Cash is king, do not be deluded by plastic tech.
Cash saves a few quid on many purchases and building work.
I try to always have good few quid in cash about as you never know, the banks cash machine system might crash the next day etc.
Always keep at least £50-100 cash min around.![]()
One of the lessons I learned when my Dad died was that actually £5000 in an envelope is actually about the most useful thing you can possibly have!
(All other accesses to spending money dries up very quickly after a death and yet you are expected to deal with it all within a week or so!, (you can get it back eventually, but not necessarily at the time!))
If you have elderly parents to consider, this is something to bear in mind!
