💡

Solar, batteries and heat pumps cut what you pay for energy. These cut how much you use in the first place, which matters whether or not you’ve installed any of them, and makes every one of those systems go further once you have.

No-cost changes

  1. Turn appliances off standby, not just off, TVs, consoles and set-top boxes on standby can add £50 to £80 a year combined.
  2. Wash clothes at 30°C instead of higher temperatures; most modern detergents are built for it and it can cut washing machine energy use by around 40%.
  3. Batch your dishwasher and washing machine loads rather than running half-full cycles.
  4. Turn your thermostat down by 1°C. It typically cuts heating bills by around 10% and is rarely noticeable.
  5. Close curtains at dusk to cut heat loss through windows overnight.
  6. Bleed your radiators once a year so they heat evenly without needing to run longer or hotter.
  7. Unplug chargers when not charging, small individually but it adds up across a household.

Low-cost changes

  1. Draught-proof doors and windows with strip seals, one of the cheapest fixes for heat loss, often paying for itself within a year.
  2. Switch to LED bulbs throughout the house if you haven’t already; they use about 80% less energy than old halogen bulbs.
  3. Fit a hot water cylinder jacket if you have a tank system, it’s a small cost with a fast payback in reduced standing heat loss.
  4. Use a smart plug or timer on always-on devices like router equipment that doesn’t need to run at full power overnight.
  5. Bulk up loft insulation if it’s below the recommended 270mm, often the single best-value insulation upgrade available.

Behaviour changes that cost nothing

  1. Shower instead of bath where practical, a bath uses roughly twice the hot water.
  2. Cook with lids on pans and match pan size to the hob ring, both cut cooking energy use.
  3. Track your actual usage through your smart meter app so you know which habits are worth changing rather than guessing.

Where this fits with solar

None of this replaces solar, a battery or a heat pump if your home suits them, but cutting baseline usage first means any system you install afterwards has to cover less demand, which improves its payback.
