Martin wrote : "Car insurance prices are on the rise - can you slash £100s off, even if not at renewal?
"The cheapest time to do a price comparison is 20 to 26 days before renewal (later and you're seen as a higher risk, pushing prices up)."
However, Martin said with prices rising, it's now worth checking even if you are midway through your policy.
He added: "You can usually get a refund for the rest of the year minus a £50ish admin fee, which may add up."
The only requirement is that you have not claimed during your current policy.
Martin recommends checking and combining as many comparison sites as you can.
Some of the best include MoneySupermarket, Confused, Compare The Marked and GoCompare, as well as ringing Direct Line.

One MoneySavingExpert said: "Renewed three weeks early after your tip. It's gone from a renewal price of £108 per month to £51 per month [saving £684/yr].
"Checked the comparisons later and it went back to £100. Happy."
