In Australia we had the shilling meters were replaced with metered and billed systems from the early 1950s, for new buildings.
Boarding houses and similar could still get the coin-in-slot gas meters until well into the 1960s
But most of the new suburbs built from 1957 onwards were all-electric, to make full use of the newly opened Snowy mountains hydroelectric scheme
When they changed to meter-reading and billing, they did not change the meters in the old houses, unless they were leaking. All they did, around 1953, was take out the cash drawers.
No more running next door to change two sixpences into shillings, because your shilling would drop through to the bottom, then you could pick it up and put it back in again. Every 3 months the gas man would come and read the meter and you'd get a paper bill in the post.
We only had the stove and a fancy modern fake log fireplace that ran on gas. The copper and bath heater worked on kerosine, as gas was too expensive.
