Thanks everyone for all your comments, I can see it is a common problem. And I agree petitpois the washing machine is just as bad. Surely with all our scientific knowledge nowadays making quieter appliances can't be rocket science!!
What you need is one with an old-style coiled element in, but I don't think there are any anymore. The new ones amplify the noise because the flat bottom acts like a drum skin.
"You could boil water in the microwave though"
Very dangerous. The water can become super-heated, and then boil explosively in your face when you touch it with a teaspoon.
They are all noisy these days. We went on a quest a couple of years ago to find a quiet one, but they all seem to have this 'rapid boil' system which makes them noisier than of yore. I can't honestly say I've noticed them boiling any more rapidly than they used to, tbh
I am fed up having to raise my voice and /or turn up the radio while my kettle is boiling. Does anyone know of a make of kettle which is 'quiet' while boiling.
