Shocking Study:1 in 3 Brits Admit Hiding Their Salary From Their Partner

A significant shift is reshaping how modern couples manage their household budgets, with new research revealing that one in three UK adults, the equivalent of 16.5 million people, deliberately conceal their earnings from their partner.

While many couples still claim to prioritise financial openness, the Novuna Personal Finance study highlights a growing trend of individuals quietly ringfencing money as a personal safety net. Experts suggest this surge in financial secrecy is less about deception and more a pragmatic, human response to the mounting economic pressures of 2026.

As living costs and housing expenses continue to bite, younger generations are increasingly choosing to maintain a degree of financial autonomy to ensure they remain resilient should a relationship fail.

Younger Generations More Likely to Keep Financial Secrets

The research found notable differences across age groups in financial transparency in relationships. Among younger adults, financial secrecy appears more common. Millennials were the most likely to report keeping financial information private, with around 38% acknowledging they had concealed aspects of their finances from a partner.

Members of Generation Z also reported similar habits, with about 34% saying they had kept financial details private in a relationship. In contrast, respondents aged 55 and older were significantly less likely to report financial secrecy. Only around a quarter of individuals in that age group said they had hidden financial information from a partner.

The findings suggest that younger generations may be approaching money and relationships differently from older couples, often placing a greater emphasis on maintaining some level of financial independence.

Economic Pressures May Influence Financial Privacy

While the survey did not identify a single cause for financial secrecy, economic pressures appear to play a role in how people manage their finances within relationships. In recent years, rising living costs, housing expenses and personal debt have made financial planning more complicated for many households. As a result, some individuals may prefer to keep certain financial decisions or accounts private.

Researchers noted that financial secrecy does not always indicate dishonesty. In some cases, individuals may choose to keep a small financial buffer or personal savings account without discussing it with their partner. These behaviours, the report suggests, may reflect a desire for financial security rather than an attempt to deceive.

Differences in Financial Attitudes Across the UK

The survey also identified differences in financial transparency based on location and living arrangements. For example, respondents living in London were more likely to report keeping financial secrets compared with the national average. Housing status also appeared to influence attitudes toward financial disclosure. Renters were more likely than homeowners to report keeping financial information private, according to the survey. Researchers say these differences may be linked to varying financial pressures, including housing costs and job stability in different parts of the country.

Financial Control Seen as a Major Relationship Concern

Alongside questions about financial secrecy, the study also explored attitudes toward financial behaviour in relationships. The research, conducted with support from the polling firm OnePoll, asked respondents what financial issues they considered major warning signs. Financial control — where one partner restricts another person's access to money — was cited as one of the biggest red flags in a relationship, with 45% of respondents identifying it as a major concern.

Another commonly mentioned issue was asking for financial support early in a relationship. Around 40% of participants said this could be a warning sign, particularly if the request comes before trust has been established. These responses suggest that while some financial privacy may be tolerated, many people still expect fairness and independence when it comes to managing money within relationships.

Financial Stress Among Midlife Adults

The survey also highlighted financial challenges faced by people in Generation X, many of whom balance multiple financial responsibilities. Individuals in this age group are often supporting both children and ageing parents while also managing mortgages, debt and retirement planning. As a result, some respondents reported greater financial pressure compared with other age groups.

The research found that around one in five Generation X respondents said they might struggle financially if a relationship ended, underscoring the economic realities many households face. Some also admitted to hiding financial obligations, such as debts or spending habits, from their partners.

Balancing Privacy and Transparency

According to Theresa Lindsay, chief marketing officer at Novuna Personal Finance, attitudes toward money within relationships are changing. She noted that many couples now aim to balance transparency with a degree of personal financial independence.

While open conversations about money remain important, some individuals feel more secure maintaining a small level of financial autonomy. Experts generally agree that communication about income, debt and long-term financial goals can help couples avoid misunderstandings and build trust over time.
