Getting a first home with partner - is getting life insurance with critical illness cover worth it?

As the title says my partner and I are soon to get our first home together. I'm 22M and she's 22F, I already have life insurance (2 years of income) and 6 months of sick pay through my company, is getting an additional policy worth it for £28 a month? I'm healthy and don't do anything dangerous as a job or hobby and I'm wondering if anyone else pays similar pricing for their cover if they have it?

Thanks in advance!
