How to lower your energy bill — what actually works

There’s a mountain of energy-saving advice out there, and plenty of it saves pennies while feeling like a chore. Here’s what actually shifts the bill, roughly biggest lever first.

• Make sure you’re not already overpaying. The fastest “saving” isn’t using less — it’s a right-sized direct debit and the right tariff for your usage. Sort this first. Are you owed money? →
• Get on the cheapest tariff for your usage. Not the headline-cheapest — the one that fits how you actually use energy. How to find it →
• Hunt the always-on load. The background draw — old fridge, standby, that forgotten second freezer — runs 24/7 and quietly adds up. More on what drives a high bill →
• Heating is the big winter lever. For most homes it dwarfs everything else Oct–Mar. A degree or two on the thermostat, and heating only when you’re in, beats fiddling with phone chargers all day.
• Then the small, cheap stuff. LED bulbs, draught-proofing, a shorter shower — modest on their own, but free or near-free and they stack up.

The trick is doing the big levers first, in order — and that order depends on your home. Joulely works it out from your real usage, so you start where the money is.
