Side Hustle Boom: 1 in 5 UK Adults Now Boosting Income with Extra Work
Survey: Nearly 20% of UK Adults Have a Side Hustle

New research has revealed a significant shift in the UK's working habits, with a substantial portion of the adult population now turning to additional ventures to supplement their income.

Who is Taking on Extra Work?

A comprehensive survey commissioned by the financial services provider Scottish Widows indicates that nearly one in five (18%) adults in Britain currently has a side hustle or additional job. The research, conducted by YouGov in August 2025, gathered responses from more than 2,500 people aged between 18 and 50 across the nation.

The data shows a slight gender divide: 18% of men report having a side venture, compared to 17% of women. However, the preferred methods for generating this extra income differ between the sexes. For women, buying and reselling items on online marketplaces is a particularly popular route. Men, on the other hand, are more inclined towards freelance work, which includes creative tasks like designing and writing, or service-based roles such as pet sitting.

How is the Extra Money Being Used?

The motivations and uses for side hustle earnings vary dramatically depending on an individual's primary income level. The survey highlights a crucial distinction: those on lower incomes are far more likely to rely on their additional earnings to cover everyday living expenses. For higher earners, the extra cash is typically saved or invested, providing a boost to their long-term financial security rather than addressing immediate needs.

Building Financial Resilience for the Future

Susan Hope, a savings expert at Scottish Widows, emphasised the strategic value of a side hustle. "A side hustle can be a practical way to boost your income no matter what your situation is," she stated. Hope advocates for a proactive approach to the extra funds, suggesting that investing the income is a smart strategy for long-term growth.

"Investing the income from your side hustle is a smart way to make your money work harder for you and grow over the longer term, helping you achieve your long-term financial goals," Hope explained. She also proposed a novel perspective, adding, "Thinking of investing as a side hustle could also help more people build up financial resilience to face into life’s unexpected costs. It’s about small amounts that add up over time."

This research underscores a growing trend of financial pragmatism among UK adults, as millions seek innovative ways to enhance their earnings and create a more secure financial buffer in an uncertain economic climate.
