INSURANCE companies charging the full fire services levy ahead of changes to the system in July have been put on notice.

Some property owners are furious they are being slugged the full amount now and will have to pay the levy again in a few months when it starts being charged through council rates, the Herald Sun reports.

The Baillieu Government introduced the switch from insurance policies to council collection after a recommendation from the bushfires royal commission.

City of Monash councillor Paul Klisaris said he was shocked his insurance company AAMI was not allowing a pro rata payment of the levy for his policy renewal for the period up to July.

"This is double-dipping," he said. "We deserve a refund because come July 1, property owners are going to be double-hit."

But AAMI spokesman Reuben Aitchison said that insurers were required to fund the fire services a specific dollar amount at the end of the financial year.

Households in outer suburbs and regional areas face a higher slug on their fire services levy than those in inner Melbourne.

"So it doesn't matter whether you take out your premium in July, January or May - the same proportion of that premium has to go towards calculating our obligations towards the fire services," Mr Aitchison said.
