how do I provide previous claims history to the insurer

You provide claims history with policy overview and claims statement

An insurer usually wants to know three things: what claims have occurred in recent years (often three to five years), what was the cause, and how was the claim settled. The supporting document for this is a claims statement or renewal overview from your current or previous insurer. That overview shows per policy the reported claims, the amounts paid out, and whether a file is still open. If you don't have that overview yourself, you can usually request it from your current insurer or broker; they keep this as standard.

If you have no claims history because the company has just started, or because nothing happened in the requested period, then "no claims known" is a valid answer — provided you can support that with the term of the existing policy. An insurer asks this separately from the question about financial health; the latter concerns solvency and turnover, not claims history, and is explained separately under insurer asks about our financial health what should I enter. Note that this is a different supporting document than what a bank asks for: a bank looks at payment behaviour and credit risk, an insurer at claims history — why those questionnaires differ so much is explained under why does the bank ask completely different questions than the insurer when it is about the same thing.

No statutory retention requirement, but standard market practice

There is no provision from the Trade Register Act 2007, the Anti-Money Laundering and Terrorist Financing Prevention Act, or the CSRD Directive (EU) 2022/2464 that regulates claims history as such — these are regulations on trade register data, customer due diligence on money laundering risk, and sustainability reporting respectively, and claims history falls outside those three. The question about claims history stems from the insurer's own acceptance policy: it assesses risk based on the past, not on a legal obligation on your part. The claims statement that brokers and insurers exchange is therefore market practice and not a legally prescribed document.
