Learning ways to cut down on energy bills has never been more important.

From leaving appliances on standby to using them too much, there are some household “offenders”, according to an expert.

Chris Madikian, an electrical expert at The Local Electrician, has shared the five “key offenders” which are likely causing the “most significant spikes in your energy bill”.

The pro has also shared tips for reducing their costly impact, helping households save money going into the New Year.

According to the expert, the top household offender is the washer-dryer, costing around £104.13 per year to run.

1. Washer-dryer

The expert explained: “These appliances account for approximately 12 percent of a typical energy bill, making them among the most energy-hungry in any household.

“The high usage of water and electricity required to heat it, combined with lengthy cycles, makes these appliances expensive to operate.

“Opt for cold-water washes, run full loads, use heated clothes airers and, if possible, air-dry clothes to significantly cut down on energy consumption.”

2. Tumble dryer

Essential for colder months, tumble dryers contribute around 11 percent to the typical energy bill due to the power required to dry clothes properly.

Try heated clothes airers or dehumidifiers as a tumble dryer could cost just shy of £100 per year to run.

3. Chest freezer

The expert said: “A chest freezer operates continuously and uses a significant amount of energy to maintain a steady temperature, accounting for eight percent of an average household’s energy expenditure.

“Regularly defrost your freezer, ensure door seals are intact, and maintain an optimal -18C for maximum efficiency.”

4. Fridge-freezer

A staple appliance that causes energy bills to spike is the fridge-freezer due to having to run it all the time.

It’s important to keep the fridge at 4C and avoid frequent door openings to maintain efficient operation.

5. Washing machine

An essential for any home, washing machines use substantial energy, particularly for hot-water cycles, and represent around seven percent of a home’s energy expenses.

To save money, wash at lower temperatures, use full loads and avoid pre-wash settings to cut down on energy costs.

The electrical pro noted: “As energy costs continue to rise, being aware of the most energy-intensive appliances in our homes, and knowing how to use them efficiently, can lead to substantial savings.

“By making small adjustments like washing clothes in cold water or adjusting fridge temperatures, homeowners can not only lower their bills but also reduce their environmental impact.

“It’s all about making smarter choices with the devices we rely on every day.”
