If winter fuel payment is to be means tested that clearly means that only the pensioners on pension credit wiill get it. That is the least expensive way of administering it.
When trying to find out how many will still get I could only find this official figure -

"Pension Credit - Parliament UK
researchbriefings.files.parliament.uk/documents/SN01439/SN01439.pdf
Currently, just under half of pensioners (45 per cent) are eligible for Pension Credit to top up their state pension. .
It is also worth noting that Pension Credit is not claimed by around a third of pensioners who are entitled to it,"

So only 66% of 45% will get it - i.e. 2/3rds of less that half of all pensioners = massive savings for the exchequer.

When pensioners realise this there will be a drop in the tory vote.
