Guides

One question per page, answered from the source

Each guide takes one question people get stuck on and answers it completely. Every rule, date and code is taken from the regulator's own document, which the guide names, links and dates. Where a fact could not be checked against a primary source, it is not on the page.

Check your own register

The guides explain the rules; the DORA Register Checker runs them on your file, in your browser, with nothing uploaded. If the register needs more than a check, the fixed-price services are listed with their prices.

Try it on your own file first

Every tool here runs in your browser and uploads nothing, so you can see what we would see before telling us anything at all. When it is worth a conversation, send the real extract and the question you actually need answered.
