Switching Lender: The Legal Side of Moving Your Mortgage

Rate switches, full switches, cashback offers — and why one of them needs a solicitor and the other does not.

Irish mortgage holders can save meaningful money by switching, and lenders compete hard for switchers with rate discounts and cashback offers. But the word switch covers two very different things. An internal rate switch — moving to a different rate with your existing lender — is a paperwork exercise with the bank and needs no conveyancing. A full switch to a new lender is a remortgage: a legal transaction in which the new bank takes a first legal charge over your home and the old bank's charge is released.

This page covers the full switch: what the legal work is, what the Central Bank's switching rules do for you, and how cashback offers interact with the costs.

Rate switch vs full switch

If your goal is simply a lower rate and your current lender offers one, an internal rate switch is the cheapest and fastest option — typically a form, sometimes an up-to-date valuation, and no solicitor. Always price this option first, because it is the benchmark a full switch has to beat.

A full switch makes sense when another lender's rate, cashback or product features beat what your own bank will offer you, by enough to cover the switching costs. Our Remortgage Savings Calculator lets you test that in two minutes: it compares rates, adds your switching costs, and shows the month in which the switch pays for itself.

What the Central Bank switching rules give you

Since 2019 the Consumer Protection Code has contained specific mortgage switching provisions. Lenders must tell existing customers about cheaper options in certain circumstances, must give switchers clear information on the impact of moving, and must process completed switching applications within defined timeframes. Your current lender must also provide the information a switcher needs — including redemption figures — within set periods.

These rules make the banking side of a switch more predictable than it once was. The legal side — deeds, title, undertakings, redemption and registration — runs on the same conveyancing machinery as any remortgage, and that is where preparation matters most.

Cashback offers and what they really cover

Several lenders offer cashback on drawdown — commonly a percentage of the loan or a flat sum — aimed squarely at covering a switcher's costs. Since legal fees and outlays for a straightforward remortgage usually come in below typical cashback amounts, many switchers complete the move cash-positive before the interest savings even begin.

Read the conditions: cashback can come with clawback periods if you switch away again quickly, and the best cashback offer is not always the best loan. The comparison that matters is total cost over your realistic time horizon, not the headline sweetener. That is a financial decision for you and, if you use one, your broker — our role is to make the legal side fast and clean whichever lender you choose.

Fixed rates and break fees

If you are currently on a fixed rate, ask your lender for a break fee quotation before committing to a switch. Under the European Union (Consumer Mortgage Credit Agreements) Regulations 2016, early redemption charges on fixed rates are limited to the lender's actual funding loss, calculated on a prescribed basis — which means the fee depends on interbank rates and can be large, small or zero depending on when you break.

Break fee quotations are only valid for a short period because the underlying rates move. Time the request so the figure is fresh when you decide, and again when you draw down.

The switcher's legal checklist

A full switch runs through the standard remortgage process. The items below are the ones a switcher can usefully get moving on day one:

Instruct your solicitor as soon as you apply, not when the loan offer issues — the deeds request to your old lender can start early
Get your break fee quotation if you are on a fixed rate
Start mortgage protection and home insurance arrangements immediately; assignments and letters of interest take time
Confirm your Local Property Tax is up to date and accessible online
Tell your solicitor about any extensions, attic conversions or garage conversions — planning and compliance paperwork is the most common title snag

Frequently asked questions

Do I need a solicitor for a rate switch with my own bank?

Generally no. An internal rate switch does not change the lender or the charge on your property, so no conveyancing is involved. A switch to a different lender always requires a solicitor.

How much of the switching cost does cashback cover?

Often all of it. Typical legal fees and outlays on a straightforward remortgage are usually less than the cashback offered by lenders running such offers. Compare the whole loan, though — cashback is only one component of cost.

Can I switch while on a fixed rate?

Yes, but an early redemption charge may apply. The fee is capped at the lender's actual funding loss under the 2016 Mortgage Credit Regulations and can be zero when market rates have risen since you fixed. Always get a written quotation first.

How long does a switch take?

A clean switch commonly completes within a small number of months, driven mainly by how quickly the old lender produces deeds and redemption figures and how quickly the loan offer conditions are satisfied. See our remortgage timeline guide for the full breakdown.

Will the new lender revalue my house?

Yes — the new lender requires a valuation from its panel, at your cost, and the loan-to-value band the valuation puts you in can affect the rate you are offered.
