In the first half of 2026, nearly one in five new buy-to-let companies established in the United Kingdom involved at least one non-UK director, marking a significant rise in international participation in the private rental sector. Data from estate agency Hamptons indicates that of the 27,200 buy-to-let businesses created between January and June, 19.5 percent had overseas involvement—an increase of 56 percent compared to 12.5 percent during the same period in 2016.

Indian nationals represented the largest group of foreign directors, followed by investors from Nigeria and Ireland. This marks a shift from a decade ago when the investor profile was dominated by English-speaking and Western European countries, with Irish shareholders leading in 2016, closely followed by Chinese and Indian nationals.

David Fell of Hamptons noted that while the overall pace of buy-to-let company formation has stabilized at around 4,000 to 5,000 per month after years of rapid growth, international engagement remains historically high. Importantly, he highlighted that the majority of purchases involving foreign nationals are made by non-UK residents living within the country rather than direct overseas investors. He also explained that overseas investors often prefer personal ownership over corporate structures due to more favourable tax treatments on rental income in their home jurisdictions compared to the UK’s tax system.

The use of companies to acquire buy-to-let properties has surged in recent years primarily because of tax advantages. Unlike individual landlords who receive only a 20 percent tax credit on mortgage interest, company owners can deduct the full amount of borrowing costs, leading to substantial tax savings. Hamptons estimates that approximately 75 percent of new buy-to-let property acquisitions in the UK are held through corporate entities. The number of buy-to-let companies formed escalated from 10,239 in 2015 to nearly 67,000 in 2025.

The national origins of those investing through company structures have shifted eastward, particularly influenced by immigration patterns and changes related to Brexit. Besides Indians, other nationalities featuring prominently among directors this year include Nigerians, Romanians, Pakistanis, and Lithuanians. Estate agent Benham and Reeves also reported a growing interest in UK buy-to-let properties from Turkish buyers.

Despite the overall international engagement remaining elevated, 2026 saw a slight decline in the proportion of non-UK shareholder directors for the first time since 2015, dropping from a peak of 20.4 percent last year to 19.5 percent. This suggests a modest shift after years of steady growth in foreign involvement within the UK private rental market.
