There's no lift on the bonus ladder: reaching the higher classes takes claim-free years, one at a time. The core rule is simple – a claim-free year, one step up – but the details hide a few conditions that trip people up without them ever realising it.
Your class isn't based on the calendar year but on the policy's observation period. Under the rules in force, your class moves up by one if the vehicle typically had insurance cover for at least 270 days during that period, and no claim became known that obliged the insurer to pay out. Both conditions matter: being claim-free alone isn't enough if cover was missing for most of the year.
This is why bonus comes up in the article on suspension too: a long suspension can mean missing out on that year's step up.
The step up takes effect at the start of the next policy period – the renewal date. In practice, this means renewal offers are already calculated with the new, one-better class; the class doesn't change mid-term. That's also why it's natural to take a fresh look if it's warranted or you ask: it's when the new class, the new tariff publications, and the fresh picture of any change in your circumstances all come together – that's what the renewal routine article covers.
There are three typical things that slow you down. The first is a gap in cover: the gap that follows lapse for non-payment not only brings an uncovered-period fee but also puts that year's step up at risk. The second is a longer suspension – because of the typical 270-day condition. The third is a claim that only becomes known later: under the rules in force, the injured party can report a claim within a certain deadline even after some time has passed, and the class still drops even if you would otherwise have moved up.
Honestly: you can't speed up claim-free years – the system rewards time itself. What you can do is not lose what you've already earned. That means keeping payments on track (see the routine article), timing any switch with no gap in cover, using the proper transfer when you change cars, and, if you cause a claim, weighing up whether it's worth letting the insurer pay for a smaller one. Your claims history is an asset – it's worth treating it as one.
Here's what the typical path looks like: your first policy starts from A00; every observation year that closes claim-free with enough cover is one step – B01, B02, and so on. Ten claim-free years gets you to B10, the top of the ladder. Along the way, life can intervene: a car change (smooth, with the class transferred), a longer suspension (that year's step may be missed), or a minor collision (typically two steps back, then building up again). The key point is that the ladder is patient: it neither forgets nor rushes – it gives the classes back after a claim at the same pace it built them up in the first place. For anyone who's been through it once, B10 isn't a status but a way of doing things: tidy administration and careful driving, year after year.
