Overview
- Lewis urges households to use “tactical” curtains, opening in daylight and closing by about 6pm to retain heat, with budget fleece linings only if they meet fire-safety standards.
- Dropping the room thermostat by one degree can trim heating costs, with the Energy Saving Trust estimating savings of about £90 a year for an average home.
- The Nesta-run Boiler Challenge encourages combi-boiler users to lower flow temperature to around 60°C, a quick front-panel adjustment that Lewis says can save roughly £100 annually.
- For non‑combi boilers, outlets note that changing flow temperature may require professional help to ensure safe and efficient operation.
- Save Water Save Money lists around 900,000 free water‑saving devices, and Lewis says an air‑mixing shower head could cut about £50 a year for frequent shower users; he also advises setting fridges to 5°C and freezers to −18°C to avoid waste.
