Household Cost Pressures Highlight Need for Landlord Cash-Flow Planning
New ONS figures show a majority of adults in Great Britain report rising living costs, prompting a reminder from Property118 that landlords should distinguish between a rent schedule and a genuine cash-flow plan. The site argues that a property can produce a respectable annual surplus while still leaving its owner short of cash when a bill falls due.
Writing for Property118, Mark Alexander sets out why the distinction matters, particularly for landlords who rely on their portfolio to provide a dependable income, fund retirement or reduce the time they spend managing it.
What the ONS data shows
The ONS August bulletin, published on 18 September 2026, reports that 55% of adults said their living costs had increased compared with a month earlier, while 62% said they had been very or somewhat worried about rising living costs during the previous fortnight. The survey covers adults aged 16 and over in Great Britain, excluding Northern Ireland, with fieldwork conducted between 5 and 30 August.
Property118 is careful to note the limitations of this evidence. The figures describe adults generally, not private tenants specifically, and do not establish how many tenants will pay late. The publication points to its separate report on rents and tenant budgets for affordability pressures, and advises owners to test their business's resilience to interruptions without making assumptions about individual tenants from national statistics.
Stress-testing a cash-flow plan
The article uses an entirely illustrative example: a property receiving £1,200 a month, with a £650 monthly interest-only mortgage payment at an assumed 6% annual rate on a £130,000 loan, plus £150 of other recurring payments, leaving £400 a month before tax. Opening cash of £4,000 is assumed. Property118 stresses these are planning assumptions, not market averages, reserve targets or ONS forecasts.
Three scenarios are tested:
- Delayed rent: If no rent arrives in month one, the business draws £800 from opening cash. If the overdue rent is paid in full the following month, closing cash recovers, but the first month's funding need is real, and recovery is an assumption.
- A one-month void: The initial cash movement is the same, but there is no overdue rent to collect. Property118 notes actual void costs may differ from occupied costs, with possible reletting charges, utilities and council tax to consider.
- An essential repair: A £1,800 repair paid in a month when rent arrives normally still reduces cash significantly, as the month's ordinary surplus cannot absorb it.
What this means for agents and clerks
For letting agents and inventory clerks, the practical takeaway is that timing matters as much as the amount of rent agreed. The dates money reaches the landlord's bank, and the commitments it must meet, deserve equal attention when advising on void periods, relets and maintenance scheduling.
