Who is being unreasonable?

We are three working adults and one mid teen.
we all have/buy our own individual toiletries ..even tooth paste … so no arguing about who costs/uses more etc

Toilet roll - at least one a day .
kitchen roll about one a week

Of the 5 of us, I'm the only one at home during the day, so that may account for toilet roll. But, you seem to be getting through a lot!

Toilet rolls - one per person per day but it depends what you buy. Those double rolls easily last two or three days per person, we've had pound shop ones where one roll lasts one "job" so to speak.
Kitchen rolls - one per person per week but again, quality matters
bottles of shower gel - probably a bottle for a family of five should last a week.
Bottles of shampoo and conditioner - if everyone uses it, again a bottle a week.
Fabric conditioner - we don't bother with it.
Washing pods - we use concentrated liquid, two washes per person per week so if it's a pod a time that'd be 10.
Deodorant - a can a week.
Tooth paste - a tube every couple of weeks.
Gas and electric per month - we're tight on heating so it's mainly cooking for gas, about £50 a month. Probably closer to £150 a month for electricity though.

Toilet rolls just disappears!!!
especially with many girls and kids!!!

5, 2 adults, 2 teens and 1 child

4 adults and 1 mid teen here. (4 male 1 female )
Toilet rolls: 12 per month
Kitchen roll: 2 per month
Shower gel: 4 per month
Shampoo 1 bottle guys 1/2 bottle me
Conditioner 1/2 bottle (I'm the only one that uses)
Fabric conditioner 1 x Dettol laundry sanitiser 1.5 litres
Washing powder 1 and a half (40 washes box)
Deodorant: 1 each per month
Toothpaste 4 per month
Electricity £90 per month
Gas £95 per month
4 bed house

Gas is literally just hot water and heating. A bath costs 50p, a shower 15p, washing up is a few pence so it's fine.

Air fryer saved a lot on electric, and I don't have anything big that runs it down really.

I'm on a meter so I monitor it pretty closely.

When I had storage heating a few years back my electric was ridiculous, 60 per week, and about 100 in the winter, and it only went on a set times of the day, and 1 heating of the hot water tank as well. Was so glad to have the gas put in.

Toilet roll 6 per week
Kitchen roll 1 per week if its the good stuff or 2/3 if it's cheaper stuff.
Shower gel 2 bottles
Shampoo 2 bottles
Conditioner 1.5 bottles
Fabric conditioner 1
Washing pods 14 minimum
Deodorant 1 per person every 2 weeks
Toothpaste 1 a week
Electricity around 80 a month
Gas around 75 a month on average

Well I have me and 5 dc here, ones an adult who works, two teens and two under 10, so probably a bit less than you.

I go through a pack of 9 toilet rolls, 1 kitchen roll, shower gel, shampoo and conditioner I buy in 5 litre tubs, but it would probably be 2 normal sized bottles of shampoo and conditioner per week and maybe 2 bottles of shower gel, I do 2 or 3 loads of washing per day so 20+ pods per week and a bottle of fabric conditioner, toothpaste 1 per week, deodorant 1 each per about 2 weeks, gas and electric - I'm about 80-100 per month for electric, winter is about the same for gas, but I'm about a tenner a week from now until October.

I'm in the house all the time and 1 of my dc is home schooled though, 1 at college and working full time, 1 at college and working part time, 2 at school all day.
