How do I protect NCB with no car.

[ruff'n'smov]

So pal of mine is working in the Falklands and doesn't want to loose his hard earned NCB, he gave up his car last year and now is wondering how to keep his NCB going.

Informed answers please.

How long is he away for? NCD can be kept for two years without being used.

Insuring a SORN scrapper with a tiny engine at the end of the 2 years is about the only way I can think of
