Matthew White, site manager at latestbettingoffers.co.uk, said: “The latest Premium Bonds draw has seen strong activity in Lancashire, with 301 winners sharing £822,000.
“The perception of safety around Premium Bonds contributes to their ever-growing popularity.
“In 2025, more than 470,000 people opened new accounts.
“Since the money is backed by the Government, people are often more comfortable leaving funds there long-term, even if the returns are unpredictable.
“For many account holders, it’s less about maximising interest and more about the combination of security and a small chance of a life-changing win.”
