Morning
I've just received an email from TfL about changes to the Oyster Auto Top-up feature.
From Sunday 17 November 2019, Oyster Auto Top-up will take place when balance falls below £20.
Currently it happens when balance falls below £10.
Looks like I'll have to reconsider using that feature. Having £20 tied up on my Oyster card feels completely different psychologically compared to only £10. No doubt this is linked to the higher fares charged once you go west of West Drayton

From Sunday 17 November 2019, the Auto Top-up threshold will change to £20. From this date, your Oyster card will be topped up with your chosen value when your balance falls below £20.
You will also see Auto Top-up charges more quickly in your bank account. If we are unable to collect payment for your Auto Top-up, your Oyster card will be stopped.
If you currently pay an adult fare, you can travel with contactless if you prefer not to continue with Auto Top-up after these changes are made.
When you use contactless to pay as you go, you are charged the same adult fares and daily caps as Oyster. You can also benefit from weekly (Monday to Sunday) capping, meaning you won’t pay more than the price of the equivalent 7 Day Travelcard.
