The huge rise in whiplash claims is directly linked to huge rise in ambulance chasing parasites that now seem to plague us every step of the way. Whilst these charlatans are allowed to practise, premiums will continue to rise. Incidently, it's not just whiplash claims that are the cause of rising premiums, but taking that as an example, a solicitor will claim up to £1000 to process an electronic claim for whiplash where the victim will get £700. After that, say the facts are disputed, that same solicitor will then pick up another £500 - £1000, so your £700 whiplash claim is actually costing the insurers a minimum of £1700.
And there are of course, those less than scrupulous insurance companies, whose practises are borderline legal, but again put the costs of what should be a straighforward claim, through the roof.
