Buy to let incorporations continue to reach new heights

/

A record 66,587 buy-to-let companies were set up in 2025 according to new research from Hamptons.

Hamptons’ latest Monthly Lettings Index* shows that the number has risen by 8% from the previous high set in 2024, and 363% over the last decade.

Key findings:

  • New buy-to-let firms were the UK’s second-most common type of new company founded in 2025, surpassed only by those offering mail order services
  • By the end of 2025, there were 443,272 active UK buy-to-let companies registered at Companies House – nearly five times (4.9x) the 91,278 recorded in 2016
  • The numbers have continued to rise in 2026, with new incorporations running 11% above the same month last year, suggesting the trend is still accelerating
  • Annual rental growth on newly let homes fell for the seventh month in a row in January, down 0.2%, taking the average rent to £1,366 pcm in Great Britain
