A local authority is considering the introduction of rent controls. If successful, other councils could use the policy as a template.

The plan is to offer private landlords  financial incentives in the form of loans for capital repairs, if they agree to cap rent rises in line with inflation.

Labour-led Camden Council in London has called in the London School of Economics for a feasibility report, likely to be available this autumn.

The council says it wants to stabilise rent rises. The LSE report will also look at how landlords can be encouraged to offer longer lets.

Both rent controls and longer lets are in line with official Labour party policy.

Julian Fulbrook, Camden’s cabinet member for housing, said: “We have to think hard about carrots as well as sticks.”

Camden’s proposed policy is being followed with interest by other local authorities in London and elsewhere.
