Yes, I spent over 20 years out of work as a SAHM/carer for dd1. We used to get DLA for her, and I was able to claim carer's allowance. DH has always worked, but they've always been low level MW jobs. Every time he's gotten a qualification in something, it's ended up being useless.
DD1 got rejected for PIP when she was 16, as "she looks fine to me", according to the bitch of an assessor. It's taken until now for us to be able to go through the process of reapplying, as after last time, she pretty much had a mental breakdown. She hasn't been recovered for that long.
My job is in admin, I work 45 hours per week but only get paid for 40. The extra 5 hours are for my unpaid breaks, but 9/10 I work through them as our workload is fucking ridiculous. DH is a milkman. Again, he gets paid for around 35 hours per week, but does anything between 40-50.
I know we can complain about workloads etc, but it's a problem in most low-level jobs now. If you can't keep up with the workload, they'll just find someone who will. It's easier to keep your mouth shut, do the work and just keep trying to get another job.
So take home after tax, NI and pension, I get around £1750ish per month, and DH gets £1560 per month. £3310 for everything for 4 adults isn't a lot.
Breakdown of everything;
Rent - £600
Gas/Electric - £450 (paying off debt)
Water - £100 (paying off debt)
Council Tax - £165
Council Tax debt - £230 (paying off bailiffs)
Mobiles - £100 (2 on contract, paying off devices, 2 PAYG)
Car Insurance - £45
Diesel/car maintenance - £100 (DH needs the car to get to work as does permanent nights)
Internet - £65 (need top speed as WFH FT)
Subscriptions/VPN - £66
Gym - £25
Mounjaro - £99
Debt - £112
Groceries (including toiletries etc) - £850 (ish).
I do shop around as much as possible for different deals etc, shop in a mixture of Aldi, Tesco, Lidl and Asda.
