Rent arrears meaning (UK): what it is and a simple way to budget the risk
Rent arrears means rent is due but unpaid. For landlords, the key is budgeting a buffer for late/missed payments. Here’s a simple way to model it in your numbers.
The short answer
Rent arrears means rent is owed but not paid. It can happen because of late payments, income shocks, benefit delays, or disputes — but whatever the reason, it’s a cashflow risk for landlords.
The sensible (non-glamorous) fix is budgeting: assume that at some point you may have a missed or late month, and build a buffer into your numbers.
A tiny example
Assume monthly rent is £1,200.
If you budget a buffer of just 1 month’s rent per year, that’s:
- (£1,200 ÷ 12 = £100/month) set aside in a “rent buffer”
Over time, that buffer can cover:
- a late payment that arrives a few weeks later, or
- a short arrears period while an issue is resolved.
It doesn’t remove the risk, but it makes the risk survivable.

If you’re modelling yield, include a line for arrears/late-payment risk (or voids) so your “net” number is realistic.
