To reiterate, we have not taken any money out of the system. We are, rightly, targeting support at those who need it the most. For example, under legacy benefits, those on employment and support allowance would have expected to get £160.05 a month, but under universal credit it is significantly higher—in fact, more than double, at £336.20 a month. That is why over 1 million households with disabled people will on average be over £100 a month better off.
That goes hand in hand with our attempts to simplify the system. We are taking seven disability premiums down to two. The legacy system was difficult to deliver, prone to error and often confusing. Under the legacy system, over £2.4 billion of benefits went unclaimed every year. Some 700,000 of the most vulnerable people were, on average, missing out on £280 a month.
In addition to this support, many claimants will be entitled to support with personal independence payment, disability living allowance, attendance allowance or adult social care. Those going through the managed migration will get full transitional protection. We went further with good intentions by introducing the gateway on 16 January, including for those with changed circumstances. We will be considering all options in the light of the judgment and we will update the House in due course.
