You are dishonestly retaining something which you know is not yours

That's an appropriation of property for the purposes of the Theft Act

It's the same as hanging on to the change if someone mistakenly gives you change for a twenty when you'd given them a tenner. As soon as you realise and decide to hang on to what isn't yours, you're dishonest
