If my kettle is 1500 w how do I work out if it’s cheaper to switch it on or boil same amount on gas?

For your comparison, consider that if you can put a single cup in the kettle and it takes 1 minute to boil then 1.5 / 60 = 0.025kWh, so less than 1p per boil @ 34p/kWh

Yep, target the things that use big amounts of energy such as heating and hot water rather than worrying about the kettle, which many seem to think uses a lot more energy than it does.They can use up to 3kW, which would be around £1 per hour, but they're only ever on for minutes rather than the hours that the heating and hot water are on for.2

Having a combi boiler means I can safely drink from the hot tap, so if I happening to be running the hot water to wash up or wash my dirty gardening hands & intend to then sit down with a cuppa I run hot water into the kettle then just bring it up to the boil when I'm ready to brew up. Or I suppose I could even run the hot tap into a flask for use a bit later for drinks or cooking. But even this Yorkshire tyke doesn't worry about every last penny, as long as I take good care of most of them.0

I was brought up not to drink water from the hot tap, that had been sitting in the copper tank, which was fed from the lidless zinc tank in the loft via the back boiler in the Aga. I will not drink from a hot tap unless I know it is a combi boiler.0 -

I, too, was brought up in circumstances where you tended to assume that the header tank for the hot-water system was an open tank, with all manner of life (and death!) in it and best avoided for drinking. However, my outlook changed when living in the tropics, where the cold water is often more risky than the hot water and I now have a daily fight against the muscle-memory that makes me reach for the hot tap when I want to brush my teeth.2 -
