Two contracts show the same omnium, the same insured value and a premium within a few euros of each other. One reimburses 750 euros of bodywork. The other pays you nothing, because the excess line of your policy schedule carries the word "anglaise" and 750 euros does not clear the threshold it sets.
The mechanism is nothing exotic in Belgium. It is heavily searched, too: according to Google Ads Keyword Planner volumes read in September 2026, the phrase franchise anglaise generates roughly 390 monthly searches in Belgium against about twenty in France. A Belgian contract clause, then, that the French pages saturating the results almost never explain.
What exactly is an English excess?
A threshold, not a subtraction. A classic excess is an amount deducted from the payout every time: a 1 500-euro claim with a 400-euro excess means the insurer transfers 1 100 euros. An English excess works on an all-or-nothing basis.
If the cost of the damage exceeds the threshold written in the contract, the insurer pays the lot, with nothing deducted. If it stays below, the insurer does not step in and you settle the whole invoice. The name comes from British policies, where this kind of threshold is long established, but the practice has taken firm root in Belgian omnium contracts.

Four clauses, one 750-euro claim
Nothing beats a single figure run through four different contracts. Take a vehicle insured for 20 000 euros excluding VAT, on a full omnium, and two claims: a knock costing 750 euros and a heavier impact at 2 000 euros.
| Clause written into the contract | Mechanism | You carry on a 750-euro claim | You carry on a 2 000-euro claim |
|---|---|---|---|
| Fixed excess of 600 euros | Deducted every time | 600 euros | 600 euros |
| English excess of 800 euros | Threshold, all or nothing | 750 euros | 0 euros |
| Proportional excess of 2.5% | Percentage of insured value, so 500 euros | 500 euros | 500 euros |
| No excess | No deduction | 0 euros | 0 euros |
Read the third column, then the fourth. On the small claim, the English excess is the worst of the four clauses: it leaves you with 750 euros to pay, more than the fixed excess. On the larger claim it becomes the best, level with having no excess at all, since the insurer pays everything without retention. No other clause in a motor contract flips this brutally depending on the size of the damage.
Why can a zero excess still cost you 750 euros?
Because "zero" and "nothing to pay" are not synonyms. Two very common commercial constructions sit behind that promise, and they do not have the same consequences.
The first is precisely the English excess: the contract announces no deduction, which is true, but makes any intervention conditional on clearing a threshold. The second is the waiver conditional on profile. At Ethias, the no-excess formula is aimed at policyholders who are 30 or over, in private use, and on condition that the repair is carried out at one of the company's approved garages. A driver of 27, or one who insists on the body shop round the corner, ends up on the formula with an excess, put at 450 euros in the example the insurer publishes.
The real figures of two Belgian contracts
Comparison sites are fond of ranges. Insurers' own terms give figures.
DVV publishes the grid for its Mobility motor contract, and that grid indexes the fixed excess on the insured value of the vehicle excluding VAT. Under 15 000 euros: 400 euros. From 15 000 to under 24 999 euros: 600 euros. From 24 999 euros upwards: 800 euros. The same company offers, as an option, an English excess triggered at 800 euros of damage, with the clearest wording on the Belgian market: above 800 euros, full compensation; below it, no intervention at all.
Two lessons follow, and both run against intuition. First, a fixed excess that tracks the value of the car means the most expensive vehicle carries the heaviest retained amount, even though its premium is already the highest. Second, on this particular contract the 800-euro English option sets the threshold above the fixed excess of the first two brackets. A driver whose car is worth 12 000 euros therefore swaps a certain 400-euro deduction for an 800-euro wall, which only makes sense if heavy impacts worry them and small ones do not.
DVV also specifies that, in its contract, the excess concerns only the material damage cover of the full omnium, neither the liability cover nor the mini-omnium. Material damage, in that wording, means damage you cause to your own car in an at-fault accident, or damage resulting from vandalism. The distinction matters more than it looks: a driver convinced they hold a no-excess policy may simply hold a policy whose covers never trigger one, which is a very different promise the day they run into a bollard. That logic recurs at several Belgian insurers without being universal: some contracts do apply an excess to theft, and glass cover almost always has a rule of its own. Our piece on glass cover sets out, for instance, a formula where the excess drops to zero at an approved repairer and rises to 250 euros anywhere else.
Is an English excess right for you?
The answer turns on a single question, and it is not a financial one: what kind of claim actually happens to you?
A driver who covers a lot of urban miles, parks on the street and racks up bumper scrapes has everything to lose from an 800-euro threshold. Those are exactly the claims that fall below it. A motorway driver who has not touched a door in ten years but fears leaving the road is better protected by an English excess than by a fixed one, since serious damage will be reimbursed without the slightest retention.
Should you raise your excess to lower your premium?
The lever exists and it works straight away, unlike the bonus-malus which demands a full claim-free year. Raising your excess means taking part of the risk back onto yourself, and the insurer passes that on to the premium.
The size of the discount, however, cannot be guessed. It varies by company, vehicle, region and driver profile, and no percentage holds for the Belgian market as a whole. The only reliable method is a costed trade-off: have the same contract quoted twice, once at the low excess, once at the high one, then compare the annual saving with the increase in what you would carry on a single claim. If the saving is 60 euros a year and the retained amount climbs by 400 euros, you need more than six at-fault-free years to break even.
A high excess only makes sense if you can advance it without strain on the day. Whether you can find 800 euros within the week weighs as much as the arithmetic.
Is there an excess on compulsory motor liability cover?
Not from the victim's point of view, and this is a Belgian rule worth knowing. Article 151 of the Act of 4 April 2014 makes exceptions, excesses, nullities and forfeitures unenforceable against the injured party in compulsory liability insurance contracts. The third party you hit is therefore compensated in full.
Your contract may still provide for an excess the insurer claims back from you afterwards, by way of recourse. It must have notified you of that intention, failing which it loses the right.
Five lines to look for in your policy schedule
Your general conditions explain the mechanism. Your policy schedule, the personal document, gives your figure. Where the two contradict each other, the schedule prevails. Open it and look for the following, in this order:
- The word qualifying the excess: fixed, English, proportional, or the phrase "intervention threshold", which means the same as English without naming it.
- The amount or the percentage, and the basis it is calculated on when it is a percentage: insured value, catalogue value, repair cost. Three bases, three different results.
- The covers concerned, one by one. An excess may exist on material damage and not on theft, or the reverse.
- The waiver conditions: minimum age, declared private use, repair at an approved garage, first claim of the year only.
- The doubling clause, common for drivers under 23 or 26 depending on the contract, and sometimes for undeclared occasional drivers.
That fifth point deserves close attention if you lend your car. Our article on lending your car in Belgium sets out the cases where the excess doubles without the lender having been warned.
Is an excess buy-back worth its price?
Almost every Belgian insurer sells an option removing or reducing the excess, against a premium loading or an annual flat fee. Some limit it to the first claim of the calendar year, which changes the equation a good deal.
The arithmetic is the same as the earlier trade-off, in reverse: compare the annual cost of the option with the excess it wipes out, then estimate how often you claim. An option costing 80 euros a year that removes a 600-euro excess pays for itself as soon as you report a claim every seven and a half years, an assumption on the optimistic side for a city driver and frankly pessimistic for a careful rural one. DVV offers an interesting variant with no premium loading: buying the excess back with points accumulated in its loyalty scheme.
Always ask for the exact scope of the option. Many buy-backs cover material damage and leave theft or glass under their own regime.
Does the excess affect your bonus-malus?
No, and that confusion costs those who make it dearly. Your level on the Belgian 0-to-22 scale moves according to at-fault claims that are reported and paid, never according to the money you take out of your own pocket.
An excess of 800 euros therefore buys you no protection against the malus. The only decision that protects your level is not to report minor damage and to settle it yourself, a trade-off we set out in our guide to the bonus-malus in Belgium. An English excess in fact makes that call simpler than elsewhere: below the threshold the insurer pays nothing anyway, so reporting serves no purpose. Above it, compensation is total and the malus question genuinely arises. Should you later disagree on how the clause was applied, a written complaint to the company followed by free recourse to the Insurance Ombudsman, the Belgian body handling consumer disputes with insurers, remain the two steps to take, and the handling of the claim itself falls outside the scope of this article.
Verdict: which excess clause suits your profile
To place each company on its formulas, its excess levels and its repairer network, our ranking of the best car insurers in Belgium is the starting point. Clauses that cost you an entire payout, rather than an excess, are covered in our file on forfeiture of cover, and the choice of formula itself in our comparison of mini-omnium and full omnium. The Wikifin portal, run by the FSMA, the Belgian financial services and markets authority, sets out the basic vocabulary of an insurance contract.
