Cashback mortgages sound attractive. Borrow €300,000, get €6,000 back straight away. That’s real money in your account when you’ve just emptied your savings for a deposit and stamp duty.
Bank of Ireland, Permanent TSB and EBS all offer cashback products in 2026, typically paying 2% of your mortgage amount. But these products consistently charge higher interest rates than their standard equivalents—usually 0.3–0.5% more.
The question isn’t whether cashback mortgages exist or how much you get back. It’s whether you’re actually better off taking one, or whether you’re paying thousands extra in interest for what amounts to an expensive short-term loan.
This guide runs the numbers properly, compares what Irish lenders currently offer, and shows you exactly when cashback makes financial sense (spoiler: rarely).
What Is a Cashback Mortgage?
A cashback mortgage pays you a percentage of your loan amount—typically 2% in the Irish market—shortly after drawdown. If you borrow €300,000, you receive €6,000. If you borrow €400,000, you get €8,000.
The money arrives in your account within weeks of closing. You can spend it however you like: furniture, renovations, paying back family who helped with the deposit, or just keeping it as an emergency fund.
The catch: cashback mortgages charge higher interest rates than equivalent standard mortgages from the same lender. You’re not getting free money. You’re accepting a worse rate in exchange for upfront cash.
Most cashback products also lock you in for 3–5 years. If you switch lender or repay early during this period, you must return the cashback, sometimes with interest.
Current Cashback Mortgage Offers in Ireland (September 2026)
Three mainstream Irish lenders offer cashback products. Here’s what they’re charging:
| Lender | Cashback Amount | Rate (3yr fixed) | Standard Rate (3yr fixed) | Rate Premium |
|---|---|---|---|---|
| Bank of Ireland | 2% | 4.25% | 3.80% | +0.45% |
| Permanent TSB | 2% | 4.30% | 3.85% | +0.45% |
| EBS | 2% | 4.20% | 3.75% | +0.45% |
All three charge roughly 0.45% more for cashback mortgages compared to their standard fixed rate products. This premium is consistent across different loan-to-value (LTV) ratios, though exact rates vary by LTV band and whether you’re a first-time buyer.
None of the major Irish lenders offer cashback on variable rate products. You must take a fixed rate, typically 3 or 5 years.
These figures are indicative for a typical 80% LTV first-time buyer mortgage. Your actual rate depends on your LTV, employment status, and whether you’re buying or switching.
The Real Cost: Running the Numbers
Let’s use a realistic example. You’re borrowing €300,000 over 30 years. You’re choosing between:
Option A: Standard 3-year fixed rate at 3.80%
Option B: Cashback mortgage at 4.25% with €6,000 upfront
Here’s what you actually pay:
Total Cost Over 3 Years
Standard mortgage (3.80%):
- Monthly repayment: €1,394
- Total paid over 3 years: €50,184
- Interest paid: €33,849
- Principal paid: €16,335
Cashback mortgage (4.25%):
- Monthly repayment: €1,476
- Total paid over 3 years: €53,136
- Interest paid: €36,986
- Principal paid: €16,150
- Less cashback received: -€6,000
- Net cost: €47,136
Over the initial 3-year fixed period, the cashback mortgage costs you €2,952 less than the standard product (€50,184 vs €47,136). The cashback wins.
But this assumes you switch lender immediately after 3 years, which most people don’t do.
Total Cost Over 5 Years
Assume you stay on the same rate for 5 years (or revert to a similar premium when your fixed period ends):
Standard mortgage (3.80%):
- Total paid over 5 years: €83,640
- Interest paid: €55,582
Cashback mortgage (4.25%):
- Total paid over 5 years: €88,560
- Interest paid: €60,962
- Less cashback: -€6,000
- Net cost: €82,560
You’re now only €1,080 better off with cashback over 5 years. The advantage is shrinking.
Total Cost Over 10 Years
Standard mortgage (3.80%):
- Total paid over 10 years: €167,280
- Interest paid: €105,864
Cashback mortgage (4.25%):
- Total paid over 10 years: €177,120
- Interest paid: €117,544
- Less cashback: -€6,000
- Net cost: €171,120
After 10 years, the cashback mortgage has cost you €3,840 more than the standard product. You’re now worse off.
The break-even point for a typical cashback mortgage is around 4–5 years. If you stay with the lender beyond that, you lose money compared to taking the lower rate from the start.
When Does Cashback Actually Make Sense?
Cashback mortgages work financially in specific circumstances:
1. You’re definitely switching in 3 years
If you plan to remortgage as soon as your fixed period ends—and you have the discipline to actually do it—cashback can save you money over that short window. Most borrowers say they’ll switch. Few actually do.
2. You desperately need cash now
You’ve scraped together your deposit but have nothing left for furniture, immediate repairs, or an emergency fund. Taking €6,000–€8,000 now might be worth paying extra interest if the alternative is high-interest credit card debt or personal loans.
3. You’re using the cashback strategically
If you invest the cashback immediately into overpaying your mortgage, you offset some of the higher interest cost. Put €6,000 straight onto your mortgage as an overpayment and you reduce your total interest bill. Most people don’t do this—they spend the money—but if you do, the numbers improve.
4. You value liquidity over total cost
Some borrowers prefer having cash available now even if it costs more long-term. This is a valid choice if you understand the trade-off. Money in your account today has utility. Just don’t pretend it’s financially optimal.
When Cashback Is a Bad Idea
You’re staying with the lender long-term
If you’re the type who doesn’t switch mortgages—many Irish borrowers still sit on standard variable rates years after their fixed period ends—cashback costs you money. You pay the rate premium for years while the upfront cash becomes a distant memory.
You’re close to a lower LTV band
If you’re at 82% LTV, you might be better off finding another €6,000 for your deposit to drop below 80% and access better rates, rather than taking cashback on a worse rate. The long-term interest saving from a lower LTV rate usually exceeds the cashback amount.
You don’t actually need the money
If your finances are comfortable and you’re taking cashback just because it’s offered, you’re making an expensive mistake. Take the lower rate instead.
You’re comparing different lenders
A cashback product from Bank of Ireland at 4.25% is almost always worse than a non-cashback product from Haven at 3.50%, even after accounting for the cashback. Always compare the total cost across lenders, not just within one lender’s product range.
Cashback Clawback Rules
All Irish cashback mortgages include clawback provisions. If you repay your mortgage within a set period—typically 3–5 years—you must return the cashback.
Bank of Ireland: 5-year clawback. Repay early and you return the full cashback amount.
Permanent TSB: 3-year clawback. If you switch or repay within 3 years, you repay the cashback plus interest at the mortgage rate.
EBS (owned by AIB): 5-year clawback, full repayment required.
Clawback applies if you switch lender, sell the property, or fully repay the mortgage. It doesn’t usually apply to overpayments within the allowed limits (typically 10% per year), but check your specific terms.
This means you can’t game the system by taking cashback, immediately switching for a better rate, and keeping the money. The clawback period is longer than the fixed rate period specifically to prevent this.
The Switching Problem
The cashback calculation assumes you switch lender after 3 years. In reality, Irish mortgage holders are terrible at switching.
Central Bank data shows that fewer than 1 in 10 borrowers switch lender when their fixed rate ends. Most just accept whatever rate their existing lender puts them on, even though switching could save €2,000–€3,000 per year.
If you’re not the type to actively manage your mortgage, don’t take cashback assuming you’ll be disciplined enough to switch later. You probably won’t be, and you’ll end up paying thousands extra in interest.
The borrowers who benefit most from cashback are exactly the borrowers who least need it: financially sophisticated people who actively manage their mortgages and will definitely switch at the optimal time.
Alternative Uses for Your Deposit Money
Instead of taking a cashback mortgage, consider whether you’re better off:
Keeping a smaller emergency fund and using more for your deposit
If you’re contributing less than the maximum deposit to stay liquid, and then taking cashback to rebuild liquidity, you’re doing it backwards. A larger deposit gets you a better LTV rate and saves more interest than cashback provides.
Borrowing from family instead
If family can lend you €5,000–€10,000 interest-free for furniture and settling-in costs, that’s better than paying 4.25% on a cashback mortgage for money you’ll spend on the same things.
Taking a 0% credit card for short-term expenses
Some expenses can go on a 0% purchase credit card and be paid off over 12–24 months. This is cheaper than a mortgage rate, even a good one.
Accepting you’ll furnish gradually
You don’t need to fully furnish and renovate in month one. Living with basics for 6–12 months while you save is cheaper than paying mortgage interest on cashback for 5+ years.
How Cashback Compares to Other Incentives
Irish lenders occasionally offer different incentives beyond cashback:
Free valuations: Worth €150–€200. Always accept if offered; it’s genuine value with no strings.
Legal fee contributions: Worth €1,500–€2,500 for first-time buyers. Better than cashback because it reduces your upfront costs without affecting your rate.
Rate discounts for 1 year: Sometimes lenders offer 0.5% off for year one. Run the numbers—this is often better than cashback because you’re not locked into a higher rate long-term.
Green mortgages: 0.25% discount for energy-efficient homes. Better than cashback; it’s a rate reduction, not a short-term payment.
If you’re offered both cashback and a rate discount, take the rate discount unless you have genuine short-term cash flow problems.
The Psychological Factor
Cashback mortgages are popular because humans are bad at valuing future costs versus immediate benefits. €6,000 in your account today feels real and tangible. Paying an extra €82 per month feels abstract and manageable.
This is exactly why lenders offer cashback products. They’re profitable for banks precisely because borrowers underestimate the long-term cost and overvalue the immediate payment.
If you find yourself attracted to cashback despite the numbers showing it costs more, you’re experiencing this bias. Recognising it doesn’t make it go away, but it should make you pause before choosing the more expensive option.
Tax Treatment
Cashback payments are not taxable income in Ireland. The Revenue Commissioners treat mortgage cashback as a discount on your loan, not as income. You don’t declare it on your tax return and you don’t pay income tax or USC on the amount received.
This is one of the few positives for cashback mortgages: the full 2% is yours to keep.
Should You Take a Cashback Mortgage?
For most Irish mortgage borrowers, cashback is poor value. You pay more in interest than you receive upfront, and you’re locked into a higher rate for years.
Take cashback only if:
- You have genuine short-term cash needs and no cheaper way to access money
- You’re absolutely certain you’ll switch lender when your fixed period ends
- You’re willing to immediately overpay the cashback amount onto your mortgage
- You value having liquid cash now over saving money long-term
Don’t take cashback if:
- You’re choosing it just because it’s offered
- You could access the same amount by slightly reducing your deposit or borrowing from family
- You’re unlikely to actively manage your mortgage and switch lender
- You’re comparing different lenders and ignoring better non-cashback rates elsewhere
The best approach: calculate the total cost of cashback versus standard rates over 5 years using your actual mortgage amount. If the cashback version costs more over 5 years—and it usually does—take the standard rate and find another way to cover short-term expenses.
Cashback mortgages aren’t scams, but they’re expensive short-term loans dressed up as incentives. Most borrowers are better off taking the lower rate from the start.
