Aggravated risk in car insurance: the 5x threshold

In Belgian car insurance, an aggravated risk is a profile the insurer prices well above its base rate: heavy malus, cancelled, listed or very young. The figure comes from the Bureau de Tarification, the state-backed tariff bureau run by the Fonds commun de garantie, which can step in once the premium offered reaches five times the insurer's lowest premium.

On the 26 January 2026 liability grid, that threshold sits between EUR 1,350 and EUR 2,430. The bonus-malus alone almost never gets there.

What is an aggravated risk in car insurance?

A profile the insurer judges costlier than average and charges accordingly. The term has no single legal definition on the pricing side: it is trade language for heavily malus-rated drivers, drivers cancelled after a claim, drivers listed in the insurers' Datassur file, or very new drivers.

Do not confuse it with aggravation of risk during the contract (change of use, vehicle or garage), which the policyholder must in principle declare under the law of 4 April 2014. Same word, different problem.

At what premium does the Bureau de Tarification step in?

Five times the insurer's lowest premium, according to CallMePower and HelloSafe. That minimum targets a middle-aged driver, in the countryside, at the best bonus level.

Each insurer's best profile is not published. As an approximation I use the liability grid from Mon-Assurance-Auto, which simulates a driver at the lowest bonus-malus: 10,000 km a year, read on 26 January 2026.

The threshold moves by EUR 1,080 from one insurer to another. The same EUR 1,700 offer opens the Bureau's door at Yuzzu, but not at AG Insurance.

Does the malus alone clear that threshold?

No. On the reference scale, degree 22 weighs 200% of the base premium and degree 0 only 50%: a ratio of 4, not 5.

Take Ethias at EUR 363 for the lowest degree. The table applies the reference scale's percentages, as published by Selectra and HelloSafe (read in October 2026).

Even at the top, EUR 363 is missing. Other criteria (age, engine power, area) fill the gap: a 25% extra is enough at degree 22, 92% at degree 19.

Ethias's own scale puts the top at 219% for a floor at 45 to 54% depending on the HelloSafe passage, a ratio of 4.1 to 4.9. Still under 5.

Which cases count as aggravated risk, and what to do?

The table sorts the situations insurers most often treat as aggravated, with the first useful move. It does not replace a quote.

Which documents to gather before applying to the Bureau?

The application stands or falls on the file. Keep these at hand:

• the three written refusals, dated, from three different insurers;
• or the three offers judged excessive, with the ratio to the lowest premium worked out;
• your claims history certificate, obtained on Carattest;
• vehicle and usage data identical to what you declared to the insurers.

A broker licensed by the FSMA (Belgium's financial regulator) assembles this faster than you. The procedure and the Datassur file are covered in our guide to high-risk and cancelled drivers.

How long does the procedure take?

Eight days for the Bureau's decision, up to a month to set the premium. The offer stays valid a month. Refused, it blocks any new request for 8 months, and accepted cover runs for a year (HelloSafe).

Do not drive uninsured meanwhile: liability cover is compulsory, and in an uninsured accident the Fonds commun de garantie compensates the victim before turning against you. I point to the FSMA for the general framework, since the Fund publishes its own pages.

Can you avoid getting that far?

Usually yes, and it costs less. A profile surcharge can be negotiated or sidestepped: higher deductible, fewer declared kilometres, a clarified main driver. The priced levers are in our article on lowering your premium.

Keep one calculation in mind: an at-fault claim already costs EUR 535 of premium over five years for the reference profile. Repeating it slides you up the scale, then toward the threshold.

Method, reference profile and sources

Site reference profile: 35-year-old driver, Volkswagen Golf 1.5 TSI, Flemish Brabant, no claims for five years. The twelve liability premiums come from Mon-Assurance-Auto (Yago S.A., FSMA-licensed broker no. 114863), read on 26 January 2026: woman born in 1968, lowest bonus-malus, 85 kW diesel Golf, Court-Saint-Étienne, 10,000 km a year. That profile differs from ours; only ratios are claimed as transferable. It approximates, without equalling, the best profile insurers have in mind.

The five-times threshold, the three refusals, the 8-day and one-month deadlines, the 8-month wait and the one-year cover are those published by CallMePower (updated 14 April 2025) and HelloSafe (page dated 25 August 2022), read on 4 November 2026. HelloSafe also cites a three-times threshold for the deductible that CallMePower does not repeat: confirm with the Bureau. Scale percentages come from Selectra and HelloSafe, also read in October 2026, with the inconsistencies noted above. Every euro threshold, ratio and surcharge is our own calculation, an estimate and not a Bureau tariff.

Legal framework: the law of 4 April 2014 on insurance; consumer information on Wikifin and on the FPS Economy page on bonus-malus. In a dispute with an insurer, the Insurance Ombudsman is competent.

In short

The Bureau de Tarification opens at 5 times the insurer's lowest premium: EUR 1,350 at Yuzzu, EUR 1,815 at Ethias, EUR 2,430 at AG Insurance, EUR 1,824 on average. The bonus-malus caps at 4 times; the rest comes from the profile. Run a quote, put offers side by side in the comparison tool and see the ranking of the best car insurance before filing anything.
