To help with this, I came across this fantastic website from Leeds Building Society: http://www.leedsbuildingsociety.co.uk/resources/kick-my-habits/
This website steps you through some common spending habits and allows you enter what you spend on these. The habits are: takeaways, alcohol, cigarettes, nights out, beauty, lunches, technology and evenings out. Here are a few of the pages of what we entered: Takeaways - typically a Chinese or an Indian, though now and again we do have pizzas to not be too predictable!
Lunches out - with young children, we tend not to dine out in the evenings so lunches out are our most expensive habit.
Technology - I've not counted landline/broadband here and this spend is predominately our mobile phone bills but we do spend a little on apps too. 
Evenings out - this is mainly trips to the cinema.
After stepping through all the habits, it summarises your total weekly spend or saving if you were to kick these into touch:
Shockingly, ours came to £97 per week which could be a saving of £5044 per year plus over £83 of interest! It's certainly good food for thought and a good lesson of how we can be more frugal. Have a go - it doesn't take long - and let me know how much you could save!
Disclosure: This is a PR Collaboration.
