Republic of Ireland car insurance

This potentially leaves Irish drivers paying more than they need to for car insurance because one of the major factors driving up prices is auto-renewal - when customers allow their insurer to automatically renew their policy, year after year.

You may have gone for a cheap deal when you first bought your car cover, but over the years insurers typically push premiums up for loyal customers, relying on consumer apathy to keep their business.

New customers are often offered discounts and deals that don't apply to existing customers, so it's worth shopping around every time you have to renew.

"The car insurance market is fiercely competitive and insurers often offer better deals to new customers than for those renewing existing policies," said GoCompare's Matt Oliver.

"So, our advice is simple - even if your current insurer offered the best deal last year, you shouldn't automatically assume that they will when your policy comes up for renewal.

"Use your renewal letter as a prompt to take action. Look at your renewal notice as soon as it arrives.

"Compare the price and cover against last year's documents, consider any changes you might need to make to the cover and take a look at similar policies with other insurers to see if you can make any savings.

"If you decide to switch, don't forget to notify your current provider. Most policies automatically renew, unless you tell the insurer otherwise within the 14-day cooling-off period.

"Miss the cut-off date and you could face hefty cancellation charges."

Other factors affecting car insurance prices in the Republic of Ireland

In addition to the auto-renewal trap and the lack of a fully developed price-comparison market, there are a variety of other factors that could prevent drivers from getting cheap car insurance in the Republic of Ireland.

Much of the motoring in the country is on rural roads and/or single carriageways, and these types of routes can lead to high incidences of accidents and expensive claims.

In addition there are price-inflating factors that will be familiar to drivers in the UK and elsewhere, including whiplash and other personal injury claims, plus vehicle crime and fraud such as crash-for-cash scams.

Women's car insurance in the Republic of Ireland

Women in the Republic of Ireland used to be able to secure cheaper car insurance deals than men, based on statistics proving that they're the safer drivers. That changed in 2012, when the European Court of Justice (ECJ) gender ruling made it illegal to charge a different price for insurance based on gender.

Female drivers should consider, though, that their safer driving record does make many insurers keen to get them onto their books.

Research from Newcastle University Business School has suggested that some insurers may weight the importance of a job title in favour of female-friendly professions.

Your job is one of the many factors that insurers will take into account when calculating your premium and each company will have its own way of assessing a particular occupation - read more in our article on how your job affects your car insurance.

What's more, insurers may produce advertising intended to appeal to women and offer added extras which they believe females will find appealing, things such as priority breakdown cover and (however patronising some may consider this!) handbag cover.

Another option for female drivers to think about may be telematics; this uses a mobile phone app or a 'black box' in your car to base the price you pay for cover on the way you actually drive.

Given that women are statistically the safer, better drivers, it follows that they may potentially have more to gain from telematics than men.

Crossing from the Republic of Ireland to Northern Ireland

The border between the Republic of Ireland and Northern Ireland may barely register when you cross it and there's no passport check to go through.

But you should check your policy to see whether your insurer covers you for both countries - it's possible that it may treat Northern Ireland like any other EU country, which would mean that you'd need to have European cover and that you may have to inform your insurer of your cross-border trip.

There are numerous vehicle-carrying ferries operating into and out of the Republic of Ireland and, if you plan to use one, it's again advisable to check your car insurance terms and conditions.

While you should expect some sort of cover, not all insurers will have the same conditions.

If, for example, you have a comprehensive policy your insurance protection on a ferry may not be as extensive as it is on a Republic of Ireland road.

It's also worth checking your breakdown cover in advance. Should your motor conk out on the wrong side of the Irish Sea, not all breakdown providers will cover the cost of the ferry transportation back, even if your policy has nationwide recovery included on it.
