Approved Garage and Car Insurance: 250 to 500 € Deductible

Yes, the garage you choose after a claim can change your omnium deductible. At Ethias it goes from 500 € to 1,000 € outside the network of approved repairers, at Belfius it gains 250 €. At one claim every eight years, that choice costs 31 to 63 € a year.

The calculation is one multiplication.

What does an approved garage change in the omnium deductible?

The deductible goes up when you leave the insurer's network, or down when you stay in it, depending on how the contract is written. The table gathers what insurers' public documents allow us to verify, read on 29 October 2026 for the own-damage cover of omnium, the comprehensive cover that repairs your own car.

Only three insurers out of six publish an amount. For the others the increase exists but is read in the special conditions, and that is where to look before a claim, not after.

How much does choosing your own garage cost, in euros?

Exactly the extra amount, not a euro more. The insurer pays the rest of the bill, whichever garage does the work.

Take the reference Golf and 4,000 € of damage assessed by an Ethias network repairer. Here is what you pay depending on the deductible in the contract.

A cheaper independent garage therefore earns you nothing: the saving goes to the insurer, the increase stays with you. One exception exists, the small repair. If the independent charges 450 € where the approved garage would charge 800, you pay 450 € at the first and 500 € at the second, deductible included, because damage below the deductible is not reimbursed.

How often is the extra amount actually paid?

Only in years when a claim is paid, so rarely. The increase is weighted by frequency, and the frequencies in the table are working assumptions, not statistics: one paid claim every ten, eight or five years.

An Ethias driver who always went outside the network would therefore pay 625 € over ten years, each time 1.6 % of the Golf's value (500 ÷ 31,670). The totals only hold for someone who goes outside the network at every claim: a single visit to the network resets the counter.

What does the approved network add besides the deductible?

At Belfius and DVV, the repair rules of 14 November 2025 list them in black and white. They apply when the insurer takes the damage in charge, under omnium or after an accident covered by the direct settlement scheme between insurers.

• a deductible with no surcharge for the own-damage cover;
• a class A replacement car during the repair, limited to 6 consecutive days after a total loss;
• a lifetime guarantee on the repair, until the vehicle is changed or sold;
• direct payment of the invoice to the garage: you pay the deductible and the non-recoverable VAT;
• collection and delivery of the vehicle in Belgium, free storage during the expert's assessment (45 days at most after a total loss), cleaning and a general check.

The replacement car still needs a price. Working assumption, not attributed: 40 € a day for a compact. Seven days off the road are then worth 280 €, more than Belfius's 250 € increase. Our article on the replacement car details the conditions.

In which cases does the increase not apply?

In four situations that the documents read describe.

Fédérale Assurance: a 395.88 € discount rather than a penalty

Fédérale presents the same thing the other way round. Its deductible halved, 1.25 % capped at 625 €, is worth 395.88 € on the Golf instead of 791.75 € at 2.5 %. The conditions are being at least 30 with a bonus-malus degree of 3 or less at signing (the 0-22 scale that sets your third-party liability premium), and repairing at a contracted repairer. The repair must also reach 500 €. Same mechanism as elsewhere, different packaging: a 395.88 € gap depending on the garage.

Approved garage or free choice: how to decide in five steps?

1. Find the out-of-network increase in your special conditions, often on the deductible or approved repairer line.
2. Multiply it by the frequency you retain: 62.50 € a year at Ethias with one claim every eight years.
3. Compare with what the network brings: replacement car, guarantee, direct payment.
4. Check the repairer list before signing a quote and keep the written confirmation.
5. If your usual garage is not on it, ask the insurer, before any claim, whether an exception exists.

On the amounts published here, the calculation favours the network as long as your garage is not part of it. Free choice is justified by a specific attachment, a specialist body shop or proximity, rarely by price.

The two choices add up. A 1,000 € deductible taken to lower the premium becomes 1,500 € outside the network at Ethias, which is 4.7 % of the Golf's value. Our article on choosing the deductible amount covers the other half of the calculation, and the one on the threshold deductible shows what changes with a 500 € threshold. Before reporting small damage, also reread reporting a claim or paying out of pocket.

Method, reference profile and sources

The site's reference profile: 35-year-old driver, Volkswagen Golf 1.5 TSI, Flemish Brabant, no claims for five years, about 15,000 km a year. Value used: 31,670 € including VAT, Belgian list price read on 31 August 2026 in the Moniteur Automobile catalogue. Fédérale's deductible percentages apply to that value. No premium is compared here: the gaps are deductible amounts, read in insurers' documents.

Claim frequencies, the 40 € a day replacement car rate and the totals are assumptions and in-house calculations, never statistics. Amounts may differ with your cover and signing date: the contract prevails. The legal framework is the law of 4 April 2014 on insurance.

This site compares and calculates. It does not sell insurance, is not an intermediary and gives no individual recommendation: speak to your insurer or an FSMA-authorised broker. For a dispute over the deductible applied, the Insurance Ombudsman acts free of charge, and the Tariff Bureau (Bureau de Tarification) remains the remedy for a driver refused third-party liability cover.

Summary

Leaving an insurer's network costs 250 € at Belfius, 500 € at Ethias, and a 395.88 € discount lost at Fédérale on the Golf. At one claim every eight years, that is 31.25 to 62.50 € a year, and zero if you stay in the network.
