@silvercuckoo entitledto and turn2us - the main calculators people use and recommended by the govt THEMSELVES say it is ONLY a guideline and even the result page says
"Our estimate is based on the information you have entered and does not guarantee entitlement."
Or
"This is an estimation of your benefit entitlement and your actual results may differ slightly."
I've just performed calculations on both sites entering entirely accurate information - both gave different results, both overestimate what I should receive and i am absolutely certain I'm getting all I'm eligible for.
And as pps and I have said its not JUST a case of claiming what you're eligible for its all the hoops claimants have to jump through, constant uncertainty "brown envelope fear" is very real, I feel sick every time I hear my post delivered!
You say you're going to "try it" are you even aware you can't just "decide" to reduce your hours or quit your job and claim benefits?!
I believe (though it seems to keep changing) that you wouldn't even be eligible to start a claim for at least 3 months and could quite possibly be considered ineligible for 26 weeks.
There are people with terminal cancer being denied claims!
"If I am wrong, I am wrong, and will simply return to the office in a year, no significant harm will be done." So you have an earning partner or independent income you haven't as yet mentioned? If not what are you and your family going to live on while you're receiving nothing due to being sanctioned for having quit a good job for no reason?
You have absolutely no idea if you think it's that easy!!!!!
