Remortgaging at the right moment can save you thousands; remortgaging at the wrong moment, or not at all, can cost just as much. Here are the five situations where it pays to act, the situations where it does not, and the timeline that makes the whole thing painless.
1. Your current deal is ending
This is the big one. When your fixed or discounted deal ends, your lender moves you onto its Standard Variable Rate (SVR), and SVRs are almost always significantly more expensive than the deals available to you.
An illustrative example: on a £150,000 repayment mortgage with 20 years remaining, the difference between an SVR of 7.5% and a new deal at 4.5% is roughly £270 a month, over £3,200 a year. The exact figures depend on your balance, term and the rates available when you switch, but the size of the gap is why this matters.
The key is to start early: you can usually lock in a new deal three to six months before your current one ends, and we recommend reviewing your options six months out. If rates fall between locking in and completing, you can often switch to the better deal.
2. You are already on the SVR
If your deal ended a while ago and you never switched, you are very likely overpaying every month. The good news: there is no early repayment charge to leave an SVR, so you can remortgage immediately. For most people in this position, the only question worth asking is "how quickly can I move?".
3. Your home has risen in value
Lenders price mortgages in loan-to-value (LTV) bands, typically at 90%, 85%, 80%, 75% and 60%. If your property has gained value since you bought, or you have paid down a decent chunk of the balance, you may have dropped into a lower band without realising, and the rates in that band are better. Northern Ireland prices have risen meaningfully over recent years, so this catches out more local homeowners than you might think, in a good way.
4. Rates have dropped since you fixed
If you fixed when rates were higher, switching early can be worth it, but this is the one scenario where the maths needs real care. Breaking a fixed deal usually triggers an early repayment charge, often a percentage of your outstanding balance. Sometimes the saving from a lower rate outweighs the charge; often it does not. This is a calculation we run for clients all the time, and we will tell you plainly if staying put is the better answer. Keeping an eye on current mortgage rates in Northern Ireland helps you judge when it is worth a closer look.
5. Your circumstances have changed
A remortgage is also the moment to restructure:
- Your income has risen and you want to shorten your term or overpay more freely.
- You want to release equity for home improvements or to consolidate more expensive borrowing (with care, since securing short-term debt against your home extends it over a longer period).
- Your current mortgage no longer fits, for example you want to move from interest-only towards repayment.
- Separation or divorce, where one partner buys the other out and the mortgage needs to be rewritten.
When NOT to remortgage
Honesty matters more than a transaction to us, so: remortgaging is often the wrong move when your outstanding balance is small (fees can outweigh savings), when a hefty early repayment charge wipes out the benefit, when your credit position has temporarily weakened, or when your current deal still has a long time to run and rates are not dramatically different. If any of those apply, we will say so.
Product transfer or full remortgage?
Staying with your current lender (a product transfer) is quick, involves little paperwork and sometimes no new affordability check. Moving to a new lender (a full remortgage) opens up the whole market and frequently better pricing, but takes longer. The right answer depends on your situation; we compare both side by side, including your current lender's retention deals, before recommending anything.
The six-month timeline
- Six months out: get a remortgage review booked. We check your current deal's end date, your LTV and the market.
- Three to six months out: secure a new offer. You are protected if rates rise and can usually still benefit if they fall.
- Completion: the new deal starts the day the old one ends. No SVR gap, no overlap.
