North London council changes planning rules in HMO crackdown

For comparison, another outer-London borough, Croydon, which during that period operated under the same national rules and the same pressure on housing, refused 66 per cent of HMO applications. The data also shows that Harrow approves 79 per cent of all planning applications, not just HMOs, which is similar to Croydon’s 81 per cent, meaning the divergence is specific to HMOs and not planning in general.
