Fixed Rate Mortgages in Ireland: Should you fix in 2026?

While we can’t control most of those twists and turns of life, there are areas where a bit of certainty can go a long way.

One of the places where this can be valuable is your mortgage. A long term Fixed Rate Mortgage like the Avant Money One Mortgage allows you to get fixed repayments for the entire lifetime of your mortgage. This way you’ll never have to worry about your rate changing for the life of your mortgage. In this article we go through all you need to know about Fixed Rate Mortgages and when they may suit you.

Why fixed mortgage rates in Ireland matter more than ever

If you’ve been asking yourself, “should I get a Fixed Rate Mortgage?”, you’re not alone. The main benefit of a Fixed Rate Mortgage is that your repayments stay the same for a set period, even if interest rates rise. It gives you a sense of control in a world where costs can change quickly.

But here’s the catch in Ireland:
Most fixed mortgage rates only last a few years.

After that:

• Your rate and repayment can change
• Your monthly budget can become less predictable

So while a standard Fixed Rate Mortgage can help in the short term, it doesn’t always remove uncertainty in the long run. This doesn’t have to be the case and is why a long term Fixed Rate Mortgage may be worth considering.

One Mortgage. A long term Fixed Rate Mortgage for the duration of the term

The One Mortgage is Ireland’s only mortgage that offers a fixed repayment for the entire mortgage term.* This way you can spend less time thinking about your mortgage, and more time focusing on the things that matter.

With One Mortgage:

• Your rate will stay fixed for the full term
• Your monthly repayments won’t change for the entire lifetime of your mortgage

It’s a simple concept, but a powerful one.

Is One Mortgage right for you?

There’s no one right answer, but it comes down to what is important to you. If you’re comfortable with some level of change in your repayment, a standard fixed or variable rate might suit.

But if you would like a more stable mortgage product, that’s where One Mortgage may be more appealing.
That’s especially true if you are:

• A first time buyer trying to plan your finances from day one
• A switcher looking to protect yourself from future rate changes
• A home mover dealing with new costs and commitments

You can’t control the Irish weather. You can’t predict every cost that’s coming your way. But you can choose a mortgage that keeps things simple.
