Blue I don't like the quorn mince either but do like soya mince, think it tastes more like the real stuff (esp if you add half a bottle of cheap red wine in with it
) Morrisons own is quite often on offer 2 bags for £3.
Evil sounds like you are doing all the right things already, although if its just you and a young ds you could probably do better on food maybe? Do you shop at Aldis/ Lidls? I am trying to do alternate week shops there as it is definitely cheaper than the other main supermarkets but I can't always get everything I want from them!!
For me and dd (9yo) I am to spend a maximum of £180 a month on food (less if poss) and this is for all meals for both of us.
Have you had any grief from concentrix yet? I am still waiting to hear as had to send all my childcare forms off. Really unfair and making lots of single parents feel very stressed 
I'm South West as well and think the water rates round here are an absolute joke
if you are privately renting are you bidding for a council place? I have a council flat and it def helps with less rent to pay etc.
Had a lovely day today, lots of free activities going on in town and dds horse riding lesson this afternoon which my mum paid for so actually a NSD. Dd has had a bad stomach this afternoon but hoping it was just a one off.....
