In the United Kingdom, Australia, New Zealand, and other Commonwealth jurisdictions, the term excess is the exact legal and operational equivalent of what North American insurers call a deductible. It represents the agreed sum you must contribute toward every claim.
Compulsory Excess vs. Voluntary Excess
In UK motor and home insurance policies, your total excess is composed of two distinct components added together:
| Excess Type | Who Sets It? | Can You Negotiate It? | Primary Purpose |
|---|---|---|---|
| Compulsory Excess | Fixed by the insurance underwriter | No (Mandatory baseline) | Reflects driver age, vehicle power category, or high-crime postcode. |
| Voluntary Excess | Chosen by the consumer at application | Yes (e.g. £0, £250, £500) | Higher voluntary excess yields lower monthly premiums. |
| Total Excess | Compulsory + Voluntary Added Together | Controlled by your voluntary selection | Total cash you must provide before claim settlement. |
If your car insurer imposes a £300 compulsory excess and you elected a £250 voluntary excess, your total excess is £550. If you suffer £2,500 of collision damage, you pay £550 and your insurer covers the remaining £1,950.
Can You Recover Your Excess After a Non-Fault Accident?
Yes. If another driver was 100% legally responsible for the crash and their insurer admits liability, you or your legal protection insurer can recover your excess payment directly from the at-fault driver's insurance carrier, as advised by UK MoneyHelper.
