Mortgage Rate Review

I currently have a tracker mortgage with NIB (ECB + 0.79%). I contacted them yesterday to request a rate review and was told that i could reduce this to ECB + 0.51% by switching to a L.T.V. mortgage but that i needed to have the house valued.
I contacted an auctioneer who's charging 130 euro for this. Is there any way around paying this and still getting the rate change?
Also, i saw from a previous post which i can't find now, that someone is paying their mortgage forthnightly with NIB. We requested this last year when we took out our mortgage and were told that NIB don't do this - Clearly not the case! Advice on how to go about getting this would be appreciated. It would also be helpful to know where this is happening so we could say it to our mortgage consultant - we are living in Galway.

I had my rate revalued last month and the bank required a valuation. I didn't mind this as the drop in rate of .3% covers the cost of the valuation in less than 2 months.
