New figures from Foxtons reveal that overseas applicants now account for roughly two-thirds of all prospective tenants registering with the agency across London, a proportion that underscores just how internationalised the capital's rental market has become. This is not a marginal shift — it represents a structural change in who is competing for the capital's limited rental stock, and it has profound implications for landlords, agents, and domestic renters alike.

The reasons behind this trend are not mysterious. London remains a magnet for international students, finance and tech professionals, and relocating executives, particularly as post-pandemic mobility has normalised and firms have resumed global transfers with fewer restrictions. At the same time, a chronic undersupply of rental homes — the capital has seen active rental listings fall by an estimated 30-40% compared with pre-2020 levels in several boroughs — means overseas renters, often arriving with larger deposits, employer guarantees, or six-to-twelve-month payment offers, are increasingly outcompeting domestic applicants for the best properties. Average London rents have risen by more than 8% year-on-year according to recent ONS and Rightmove tracking, with prime central London postcodes seeing even sharper increases, and this internationalisation of demand is a key contributing factor.

For buy-to-let landlords, this data is broadly reassuring. A tenant pool skewed towards overseas professionals and students typically means lower void periods, stronger rent affordability ratios, and reduced arrears risk, particularly in prime and super-prime postcodes such as Kensington, Chelsea, and Mayfair, where Foxtons has historically dominated. Landlords in these areas are likely to see continued rental growth and competitive bidding on well-presented properties through 2025, even as mortgage costs remain elevated. However, this concentration also creates exposure: any shift in visa policy, university enrolment caps, or global economic conditions affecting expatriate relocation could rapidly alter demand dynamics in a market now so reliant on international inflows.

The picture looks markedly different outside the capital. In cities such as Manchester, Birmingham, and Leeds, rental markets remain dominated by domestic tenants — young professionals, families, and UK-based students — meaning affordability pressures there are driven more by wage stagnation and limited stock than by international competition. That said, Manchester and Birmingham have both seen rising overseas student numbers and a modest uptick in relocating professionals drawn by lower living costs relative to London, suggesting the internationalisation trend may gradually extend to regional hubs, albeit at a fraction of the capital's intensity. Liverpool and Newcastle, by contrast, continue to see rental demand driven almost entirely by domestic factors, insulating them somewhat from the volatility that comes with international demand shocks.

First-time buyers and domestic renters in London are the clear losers in this dynamic. With overseas applicants often able to offer rent in advance or bypass affordability checks that trip up UK-based renters reliant on guarantors, competition for mid-market one and two-bedroom flats in zones two and three has intensified considerably. This is pushing many domestic renters further out, feeding demand into commuter towns across Surrey, Kent, and Essex, where rental growth has accelerated in tandem with London's squeeze. Estate agents in Guildford and Woking report rental enquiry volumes up double digits year-on-year, a trend directly linked to renters priced out of the capital.

Looking ahead six to twelve months, expect this overseas-tenant dominance to persist and likely intensify, particularly if the government proceeds with further reforms to the private rented sector, including the Renters' Rights Bill, which may inadvertently favour financially robust overseas applicants who present lower perceived risk to landlords navigating new compliance burdens. Commercial investors and build-to-rent developers should read this as a clear signal to continue prioritising London schemes targeted at international professionals and students — co-living and purpose-built rental developments in zones one and two are likely to see the strongest yield performance. Developers focused on affordable or mid-market domestic rental supply, however, face a tougher calculus, competing against a tenant base with structurally different financial profiles.

Key Takeaways

  • Overseas applicants now make up roughly two-thirds of Foxtons' London rental enquiries, reflecting deep structural change in tenant demand.
  • Prime central London landlords benefit from lower voids and stronger rent growth, but face concentration risk tied to global mobility trends and visa policy.
  • Regional cities including Manchester, Birmingham, Leeds, and Liverpool remain dominated by domestic renters, offering more stable but slower-growing rental markets.
  • Domestic renters and first-time buyers are being squeezed out of central London, driving spillover demand into Surrey and other commuter counties.
  • Build-to-rent developers targeting international tenants in zones one and two are best positioned for yield growth over the next 6-12 months.
