Why this site exists
Ask a simple question about your home — how much does a dehumidifier cost to run, is it cheaper to leave the heating on low, is loft insulation actually worth it — and you get one of two answers. Either a vague article that never gives you a number, or a comparison site that wants you to switch supplier before it will tell you anything.
WarmerBills exists to give you the number.
Every article on this site starts with a figure. Not “it depends on your usage” — an actual cost in pounds, with the calculation shown underneath so you can check it against your own bill.
What we cover
Six areas, all focused on what a UK home actually costs to run:
- Running costs — what individual appliances add to your electricity bill
- Heating and boilers — thermostats, radiators, boiler problems and replacement
- Insulation and damp — loft, cavity, draughts, condensation and mould
- Solar and home batteries — realistic payback figures, not sales pitches
- Energy bills and tariffs — standing charges, meters, how your bill is built
- EV charging at home — installation costs and what charging actually adds
How we work out the figures
Every running-cost calculation on this site uses the same method: appliance wattage, realistic hours of use, and a stated unit rate. We show all three in a table on every article so you can substitute your own numbers.
We review our unit rate assumption every quarter and update the figures across the site when energy prices change. The date of the last update appears at the top of every article.
We are not energy consultants, engineers or financial advisers. We are researchers who read manufacturer specifications, government publications and our own bills, then do the arithmetic and present it clearly. Where a question needs a qualified professional — gas work, electrical installation, structural damp — we say so and tell you to get one.
Who writes this
WarmerBills is written and edited by Edward Cox, working from published manufacturer data, Ofgem figures, government energy statistics and real household bills.
Edward is a writer and researcher, not a tradesperson. That shapes what this site does and does not do. We are good at working out what things cost and explaining it plainly. We do not give installation instructions for work that legally requires a registered engineer, and we will always tell you when you need one.
What we will not do
- We will not tell you something is worth buying when the numbers say it is not. Several articles on this site conclude that a popular product does not pay for itself.
- We will not publish a figure we cannot show the working for.
- We will not let a sponsor change a conclusion. See our Editorial Policy for how commercial content is handled.
