Tracker mortgages in Ireland: should you ever switch?

A tracker mortgage is a kind of variable rate that follows the European Central Bank's rate. Lenders no longer sell them, so the ones that exist are worth understanding. This guide explains how a tracker works, why most people keep theirs, and the few cases where moving off one can pay.

How a tracker works

A tracker charges the ECB rate plus a margin. The margin is a fixed percentage written into your loan contract when you took it out. It never changes. See the glossary for the terms here.

Say your margin is 1%. The ECB rate is 2.50% since 16 September 2026. You pay 3.50%. If the ECB raises its rate by 0.25 of a point, you pay 3.75% within days. If it cuts by 0.25, you pay 3.25%.

That is the whole mechanism. The lender has no say over your rate once the margin is set. Our ECB guide shows the 2025 and 2026 moves.

Strictly, Irish trackers follow the ECB's main lending rate rather than the deposit rate the news reports. The two move together, by the same amount, on the same day.

What your tracker costs you now

Your rate depends on your margin. The table shows the rate at the ECB rate on 21 October 2026, taking the deposit rate of 2.50% as the illustration.

Compare that with the Central Bank's averages for new mortgages in August 2026: 3.49% for fixed and 4.16% for variable. A tracker with a margin of 1% or less was close to or below the average new fixed rate. A tracker with a margin of 2% was above it.

Find your margin on your loan offer or your annual statement, or ask your lender.

Why most people keep their tracker

There are three reasons trackers are valued.

1. The margin is fixed for life. A standard variable rate can be raised by the lender at any time. A tracker cannot. Your rate only moves when the ECB moves.
2. There is no breakage fee. You can overpay as much as you like, clear the loan, or switch, with no charge for leaving.
3. You cannot get it back. Once you move off a tracker, the lender has no duty to give it to you again. Lenders stopped selling them years ago.

Over the life of a loan, a low margin has often cost less than any fixed rate on offer. That is history, not a forecast. Nobody knows the ECB's next move.

When switching off a tracker can pay

There are a few situations where the sums can favour a move. In each one, do the sums before you act.

A high margin

A tracker with a margin of 2% or more costs 4.50% or more at the current ECB rate. That is above the average new fixed rate in 2026. A fixed rate removes the chance of a further ECB rise, but it also removes the benefit of a cut. The question is what you can live with.

Very little left on the loan

If you have a few years and a small balance left, the rate matters less than the costs of switching. A switch needs a solicitor (check the Law Society's register) at about €1,200 to €2,000 plus VAT, and a valuation at about €185. See what a conveyancing solicitor does. On a small balance, those costs can wipe out the saving. Keeping the tracker often costs nothing extra.

You need to borrow more

If you want to extend or renovate, your lender may let you keep the tracker on the existing balance and add a top-up at a different rate. Ask for that before you consider giving the tracker up. Our top-up guide explains the options.

You are moving home

Some lenders let you carry a tracker to a new home. The terms are usually a higher margin, for the old balance only, for the time left on the old loan. Any extra borrowing is at a new rate. Get the terms in writing before you sell.

A worked example

Say you have €150,000 left on a tracker with 12 years to run. Your margin is 1.5%, so your rate is 4.00%. A lender offers a 5-year fixed rate at 3.40%.

The saving over the fixed period is close to the costs. After five years the fixed rate ends, and the tracker is gone for good. If the ECB cut its rate in that time, the tracker would have cost less. If it rose, the fixed rate would have. The switching calculator runs this for your own figures, after every cost.

The lender's duty since March 2026

Since 24 March 2026, under the Consumer Protection Code 2025, a lender must tell you what you could save by moving to a lower rate it offers. For a tracker holder that letter may show a saving against a fixed rate. Read it carefully. The letter compares rates on the day. It does not include the value of a margin fixed for life, or the breakage fee on the fixed rate if you leave it early. Our changes page logs the rule.

A lender cannot take your tracker away because you ask about other rates. If it tells you otherwise, you can complain to the Financial Services and Pensions Ombudsman, free of charge.

What to check before you decide

• Your margin, from the loan offer or your statement.
• The balance and the years left.
• The fixed rates on offer, from our rates comparison, and whether your home's BER qualifies for a green rate.
• The costs of switching, from our cost of switching guide.
• Whether your lender offers you a fixed rate without a switch, which avoids the solicitor and the valuation.
• Whether you can get the tracker back if you fix with the same lender. Usually you cannot, but some lenders have offered it. Get the answer in writing.

A broker (on the Central Bank's register) can run the numbers with you. See what a mortgage advisor does.

Where this leaves you

Put your balance, your tracker rate and the fixed rate you are looking at into the switching calculator. It shows the saving after the solicitor and the valuation. If the saving is small, keeping the tracker costs you nothing. If you decide to move, the switching journey sets out every step, and get quotes finds the solicitor.
