with 6 of you living together £550 isn't expensive and £800 is probably realistic
That works out at £4.30 each person per day - so £1.43 per meal
Whereas you utilities are dubious - sorry
Tv is from memory
14 licence
64 broadband and tv via Virgin
15 Netflix
9.99 Amazon (mainly for delivery)
Do you really need to spend £102 on this? I bet you could ditch the virgin tv and swap to another provider for a year and get a much better deal under £30 for broadband, keep the Netflix and if you watch live tv then obviously you need the tv licence - that would save you £40 a month
Might not seem a lot but if you could do that with all your utitlities... such as Phones for four
£94
Is that smart phones and SIM cards or just the sim contracts? Shop around for far better deals - again you could save on this and add to the savings above.
Why would you give amazon £100 a year so you feel obliged to spend with them?
Also who watches amazon prime and Netflix? Id ask one of the other adult if they want to take over that bill, you pay for the broadband and they can pay for the Netflix and the other adult the amazon prime for the household
