Energy specialists warn against common household mistakes, as fuel bills remain a concern

With winter just around the corner, many households are looking for ways to cut their energy bills.

However, it turns out that some of the most popular advice about saving energy at home is actually wrong.


Energy specialists at Your NRG, Britain's leading independent fuel distributor, have identified five widespread misconceptions that could be costing people money rather than saving it.

Gordon Wallis, an energy expert with the company, points out that these myths persist despite being ineffective.

"By understanding what actually works and putting these steps in place in September, you can avoid wasted energy and ensure your home runs more efficiently when the heating season begins," Mr Wallis explained.

Here are the five myths they say households should avoid:

1. Leaving heating on low all day saves money

"This is not true for most households," says Mr Wallis.

He explains that warmth continuously escapes and needs replacing, meaning energy is wasted. Instead, heat your home only when you need it.

2. Portable heaters are cheaper than central heating

While useful for heating one small space, experts say they often cost more per unit of heat than a boiler.

They should only be used for short periods or in rooms without central heating.

3. Turning the thermostat higher warms the home faster

Heating systems work at the same rate, regardless of the thermostat setting.

A higher setting just keeps the boiler running longer, leading to overheated rooms and bigger bills.

4. Closing vents in unused rooms saves energy

Shutting vents in central heating systems creates imbalances that reduce efficiency.

A better option is to lower the temperature in rooms not being used, instead of blocking airflow.


5. Windows don’t make much difference to heat loss

Poorly sealed or single-glazed windows are a major source of wasted heat.

Simple fixes like draught-proofing strips or thermal curtains can cut down losses significantly.

With energy costs remaining high, experts stress that households should focus on proven strategies rather than myths.

Implementing these steps in September gives families the best chance of saving money before the cold weather sets in.

Many households remain confused by conflicting advice, making clear information essential.

Energy experts stress that even small changes, such as sealing draughts or adjusting thermostat use, can add up to noticeable savings.

LATEST DEVELOPMENTS:

Government data shows that heating accounts for more than half of the average household energy bill.

This means improvements in efficiency directly translate into reduced costs for families.

Industry figures suggest that British households could save hundreds of pounds a year by avoiding common mistakes.

Clear, practical steps remain the most effective way to keep homes both warm and affordable this winter.
