I agree no-one should suffer from cold, whether a pensioner or a young family.
However, the suggestion that WFA should be linked to Pension Credits would be unfair. I am unable to claim any benefits as I have savings over £16,000. I can see the logic of this as there has to be a cut off point somewhere.
My savings are invested to give me an income which together with my pension is still lower than a friend who receives many benefits because she has told the authorities she has no savings (I know this to be untrue).
If the WFA was linked to Pension Credits I would not receive it meaning I would have to use my savings, reducing my income until eventually my savings would be below the £16,000 threshold and I would then be able to claim all the benefits, thus costing the country much more.
I have put forward the same argument over Council Tax benefit. I can control, to a certain extent, the amount I spend on food etc. but heating costs and Council Tax are out of my control. I have to spend as much as it costs to heat my home and if I don't pay the Council Tax I can be arrested! Perhaps the answer is to raise the savings threshold.
