Buy-To-Let Company Formations Fall 8% in Early 2026
New buy-to-let limited company incorporations dropped 8% in the first eight months of 2026, signaling a potential peak in the structural shift driven by tax changes.
Buy-to-let company formations fell by 8% in the first eight months of 2026. This marks a drop from 44,802 new entities in the same period of 2025 to 41,483 in 2026. The decline suggests the rapid growth in corporate landlord structures may have peaked.
August showed a sharper contraction. Incorporations fell 22% year-on-year to 4,198. This pushed buy-to-let businesses to the fifth most common new business type. Mail order and online sales companies now lead new registrations with nearly twice the volume.
Portfolio transfers have peaked
Hamptons data indicates the market has passed the peak of existing portfolio transfers. In 2025, about 43,400 properties moved from personal to company ownership. This represented 53% of all property placements into limited companies. Most landlords who benefit from incorporating have already made this transition.
Remaining transfers face significant upfront costs. Average Stamp Duty bills on these transactions are approximately £28,000. This is based on an average property price of £380,000. Capital gains tax also applies, making the move unviable for lower-rate taxpayers or those planning short-term exits.
Total landlord stock continues to rise
Despite the slowdown in new formations, the total number of buy-to-let companies is increasing. By the end of August 2026, 469,165 buy-to-let businesses were operating in Britain. This is up from 443,272 at the end of 2025. New incorporations continue to outpace closures.
If the current trajectory holds, 2026 will mark the first full-year decline in new formations since 2008. The Treasury currently generates around £1.2 billion annually from Stamp Duty on these transfers. This revenue may dip as incorporation rates slow.
Rental growth accelerates outside London
Annual rental growth for new tenants reached 2.4% in August. This is the fastest level of growth since November 2024. The average rent for a new home reached £1,419 per month. Growth was highest in the South West at 5.4% and the South East at 3.75%.
North of England rents passed the £1,000 monthly mark for the first time. Rents rose 2.8% to £1,014 per month. The average rent paid by all tenants rose 2.0% to £1,260 per month. This is £159 less than what a moving tenant pays. GN auto markets/housing: rental market data confirms these accelerating trends.
