the study's most important findings for financial planning is that the earnings impact begins before hospital admission. For progressive or chronic conditions, earnings start falling in the months and years before the first hospital episode, as symptoms begin to affect working capacity.

This has two implications. First, five-year figures understate the total financial impact because they do not capture the pre-diagnosis period. Second, by the time a diagnosis is confirmed, some of the financial damage has already occurred - making pre-diagnosis financial resilience (savings, existing protection policies) more important than post-diagnosis cover alone.

What This Means for Income Protection

The ONS data provides an evidence base for why income protection insurance exists as a product category. The financial consequences of serious illness are not short-term disruption - they are sustained multi-year income reductions that begin before the formal diagnosis moment that protection policies use as a trigger.

Points relevant to income protection decisions:

• A deferred period of 13 or 26 weeks (common in income protection policies) may mean the benefit kicks in after some of the initial earnings shock - check waiting periods carefully
• Critical illness cover pays a lump sum on diagnosis of specific conditions - it does not replace ongoing income, so it and income protection serve different purposes
• State incapacity benefits (principally Universal Credit with a limited capability for work element, and PIP) replace only a fraction of pre-illness earnings for most working-age adults
• Employer sick pay provisions vary widely - statutory sick pay is £116.75 per week (2026/27) and lasts a maximum of 28 weeks

Multiple Long-Term Conditions

The June 2026 GOV.UK publication specifically covers the impact of cardiometabolic multiple long-term conditions - where a person has two or more conditions simultaneously, such as both cardiovascular disease and diabetes or both CKD and hypertension. The financial impact of having multiple conditions is compounded. Earnings losses are larger and employment probability falls more steeply than for any single condition in isolation.

This is increasingly relevant: the prevalence of work-limiting health conditions rises with age, from approximately 10% of those aged 30-35 to 19% of those aged 50-55 and 26% of those aged 60 and above (ONS, 2024). As more people work into later life, this age-related clustering of conditions becomes more consequential for retirement income planning.

What does the ONS research on health conditions and earnings show?

ONS research linking hospital admission data to HMRC earnings records for over 45 million working-age people shows that every major health condition studied - including stroke, cardiovascular disease, CKD, diabetes and cancer - causes sustained earnings losses and reduced employment probability lasting at least five years after hospital admission.

Which health condition causes the biggest earnings loss in the UK?

Based on the ONS dataset covering April 2014 to December 2022, stroke produces the largest average five-year earnings loss of all conditions studied. Chronic kidney disease is second, with an estimated five-year loss of approximately £14,700 per person.

Does the earnings impact start before a health diagnosis?

Yes. The ONS study found that for progressive or chronic conditions, average earnings begin falling before the first hospital admission, as symptoms affect working capacity before the condition becomes acute enough to require hospitalisation.

How does a health condition affect the probability of receiving benefits?

The probability of receiving benefits including Universal Credit and PIP rises after hospital diagnosis for all conditions studied. For chronic kidney disease the rise is 16.3 percentage points in year four - the largest increase of any condition. This rise also begins before formal diagnosis for most conditions.

What financial protection exists if a serious health condition affects my earnings?

State support includes Statutory Sick Pay (£116.75/week for up to 28 weeks) and, depending on the condition and circumstances, Universal Credit, PIP or Employment and Support Allowance. Private options include income protection insurance, which replaces a proportion of salary while unable to work, and critical illness cover, which pays a lump sum on diagnosis of specified conditions. Both are regulated by the FCA.
