You won't be the first to do this. I know someone who purposely does a smaller amount of hours every March or April, to drop her normal monthly wage of £1150-ish to £800-850, so she can fill in an HC1 and get full help with health costs all year. Free prescriptions, free dental, £60 voucher towards glasses, free eye tests, help with travel costs to hospital or specialists etc....
£350-ish wage loss to potentially save multiple 100s over a year. (£750 to £900 typically.) She doesn't have to worry about a filling dropping out or a tooth chipping or needing multiple prescriptions etc, as it's all covered.
That's how ridiculous things are in this country. You are only OK if you're a very high earner/rich, OR if you are financially poor, coz you get lots of help from the Government.
I know a few people who are/were on less than £20K a year joint income whose young adult children got 1000s thrown at them in grants and bursaries, and they had more money at uni than many students who had parents on £45-55K a year joint income. The ones whose parents were proper loaded were OK, but the students of the middle earners were fucked, because they got NOTHING, but their parents were not well off enough to give them anything.
@Bucketheadbucketbum Ignore the naysayers and the haters calling you grabby and lazy etc... they're just jealous and bitter. Most people would give their left arm to work only 3 days a week and have more time with their children. And as I say, it's the SYSTEM making you do this. If most jobs paid a lot better and gave people good money/plenty of surplus income, people would not be inclined to do this.
