Hi,
People have been "done" for "No Tax". or "No SORN", even when their car is in a locked garage. I have "done" cars myself, in the bad old days. Sorry, it was my job, (DVLA, 1962 to 1985) so no other option.
Check your insurance POLICY for REFUNDS ... the % of refund drops rapidly, possibly zilch after 6 months.
So look for LAID UP POLICY ... you may be able to transfer the true balance to your next car, yonks in the future.
Or what's the chances of "the sky falling" on your car while stored, or it being stolen. Maybe it's worth letting the policy run.
I think there will be something in your policy about LAID-UP cover, which (I think) will cover theft and third-party claims by a Clefti-wallah who injures himself while try to half-hitch your motor. I'd anticipate a much lower premium ... you can only ask.
If you do not yet have FULL NCD, this years bonus will be lost if you do not let it run the full.
Your insurance may cover your garage against fire, or WHY.
You may be insured to drive vehicles that you do not own ... useful sometimes ... but it will be TPO.
I doubt that bit has any refund value (come back and tell us), so either change it to laid up cover, or let it ride.
READ YOUR POLICY.
