If you took it out last year, thats probably got over the first hurdle of no claims within three months of the start of the policy.
I claimed on mine and it was very helpful. I insured to a sum of £1200 pcm and a max of 12 months claiming. The reality is that attendance at the job centre was mandatory every 2 weeks for paperwork to submit each month to the insurance claim office. I also had to submit evidence of job searches, letters of application, interview appointments too.
Its not an easy ride of insuring for a year then actually taking a career break. The pressure for evidence ramps up each month. I think mine wanted 6 application letters and evidence and that was ramping up each month too. I guess the insurance office want you off their books asap.
Overall, it was worth it. I took out more than the sum of the premium. Consider checking to see if you can still pay the premium whilst claiming as I could have a subsequent claim after a period of 6 months too.
Hope this helps. It was a piece of mind for the mortgage when I was made redundant after 13 yrs service with the satutory minimum of £5.5k and having to work my notice…
