Here are UC statistics directly from the government.
In June 2025, 9.7% of people on UC were in the “EU Settlement Scheme” group. 2.7% of people on UC were in the “Indefinite Leave to Remain (not EU Settlement Scheme)” group. 1.5% of people on UC were in the “Refugee” group. 1.0% of people on UC were in the “Limited Leave to Remain (not EU Settlement Scheme) including family reunion” group. 0.7% of people on UC were in the “Humanitarian” group. 0.4% of people on UC were in the “Other” group
So even if you remove every single person with ILR, but not Settled Status (as Reform say they won't), you are in fact losing 2.7% of your UC bill at most. But then... 32% of this 2.7% are employed.
These threads are always full of people complaining that people aren't reading what Reform is actually saying but often without checking the statistics they are offering up themselves.
@charliehungerford your stats could relate to the number of people currently living in London who are first generation immigrants going back decades. Of new social housing lettings from 23-24, 76% were of White British ethnicity, and 81.6% overall were White, with White other making up 5%. New tenancies are broadly in line with the ethnic make up of the UK as a whole. In terms of nationality, 9% of new tenancies went to people from outside the EU, including 0.6% from Ukraine and 0.4% from Afghanistan. This is higher than the non-EU proportion of the UK population which is 3% and has doubled in the past three years. 87% of new tenants are UK nationals, slightly lower than the 91% percent of the population they comprise.
Overall a third of new lead tenants are in work, followed by carers, people unable to work through sickness, and pensioners. Only 13% are counted as unemployed and seeking work.
