Plum Launches Sunny Day Rule to Boost Summer Savings
By Lauren Towner · 12 August 2025

Smart money app Plum has launched a new Sunny Day Rule to help users boost their savings this summer.
Each time the app receives data confirming it’s sunny in their registered location, Plum will automatically set aside money for customers who have activated the rule. The new automation has been inspired by the popular Rainy Day rule, which sets aside a particular amount of money each time it rains.
The Sunny Day Rule offers users five different modes to help boost their savings. These include:
- Shady Spot - Sets aside £1 when activated
- Sunny Side Up - Sets aside £2 when activated
- Summer’s Here - Sets aside £5 when activated
- Beach Day - Sets aside £10 when activated
- Blazing Hot - Sets aside £20 when activated
