As the hon. Gentleman will understand, the estimates of how many people might be eligible for pension credit are an imperfect science—they are based on a survey. Means-testing what is a very complex benefit, as all means-tested benefits are, requires an assessment of not only people’s income but their savings; it is about pensioner household units, too, so it is a complex set of procedures. All I can say is that I am glad we are targeting support at those most in need, something that was outlined in the 2017 Conservative party manifesto, which stated:

“we will means-test Winter Fuel Payments, focusing assistance on the least well-off pensioners, who are most at risk of fuel poverty.”
