Martin Lewis has warned road users should be mindful of the day they renew their car insurance as they could save hundreds of pounds on their annual policies.

The Money Saving Expert founder has again stressed individuals should secure a new policy around three weeks before their current agreement is due to end.

Car insurance policies deal with “actuarial risk”, which is simply an assumption made by firms on how likely a particular individual is to claim on their agreement.

Securing quotes between 21 and 26 days before a renewal date will make road users seem less risk-averse and will often lead to the best prices.

Martin has previously issued the warning but provided a simple update to road users on his BBC show.

Speaking on the Martin Lewis Podcast, the finance guru said: “I often tell people you want to be getting quotes for your new insurance around 21 to 26 days before your current policy lapses.

“Why should that make a difference? Well, actuarially the type of people who get policy quotes at that time tend to be a lower risk than the people who leave it to the last minute.”

According to experts at MoneySuperMarket, renewing a policy between 20 to 30 days before its expiration is likely to pay off.

MoneySuperMarket added that renewing insurance any later than 20 days before a renewal is likely to see annual bills go up.

Drivers have previously admitted to saving hundreds of pounds off their annual bills using the simple tip.

One individual even dressed their quotes had gone from a staggering £1,500 per month to just £650 around 21 days before renewal.

However, individuals looking to secure the best possible prices should wait for exactly 23 days before an agreement ends.

Martin previously explained: “It starts to drop at around 30 days, you get into the sweet spot around three to four weeks before. It bottoms out at exactly 23 days – but, you know, let's not play that, this is averages – and then the price starts to rise and rise and rise and rise.

"So, for someone who here is paying around £700 if they get their insurance on the day of renewal, get a quote elsewhere, they're paying £1,200.

“So, what everybody needs to do is get in your diary that 23 days before renewal, because that's the actual sweet spot.”
