I am looking at this now for 2018 for a UK+Ireland trip where I will have at least 3 car hires of a about a week each time.
If you only have one hire then no biggie. But as you can buy an a 12 month policy with
www.icarhireinsurance.com which is only about the cost of one hire you end up a long way in front with multiple hires.
Plus the extra cover direct from the companies seems to be a lot higher than mentioned in this thread.
In addition it covers damage to bodywork, windscreens, tyres, roof and undercarriage that the car hire companies exclude.
