Your visa has a machine readable bottom strip which contains the passport number (this image I have found in Google Images by searching for UK visa and I have only edited it to mark the passport number):
if this is your expired passport then all is well. I have traveled with a visa in my expired passport countless times (into the USA but that’s immaterial) this is absolutely normal and accepted. If this is your current passport then you need to talk to the visa issuer immediately. This would be really bad because even in this case where you are absolutely not at fault you might find it challenging to just get a visa reissued for free. I would definitely not attempt travelling with a visa with the wrong passport number in it even if I hold the correct passport in my hand, as this would be unusual and god forbid to try to cross such hostile borders as the UK (or the USA) with an unusual case.
