It’s not, a kettle puts in almost all the energy into the water. A pan you lose loads to the air between the heat source and the pan.

Plus the heating of the pan itself is inefficient

But surely more than 50% (total)? Just using that figure as the difference between gas and electric costs.

Kettle is fine to boil water with, just don't overfill the kettle and it will remain reasonably efficient.

This is the kettle we have. You can choose the temperature and there's a level viewing facility with notches to tell when you've filled just what you need.

Be careful with that as smart plugs aren't really designed for 3Kw loads.

Yeah, I have the earlier version. Great kettle. Boils quickly. tbh, I rarely use it for heating water to anything less than boiling unless I'm descaling it, in which scenario, that and the keep warm function really works. I think we've had ours for about 10 years.
It happily boils 1 cup of water. It'll boil less than that. As with most modern kettles, the bottom of the kettle is the element so as long as that remains covered, it'll boil without tripping.
Descaling is the most important thing in keeping kettle costs down I think. Something that Boris forgot to mention. "If you've got an old kettle that takes ages to boil", descale it. I doubt he knows what that even means though.
A clean kettle will boil water much faster, use less electricity in doing so and if kept clean will last a **** load longer.
1.65L's of water boiled in my rarely used kettle is ~141Wh, from a tap water temperature of between 15-17c, a single 250ml measurement is 35Wh. Where as using the water boiler to do a single cup of 250ml is ~30Wh, from the same tap temperature, which means it is more efficient to use a kettle when needing a larger amount of boiling water.
Unusually it maybe that my kettle is very poor/inefficient at lower volumes, but I have completed the measurement several times, and find the same result. The secondary benefit of the water boiler is the fact the ambient temperature of the water becomes warmer after it is filled, meaning the second/third cups use less energy throughout the day, especially in the winter when the tap temps are quite a bit lower.
I can/will do measurements of 70/80/90c with the water boiler to see the results, but I have loaned out my power meter to a family member so they can find their devices using power all-day.

I only use the temperature setting if I'm "re-boiling" as I'll select 90C instead of 100. We also don't need to bother with descaling as I live in a Scotland.
The main thing is to boil only what you need; that's as frugal as we need to be with kettles IMO
Yeah it is. Using a kettle is the most efficient way to boil water but not the cheapest due to the difference in unit cost of energy. Dunno what it is now, but a quick look at my last bill has Gas at 7.4p/kWh vs Electricity at 27p/kwh. Electricity is more efficient but unit cost for energy is almost X4. Maybe we should harness the hot air that comes out of Boris's gob and save the country??
I suppose it's not too late to install a gas hob, unless you have a battery that can help out.
seems the eu is proposing an efficiency rating for electric kettles, also telling you what their minimum quantity of water is
so barely worthwhile boiling a kettle for cooking/steaming vegetables with an induction hob

Is the microwave for the Americans, that's how they boil water isn't it

.Found this, so maybe hope for those of us in rentals.I suppose it's not too late to install a gas hob, unless you have a battery that can help out.

Thought I'd been doing well with this.
Got down to 2 kettle boils a day using my flasks.
However the 2 year old got a sickness bug and it's rained solid... So my tumble drier use has gone silly!
I've also got one of those smart plugs with an energy monitor in. Going round each room and looking for energy sappers.

Replaced the old 5ft strip light bulb in the kitchen for an led one. Not cheap but nice to see the ihd only going up a few watts when it's turned on, and instant light!
That was the last bulb to be changed, all led now. New kettle as well with variable temps. With that and another layer of loft insulation last week there's not much more we can do really without spending out for heat pump dryers etc..

what brand then - do you get one with a 2? 5? year warranty
I'm tired of my mid price V-tac ones blowing, so trying to get a warranty & buy directly from amazon/reputed-shop.
If you are boiling what you need , do you need to be cautionary about left-overs.
ok good warranty - I'm a 4000K lover (all neigbours in the gloom of 2.7) , or did you go 6K -
I had tried some 6K cree bulbs in previous kitchen, first leds I'd ever bought, and could no longer see the gas flames clearly,
(following earlier post, currently waiting for amazon to deliver a high cri 6K bulb for tv bias lighting to see if main living room bulb could be turned off when tv on)
Respect. All my bulbs are 4000K.
6000k for the kitchen, it's a big room with some gloomy corners. Will see how long it lasts but am already liking not having to wait for the bulb to light up!

Its lumens you want for lighting bright corners as opposed to the K value (which is colour temperature and not the "brightness")
