Reducing electricity use is often a combination of better habits, efficient equipment and keeping electrical systems in good condition.
Choose efficient lighting
Use appropriately rated LED lamps where suitable and switch lights off in unoccupied spaces. Match lamp wattage and fitting requirements.
Avoid unnecessary standby use
Switch off equipment that does not need to remain powered. Use quality power strips where appropriate, and do not overload extension boards.
Maintain your equipment
Damaged plugs, loose connections, hot sockets and flickering lights need attention. Repairs should be carried out by a qualified professional.
Efficiency matters, but never remove safety devices or improvise wiring to try to lower bills.
