Practical, independent, no gadgets to sell
Use less. Pay less. Without the hair shirt.
Electricity is 26.11p a unit and gas 7.33p under the current Ofgem cap, and most of your bill goes on a handful of things that make heat. Get those right and the rest barely matters. This is the plain version: what actually costs money, what is worth your time, and the tools to work out your own numbers.
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.
Calculators
Watts to kWh, cost of electricity, EV charging, solar payback, heat pump running cost and more. Free, instant, no sign-up.
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.
If you do one thing, do this
Chase the big users, not the small ones. Switching a phone charger off at the wall saves you pennies a year, so honestly, do not bother. Turning the thermostat down a degree or sealing your draughts saves real money, often £60 to £100. A lot of energy advice has it backwards, nagging you about the trivial while the tumble dryer and the electric shower quietly run up the bill. The cost calculator shows you which is which, in your own money, so you can stop guessing. That is the whole idea behind this site, and it is written by one person, Tom Fielding, who checks every figure against the Ofgem cap.
