Practical, independent, no gadgets to sell
Use less. Pay less. Without the hair shirt.
Most household energy is spent in a handful of places, and most of the savings come from a handful of changes. This is a plain guide to which ones are worth the bother, backed by tools to work out what things actually cost you.
Electricity
The biggest users in the home, standby waste, lighting, and the quick wins that move the meter.
Heating & gas
Usually the largest bill of all. Thermostats, draughts, insulation and getting more from the boiler.
Fuel & driving
How driving style, tyres and a few habits change what you spend at the pump.
Cost calculator
Enter an appliance's watts and how long it runs, and see the cost per use, per day and per year.
Guides
Single-topic, practical guides that go a level deeper than the section pages.
About
Why this exists, and the one rule behind every page: spend effort where the energy actually goes.
The one idea worth keeping
If you take a single thing from this site, take this: chase the big users, not the small ones. Switching off a phone charger saves pennies a year, while turning the thermostat down by a degree or fixing draughts saves real money. A surprising amount of energy advice has you fussing over the trivial while the expensive stuff runs on unquestioned. The cost calculator exists to show you which is which, in your own money.
