Insurance - I messed up - 24 hrs without cover

Hi

I’m incompetent rather than a mastermind criminal. Is there any hope for me?

I had a renewal quote for my car insurance a few weeks ago and obviously like everyone, it had rocketed up so caused me to shop around. I found a new company and took out insurance starting today on 23rd March.

About 0100 this morning my old insurance company emailed me saying “you’re no longer insured. Here’s your no claims blah blah ….your cover ended 2359 on 21st March 2024”

I called them and asked if I could extend it by a day - “no way” they said. I asked the new company if I could bring my insurance forward 24hrs - “no way” they say.

The car was off the road (ie on my driveway). Wasn’t driven. Nothing happened to it - so there’s no claims happening for that one day.

I didn’t think it was a big deal but my mates just been telling me about the continuous insurance rules - so - can I get insurance for 1 day yesterday? Am I worrying over nothing? Because it wasn’t driven - is it irrelevant?

Ta for any advise
