I’ve just read these posts and I was a bit worried. I felt sure that if there was a married couple living together then £200 was the qualifying amount - it was £200 for the two people.
I checked the internet and found a link. My hubby got a letter of notification and more or less at the same time £200 was paid into our account. I think you will find from the link that husband and wife do not get £200 each. In case that is what you thought.
You receive £200 winter fuel allowance per house - ie a person living alone receives £200 and a husband and wife receive £100 each. It is increased if you are over 80.
