Just to add to this, the main thing you need to do is cut back on all those unnecessary expenses and then reformulate your budget something like this (have adjusted a few figures slightly for phones and food):-
Total income: £3820.00
Necessary Expenses
DH car loan £270
My car loan £160
Mortgage £645
Water £60
Gas and electric £250
Home insurance £15
Broadband £25
Council tax £190
TV license £15
DH contact lenses £40
DH haircut £15
My haircut £20 (£60 every 3 months)
Window cleaner £15
DH petrol £100
My petrol £100
DH car tax £20
My phone £25
DH phone £25
Food £400
Total: £2390.00
Remaining expenditure budget: £1430.00
(£17,160pa)
Children: £600.00/month (£7,200pa)
(including clothing, family days out/activities, hobbies, holiday childcare, school stuff, birthday party/presents and Christmas presents, gifts for bday parties etc with residual funds going towards annual holiday.
Household maintenance
(1-4% of homes value)
For a home of £200,000 this would be £167.00/month (£2,000pa minimum)
Car costs
Car insurance £470 x2 = £940.00pa
Car maintenance £273 x2 = £546.00pa
Total: £123.83/month; £1486.00pa

Holiday
U.K. about £1500.00 (£125.00pm)
Abroad £3000.00 (£250.00pm)
Gifts for other people/yourselves
£1,000
At top estimate this would leave you with £2474.00
(Probably a bit more as you may hand down items from the older to younger child, you will receive gifts yourselves and there will be residual money from kids allocation that can go to holiday. Even if you don’t spend the money on house/car maintenance it is better to save it for when you need something done rather than end up in debt)
£2474.00/12 = £206.17pm for you and DH to spend on clothes, socialising, hobbies etc.
I would get the cars paid off, or consider having only one car, cut back everything possible until that is done - and consider working more if you want more money for yourselves than this. Kids are expensive.
Incidentally, we save about £2,000 a year using loyalty cards (particularly boots advantage cards). We do all shopping online going via TopCashback first and always search for discount codes on top of this - if I can’t get at least 15-30% off I don’t buy!
