How long do rent payments take to process

Hi , we’ve recently moved into a property that we got through open rent . Long story short my payday has changed from the 20th to the 24th and our rent is due on the 25th. If I pay first thing on the 24th will the payment clear by the 25th ?

Explain to the landlord and ask if you can pay a couple of days late each month. Most sensible landlords will allow this without having to change any of the paperwork.
