Pay lump sum off tracker mortgage or not?

Hi I'm new to this, and really need some advice, here is our situation:
Have tracker mortgage of 150,000 with AIB taken out in 2004 for 30yrs.
Balance of mortgage is approx €130,000
Hubbie has redundancy coming so we were thinking of putting 30k off mortgage.
Question is, is it worth our while doing this or not? We are extremely broke at the moment so having a lump sum there for a rainy day seems like a good idea, however if paying a lump sum meant that we reduced our monthly payments ths might be a better idea.
We have no plans of moving any time soon any neither of us are working at the moment as hubbie has serious illness!
Any advice would be very much appreciated,
thanks in advance.

I'd leave it in a high interest savings a/c with instant access eg Permanent TSB have one and then dip into it to help pay mortgage when you need it, effectively reducing monthly repayments. You can get better interest return on your savings than you would get from paying your tracker off early. However you have to make sure you don't just spend it. If you've a tendancy to just spend it then of course its better in the mortgage, or you could put half on mortgage and half in savings a/c. You need some money to be available for emergencies if it goes into the mortgage you won't be able to get it back so easy, if at all.
