Grouping all your insurance together (car, household, homeowners etc) will normally get you a better rate
Increased
security measures will generally decrease your premium. N.B. If you
have been given a rate based on you having an alarm, then not
activating your alarm could cause problems with your claim
Staying with your insurer over time - being with one insurer for a long time and not claiming scores you points
Offer
to increase your excess payable on each claim - rather getting a
reduced premium. Some banks might restrict this though because if you
simply do not have the required exccess available at the time, you will
not get the repairs done - thereby reducing the value of their security.
Smoke
alarms will generally get you a discount. Everyone being non smokers
might also get a preferential nod, as many fires are caused by
cigarettes.
Geysers
are a big insurance expense. Installing Eldom instant geysers for
instance would reduce their risk and perhaps get you a reduced premium
Assess the price of rebuilding your home accurately and regularly so that you are not over insuring.
If
you are not using your fireplace, why not brick it up and just use as a
decorative feature - fireplaces add an additional hazard.
Lapa with a thatched roof attached to the house - maybe considering taking off the thatch when it ages and replace with tiles
Chat
to your broker - ask them what measures you can take to get your policy
reduced. Also remember to keep advising them of any changes to the home.
