Do I Pay My Excess After a Non-Fault Accident? The Straight Answer

The excess feels unfair after a non-fault accident precisely because it has nothing to do with fault. It is simply the first part of any claim on your own policy that you agreed to fund yourself when you bought the insurance. Your insurer applies it mechanically: whatever the repair costs, your contribution comes off the top, whoever caused the damage. Paying an excess upfront on an own-policy claim, even when you were plainly not at fault, is normal UK practice, not a sign your insurer is treating you badly.

What fault does decide is where the money ends up. When the other driver caused the collision, your insurer pursues their insurer for its outlay on the claim, and your excess rides along with that recovery. The upfront payment is a cash-flow problem rather than a permanent loss, provided liability lands where it should. That distinction matters, because the two things drivers mix up most are paying the excess, which is about your policy terms, and keeping the excess, which is about liability.

Your excess is what the industry calls an uninsured loss: a cost the accident caused you that your own policy does not cover. Other uninsured losses include things like a hire car you paid for yourself, damaged personal belongings, or lost earnings. When the accident was not your fault, these losses are claimed from the at-fault driver's insurer, either by your own insurer's uninsured loss recovery service, a legal expenses add-on if your policy has one, or an independent claims company acting for you.

The refund follows successful recovery. Once the at-fault insurer accepts liability and reimburses your insurer's outlay, the excess comes back to you. If the recovery stalls, the refund stalls with it, which is why the timescale is genuinely variable: a claim where liability is admitted in days behaves very differently from one where the other driver disputes everything. Some insurers will waive the excess on an obviously non-fault claim as a goodwill decision, and it is worth asking, but it remains their discretion rather than your entitlement.

The excess only exists inside your own policy, so the way to avoid it is to keep your own policy out of the claim. After a non-fault accident you can claim directly against the at-fault driver's insurer instead, usually through an accident management company that handles the repairs, a replacement vehicle and the negotiation on your behalf. Because your own insurer never funds anything, there is no excess to pay, nothing to wait to be refunded, and no claim running through your own policy while the insurers argue.

The honest condition is the same one that applies to every non-fault arrangement: this route works when the other driver is clearly at fault, because the costs are recovered from their insurer. If liability is disputed, the position changes, and you should be told that before anything is arranged, not billed for it afterwards. That is how CityGrip Accident Claims works: the liability picture is assessed first, and the direct route is only recommended when the evidence actually supports it.

Not every claim ends with liability sitting entirely on one driver. Where fault is shared, a claim may settle on a split basis, fifty-fifty or some other proportion, and the recovery of your losses is reduced to match. On a fifty-fifty settlement, only half of your insurer's outlay is recovered, and in practice part of your excess may not come back at all. Split liability is common in roundabout collisions, lane-merge disputes and car park incidents where the evidence points both ways. Motorway lane-change collisions can go the same way when there is no footage.

This is another reason the evidence you gather at the scene has a direct cash value. Photographs of the vehicles and their positions, witness details and dashcam footage are frequently what turns an argument about shared blame into an accepted non-fault claim, and with it a full excess refund rather than a partial one. It is also why any company that promises every driver a guaranteed refund, before liability has even been looked at, should be treated with caution. The honest position is that the outcome follows the evidence.

If liability is genuinely clear, the direct route against the at-fault insurer usually leaves you better off in the short term: no excess to fund, a like-for-like replacement vehicle arranged on a credit hire basis, and your own policy left untouched. If liability is uncertain, claiming through your own insurer, paying the excess and pursuing it as an uninsured loss can be the more sensible path, because your policy responds regardless of who was at fault while the argument is settled.

The decision is easier to make with someone who sees both routes every week. Because our group handles the recovery and, through CityGrip Accident Claims, the claim itself, the assessment happens early: how strong the liability evidence is, whether the direct route is safe, and what each option means for your excess. You get a recommendation based on your accident rather than a script, and if the answer is that you will need to pay your excess and claim it back, you are told that plainly at the start.
