An Irish homeowner comparing a switch should include the costs and conditions of moving lender. A headline rate or cashback offer alone cannot establish whether the transaction produces a net saving.
The structure behind the offer
An Irish switching decision should use actual exit and entry costs. Separate promotional payments from continuing savings and check their conditions.
The decision that deserves the closest review
Compare legal, valuation and any fixed-rate break costs with the expected saving. Check promotional conditions directly and model costs over the intended period. Use the CCPC switching guidance to organise the enquiry and verify each lender’s actual offer.
Rate, fees and the cost over the chosen period
Compare offers using the same borrowing amount, valuation assumption and intended deal period. Show upfront charges and any fees added to the loan. Where terms differ, compare the remaining balance as well as payments, so a lower instalment is not mistaken for a lower total cost.
| Comparison item | Question to resolve |
|---|---|
| Existing-loan exit costs | What costs apply to leaving the current lender? |
| New legal and valuation charges | Which cashback conditions remain? |
| Promotional conditions and expected saving period | When does the switch recover its transaction costs? |
Ask for the offer assumptions to be explained in writing. A calculator or initial illustration should be kept separate from an underwritten offer and completion conditions.
A hypothetical example
A homeowner receives cashback but incurs switching expenses. It separates the one-off payment from continuing interest savings and checks whether the combined benefit exceeds the costs.
Documents and assumptions to organise
Organise borrower identity, income or trading information, existing borrowing and the property documents relevant to the enquiry. Show where the deposit and transaction cash come from. Ask the lender or broker for the precise evidence list and identify outstanding legal or valuation conditions.
Calculate the Irish switch using net costs and dates
Collect the existing mortgage details, any exit charge and the new offer’s expenses. Identify legal, valuation and other payments with their expected dates. If cashback is proposed, record its conditions and timing separately so the decision does not count it as an unconditional immediate saving.
Compare payments and remaining balances over the same planned period, including a possible later switch. Ask the provider or adviser which steps remain before completion. A break-even calculation is only as useful as its assumptions about fees, rates and how long the borrower keeps the arrangement.
Use current Irish lender terms and the borrower’s own transaction figures for the final comparison.
A mistake to avoid
Treating the largest cashback amount as proof of the lowest overall mortgage cost.
Completion, ongoing commitments and the next decision
List the conditions that remain before funds can be released and allow for realistic legal and valuation timing. After completion, record payments, review dates and any limits on changes to the property or borrowing. Keep a plan for the next deal expiry rather than treating the first offer as a permanent arrangement.
Questions before choosing
Does a switch always reduce repayments?
That depends on balance, term and offer; compare illustrations with consistent assumptions.
Should cashback determine which Irish offer is cheapest?
Compare it with the continuing payments and transaction costs. Check conditions and the chosen holding period before treating a promotional payment as the deciding saving.
