Start by reviewing recent bills and meter readings, then check whether your current plan still suits your usage and compare available options with your provider. Simple changes such as using heating controls, reducing draughts, washing at lower temperatures and avoiding standby use may reduce consumption, although the saving will depend on your home and habits. Consider moving a realistic estimate of any reduction into a separate savings account after each payday, while keeping essential heating and comfort in mind.
