More than half of UK landlords are weighing an exit after a new 4% rental income surcharge, and Savills forecasts rents rising up to 16% by 2031. Our view: don't join the sell-off — defend margins with better operations and tenant retention.

The headline every landlord is reading this week

If you own rental property in the UK, you have probably already seen the number doing the rounds: more than half of landlords are weighing up whether to leave the sector altogether. It is the kind of statistic that makes you pause mid-coffee — and then quietly wonder what it means for your own portfolio.

Here is our honest read on it.

What actually happened

Following Labour's Autumn Budget, a snapshot poll by Propertymark — which represents nearly 20,000 estate agents across the UK — found that 57 per cent of respondents had received enquiries from landlords about leaving the private rented sector in the days after the tax announcement. Those agents collectively held an estimated 2,860 properties on their books.

The trigger is a tax change. From April, landlords will pay a four per cent surcharge on their rental income, after chancellor John Healey doubled a measure already scheduled by his predecessor Rachel Reeves in last year's Budget.

The forecasts that follow are sobering. Estate agency Savills now predicts a 15 per cent rise in average rental costs to 2031, climbing to 16 per cent in London — roughly £2,500 a year more for the average renter, and around £5,000 a year in the capital, on top of rents that are already at a record high.

Lucian Cook, head of residential research at Savills, framed the real risk clearly. As stock is lost, he said, the existing under-supply "becomes more concentrated in those people who remain," creating "a wedge between the haves and the have-nots within the private rented sector." A settled tenant with a long-term landlord is in a good place; someone newly searching has "substantially less choice."

It is worth noting the picture is not one-directional. The same reporting points out that total private rented homes in England now exceed five million for the first time, even as the sector's market share has slipped from 20.3 per cent in 2016 to 19.5 per cent today. Former rentals now make up 15 per cent of all homes on the sales market, with over 800,000 sold off since 2020 according to TwentyEA — most bought by owner-occupiers, which shrinks the rental pool. Meanwhile, the government's position, via an MHCLG spokesperson, is that there is "no evidence of large numbers of landlords leaving," and that the Renters' Rights Act protects tenants from excessive increases.

Our take

It is tempting to read a story like this as good news if you are staying put. Fewer rivals, tighter supply, firmer rents — a seller's market for the ones who hold. We would gently push back on that reflex.

Yes, the owners who remain stand to benefit from the scarcity that others create. But a market that props up rents by removing homes is not a healthy one, and it is not a durable one either. Rising rents driven by shortage attract exactly the kind of political attention that produced this surcharge in the first place. The Renters' Rights Act already hands tenants stronger powers to challenge above-market increases. Betting your returns on scarcity alone is betting against the regulatory tide.

And there is a human cost sitting underneath the numbers. The report features Julie Snowball, 63, who was served an eviction notice on the Runcorn home she had rented for four years at £725 a month — only to find comparable places now advertised above £850. That is the "have-not" side of the wedge Savills describes, and it is a reminder that a thriving rental business and decent tenant outcomes are not opposites.

What this means for you as an owner

Our view: the answer to a tighter, more taxed market is rarely to rush for the exit alongside everyone else. It is to make the rental you keep genuinely worth keeping. Practically:

• Model the surcharge before you react. A four per cent charge on rental income changes the maths, but selling carries its own costs — capital gains, void periods, lost compounding. Run the numbers on your property, not the headline.
• Defend margins through operations, not just rent rises. Fewer voids, faster turnarounds, lower maintenance drag and tighter arrears management often protect yield more reliably than pushing rent to the edge of what a tenant will challenge.
• Keep good tenants. In a market where new searchers face "substantially less choice," a settled, paying tenant is an asset. Retention is cheaper than re-letting.
• Document everything. With the Renters' Rights Act giving tenants room to contest above-market increases, clean records on rent history, repairs and communication are your best defence.

Where this goes next

The owners who come through the next few years well will not be the ones who guessed the market best. They will be the ones who ran their rentals with the discipline of a real business — calm, well-documented, tenant-aware. Scarcity may lift rents for a while. Good operations lift them sustainably, and they keep the regulator off your back. That is the quieter, steadier win, and it is the one we would choose.
