Remortgaging Explained: When and How to Do It

Remortgaging isn't complicated, but it does require a bit of planning and the right timing - and the difference between a good remortgage and a poor one can be thousands of pounds.

You've got a mortgage. You're paying it every month. But did you know that if you're not actively shopping around when your deal ends, you might be paying far more than you need to? Remortgaging is the process of switching your mortgage to a new deal, usually with better terms or a lower rate. For most homeowners, it's one of the most impactful financial decisions you can make - yet many people drift into their lender's Standard Variable Rate (SVR) without realising the cost.

What Is Remortgaging?

Remortgaging means switching from one mortgage deal to another. You're not borrowing more money or moving house - you're simply refinancing your existing mortgage with new terms. That might be a new rate, a new lender, or both.

When you remortgage, your new lender pays off your old mortgage in full. From that point on, you make monthly payments to the new lender instead. It's a bit like switching energy suppliers - the product is essentially the same, but the terms change.

You might remortgage to get a lower interest rate, reduce your monthly payments, switch from a variable rate to a fixed one, or access better features in your mortgage. Sometimes the best financial decision is simply paying attention when your current deal ends.

Practical takeaway: remortgaging is switching to a new mortgage deal to get better terms.

When Does Your Mortgage Deal End?

Your mortgage isn't one long continuous agreement. It's made up of individual "deals" - usually fixed-rate periods of 2, 3, 5, or sometimes 10 years. When your current deal expires, you need to move onto a new one.

You should check your mortgage documents or contact your lender to find the exact date your current deal ends. Mark this date in your calendar now. Your lender should contact you automatically as the date approaches, but don't rely on it - they have no incentive to remind you that you could get a better deal elsewhere.

Most lenders allow you to remortgage from around 3-4 months before your current deal ends. That's your window to shop around for new rates without penalty. If you remortgage within that window, you can lock in a new deal to start on the day your current one ends, so there's no gap.

Practical takeaway: find your deal end date, then start shopping for new rates 3-4 months before.

The SVR Trap: Why You Don't Want to Drift

Here's what happens if you don't remortgage before your deal ends: your lender automatically moves you to their Standard Variable Rate, or SVR. This is essentially their way of saying "we've finished with our special offer, so now you pay whatever rate we feel like charging."

SVR is almost always significantly higher than the available fixed rates in the market. Lenders know they have you captive - switching requires action and paperwork, and many people don't bother. They're banking on inertia.

Imagine you've been on a fixed rate of 3%. Your deal ends and you drift onto SVR at 5.5%. On a £300,000 mortgage, that's an extra £7,500 a year in interest. Every month you delay is money leaking out of your account. Even a difference of 0.5% per year compounds significantly over time.

Some people worry about remortgaging costs, so they stay on SVR to "save money." This rarely makes sense. The extra cost of a remortgage usually pays for itself within a few months if you're moving to a meaningfully lower rate.

Practical takeaway: avoid SVR at all costs. Even a small rate reduction saves you thousands over the course of your mortgage.

Should You Use a Broker or Go Direct?

When remortgaging, you have two paths: work with a mortgage broker, or approach your lender or another lender directly.

Mortgage brokers have access to deals that aren't available directly to the public. They also handle the paperwork and liaise with lenders on your behalf, which saves you time and hassle. Some brokers charge a fee, but many are paid by the lender (through a commission), so it costs you nothing extra.

Going direct to a lender or using comparison websites means you see advertised rates immediately. But you might miss specialist deals or end up paying more. Direct applications also mean more paperwork for you to manage.

For most people, a broker is worth it - especially if they're fee-free. They can access a wider range of options and often negotiate better terms. Make sure they're FCA-regulated (you can check on the FCA's website) and ask about their fees upfront.

Practical takeaway: use a fee-free FCA-regulated broker to access a wider range of deals and save time.

Understanding the Costs of Remortgaging

Remortgaging isn't free. Understanding the costs helps you decide whether it's worth it and factor them into your decision.

Common remortgage costs include:

  • Arrangement fees (charged by the new lender): typically £500-£2,000

  • Valuation fee (if needed): £100-£500

  • Legal fees: usually £150-£300

  • Early repayment charge (from your old lender): only if you're in a fixed-rate deal with an ERC clause

  • Broker fees: usually included in the arrangement fee or paid by the lender

Some of these you can reduce or avoid. For example, many lenders now offer free valuations, and you can shop around for legal fees. The biggest variable is the early repayment charge - if you're not at the end of a fixed-rate deal, your old lender might charge you a penalty for leaving early.

Here's the key: work out whether the savings from a lower rate will cover these costs, and how long that payback period will be. If you're saving £100 a month with a £1,500 cost, you'll break even in 15 months. Given that most remortgages are done at the end of a deal (with no early repayment charge), the payback is often much faster.

Practical takeaway: calculate the total cost and compare it to your monthly savings. Most remortgages pay for themselves within a few months.

The Remortgaging Process, Step by Step

If you decide to remortgage, here's what happens:

1. Find a deal - Either through a broker or direct comparison. This takes a few days.

2. Apply - Complete the application, including income and employment checks. A few days to a week.

3. Property valuation - The new lender may want to value your property. This can be done via a desktop valuation (checking online data) or a surveyor's visit. A few days to two weeks.

4. Legal work - Your solicitor or the lender's solicitor handles the conveyancing. This is mostly paperwork. One to two weeks.

5. Completion - The new mortgage is finalised. Your old mortgage is paid off and your new one begins. Usually happens on a specific date you've agreed to.

The whole process typically takes 4-8 weeks from application to completion. The earlier you start, the less rushed you'll feel and the better your chances of completing on time.

Practical takeaway: start the remortgage process 3-4 months before your current deal ends to avoid any last-minute stress.

Fixed vs Variable Rates When Remortgaging

When you remortgage, you'll see both fixed-rate and variable-rate options. Understanding the difference helps you choose what suits your situation.

Fixed rates lock in a specific interest rate for the length of your deal - typically 2, 3, 5, or 10 years. Your monthly payments stay exactly the same for that entire period, regardless of what interest rates do in the wider economy. This provides certainty and protection if rates rise.

Variable rates fluctuate - they might be tied to the Bank of England base rate, or they might be set at the lender's discretion (like SVR). Your payments could go up or down, making budgeting less predictable.

Most homeowners choose fixed rates for the stability. When interest rates are volatile (as they have been recently), knowing exactly what you'll pay removes one source of stress. Variable rates can occasionally be cheaper, but that advantage evaporates if rates rise.

Practical takeaway: fixed-rate mortgages are generally safer and more popular. Choose a fixed term that matches your circumstances.

Should You Remortgage Early or Wait?

If you're still in a fixed-rate deal but interested rates have dropped significantly, you might wonder whether early remortgage makes sense. Usually, it doesn't - unless the savings are truly substantial.

Why? Early repayment charges. If your current deal has an ERC (early repayment charge), the cost might be £2,000 or more. That eats into your savings. Only remortgage early if your savings over the remaining time on your current deal would exceed both the ERC and all the remortgage costs. Generally, that requires a rate drop of 1% or more.

The safer strategy: wait until your deal naturally ends, then remortgage.

Practical takeaway: avoid remortgaging before your deal ends unless you're saving more than the ERC and associated costs.
