I'm afraid you are right FlicketyB someone just didn't do the maths.
Mishap too with the complexity issues. I have just come across this once again with the Warm Home Discount issued through the energy suppliers. You receive £140 discount off your electricity (I know - why when many more heat with gas ).
There is a core group of people on certain benefits - for pensioners it applies to those on Pension Guarantee Credit - who get it (hopefully) automatically. However, each company has it's "broader group" and (of course), they vary. One thing, anyone on Pension Savings Credit should check with their company as some certainly have this in their broader group.
My mother, for whom I have POA does not get either of the credits but does get some of the disability allowances for those of state pension age. I have no idea whether this means she should get this - it may but I cannot work it out for myself so I will have to rely on the company giving me the right answer. [Growl]
