You can't plead the fifth and then raise things in court later, though. Which does make it markedly different. And I thought in limited circumstances that there was no right to be silent, that it was an offense not to inform the LEOs:

I'm pretty sure that this, http://www.legislation.gov.uk/ukpga/1987/38/section/2 (Criminal Justice Act 1987), says you can't refuse to answer questions or provide documents but that your answer can't be used alone as evidence against you, it must be corroborated. That is, no right to silence.
