The fixed vs variable mortgage decision is one of the most important choices you’ll make when taking out or switching a mortgage in Ireland. Get it wrong and you could pay thousands extra in interest or face hefty break fees if your circumstances change.
Right now, the Irish mortgage market is in an unusual position. After the ECB raised rates sharply between 2022 and 2023 to combat inflation, they’ve been cutting rates throughout 2025 and 2026. This has created a situation where fixed rates are actually cheaper than variable rates — something that wasn’t always the case.
This guide explains exactly how fixed and variable mortgages work in Ireland, what they cost today, who each option suits, and how to make the right choice for your situation.
How Fixed Rate Mortgages Work in Ireland
A fixed rate mortgage locks your interest rate for a specific period, typically between one and ten years. Most Irish borrowers choose either 3-year or 5-year fixed terms.
During your fixed period, your monthly repayments stay exactly the same regardless of what happens to ECB rates or what your lender does with their variable rates. If the ECB cuts rates by 1%, you keep paying the same amount. If they raise rates by 2%, you’re still protected.
When your fixed period ends, you don’t automatically get a new fixed rate. Instead, you roll onto your lender’s standard variable rate, which is typically much higher than competitive fixed rates. At this point, you need to either:
- Fix again with your current lender
- Switch to a new lender for a better rate
- Stay on the variable rate
The main downside of fixed rates is the break fee. If you want to exit your fixed rate early — whether to switch lenders, move house, or pay off the mortgage — you may face a penalty. How much depends on the lender and how interest rates have moved since you fixed.
How Variable Rate Mortgages Work in Ireland
Variable rate mortgages can change at any time, though in practice they tend to follow ECB base rate movements. There are three main types:
Standard variable rate (SVR): The lender’s default rate, typically the highest. You usually end up here after a fixed period expires if you don’t actively switch. Current average: 4.2%.
Tracker rate: Directly tracks the ECB base rate plus a fixed margin (e.g., ECB + 1.0%). If the ECB rate is 3.0% and your margin is 1.0%, you pay 4.0%. When the ECB cuts by 0.25%, your rate drops by 0.25% the following month. Very few Irish lenders offer new tracker mortgages in 2026.
Discount variable rate: A temporary discount on the lender’s SVR, usually for the first year or two. After the discount period, you move to full SVR.
The advantage of variable rates is flexibility. You can overpay, switch lenders, or pay off the mortgage entirely without penalty. The disadvantage is uncertainty — your rate and repayments can increase at any time.
Current Rates: Fixed vs Variable in October 2026
Here’s how rates compare across Irish lenders right now:
| Rate Type | Average Rate | Range | Typical LTV Limit |
|---|---|---|---|
| 1-year fixed | 3.8% | 3.5% - 4.1% | Up to 90% |
| 2-year fixed | 3.6% | 3.3% - 3.9% | Up to 90% |
| 3-year fixed | 3.5% | 3.2% - 3.8% | Up to 90% |
| 5-year fixed | 3.5% | 3.1% - 3.9% | Up to 90% |
| 7-year fixed | 3.7% | 3.4% - 4.0% | Up to 80% |
| 10-year fixed | 4.0% | 3.7% - 4.3% | Up to 80% |
| Standard variable | 4.2% | 3.9% - 4.6% | Up to 90% |
| Tracker (legacy) | 3.9% | 3.5% - 4.3% | N/A |
The best rates typically require at least 20% deposit (80% LTV) and evidence of strong income. First-time buyers with 10% deposits usually pay 0.2-0.4% more.
Notice that 3-year and 5-year fixed rates are nearly identical. This reflects lender expectations that ECB rates will stabilise around current levels over the medium term.
Why Fixed Rates Are Cheaper Right Now
In a normal market, variable rates are cheaper than fixed rates because you’re taking the risk that rates might rise. The lender rewards you for that risk by charging less interest.
But Ireland isn’t in a normal market right now. Fixed rates are cheaper because:
Lenders expect rates to fall further: The ECB base rate peaked at 4.0% in late 2023 and now sits at 2.75% in October 2026. Markets expect it to settle around 2.0-2.5% by 2028. Lenders are pricing 5-year fixed deals based on where they think rates will average over those five years, not where they are today.
Competition for fixed rate business: Irish lenders are fighting hard for new fixed rate customers because those relationships last longer and are less price-sensitive. They make less margin but gain stability.
Variable rate customers subsidise switchers: Many borrowers on standard variable rates haven’t shopped around in years. Lenders use these high-margin customers to fund competitive fixed rate deals for new business.
This won’t last forever. As ECB rates stabilise and the gap between fixed and variable narrows, we’ll likely return to a more normal market where variables cost less than fixed rates.
Break Fees Explained
Break fees (also called early redemption charges) apply when you exit a fixed rate mortgage before the term ends. The fee compensates the lender for losing the guaranteed interest income they expected.
How much you pay depends on two factors:
Interest rate movements: If rates have fallen since you fixed, you’ll pay a break fee. If rates have risen, the break fee is usually zero because the lender can re-lend your money at a higher rate.
Time remaining: The more time left on your fixed term, the larger the potential break fee, because the lender loses more expected interest.
The actual calculation is complex, but here’s a rough example:
You fixed at 4.0% for 5 years in 2023. It’s now 2026 and you want to switch. You have 2 years remaining on your fixed term and €250,000 outstanding. Current 2-year rates are 3.5%. The lender calculates they’ll lose 0.5% interest for 2 years on €250,000, which equals roughly €2,500. That’s your break fee.
But if current rates were 4.5%, there’s no break fee because the lender can re-lend at a higher rate than you were paying.
Each Irish lender calculates break fees slightly differently:
- AIB: Uses wholesale funding rates, typically results in higher fees
- Bank of Ireland: Similar methodology to AIB
- Permanent TSB: Generally lower break fees, more borrower-friendly calculation
- Avant Money: No break fees on any product (highly unusual)
- EBS: Moderate break fees, standard calculation
Always request a break fee estimate in writing before making any decisions. Some lenders provide online calculators.
Who Should Choose a Fixed Rate
Fixed rates suit you if:
You want payment certainty: You’re on a tight budget and can’t absorb a €200+ monthly increase if rates rise. This is especially common for first-time buyers stretching to afford their first home.
You’re risk-averse: You’ll sleep better knowing exactly what you’ll pay for the next 3-5 years, even if that means potentially paying more than a variable rate.
You plan to stay put: You’re not planning to move house, pay off the mortgage early, or significantly overpay in the next few years. Break fees won’t be an issue.
You think rates will stay flat or rise: If you believe the ECB won’t cut rates much further from here, locking in 3.5% today protects you from future increases.
You’re a first-time buyer: Most first-time buyers in Ireland choose fixed rates because budgeting certainty matters more than potential savings, and they’re unlikely to move within 3-5 years.
Fixed rates are particularly popular right now because they’re actually cheaper than variables. You’re getting certainty and a better rate — it’s rare to get both.
Who Should Choose a Variable Rate
Variable rates suit you if:
You value flexibility: You might move house, inherit money, get a bonus, or otherwise want the option to make large overpayments or pay off the mortgage entirely without penalty.
You expect rates to fall significantly: If you believe ECB rates will drop below 2% within the next year, a variable rate lets you benefit immediately. Fixed rate holders have to wait until their term expires.
You’re remortgaging soon anyway: If you’re planning to switch lenders in 6-12 months for a better deal, starting on a variable rate gives you flexibility without break fee concerns.
You’re on a legacy tracker: If you have an old tracker mortgage at ECB + 0.75% or similar, you should almost never give it up. These are extraordinarily valuable as ECB rates fall.
You’re wealthy enough to absorb rate rises: If a 1% rate increase would add €200/month but that’s manageable for your income, variable rates give you flexibility to capitalise on rate cuts.
Variable rates are less popular right now because they cost more than fixed rates, which eliminates the traditional reason to choose them.
How to Decide: A Practical Framework
Work through these questions:
1. What’s your risk tolerance? If a €150-200 monthly increase would cause genuine hardship, choose fixed. If you can absorb that without difficulty, variable becomes viable.
2. How long will you keep this mortgage? Staying 5+ years: fixed makes sense. Moving in 1-2 years: variable avoids break fees. Unsure: lean fixed for certainty.
3. What’s your view on ECB rates? Think rates will fall sharply: variable lets you benefit. Think they’ll rise or stay flat: fixed protects you. No strong view: fixed gives certainty.
4. What’s the rate difference? Right now fixed is 0.7% cheaper on average. That’s unusual. If variable were cheaper, you’d need to weigh the savings against the risk.
5. Do you plan to overpay? Most Irish fixed rate mortgages allow 10% overpayment per year without penalty. If you’ll regularly overpay more than 10%, variable might suit better.
6. What happens in 3-5 years? Will you remember to switch when your fixed term expires, or will you drift onto expensive SVR? If you’re organised, fixed is fine. If not, variable means no action required to avoid rate jumps.
For most Irish borrowers in late 2026, the answer is straightforward: choose a 3-year or 5-year fixed rate. You’re getting certainty plus a cheaper rate, which is the best of both worlds.
Switching Between Fixed and Variable
You can switch from variable to fixed at any time without penalty. You can do this either:
- With your existing lender (rate switch)
- By switching to a new lender entirely
Switching from fixed to variable or fixed to another fixed rate usually incurs a break fee unless:
- Rates have risen since you fixed (making the break fee zero)
- You’re switching to a higher rate product with the same lender
- Your lender is one of the few (like Avant) that doesn’t charge break fees
The process takes 6-12 weeks if switching lenders, or 2-4 weeks if just changing rates with your current lender.
What Happens When Your Fixed Rate Ends
About three months before your fixed rate expires, your lender should contact you with options. In practice, many don’t bother or send one generic letter you’ll probably miss.
If you do nothing, you automatically roll onto standard variable rate. For someone on a 3.5% fixed rate, this could mean jumping to 4.2% overnight. On a €300,000 mortgage, that’s an extra €175/month.
Your options at the end of a fixed term:
- Fix again with the same lender: Usually the easiest but rarely the cheapest option
- Switch to a new lender: Takes longer but often saves 0.3-0.5% in rate
- Move to variable: Only if you’re planning to pay off the mortgage soon or expect significant rate cuts
Set a calendar reminder for 4-5 months before your fixed rate expires. This gives you time to get quotes, compare rates, and switch lenders if needed before you roll onto expensive SVR.
The Special Case of Tracker Mortgages
If you have a tracker mortgage from before 2008, you’re in an enviable position. Many of these mortgages track at ECB + 0.75% to ECB + 1.25%, meaning you’re paying roughly 3.0-3.5% right now as the ECB rate sits at 2.75%.
Never give up a tracker mortgage unless absolutely forced to. They’re no longer available to new customers and represent extraordinary value, especially if ECB rates continue falling toward 2%.
Even if you could switch to a fixed rate at 3.1%, you’d lose the tracker forever. When your fixed rate ends, you’d roll onto SVR at 4.2%. Meanwhile, tracker holders continue benefiting from every ECB rate cut.
The only exception is if you have a high-margin tracker (ECB + 2.0% or more). In that case, calculate whether switching to a low fixed rate and then to a competitive variable in 3-5 years would save money overall.
Common Mistakes to Avoid
Ignoring break fees: Always request a written break fee estimate before deciding to switch or pay off a fixed rate mortgage early. Verbal estimates or online calculators can be inaccurate.
Assuming SVR is competitive: Standard variable rates are almost never the best deal. Staying on SVR after your fixed rate expires typically costs €2,000-4,000 extra per year unnecessarily.
Choosing the wrong fixed term: Shorter fixed terms (1-2 years) cost more right now but give you flexibility sooner. Longer terms (7-10 years) lock you in for a very long time and cost more if you need to break. For most people, 3-5 years is the sweet spot.
Not shopping around: Rate differences of 0.5% are common between best and worst lenders. On a €300,000 mortgage, that’s €1,500/year or €7,500 over 5 years.
Forgetting to switch: At least 30% of Irish mortgage holders are on expensive standard variable rates simply because they never got around to switching. Set reminders and treat mortgage switching like a part-time job every 3-5 years.
The Bottom Line
For most Irish borrowers in October 2026, a 3-year or 5-year fixed rate mortgage is the
