Zoopla expects UK rents to climb 4-5% by year-end, driven by shrinking supply and weak landlord investment rather than tenant demand. It's a fragile, scarcity-led rise, so owners are wiser to invest in retention and efficiency than aggressive pricing.

Here is a headline that sounds like bad news for tenants and good news for owners, and is really neither: UK rents are set to rise 4% to 5% by the end of the year, and the reason is not landlord greed but landlord absence.

What Zoopla is actually saying

According to Zoopla's latest rental market report, reported by Property118, the supply of rental homes has fallen for the first time in three years. Availability began dropping in May, reversing the supply recovery that had helped slow rent rises across 2024 and 2025. There are now 3% fewer homes to rent than a year ago, and August supply was 6% lower.

The forecast follows from that squeeze. Rents were 2.6% higher in the 12 months to July, up from 1.6% annual growth in February, with the average now standing at £1,340 a month. Zoopla expects growth to reach 4% to 5% by year-end.

Zoopla's executive director, Richard Donnell, pins it on two forces pulling in the same direction:

"Low levels of new investment by landlords and renters renting for longer mean we expect UK rents to increase by 4-5% by the end of the year."

Higher mortgage rates, he notes, are keeping would-be first-time buyers in rented homes for longer, tightening supply just as seasonal demand picks up. And crucially, the report is explicit that in many areas it is falling availability, not fiercer competition between tenants, doing the work.

The geography makes the point. Yorkshire and Humberside saw a 12% fall in homes to rent; London was 6% lower. Wales moved the other way, with availability up 7% and rent growth slowing more sharply than elsewhere. In smaller markets with fewer landlords, the swings are sharpest: rents in Dumfries have risen 11.3% and Carlisle 8.8%. Cheaper homes, below £750 a month, have risen 5.4% — more than twice the national rate.

Our take: this is a symptom, not a strategy

We want to be plain about what this data does and does not show. It is tempting to read "rents up 4-5%" as owners flexing pricing power. That is not what is happening. The rise is being manufactured by thinning inventory, and thinning inventory is the visible result of owners quietly leaving.

Knight Frank's Tom Bill put the cause bluntly, describing "years of tightening supply as landlords left the sector due to a proliferation of red tape and taxes," and adding that for those who stayed, the Renters' Rights Act "has aggravated the situation further, with some landlords setting asking rents higher to compensate for the increased risks they face around void periods, rent collection and regaining possession."

So the increase is real, but it is fragile. A rent rise driven by scarcity rather than genuine demand is only one policy change or one cost shift away from reversing. Propertymark's Nathan Emerson and Zoopla both land on the same conclusion — that the sustainable route is more good-quality supply, not tighter supply. We agree. An owner who reads a supply-driven number as permission to push pricing to the ceiling is building on sand.

What this means for you as an owner

If you own and rent out property, the interesting move here is counter-intuitive. The market is handing you upward pressure on rents you did not create. The temptation is to bank it aggressively. The smarter play is to treat this window as a chance to invest in the things scarcity can't fake.

• Prioritise retention over re-listing. A rise driven by low availability means every void period is more expensive and every re-let is more disruptive. Keeping a good tenant who pays on time is worth more than a headline rent you might not sustain. Price renewals to keep people, not to test their patience.
• Read your own local supply, not the national number. The gap between Yorkshire's 12% supply fall and Wales's 7% rise shows how meaningless the average is on the ground. What matters is availability in your postcode and your price band.
• Tighten operations while margins are kind. Some landlords are raising rents specifically to offset risk around voids, arrears and possession. The better hedge is fewer voids and cleaner rent collection in the first place — the operational discipline that holds up when the pricing tailwind fades.
• If you're the type LRG describes as an "established investor," look where yields improved. With falling prices in London and the South East lifting yields, some serious landlords are expanding rather than exiting. That is a legitimate read — just one grounded in numbers, not in a scarcity story that could turn.

The owners who come out of this well won't be the ones who squeezed hardest during a supply pinch. They'll be the ones who used a calmer patch to make their properties easier to run and their tenants happier to stay. Scarcity-driven rent growth rewards nobody for long. Good management does.
