I have a Tesco Value kettle that i bought about 2 years ago for £5. It still works.
However, I am on a major money revamp and I wondered if I would save money switching to one to put on my gas hob.
Does anyone know? I have tried looking online but haven't found anything conclusive. I am sure gas is cheaper, but might take longer to boil? And with the whistling at least I wouldn't keep reboiling the kettle? I am quite good at only putting as much water as I need in it.
