Ellie Marsh

Ellie Marsh is the editorial byline used by the Watts & Bills cost desk. Articles published under this name are produced by our small editorial team with the help of AI drafting tools, and every dollar figure in them is calculated by our own published method from regulated reference prices - never estimated, and never copied from another site.

We use a single byline because the work is the same whoever types it: pull the current tariff, apply it to a real appliance rating, show the arithmetic. If you spot a number that looks wrong, we would genuinely like to hear about it - corrections go out the same week.

We are not electricians, energy brokers or financial advisers, we are not paid by any retailer, and we do not take commission for sending you to one. If you need a decision made about your own wiring, your own tank or your own contract, the person who should make it is a licensed tradesperson or your own retailer looking at your own bill.
