Use smartprice vinegar (aldi's is currently 13p and edible too unlike asda smartprice vinegar which is vile imho) to descale your kettle and shower head, I put it in the kettle overnight, decant it back into the bottle in the morning and swill the kettle around with cold water before doing the morning tea. A bottle lasts me ages.
Time your hot water tank to only be on for an hour, check the thermostat is set to 60c, I set mine to 55 but I like to live on the edge. When we moved in I couldnt figure out why the gas bill was so much until I realised about the water tank. I set a timer on my phone to remind me when the hour is up.
When your cooking a meal with green veg or baked beans I put them in a pyrex jug in the oven to cook (with water obv) and it saves putting a ring on on the hob, I figure the oven is on so I might as well make use of it rather than putting the microwave on too.
On a day out it's cheaper to buy a multipack of ice lollies than individuals.
If you wash up by hand aldis washing up liquid came out better in tests than fairy.
If you have a dishwasher try tesco daisy powder, it was only £4.59 when I bought mine last November and I am still using it. I use one dessert spoon per wash but I spray the inside of cups with smartprice bleach (I only buy a couple of bottles of it a year too so it isnt expensive) as we use them several times each.
I tried vineagar in the rinse aid compartment but it isnt working out for me so I will be going back to poundshop rinseaid.
You can clean dishwashers using half a cup of soda crystals (cheaper in homebargins than asda) on the hottest cycle, much cheaper than the dishwasher cleaners they sell.
Alwasy check moneysupermarket for vouchers if you go out for a meal somewhere thats a chain, you can usually get bogof or 20% off.
Check supersavvyme for vouchers, I got 20 free dishwasher tablets earlier this year and some vouchers for free always towels, the rest of the time I use sainsburys towels, 14p for 10. They are just like old fashioned towels from 20 years ago and as I dont have heavy periods do the job just fine.
If you need condoms dont forget the family planning clinics do them free as do gp surgeries if you see the nurse to get registered, they are all branded from what I've seen (I used to work in health centres) and different types flavoured, coloured etc.
Some of the water boards offer free water saving devices such as tap inserts, hippo bags and shower regulators (not to be used with power showers though, you'll damage it) or shower timers. Just putting tap inserts in shaved £20 a year off my bill and reduced the amount of hot water being used as dh doesnt always put the plug in.
Homebargains are good for toys, cheaper than argos from what I've seen.
I use card factory for all my birthday and xmas cards now, they arent cheap looking.
MIL uses water from her water butt in the iron as rainwater is soft instead of buying ironing water.
Charity sacks put through your door make excellent bin bags.
Farm foods do the cheapest milk, you can freeze milk so you dont have to pop out to the shops and risk impulse buys or get the car out. We lived in the country for a while with only one village shop that was usually shut so this came in handy.
Stardrops do a gentle wash called alur that I use for my woolens and silks and anything I dont want fading eg nice stuff not workwear, I buy it in homebargains for 89p a bottle.
Smartprice batter mix is only 9pish in asda and does pancakes or yorkie puds.
Dont forget the slow cooker if you have one.
If you need an eyetest check the internet for coupons for free ones or £10 ones. Dont forget if you have a relative with Glaucoma you get free tests (blood relative obv).
You can use wire wool for stubborn stains when you clean, cheaper than brillo pads.
Shop in aldi/lidl. I prefer aldi, it's cheaper and more organised.
Packed lunches.
Try aldi beans, last time we ran out and bought heinz dh told me not to run out of aldi ones again.
Always take a snack and a drink out with you if you are going shopping/nipping into town.
Try sainsbos basics tea bags (I buy 15 boxes at a time), dh still hasnt noticed we dont have pg tips anymore (20 months and counting). Not tesco or asda ones though, there rubbish.
Astonish cleaners are cheap in savers/poundshop and are not tested on animals unlike other major bunny murdering companies.
Find the free side street parking in town and use it, you only get 30 mins but it means you get fit walking really fast too.
Use topcashback, quidco charges £5 a year, they dont.
Find a local farm shop and see if they are cheaper for potatoes etc than the major supermarkets.
Check your local supermarkets at 8-9pm and buy bread for the freezer, 10p for a loaf of Hovis? dont mind if I do ta.
If you have a favorite local eatery join the mailing list, they usually give you a free drink or pudding. Rather have the drink. I have multiple email addresses for this sort of thing.
If you have sky ring up to cancel, they might put you through to customer retentions and reduce your bill rather than have you leave.
Order any pet products you need ie advocate or frontline off online pharmacies via topcashback, even with a private prescription they are half the price.
Check your elec/gas tariffs and go via topcashback, I got £35 for using a search engine via quidco as edf didnt have a cashback deal.
Same for car ins, the cheapest one didnt have cashback but the search engine on quidco did. Add a parent/spouse, sometimes that brings the bill down. When you get your cheapest quote check the retailer website and sometimes you can knock more money off that way. I.E dh's car ins was cheaper via quidco going direct to LV than going through go compare to LV.
I cut and pasted this from previous threads I posted on, I work for myself and when you have to last 6-7 weeks between people paying you you get quite frugal.
I hope something I've posted helps you, I dont miss the days of chucking stuff in the trolley and not thinking about it, I just kick myself for all the money I wasted.
