The lenders with the largest cashback offers often charge higher interest rates, which can wipe out the upfront benefit over a 25-year term. This page is built to help you weigh the real numbers, not the marketing.
Enter your loan amount and circumstances to see what each lender will pay.
Figures are illustrative only and assume eligibility. PTSB monthly cashback is calculated from today to 31 Dec 2030. BOI/EBS Cashback Plus assumes mortgage held for 5+ years. Always speak to an authorised broker before deciding.

Sometimes — but not always. Lenders with the biggest cashback offers (BOI, EBS, Haven, PTSB) often charge higher rates than the cheapest in market (typically AIB and Avant). Over 25 years, paying an extra 0.30% on a €300,000 mortgage costs over €15,000 in extra interest — easily wiping out a €5,000 cheque.
Rule of thumb: if you can get a comparable rate and cashback, take it. If you have to pay 0.20% or more for the cashback, do the maths — it usually doesn’t add up.
No. Mortgage cashback is treated as a discount on the cost of credit, not income, so it is entirely tax-free in Ireland. There’s no income tax, no DIRT, and nothing to declare on your Form 11.
Yes. Under the EU Mortgage Credit Directive, lenders cannot claw back cashback if you switch away later. However, most lenders impose minimum holding periods: PTSB requires 2+ years with your previous lender; EBS, Haven and BOI all require 1+ year.
PTSB is the only Irish lender offering monthly cashback on top of a drawdown lump sum: 2% at drawdown plus 2% off every monthly repayment until 31 December 2030, paid into a PTSB Explore Account (€8/month fee).
Yes, but options are limited. Bank of Ireland’s flat 2% Cashback offer is the only mainstream offer openly available on buy-to-let, equity release and top-up mortgages.
