OOD film developing?

Ok the problem is I've acquired a reel of HP5 film and it's slightly out of date, by several years.

To develop it how much longer than the usual 7 minutes is it going to need?

Is there a formula that I could be using or will it just be trial and error?
Cheers, HG

You could do a clip test, just removing a short length of film and test developing that first. Then you can extend development for the main part if necessary. Plus 20% seems reasonable, but the clip test is best to make sure.

Agree with the clip test. I was shooting film till about half a year ago when I made the jump to digital but I still got Film in the Freezer (Bought lots cheap as there where still just in date. By placing them in the freezer you stop the emoultion from decaying. Take it out 24h before use and then develop as usual. No clip test needed then.
Kind regards

I agree with John on 20%, the problem is that you just dont know how it has been stored.

Thamks for the advice, now I've got an idea what to do I'll start to play with it.
