London Tops Leaderboard As Highest Growth Buy To Let Market In The Uk

At the start of a pivotal year for the UK’s private rental market, Simply Business, one of the UK’s largest providers of small business and landlord insurance, has analysed over 100,000 landlord insurance policies to uncover the UK’s buy-to-let property hotspots, and point to top investment opportunities for existing, or aspiring, landlords in 2025.The data reveals a dramatic re-shuffle in the buy-to-let leaderboard. London has bounced back as the buy-to-let capital of the UK, with 13% growth in new buy-to-let landlords between 2023-2024, compared to just 4.11% growth the previous year. After stuttering in 2023, London’s strong continued tenant demand and the broad array of property types buoyed the market once more last year.While Glasgow topped the chart in 2022-2023 with 11.95% growth, last year saw it fall back to the bottom of the board, with a much more conservative 7% growth in new policyholders.Mike Harvey, Landlord in London with 25 years’ experience in the market said “The London rental market is performing very well. It’s straightforward to find good tenants, and rental incomes remain strong. As a landlord, I’m also finding that insurers are very competitive at the moment, and I have easy access to a wide range of tradespeople who are always quick to respond when I need help with my properties. We have a 2-unit block and have found these to be the least hassle, with the nicest tenants and best investment return – so we’re very pleased with this position for the short and long term.”UK’s buy to let hotspots2024 Ranking City Region Annual growth* 2023 Ranking 1 London South East 13.00% 10 2 Birmingham West Midlands 12.00% 6 3 Leicester East Midlands 12.00% 5 4 Leeds Yorkshire 11.00% 3 5 Manchester North West 10.00% 7 6 Nottingham East Midlands 10.00% 2 7 Bristol South West 9.00% 4 8 Edinburgh Scotland 9.00% 9 9 Liverpool North West 8.00% 8 10 Glasgow Scotland 7.00% 1 *difference in new Simply Business landlord insurance policies between 2023 and 2024Regulation to reshape the marketNotably, London is also home to the largest group of multi-property landlords in the UK – followed by Manchester, Birmingham and Nottingham
