I've managed on the basic state pension for 12 years now. I run a home [no mortgage] and have a car to keep on the road, I have all bills and 75% council tax to pay on my own.
It's doable but I have a simple life out of choice, few holidays which are spent in the UK in holiday cottage split costs with a friend. I eat well, cooking from scratch every day, my hobbies are reading, gardening, walking, writing, renovating furniture, DIY. I [pre-covid] eat out now and then, and have many days out. I'm content with my life and family and don't feel I'm missing out or deprived at all.
However I have a lump sum of savings from an inheritance tucked away which means I do not qualify for pension credit. But I have never had to dip into those savings for everyday living costs, my pension takes care of it all. It means though that I wouldn't have any problem if I needed expensive house repairs or replace the car for example.
So I feel secure and have no money worries. Without this maybe I wouldn't feel so comfortable. If someone has a property there is always the option of releasing some equity if it means making life bearable...but only a reasonable amount and later years.
