Energy advice
- Electric showers: Take shorter, cooler showers to reduce electricity use.
- Immersion heater: Set a timer to heat water only when needed. Don’t leave it on.
- Bathroom lighting: Bathrooms often have multiple lights. If possible, replace old bulbs with energy-efficient LEDs.
- Extractor fans: Help prevent dampness but can waste energy if left running too long.
