Imposter syndrome is the persistent belief that your success is undeserved and that someone will eventually expose you as a fraud. For women running businesses or building careers in the UK, it is more than an uncomfortable feeling. It can lead to undercharging, avoiding pitches, staying quiet in meetings or turning down opportunities. Research into imposter syndrome women UK consistently shows a gender gap, with women more likely to doubt their achievements than men. But what is driving that gap in 2026?

Understanding the imposter phenomenon

Imposter syndrome is a pattern of thinking in which people dismiss their achievements, attribute success to luck and live with a fear of being found out. It is not a clinical diagnosis, but it is widely recognised by psychologists and workplace researchers.

The term was first coined in the 1970s by psychologists Pauline Rose Clance and Suzanne Imes, who initially studied high-achieving women. Since then, research has shown the experience is far more widespread. A 2020 systematic review in the Journal of General Internal Medicine found reported rates of the impostor phenomenon range from 9% to 82%, depending on how it is measured.

In the UK, the gender gap is clear. A 2024 Totaljobs survey found that 62% of women and 49% of men have experienced these feelings at work. So while men are not immune, women are more likely to feel them. You can find more context on the position of women in the workforce in our Women in Business: Key UK Facts guide.

The confidence gap in UK workplaces

Psychologists once believed this issue only affected high-achieving women. That idea has been revised, but the workplace environment can still make women more vulnerable. When competence is judged differently depending on gender, it is easy to internalise the message that you do not belong.

Research by KPMG in 2023 found that 75% of female executives across industries had experienced imposter feelings. UK data shows why the feeling is understandable rather than irrational. According to the FTSE Women Leaders Review 2024, women hold 42.1% of FTSE 100 board seats and 41.4% of FTSE 350 board seats. These are record highs, but still short of parity. Only 10 women held chief executive roles in the FTSE 100 in 2024.

The gender pay gap adds to the pressure. ONS data from 2024 showed the median gender pay gap for all employees in the UK stood at 13.1%. A 2024 TUC survey also found that three in five women have experienced sexual harassment, bullying or verbal abuse at work. These realities create a competence bias: women are often expected to prove themselves repeatedly, while men are more readily given the benefit of the doubt.

That bias shows up in everyday behaviour. Research on workplace communication consistently finds that women who speak up in meetings are more likely to be interrupted, labelled as abrasive or judged as less competent than men making the same points. When confidence is punished rather than rewarded, self-doubt can look like a rational response. For women in male-dominated sectors, from tech and finance to construction and engineering, the effect is often magnified. Read more about the broader picture in our article on why the UK gender pay gap could take 30 years to close.

The issue is not simply about individual confidence. It is about who gets to belong. When women in leadership roles are rare, every mistake can feel like evidence that people like you do not fit, while every success feels like a fluke. Our analysis of female CEOs in the UK mid-market hitting an eight-year low shows how slowly the top of business is changing.

Why this is not only a women’s issue

No. Men experience imposter feelings too. Gender does not exempt anyone from insecurity. However, societal expectations often pressure men to hide self-doubt and project unshakeable confidence, which can make the problem harder to recognise and discuss.

Framing it as purely a women’s issue is unhelpful. It reinforces the stereotype that women are emotionally fragile while men are naturally self-assured, which does neither group any favours. It also risks ignoring the men who struggle in silence and the structural barriers that make the workplace harder for women, people of colour, disabled workers and other underrepresented groups.

A more useful approach is to see it as both an individual mindset challenge and a signal about workplace culture. If large numbers of talented people feel like frauds, the problem is rarely just in their heads. Inclusive cultures, where credit is given fairly, voices are heard equally and mistakes are treated as learning opportunities, reduce these feelings for everyone.

Practical ways to rebuild your confidence

Whether you experience it occasionally or it has become a constant background noise, there are practical ways to manage self-doubt and rebuild confidence.

• Record your wins. Keep a running list of achievements, positive feedback and problems you have solved. Evidence is harder to dismiss than anxious thoughts.
• Reframe failure. Mistakes are data, not proof of incompetence. Treat setbacks as part of learning rather than confirmation that you do not belong.
• Talk about it. Share how you feel with a trusted colleague, mentor or peer network. You will usually discover you are not alone. Our guide to women in business networks UK lists communities worth joining.
• Set boundaries on perfectionism. Aim for high standards, but recognise when good enough really is good enough.
• Challenge competence bias. If you are being interrupted, overlooked or asked to take on invisible labour, name it and push back where you can. Confidence grows when your environment treats you fairly.
• Use selective self-belief. Sometimes acting confident helps you feel confident. The trick is to use it as a stepping stone, not a permanent mask.

When self-doubt reflects workplace culture

Employers also have a role to play. The Worker Protection Act 2023, which came into force in October 2024, places a duty on employers to take reasonable steps to prevent sexual harassment of employees. The Equality and Human Rights Commission and ACAS have published guidance on creating respectful, inclusive workplaces.

The Chartered Institute of Personnel and Development recommends that employers tackle these feelings by reviewing recruitment, promotion and pay processes for bias, offering mentoring and sponsorship programmes, and training managers to give constructive, equitable feedback. When workplaces are fair, confidence becomes easier to sustain.

For women returning after a career break, the pressure can be especially intense. Our career returner guide offers practical steps for rebuilding professional confidence in 2026.

Why imposter syndrome women UK research matters in 2026

Imposter syndrome thrives on isolation and silence. The more we talk about it, and the more we fix the workplace cultures that feed it, the easier it becomes to believe that we deserve our seats at the table. A little self-doubt can keep us curious and open to feedback, but it becomes destructive when it paralyses us or distorts how we value our contributions.

Understanding imposter syndrome women UK trends helps us see that the problem is not just personal; it is structural. If you are waiting for the day you finally feel qualified enough, you may be waiting forever. Sometimes the most confident thing you can do is decide that you are already enough.
