Insuring a used car in Belgium: decide before you buy

Insuring a used car is decided before you sign the order form, not after. The car's age closes some omnium formulas, the invoice fixes the value the insurer will one day pay back, and any damage already present on handover day will in principle stay at your expense. Three irreversible decisions, often taken in ten minutes at the counter.

Why is cover for a used car decided before signing?

Because the insurer does not look at the car you think you are buying. It looks at a date.

The date of first registration, printed on the registration certificate, decides which formulas you can still get. The subscription date decides the starting value. The start date of cover separates covered damage from damage that never will be. All three dates are fixed when you sign, and none can be caught up at the next renewal. That is the thesis of this article, and I defend it with the catalogues of two Belgian insurers in front of me.

The usual reflex runs the other way. You buy, you drive home, then you call your broker to "move the plate across". For mandatory liability cover that nearly always works. For the rest, it is often too late.

The car's age closes formulas, one by one

In October 2026 I reread two public product documents: the "used vehicle" sheet of a range distributed by P&V (edition 10.2019, put online in 2024) and Allianz's Car Plan information sheet (February 2023). They do not say the same thing, but they follow the same logic: omnium is reserved according to the car's age on the day cover is taken out.

The last column is not a rumour. The P&V sheet restricts vehicle assistance to cars under 10 years old, and the AXA assistance conditions read for our article on breakdown cover set the same limit when the contract is concluded.

A car aged 4 years and 11 months and one aged 5 years and 1 month cost roughly the same at the dealer. At the insurer, they do not live in the same catalogue.

How much is your used car worth to the insurer?

Less than its price tag at the dealer, and according to a rule written in advance. The P&V sheet offers two bases: the list value excluding VAT, the official price of the new car with options, or the invoice value, meaning what you actually paid. It also offers degressive depreciation of 15% a year, counted from first registration and not from your purchase. The table below applies this published scale to a car with a €30,000 list value.

Take your 3-year-old used car bought for €19,500 from a garage. Insured on list value under the degressive formula, it is worth €18,423 to the insurer in year one, €1,077 less than your cheque. Insured on the invoice, the starting base is your €19,500, then the chosen depreciation applies. The sheet also offers progressive depreciation of 1% a month, counted from first registration, and states that beyond 60 months the insurer leaves this system to check the real value. Neither option is better in absolute terms. You choose once, at signature, and the invoice is your only proof. Our article on market value, agreed value and new-for-old shows how these bases play out on the day of a total loss.

Allianz, for its part, states that used cars up to 5 years old can be insured on their invoice value. Past that point, this door closes too.

The objection: liability cover is enough to get home

True, and it is the most serious objection to my thesis. Liability cover (RC) is the only compulsory insurance in Belgium, imposed by the Act of 21 November 1989, and you nearly always get it the same day. The insurer or broker fills in the registration request, the well-known pink form, and sends it electronically to the DIV, the vehicle registration directorate of the Federal Public Service Mobility. The plate and certificate then arrive by post. On this point nothing is urgent beyond handover day.

But there is a Belgian constraint that buyers discover in the car park. The plate follows its holder, not the car: the seller leaves with theirs. So you cannot "drive home on their plates and their insurance", even for twenty kilometres. Without your own registration, the car cannot legally be driven.

And liability cover only pays for damage you cause to others. The day the car you bought yesterday is scratched, stolen or destroyed, liability cover pays its owner nothing.

Is damage already present on purchase day covered?

In principle, no. Never.

An insurance contract covers an uncertain event that occurs during its term. The Act of 4 April 2014 on insurance builds the whole contract on the notion of a claim, meaning the occurrence of the insured event. A dent on the rear wing, a cracked windscreen, a kerbed wheel: if they existed before cover started, they are not claims, they are defects of the car you bought.

The problem is rarely the exclusion itself. The problem is proof. Three months after buying, you report a deep scratch on the door. The assessor notes old marks, a paint touch-up of some age. Who proves what, and since when? With no dated photo from handover, the discussion starts badly, and forfeiture of cover is not even needed to refuse payment: it is enough that the damage plausibly predates the policy.

Hence a four-minute habit before leaving the seller. Photograph all four sides, the roof, the wheels, the windscreen and the odometer, with date and place visible. Some insurers themselves ask for photos or an inspection before granting omnium on a used car: your specific conditions will say so.

Roadworthiness test, Car-Pass: two papers that weigh on cover

Two documents in principle accompany every used car sold in Belgium: the roadworthiness inspection certificate and the Car-Pass, which records mileage since first registration in the country. People see them as sale papers. They also affect your insurance.

The roadworthiness test first. Allianz's Car Plan sheet lists among its main exclusions a vehicle without a valid inspection certificate, except during the normal trip to the test centre. Ethias likewise excludes total loss of a car without a valid test, as we read in its chapter on mini-omnium. A used car bought with a certificate expiring the following month is therefore a cover risk, not just a formality.

The rule is changing, and not the same way everywhere. In Flanders, a reform announced for 1 January 2027 removes the mandatory test before selling to a Belgian resident, while the Car-Pass remains required. In Wallonia and Brussels, check the rule that applies on your purchase date with the approved test centre. Sale test or not, your contract's exclusion still binds you once the validity date has passed.

Then the Car-Pass. The mileage it shows is the one you will carry into your risk declaration, and any gap with the odometer must be reported. Our article on declared mileage explains why that figure matters so much. For a used electric car, KBC also announces a battery health report from 2027: keep it with the invoice.

Which formula for which used car?

My thesis has a limit: a decision taken early is not necessarily an omnium. For a 9-year-old city car, paying for omnium on an insured value of 23% of the new price rarely makes sense, and mini-omnium already covers theft, fire, glass and hail. For a recent used car worth more than €15,000, on the other hand, letting the 5-year window pass can cost you an uncompensated total loss. Our mini-omnium vs full omnium comparison gives the tipping points.

One rule holds for every used car: choose the formula knowing the insured value, not the premium.

Seven documents to gather before signing the order form

Ask the seller for them before paying, then send them to your insurer or broker:

• The seller's registration certificate, for the date of first registration, the one that decides your formulas.
• The certificate of conformity, essential for the registration request to the DIV.
• The Car-Pass, to compare with the odometer before signing.
• The latest inspection certificate, with its validity date.
• The invoice or deed of sale, the base if you insure the invoice value.
• Your dated photos of the car from every angle, taken before the first trip.
• The written insurance quote, with formula, insured value and depreciation method in black and white.

If the car is not in your name, first read our article on insuring a car not in your name: the policyholder and registered keeper must be consistent from the first request.

To compare the formulas still open at your car's age, the comparison tool lines up covers and exclusions, the ranking of the best car insurers details what each company covers and refuses, and the quiz frames the useful level of cover. The papers to keep on board are listed in our article on mandatory car documents.

Belgian car insurance contracts fall under the Act of 4 April 2014 on insurance. Registration is handled by the DIV, part of the FPS Mobility and Transport. In a dispute with your insurer, the Insurance Ombudsman, the free out-of-court complaints service for Belgian insurance customers, handles consumer complaints, and the FSMA, the Belgian financial services and markets authority, supervises the conduct rules of intermediaries. The insured value figures come from the used vehicle product sheet published by P&V (French original); the Flemish roadworthiness reform is summarised by KBC (25 August 2026). These documents illustrate market practice and do not replace your own conditions.

This site informs and compares. It is not an insurance intermediary and gives no individual recommendation: your specific conditions, and they alone, decide.
