Cover of The UK SME Funding Handbook by Castle FD

Funding isn't the problem. Access is.

There has never been more choice of business finance in the UK, yet the door to your own bank is harder to open than it used to be. A "no" rarely ends the search. More often it moves you to lenders who say yes faster, and charge far more for it.

48%

of smaller businesses are confident their bank would lend, down from 65% in 2016

35%

of SME finance applications declined, Q3 2024 to Q4 2025

60%

of gross SME bank lending in 2025 came from challenger and specialist banks
