The coronavirus (COVID-19) pandemic led to a series of operational changes to the Household Financial Survey (HFS), from which the Office for National Statistics (ONS) estimates of household disposable income and inequality are derived.
A wide range of financial support measures were introduced to alleviate the potential financial pressure of the coronavirus pandemic; as such, income estimates are subject to greater uncertainty this financial year, and we recommend users exercise caution when interpreting rates of growth, particularly at the quintile and decile level.
Users should be aware that estimates of self-employment income are based on partial returns for the financial year ending (FYE) 2021, with most respondents reporting for previous financial years; estimates are subject to greater uncertainty as a result and may be revised in the FYE 2022 publication.
In response to the coronavirus pandemic, a range of financial support measures were made available during both the financial year ending (FYE) 2020 and (FYE) 2021. For each scheme, there are a range of methodological challenges in accurately estimating their impact.
Coronavirus Job Retention Scheme
The full amount received from any claimant of the Coronavirus Job Retention Scheme (CJRS) scheme during the financial year will be included in wages and salaries. As a result of questionnaire constraints, it was not possible to accurately separate out wages and salaries accrued from working and the furlough scheme.
The treatment of CJRS as wages and salaries is consistent with the National Accounts, which classified the CJRS as a subsidy on production to the employer. It is also consistent with the Canberra Handbook on Household Income Statistics, which states: “Employee income may be received in cash (monetary) or in kind as goods and services…[and] includes: direct wages and salaries for time worked and work done”.
In future publications, we plan to make use of administrative data from the furlough scheme to give more accurate information on how wages and salaries were supported across the income distribution.
Self-employment income support scheme
Self-Employment Income Support Scheme (SEISS) payments during the financial year have not been included in derivation of self-employment income. The National Accounts’ recommendation is to record SEISS payments as a subsidy on production that is payable to those with mixed income and the self-employed. However, there are additional challenges posed by the lag in accounting records for self-employed respondents, as detailed in Section 5.
Future analysis will allow aggregation of self-employment data across reporting years and administrative data to give a more accurate picture on how self-employment income has been impacted by the coronavirus pandemic.
Statutory Sick Pay
New questions were introduced about sickness absence and whether this related to coronavirus or another illness. The amount of statutory sick pay (SSP) received that is refundable by the government to the employer is subtracted from wages and salaries and counted as cash benefit income.
COVID-19 self-isolation support payments
When the COVID-19 self-isolation support payments of £500 were introduced, the HFS initiated questions to capture these. COVID-19 isolation payments are treated as cash benefit income.
Working-from-home tax relief
The HFS questionnaire asks if a respondent has received an extra allowance or claimed tax relief for working from home. This amount is accrued within wages and salaries.Back to table of contents
From our annual statistics, median household disposable income for self-employed people appears more variable than for employed people even before the coronavirus (COVID-19) pandemic. Self-employment income can be more challenging to accurately capture through surveys than employment income, in part because of irregular hours or working on a project-by-project basis, which makes accounting for income across a particular period more complex.
While employed people will typically provide income information from a recent payslip supplied on a monthly or weekly basis, self-employed people may need to refer to verified financial accounts from previous financial years. In doing so, income data for self-employed people may be lagged. While this is an inherent limitation of HFS survey design, it would typically only cause significant challenges when interpreting data on a yearly basis in response to an acute economic shock such as the coronavirus pandemic.
Looking at self-employment income in more detail, within the survey data for the financial year ending (FYE) 2021, 30% of self-employed people reported for the FYE 2021, while an equal amount (30%) reported for the FYE 2020. Table 2 demonstrates how the level and change in self-employment income varies by the period that respondents reported for. Those reporting for the latest period had a median self-employment income of £14,075, which was 4.6% lower than the median value for those reporting for the previous financial year.

In constructing estimates of self-employment income for the financial year ending (FYE) 2021, a range of alternative methods were considered, including analysis of the longitudinal component of the Survey on Living Conditions (SLC) and the use of alternative proxy indicators such as the change in hours worked (which is available for all respondents for the reporting period FYE 2021). However, analysis of longitudinal self-employed income estimates for the subset of households reporting for the FYE 2021 did not reveal any strong correlation between the absolute change in self-employment income and the absolute change in hours worked.
Furthermore, there was no relationship between the reference period (FYE 2021) and the likelihood of reporting a subjective change in household income since the coronavirus pandemic as household perceived income has decreased regardless of the financial year.
Users should treat all estimates of self-employment income with a degree of caution as the estimates are subject to uncertainty. The Office for National Statistics (ONS) will monitor self-employment income returns throughout the FYE 2022, and the ONS intends to produce further analysis of these returns, including potentially a revised set of FYE 2021 estimates in the FYE 2022 income publication.Back to table of contents
Disposable income is arguably the most widely used household income measure. Disposable income is the amount of money that households have available for spending and saving after direct taxes (such as Income Tax, National Insurance and Council Tax) have been accounted for. It includes earnings from employment, private pensions, and investments as well as cash benefits provided by the state.
Comparisons across different types of individuals and households (such as retired and non-retired, or rich and poor) or over time is done after income has been equivalised. Equivalisation is the process of accounting for the fact that households with many members are likely to need a higher income to achieve the same standard of living as households with fewer members. Equivalisation considers the number of people living in the household and their ages, acknowledging that while a household with two people in it will need more money to sustain the same living standards as one with a single person, the two-person household is unlikely to need double the income.
Mean and median income
The mean measure of income divides the total income of individuals by the number of individuals. A limitation of using the mean is that it can be influenced by just a few individuals with very high incomes and therefore does not necessarily reflect the standard of living of the “typical” person. However, when considering changes in income and direct taxes by income decile or types of households, the mean allows for these changes to be analysed in an additive way.
Many researchers argue that growth in median household incomes provides a better measure of how people's well-being has changed over time. The median household income is the income of what would be the middle person if all individuals in the UK were sorted from poorest to richest. Median income provides a good indication of the standard of living of the “typical” individual in terms of income.
Knock to nudge
This is a survey contact intervention that was introduced by the Office for National Statistics (ONS) following the move to telephone surveys in response to the coronavirus (COVID-19) pandemic and national lockdown, with the aim of accounting for a potential decrease in response rate. The knock-to-nudge intervention was implemented for the Household Finances Survey (HFS) from October 2020. It involved interviewers visiting households to nudge those selected to participate in surveys conducted by the ONS while following stringent COVID-19 health and safety protocols. Full details on the knock-to-nudge intervention, and the impact on data collection, are due to be published in Spring 2022.Back to table of contents
