(We tend to serve most things with salad. Peppers, tomatoes and spinach are good value because they are multi-tasking and versitile. We also do half the week meaty, and the rest veggie)
Use diluted washing up liquid to clean almost everything, a small amount of bleach (its strong stuff, people use too much), cheapo cream cleanser for tough scrubbing, zoflora disinfectant for work surfaces. Buy big boxes of washing powder, mix 50/50 with cheap soda crystals to make it stretch. Use a scoop with a measured sharpie line for recommended amount but use slightly less. Don't guess as its easy to over use.
Go shopping after 7pm and buy bread for the freezer at less than 10p. They also sell sweet treats like apple pies and cream cakes for pences.
Stop eating out and buying ready made food from supermarket. Take sandwiches and drinks with you.
Portion control your food - try and get an extra portion from your dinner to put in the freezer for a later date, or a lunch the next day. Drink more tap water and less tea and coffee.
If you like a drink at the weekend treat yourself to a couple of cans of G&T (85p in lidl) better for you because they are lower alcohol content but still feels like a treat and cheaper than wine.
For personal products don't buy in supermarkets but look in discount stores (as long as you are disciplined not to buy the extra tat). Toothpaste, deodrant, loo roll, shampoo and conditioner, sanitary products, soap, shower gel are nearly always cheaper but obviously know your prices.
