Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many people have moved on to universal credit during the natural migration phase without having a specific change of circumstance that would require a new claim for a legacy benefit.

Claimants only move from existing benefits to Universal Credit through natural migration when they experience a significant change in their circumstances that triggers a new claim to benefit. Their entitlement is then calculated on the rules of their new benefit.
