I was in this situation 3 years ago, knocked off by third party, their assessor wrote the bike off as a Cat B, valued bike at £3000 and a salvage value of £116. Paid me £2884 and told me to dispose of bike, sold to a bike breakers for £650. Any cost for storage or recovery should be met by the third party insurers, keep receipts for everything, just remember that it is up to you to keep costs to a minimum, so any delay in disposing of the bike after they have said so, would be at your expense. Went through all this fiasco for the last three years, paid for the bike after 11 months, as a gesture of goodwill(!), then didn't settle the rest of the claim for a further 2 years. Worth it in the end, got £25,000!
