Yes. The excess you pay depends on the type and value of the claim.
Claim amount is under £1,500 = excess of £50
Claim amount is £1,500 to £2,999 = excess of £100
Claim amount is £3,000 to £4,999 = excess of £150
Claim amount is over £5,000 = excess of £200
For all public liability claims, you must pay the first £500 of each claim arising from damage to third party property.
