Meters have always been replaced as their calibration periods expire.

In theory, ours are dated 1967, 1980 and 1996... The two digits in
the first part of the meter number are its calibration year.

The first two are mechanical, the 67 one almost certainly "out of
date", the second might be, some mechanical meters "last" 40 years.

I'm in no rush to get smart meter(s) unless they also agree to "tidy
up" the incomer and meter board and fit isolation switches. The
chances are a smart meter wouldn't have a comms signal anyway being
in the North and the Northern Network not using one of the mobile
networks but a system operated by Arqiva.
