Research by the Social Market Foundation and Trust for London estimates that around a fifth (19%) of families with an individual whose main job is self-employment are claiming in-work benefits such as tax credits and housing benefit that will be replaced by Universal Credit. Over 190,000 families have earnings below the minimum income floor and so are likely to be worse off under Universal Credit. London is particularly affected as 18 per cent of those in work are self-employed, the highest rate of self-employment of all UK regions. Furthermore, 67 per cent of self-employed Londoners don't earn the London Living Wage. Will the Mayor raise this as an issue with the DWP, calling for low-paid self-employed individuals being moved from tax credits to Universal Credit to be given a 12-month exemption period from the minimum income floor to give them time to take steps to increase their earnings?
