Disclosures

Current commercial relationships

None. This site currently has no advertising, affiliate links, sponsorships or paid features.

YouTube advertising

Embedded YouTube videos may show adverts. Those adverts and any income from them belong to YouTube and the video's owner, not to us.

If this changes

• Commercial links will be labelled next to the recommendation, not only on this page.
• They will use rel="sponsored".
• Programme-required statements will appear where required. For example, if we join Amazon Associates: "As an Amazon Associate I earn from qualifying purchases."
• Payment will never decide which videos we include or how they are ordered.
