City of Sydney council has taken the first steps to ban gas for all new homes and businesses.

It comes after a motion was passed on Monday night, with eight out of 10 councillors voting to 'investigate' the opportunities and challenges of a ban on gas connections.

The move will introduce clauses to developing rules which require new homes and businesses within the council area to be all-electric and gas-free.

It would require installing only electric appliances including stoves, cooktops, heaters and hot water units.

The City of Sydney became the latest council to start the process of banning gas, despite NSW Premier Chris Minns ruling out a statewide ban last month.

Clover Moore's City of Sydney council passed a motion on Monday night banning gas connections in new homes and businesses, with eight out of 10 councillors voting in support of the ban

Lord Mayor Clover Moore and Greens Councillor Sylvie Ellsmore pushed the ban, with council papers claiming the ban on gas is 'based on the health, economic and environmental benefits that all-electric buildings produce for future occupants'.

The council takes in Sydney's central business district and surrounding inner-city suburbs, covering a resident population of more than 210,000 people.

City of Sydney Council also wants to force homes and businesses to get rid of their already existing gas in favour of electric connections.

Council papers urged staff to consider 'any other potential amendments that would facilitate or speed up the transition of existing resident and non-residential buildings in the City of Sydney to become all-electric and gas-free'.

Premier Chris Minns previously ruled out banning new gas connections in NSW, saying it would complicate the 'extreme' challenges the state faced in its transition to renewable energy.

Local councils in Sydney are deciding to overrule State Premier Chris Minns, with Waverley in Sydney's east and Canterbury-Bankstown in the south west establishing rules that require new buildings to have electric appliances only.

Parramatta council also banned new gas connections in the city's CBD, according to the City of Sydney's council papers.

Randwick Council will be voting on a motion to implement a statewide ban on Tuesday.

Under the 1979 EPA Act, councils have the power to implement their own bans by imposing restrictive conditions on development applications and plans.

However, the state government has the power to override local councils by implementing planning rules, with opposition calling on Premier Minns to stop councils from imposing 'different rules across the state'.

Liberal Councillor at Randwick Council Christie Hamilton told 2GB host Ben Fordham on Tuesday the plan to ban gas is 'nonsense'.

'I think it's nonsense, it's so out of touch with the cost of living pressures that everyone is feeling right now,' Ms Hamilton said.

'This motion says that electricity is cheaper to run meaning lower energy bills. That's just not true.

'We don't have an alternative to turn off gas for an equally priced alternative. If we did, we could do it, but we don't.'

Liberal Councillor at Randwick Council Christie Hamilton said the ban on gas was 'nonsense' and urged Premier Chris Minns to consider NSW residents struggling with the cost of living

Ms Hamilton, who has been on Randwick Council since 2017, said the issue with gas has 'bubbled' away in the background but will come to the forefront during council's meeting.

Randwick Councillors will not be voting to ban gas on new developments or to introduce the planning control measures in Randwick council.

Rather, councilors will vote to send through a motion to the local government NSW annual conference to call on the state government to ban gas across the entire state.

Ms Hamilton said she will be arguing against the motion as it affects all Australians.

'I will be arguing against this [motion], I find it to be very dismissive of Randwick residents, rate payers and renters, this affects everybody,' Ms Hamilton said.

She urged Premier Chris Minns to consider NSW residents struggling with the cost of living.

'Chris Minns needs to consider what he needs to do for NSW residents and I believe considering how costly it is to live right now, how bills are already going through the roof, this is not something we should do right now,' Ms Hamilton said.

'We don't have an alternative to turn of gas for an equally priced alternative. If we did, we could do it but we don't.'

Celebrity chef Luke Mangan told Ben Fordham the kitchen for his new restaurant, which is located in Potts Point, was being delivered on Tuesday is all gas and valued at about $400,000.

Mr Mangan said cooking with gas was quicker, easier and more efficient in a commercial space and claimed the ban on gas would be detrimental to small businesses.

'Seriously if we think of all of these small businesses around the state and around the country with cafes and wine bars and restaurants, what if they've put these gas cooktops in 6-12 months ago,' He said.

'Small businesses are under the pump already with interest rates going up, people not spending… now electricity, gas, your wages, everything has gone up and produce has gone up.

'These businesses can't keep putting prices up to stay in business because people just don't want to spend more at this period.'

He also questioned how the ban would effect existing homes and their barbeques.

'What about the barbie out the back that's connected to gas, do we rip that out and have to have an electric barbie?,' Mr Mangan said.

'The small Aussie hardworking battlers at home cannot rip out a gas stove and put in an electric stove because the bloody government says so.'

The celebrity chef also offered to take Premier Chris Minns on a tour of small businesses to show him how the ban will affect struggling restaurants.

On July 28, Daniel Andrews' Labor government banned new homes from connecting to natural gas, in a bid for Victoria to halve carbon emissions by 2030.

Energy Minister Lily D'Ambrosio and Planning Minister Sonya Kilkenny announced the changes to energy supply, with the policy set to to kick in on January 1, 2024.

In addition to residential housing, any new public buildings which are yet to reach design stages by the cut off date - including schools, police stations and hospitals - must be entirely electric.
