AG Insurance or KBC: which car insurance to choose?

AG Insurance and KBC target the same experienced driver, but they do not play on the same field. AG publishes a deductible (franchise) grid reserved for good profiles. KBC locks in its price, identical online and in branch. For a driver aged 40 to 55 with no claims, the difference shows in the deductible, not in the headline premium.

AG Insurance or KBC: which one for an experienced driver?

AG Insurance, if your bonus-malus is low. It is the only one of the two to reserve a deductible cut to €0 for drivers rated between −2 and 0 on the Belgian 0–22 no-claims scale. KBC, if you want a locked-in price and long total-loss cover: same price online and in branch, purchase price refunded for up to 48 months.

This contrast is anything but theoretical. A 45-year-old driver, licensed for twenty years, with no at-fault claims, sits exactly in the zone where AG unlocks its most favourable terms: bonus-malus between −2 and 0 for the Franchise Flexi, and bonus-malus between −2 and 8, age between 26 and 75, at most one at-fault claim over five years for the reduced deductibles. These are the conditions written in black and white in AG Insurance's Top Omnium product sheet.

In practice, this profile pays at AG a deductible that drops to zero as soon as a third party is identified, or in the event of a hit-and-run or vandalism if the complaint reaches the police within 24 hours. At KBC, the deductible you choose applies whatever happens for material damage. The logic is reversed: AG rewards a clean record with a conditional deductible, KBC sells a fixed, predictable deductible.

A word on the vocabulary, because it is misused everywhere: the deductible is the share of the loss that stays with you after a covered claim. It does not change the scope of the cover, only who pays the first few hundred euros. Not to be confused with the taper, which reduces the payout in the event of total loss as the car gets older.

How do AG Insurance and KBC deductibles compare?

AG is more granular, KBC simpler. AG publishes three deductible tiers based on the value of the vehicle and two mechanisms to choose from; KBC advertises a single range of €250 to €1,250 that you set to match your budget.

At AG, the basic deductible for material damage is €250 for a vehicle up to €20,000 excluding VAT, €400 between €20,000 and €30,000, €700 above that. You can move up a tier to save 10% of premium, or move down by paying 10 to 40% more premium. Under multirisques (the small omnium: theft, fire, broken glass, hail, storm, collision with an animal), AG applies no deductible.

At KBC, the partial omnium also works with no deductible, with one precise exception: a windscreen repair carried out outside the network of approved glass repairers. If you go through the KBC list, the insurer settles the bill directly with the repairer and you pay nothing.

Is it worth paying more for a lower deductible?

Rarely, for this profile. Moving from a fixed €700 deductible to €400 at AG costs 10% more premium, every year. On a €900/year omnium, that is €90 a year to save €300 on the day of an at-fault claim. An experienced driver who reports an at-fault claim every eight years loses out. The trade-off flips if you drive in a dense city or if your car sleeps on the street.

What does each contract cover in the event of total loss or theft?

KBC holds out longer, AG protects more strongly at the start. KBC refunds the full purchase price for up to 48 months for a new car or a used car less than 3 years old, and 24 months for an older used car. AG guarantees a payout with no loss of value during the first 6 months and the first 10,000 kilometres.

After the as-new value period, AG applies a taper of 1% per month from the 7th month with the Excellence formula, against 1.25% from the first month with the cheaper Classic formula. KBC plays another card: the "10% extra" option, which increases the payout by 10% in the event of theft or total loss, with no proof of use required. The insurer writes that more than four clients out of five take it and that after five years it still leaves 77% of the purchase price.

What few people know: at KBC, in the event of total loss or theft, you are not required to buy the same model or the same brand again. You can even decide not to buy another car at all and keep the payout. Not every company writes that as clearly.

What discounts can you really get?

AG advertises two quantified discounts, KBC bets on channel neutrality. AG grants up to 15% through its Bonus kilométrique and 10% for a vehicle fitted with two approved driver assistance systems. KBC does not publish an equivalent scale, but guarantees the same price wherever you take out the cover.

AG's Bonus kilométrique kicks in below 25,000 km a year, or 15,000 km for a diesel vehicle. That threshold is high: most Belgian commuters meet it without effort. In practice, a driver covering 18,000 km a year in a petrol car ticks the box without changing their habits, which makes this discount far more accessible than the classic "low mileage" discounts on the market.

Good news for anyone who hates negotiating: KBC's price lock removes the channel question. You will not have to wonder whether the branch gave you a better price than the website. AG, by contrast, always goes through an intermediary who draws up the quote, which leaves some room for discussion on the formula chosen and the add-ons.

Is a telematics box required for these discounts?

No, neither at AG nor at KBC for the discounts mentioned here. AG's Bonus kilométrique is based on declared mileage, not on a tracker. Box-based offers do exist on the Belgian market, but they mainly target young drivers, not the 40 to 55 profiles whose bonus-malus is already at rock bottom. To understand how this coefficient weighs on your premium, see our guide to bonus-malus in car insurance.

Where and how do you sign up with each?

This is the most structural difference, and it is rarely mentioned. AG Insurance does not sell direct: its car contracts go through independent brokers and through the BNP Paribas Fortis network. KBC sells online, in bank branches and via its insurance agents, at the same price.

That difference changes your journey. At AG, you will never see a displayed price: everything starts from a quote drawn up by the intermediary, who can adjust the formula, the deductible and the add-ons. At KBC, you run a simulation and sign up on your own in a few minutes, and a local agent picks up the file if a claim occurs, even for a contract signed online.

Careful: both contracts are concluded for one year with tacit renewal, but the notice periods advertised differ. AG's Top Omnium sheet mentions 3 months' notice before the renewal date; KBC states 2 months. As a consumer, you can in any case cancel at any time from the second year of insurance, taking effect two months after sending the registered letter. This right prevails over the notice period announced in a sales brochure.

The limits to know before signing

Neither contract is perfect, and the exclusions are more alike than the brochures suggest.

At AG, the Top Omnium does not cover damage due to a construction defect, wear, lack of maintenance or improper use of the vehicle. It also excludes theft if the anti-theft system required by the company was not in working order at the time of the events. That clause deserves an annual check if your car is getting older.

At KBC, the partial omnium does not cover damage to your car after an accident: you need full omnium for that. It excludes theft that you made easier by leaving the car unlocked on the public road, as well as damage linked to wear or an obvious lack of maintenance. Your own injuries as a driver fall under separate driver insurance, at both companies.

Should you also ask Baloise for a quote?

Yes, if you want a serious third point of comparison for this profile. Baloise structures its car offer into small and full omnium, allows a wide choice of deductibles on material damage, and in principle covers theft, fire, broken glass, natural events and animal collision with no deductible.

The point of a third quote is not to find €30 less. It is to spot the parameter on which the first two served you badly. An experienced driver with no claims has real bargaining power: this is the profile every company wants, and the one on which they most readily agree to adjust a deductible or include an add-on.

How many quotes should you ask for in practice?

Three is enough, provided they cover identical guarantees. Beyond that, the time invested pays little. Always ask for the same trio: deductible for material damage, length of payout at purchase value, replacement vehicle. Our general comparison of the best car insurance in Belgium sets AG and KBC against the other players on the market.

AG Insurance or KBC: the verdict for your profile

One last reflex, whichever company you pick: reread the "deductible" line in your policy schedule once the contract is signed. It is the figure nobody checks and the only one you will pay out of your own pocket. To find out how this amount is negotiated and compared, see our guide to the deductible in car insurance.
