My house sits right on the border between 2 suburbs, as in, the front door is in Suburb A and the back door is in Suburb B. We are under the local council for Suburb A and pay our rates to them, but Suburb B is under a different local council despite having the same postcode. (It was quite funny during lockdown as Suburb B was under a very strict, not allowed to leave your house, restriction while Suburb A could move around freely so we joked that we couldn't go into our back garden at all but we could head out the front quite freely.) Both suburbs having the same postcode means that sometimes when I order online I get asked if its '123 Streetname, Suburb A or 123 Streetname, Suburb B. It's the exact same location, same house, just listed differently in some places.
So here is my issue - we have recently changed insurers and when we provided our address as Suburb A (as that is where we pay rates) they said they couldn't accept that as the deeds for the house listed it as being in Suburb B so we had to change the address to Suburb B on the insurance documents. Since changing the suburb the insurance have come back and said that our payments will be $10 per month more than originally quoted as we are now living in Suburb B.
We haven't moved, the house is where it has always been. Would you challenge the insurer on this and request they honour their original price?
