Hmm without knowing exactly what you are already doing I would suggest the following:

- ensure you have a meal plan and shopping list to shop according to need and cut out any 'treats' or non-essentials
- make bulk meals and freeze or stock up on non-perishables while you still have income
- use bicarb & vinegar for cleaning
- cycle or walk where possible to avoid using the car and petrol
- look for the cheapest insurance options for house and car
- get a capped mobile phone plan
- run a cash budget so you don't use cards for any purchases.
