weekend car no insurance for 2 weeks- SORN?

hello all,

I cleverly have left getting my car insurance sorted out for my weekend car very last minute. essentially if i insure it from Tuesday the cheapest quote for the year is 2200, but if i start the insurance in 2 weeks time, it comes down to 1600...

I won't be driving the car at all of course whilst it isnt insured as I have my daily driver. The question is, do I have to SORN it for these 2 weeks, or should I leave it? I have my own driveway where it is parked in front of my wife's car and blocked from public view.

Thanks

OK thanks.

Just seems like a lot of faff and work for literally 14 days when the car is going to be parked, on my private land at the end of a private road in a quiet suburb
