Wealthy Brits are fleeing Middle East turmoil – and pushing London rents even higher
London’s prime rental market is feeling the heat from geopolitical instability thousands of miles away.
As uncertainty grips the Middle East, wealthy British, European, and North American families who had relocated there are rushing back to the UK capital, snapping up short-term lets and adding fresh pressure to an already tight supply of high-end rental properties.
New data from property group Knight Frank shows that demand for prime London rentals surged in March, with the number of new prospective tenants jumping 16.6% year-on-year. For higher-value properties renting at more than £1,000 per week, the increase was even sharper at 16.9%.
This influx is compounding a broader imbalance in the market. The number of new rental listings in prime central London (PCL) and prime outer London (POL) fell 8% in the first quarter of 2026 compared to the same period in 2025, according to Rightmove data.
Overall listings on the platform were 15% below the five-year average. Meanwhile, tenant demand rose 7% over the same quarter.
“We have seen an influx of enquiries from the Middle East for people looking at short-term rentals of six months or less,” said David Mumby, head of prime central London lettings at Knight Frank.
“They tend to be British, European or North American nationals with families who have moved to the Middle East recently, but who already have a network in London.”
A perfect storm for rents
The Middle East factor is only part of the story. A spike in mortgage rates last month, triggered by higher energy costs and inflation expectations linked to the conflict, has prompted more would-be buyers to delay purchases and rent instead while the situation clarifies.
Best five-year fixed-rate deals now exceed 4.8%, more than a percentage point higher than before the escalation.
On the supply side, landlords are increasingly wary. A succession of regulatory and tax changes, capped off by the Renters’ Rights Act set to take effect next month, has made letting properties less attractive.
The new rules introduce greater uncertainty around rent increases, repossession, and the ability to sell. As a result, many landlords have pulled back, tightening availability further.
These dynamics are feeding through to rental growth. In the year to March 2026, rents in prime central London rose 1.2%, bringing the cumulative increase over the past decade to 29%.
In prime outer London, the annual rise was stronger at 2.8%, with values up 24% since 2016. Knight Frank’s PCL lettings index stood at 224.1 in March, while the POL index reached 229.8.
Short-term safety net, long-term squeeze
Many of the new enquiries are for temporary arrangements as families hedge against ongoing geopolitical risks. Even with a ceasefire in place, heightened uncertainty means people are keeping their options open rather than committing to long-term moves or property purchases.
This echoes broader trends in the London market, where buyer demand has also softened amid the turmoil. Knight Frank separately reported an 11% drop in new prospective buyers nationally in March, with London down 6%.
For landlords, the short-term boost in demand provides some relief amid regulatory headwinds. For tenants, however, particularly those competing in the prime segment, it means higher costs and fewer choices.
Tom Bill, head of UK residential research at Knight Frank, noted that the combination of constrained supply and episodic demand spikes is sustaining upward pressure on rents just weeks before the Renters’ Rights Act introduces further changes to the landlord-tenant landscape.
