5 Mortgage Switching Mistakes That Cost Thousands

Switching your mortgage can save €20,000+. But these five common mistakes reduce or eliminate the savings entirely. Avoid them and you'll keep every cent.

Mistake 1: Forgetting Legal Fees

Switching involves solicitor fees of €1,500–€2,500. Many lenders offer a legal fee contribution (€1,200–€1,500), but you need to factor in the net cost. If switching saves €130/month but costs €1,000 net in legal fees, you break even in 8 months — still worth it, but don't ignore it.

Mistake 2: Triggering Cashback Clawback

If your current lender gave you cashback (e.g., 2% of mortgage = €6,000), switching before the clawback period ends (typically 3–5 years) means repaying some or all of it. Check your mortgage conditions before applying elsewhere.

Mistake 3: Switching Just Before Your Fix Ends

If you're in a fixed rate that expires in 3–6 months, you'll pay a break fee to leave early. It's often better to wait until the fix ends, then switch from the variable rate (no break fee). Exception: if rates are rising fast, locking in now might justify the fee.

Mistake 4: Not Checking Green Mortgage Eligibility

If your home has BER B3 or better, you qualify for green mortgage rates that are 0.1–0.3% cheaper. On a €280k mortgage, that's an extra €5,000–€12,000 saved over the term. Get your BER checked before you apply. Book at Homerating.ie

Mistake 5: Accepting the First Offer

Compare every lender. A 0.15% difference between two switcher products seems tiny, but on €280k over 23 years it's €6,000. Use our Mortgage Comparison Calculator to see exact differences.
