Customers on AIB, EBS and Haven tracker mortgages will be able to move home but still retain their mortgage terms from tomorrow.

AIB will add 1 per cent to the customer’s existing tracker mortgage rate for the duration of their tracker term , if they move.

The bank said any additional funds customers wish to borrow would be at prevailing new business rates.

AIB is also introducing revised fixed rates for new residential owner-occupier mortgage customers tomorrow, including a new business one year fixed rate of 3.5 per cent.

"These enhancements to our mortgage offerings further underline our commitment to supporting the residential property market and our customers who are considering moving home," head of mortgage business development at AIB, Michael Quirke said.
