Since DH retired last year, he has been on a mission to see how much can be saved without detriment to lifestyle. Every quote for electricity, gas, broadband, phones , insurance (especially insurance) have been ruthlessly bargained over, result? Lots of savings. He discovered that it was better for us to have separate current accounts at Santander rather than keeping savings in a building society, Santander pay 3% on current account balances, building societies were paying 0.5%! I could go on. He has saved hundreds of pounds.
Also occupies him for a couple of hours a week and keeps him off the streets. ?
