OP
Ask him how much he thinks you should be spending for entertainment purposes.
I think the above quoted ONS figure for an 'average' family smacks of the poverty and poor diet of far too many in this country. How the hell is that the 'average' family. Who the hell is buying all the branded stuff then?!
What you have meal planned looks pretty fine and not excessive. Maybe there's a bunch of stuff you are not accounting for in there. But crucially it's healthy and balanced.
Ask him how much 4 pints of milk, a standard non branded, none economy loaf of bread, a tin of tomatoes, a 400g block of cheddar cheese, 500g of pasta and a 500g packet of mince costs.
Aldi mid range prices
4 pints - £1.79
Loaf of bread - £0.74
Tin of tomatoes £0.47
400g block of cheddar - £2.49
500g pasta - £0.69
500g mince - £2.49
£8.67
Aldi economy prices
4 pints - £1.79
Loaf of bread - £0.47
Tin of tomatoes - £0.39
400g block of cheddar - £2.49
500g pasta - £0.41
500g mince - £2.29
£7.84
Going economy would save you £0.83.
None of the above is extravagant.
If you are cooking from scratch (which everyone really should be for their health), it's easy to see how £63.50 isn't really very likely to cover 3 healthy meals a day.
It's interesting to look at Asda's take on this.
Asda do a bimonthly magazine which does a 'week' shopping basket of food. The July/August edition came in at £25. BUT it was just five meals! And assumes you already have things like that expensive bottle of oil. So they are budgeting £5 per day or £1.25 per person for each meal. And you still have another 2 evening meals, breakfast, lunch and things like tea, milk, coffee, oil to budget for.
Two of the meals are vegetarian. One uses fish pate, one uses chicken drumsticks and the other pork mince. Even more telling is one of those meals works out at 283 calories per portion and another 367 calories. They are REALLY going for the cheapest possible options with that. It's just not going to come close to the needs of four adults unless they are all super tiny like me. And you are only going to go with those options if you really are struggling - they aren't standard options by choice. They are choices which are by necessity. And the shopping basket plan is in effect something of a fudge to look good on the surface for publicity purposes but look a bit closer and it's not as good as first impressions might suggest.
£100 per week for a family of four adults is probably far more realistic as your base line for not eating total crap, not skipping meals and cooking reasonably healthy taking everything into account.
Indeed, looking at the link PassCaring put above it states:
£29.66 per person per week was spent on household food and non-alcoholic drinks
That's £118.64 for four. That seems much more in tune with reality. (This doesn't include your household expenditure either). And sounds in tune with what most posters here are saying.
The OPs shopping does have none totally basic stuff on it. But I'd also argue it's not excessive either. It's mid range in terms of choices.
Yes there's probably room for improvement, but the OPs DH certainly isn't reasonable either.
