Claimants signing on to universal credit from this week will not receive any income before Christmas because of the existing 42-day wait for payment, putting the finances of tens of thousands of households at risk, according to a housing association.

The Peabody Trust estimates that nationally more than 60,000 households, containing more than 40,000 children, will make new universal credit claims in the six weeks before Christmas, and so will not receive any income in the run-up to the festive season. The trust calculated that even if the wait were to be cut to four weeks, 27,000 children across 40,000 households would still be affected. Reducing the wait to two weeks would leave an estimated 20,000 households, containing 14,000 children, at risk of having no cash over Christmas. The lengthy wait for a first payment has been blamed for spiralling rent arrears and rising food bank referrals. More than half of new low-income claimants are used to budgeting on a weekly or fortnightly basis, and few have savings.

Although ministers have signalled that they are prepared to shorten the waiting time to four weeks, campaigners have warned this may still be too long for many households, and that further cuts to the waiting time should be considered.

On Wednesday it emerged that a private landlord in Grimsby had formally warned tenants on universal credit that it would move to evict them if they were unable to meet rent payments. New claimants in north-east Lincolnshire will move to universal credit on 13 December.
