The sequence of events is that local "town" gas works existed, which were taken into the control of local authorities. These local works were nationalized in 1948 into regional gas boards. This state continued to exist on after the introduction of North Sea gas. In order to privatize the gas industry, the then government had to combine these boards into a country wide monopoly in order to privatise it as British gas.
But the reality is that for gas, as for water and electric, they are natural monopolies, whether local, regional or national.
There is only one gas pipe running to my house, only one water, only one electric line.
That infrastructure level is naturally a monopoly, there is no consumer choice, as distinguished from the companies supplying gas/water/electricity through that infrastructure.
If you take the Electricity industry as an example, it is split between the following players:
Electricity Suppliers - buy electricity from the generators, and sell it to customers, pay the middlemen to transport it. Competitive market, so of these have gone bust recently.
Electricity Generators - sell to the Suppliers, competitive market
National Grid - Connect generators to distribution operators in England and Wales. Scotland grid run separately by SSE. Also manage interconnectors to France etc. Natural monopoly, highly regulated
System Operation - Matching supply and demand, was part of NG, but being separated out under public control.
Distribution Network Operators - 14 regional companies who run the substations and wires down the street. Charge the suppliers for transporting the electricity. Natural monopolies, highly regulated.
Picture is further complicated by the fact that companies opeate in more than one part of the market. E.g. SSE run the grid in Scotland, are a significant generator (big investment in renewables) are a DNO in some regions (4?), but have now exited the Electricity supply business.
Viewing these industries in entirety as "natural monopolies" can be overly simplistic, and a little misleading
