Cashback Mortgage Offers: What to Check Before You Switch
5 February 2026 · Mary Molloy Solicitors
Cashback is the sweetener that built the Irish switching market: a percentage of the loan or a flat sum paid on drawdown, aimed at making the switch cost-free. Used well, it is exactly that. Used as the deciding factor, it can cost multiples of itself in interest.
What cashback is designed to do
Switching has real costs — legal fees, valuation, possibly a break fee. Cashback exists to neutralise them so cost stops being the objection. On standard cases the cashback exceeds the total costs, making the switch cash-positive on day one. That is a genuine benefit and there is nothing wrong with taking it.
The rate is still the main event
A lender offering rich cashback with a higher rate is lending you your own sweetener back with interest. The comparison that matters is total cost over your realistic horizon: interest at each candidate rate, minus cashback, plus costs. On a large balance, a modest rate difference outweighs a headline cashback within a few years.
Read the clawback and payment conditions
Check when the cashback is paid and to which account; whether a second tranche depends on staying a number of years; and whether the offer claws back if you redeem or switch away within a defined period. Clawback terms matter if your plan involves selling or switching again soon.
How it flows through the transaction
Cashback is normally paid by the lender directly to your account after drawdown — it does not pass through your solicitor and is separate from the loan funds that redeem your old mortgage. Budget to pay legal fees and outlays in the ordinary way, with the cashback restoring the position days later.
