How much compensation for whiplash?

Really the amount of compensation that is received for whiplash depends mainly on the severity of the whiplash injury itself.
If the injury is set to last for longer than 12 months then for obvious reasons the amount of compensation will likely be significantly higher than if you would recover within six months.

The usual scale for whiplash injury compensation is as follows

Injuries to the Neck

Minor (Whiplash) £1,000 - £7,000
Moderate (Whiplash) £3,500 - £25,000
Severe (Fractures to the neck) £12,000 - £250,000

It is not uncommon for sufferers of whiplash to receive compensation in the region of 10,000 GBP.
There have even been people who have taken home 30,000 GBP.
No one who is a sufferer of whiplash neck injury should suffer in silence, where there is blame there is a claim and it is always worth making an inquiry because it costs you nothing, and is usually conducted on a no win no fee basis.
