Corrections policy
How material errors in our guides and calculators are investigated.
How to identify a correction
Provide the MMG URL, the exact passage or result, a concise description of the problem, and the source or scenario showing the issue. Do not send banking details, identity documents or complete moving addresses unnecessarily.
What happens when an error is confirmed
Material errors should be investigated against official or professional references, corrected on the relevant page and checked against affected calculators, summaries, structured data and related guides. Significant revisions should show a truthful update date.
Urgent inaccuracies
A potentially harmful error involving tax, tenancies, property transactions, privacy or personal safety takes priority over formatting issues. Content can be withheld from indexing while further verification occurs.
How to contact MMG
Use the protected form on MMG's Contact page to report corrections. Messages are stored privately and reviewed manually. A verified legal operator identity and correspondence address are still outstanding.
