Wear clothes a few times before washing. Towels used twice before washing. Hang wet clothes on hangers from the shower rail to dry (creases drop out). If anything needs an emergency wash and there's space, I strip cushion covers and chuck them in too. Outfits for next day ready night before.
Last bit of washing up liquid, bath foam, shampoo / conditioner gets watered down a little (helps it come out easier). Refill soap dispenser with cheap bath foam. Swapped to soap rather than shower gel to save money / plastic. Everyone has their own. Make up zoflora to refill dettol bottle.
Prep lunches the day before for work. If I make pasta, I use a slotted spoon to remove the pasta and then boil eggs in the left over water. When making a roast, make extra portions & plate up ready for heating up for an easy dinner the next day.
Batch cooking & meal planning. Soups are great for using up veg which is a bit wrinkly. I turn the oven off a couple of minutes early. Also leave the oven door open after cooking to warm the kitchen a little.
I don't eat meat and dh has cut down to save £ / environment / animal welfare. Only buy reduced meat, remove from packaging & portion up in bags in freezer to save space.
We stock up when something is on offer to save £ & and jumbo packs of cat food.
Shopping list stuck to fridge, if something's running low it goes on the list.
Old vacuum upstairs & new one downstairs to avoid lugging them up / downstairs.
One full bag for life to the charity shop a week. Filled throughout the week.
Gift / wrap drawer & cards from the card factory (10 for £1, sometimes 20 for £1).
Buy second hand books in charity shops / eBay / go to the library.
Anything that needs to go upstairs is put at the bottom of the stairs ready to take it up on next trip.
