I think you're right. People generally don't realise just how much effort was put in on the Home Front during WW2 to "keep the home fires burning" - the Land Girls and the Lumberjills were only recently recognised for their efforts in the general scheme of things, which is a bit mad considering that Britain suddenly had to produce more food and timber to make up for the lack of imports.
Then you had the people at the Ministry of Food making sure that everyone was fed and getting their fair share. The WI had a big role there, because much of the country's jam ration was made by the WI locally from donated fruit and then sent nationwide for distribution. Ration jam was made to a specific recipe which was 65% sugar to 35% fruit. You also had the ladies touring the country doing cookery demonstrations - Marguerite Patten spent the wartime years doing the MoF demos and writing leaflets and the like, although she was largely based in London.
And that's not taking into account the fire watchers and the ARP wardens and the people manning barrage balloons and ack-ack guns and the like. Then there's the fire brigade, who probably had one of the hardest and most dangerous domestic jobs during the war.
I actually find that the history of the Home Front is actually more fascinating than the military stuff - though that's interesting too
The best book on what actually happened on the Home Front during WW2 is probably:
“The People’s War” by Angus Calder. Very highly researched, but also readable.
