As restrictions ease, many are left wondering what the financial impact of working, living and schooling from home, for a prolonged period, will have on their pocket.

A spokesman for The Salvation Army said while they hadn't particularly seen an increase in requests for help with energy bills yet, they are predicting an increase in the future.

"This is because we feel like people are getting more payment deferrals from their energy providers due to COVID-19," the spokesman said.

"However, those bills will then accrue and need to be paid eventually, which may have more negative effects in the long-term."

The Salvos financial counselling service Moneycare, which provides a free and confidential financial counselling service, regularly works with people who have unmanageable energy bills.

"Prior to Covid-19 the people coming to us on average spent 15 per cent of their income on energy, mainly because it is largely an unavoidable cost," the spokesperson said.

"The average Australian household spends 2-3 per cent of their income on energy, and the amount owed to electricity companies has increased by 18 per cent over the last five years.

"We are very concerned that this year's winter bills will be even more unmanageable for people who are now, or have been, staying home and using more energy."

A spokesman for the Australian Energy Council said that it's too early to know the full impact of COVID-19 on retail customers and energy businesses.

"Retailers are seeing an increase in customers seeking support and the market regulator has reported that since March 20,000 customers nationally have registered for payment plans," the council spokesperson said.

"The extent of the impact on households' energy use from working from home will vary, but there is likely to be increased pressure on energy consumption with the colder weather.

"There is a range of assistance available and retailers are ready to help.

"The assistance may vary based on each customer's individual circumstances but can include things like payment plans, bill smoothing, assistance in accessing grants and concessions, as well as hardship programs."

The spokesman said customers who have concerns about being able to manage their household bills can contact their energy retailer.

"At the same time, this crisis will also continue to put increased pressure on retailers and we welcome recent moves by regulators in recognition that the viability of energy businesses is critical at this time."
