We ain't rich and I'm no Alan Sugar so no major advice for you really however we've managed to bulk up our joint savings a bit since the beginning of year by making a few changes, sticking to a weekly budget and being a lot more conscious of what we're spending.
Simple changes included:
Shopped around for better house & car insurance quotes (saved £80 in total per month)
Changed electricity, TV and internet provider and got cheaper rates. (Tv and internet savings of £30 per month) not sure exactly what electricity change saved us, need to compare bills from previous year
I have noticed that extra £130 per month add up 7 months in.
Moved from bill phone to pay as you go when my contract ended in Feb (often get by on £25 per month, was paying £40 previously) hasn't made a life changing impact and I could do with a new phone but £15 per month saving is still good
90% of our weekly shop is from Aldi now. Still hit tesco for certain things. We buy mostly the same crap every week so we know how much we spend
Batch cook and freeze dinners (cheaper and so convenient) not very exciting but food is good and we're getting a bit more creative
I moved a small amount money from my savings and bought all of DS's clothes for the year in the January sales. Have only had to buy him 1 pair of shoes since then.
We still eat out a good 3 times per month and are working on cutting that back to once per month and save a further £80ish. The novelty of eating out is kind of going so it'll be a win win.
Can your DH take on any extra work? Does he have any skills he could put to use? Catering seems like the kind of industry where you could start small and work your way up? If you drive could you look at a sandwich/lunch delivery service? There's a guy who delivers soup, sandwiches and salads in the business park where I work. He seems to do alright. I think the baking/ cake making side is well covered! Or look into setting up a small cleaning business, might fit in nicely around school times/kids etc?
