Remortgaging in 2026: When to Do It and How to Find the Best Deal

What Is Remortgaging — and Why Does It Matter in 2026?

Remortgaging simply means switching your existing mortgage to a new deal — either with your current lender or a different one — without moving home. It sounds straightforward, but done at the right moment it can save you thousands of pounds. Done at the wrong moment, it can cost you just as much in fees and penalties.

In 2026, remortgaging is particularly relevant. A large wave of homeowners who fixed their rates in 2021 and 2022 — when the Bank of England base rate was still near historic lows — have already rolled off those deals or are approaching the end of their fixed terms. Many are facing a significant jump in monthly payments. Understanding your options before that happens is not a luxury; it’s essential financial housekeeping.

When Should You Start Looking?

The golden rule is: start six months before your current deal ends. Most mortgage offers are valid for three to six months, so beginning your search early means you can lock in a rate now but complete the switch when your current deal expires — avoiding any early repayment charges (ERCs).

Tip: Check your mortgage statement or call your lender to find out your exact deal end date and whether any ERCs apply. These charges can be as high as 5% of your outstanding balance in the early years of a fix.

If you’re already on your lender’s Standard Variable Rate (SVR), you’re almost certainly paying too much. SVRs in 2026 typically sit between 7% and 8.5%, compared to competitive two- or five-year fixes that may be available significantly lower. Every month you wait on an SVR is money left on the table.

Fixed Rate, Tracker, or Variable? Know Your Options

Before comparing deals, you need to understand what you’re comparing:

• Fixed rate mortgage — your interest rate stays the same for a set period (typically two, three, or five years). Ideal if you want certainty over your monthly outgoings.
• Tracker mortgage — follows the Bank of England base rate plus a set percentage. Your payments can go up or down each month.
• Discount variable rate — a discount off the lender’s SVR for a set period. Lower initially, but less predictable than a fix.

For most remortgagers in 2026, a two- or five-year fixed rate remains the most popular choice. A two-year fix gives flexibility if you expect rates to fall further; a five-year fix offers stability if you’re risk-averse or budgeting carefully.

How to Find the Best Remortgage Deal

Step one: Know your loan-to-value (LTV). Your LTV is the size of your mortgage as a percentage of your property’s value. The lower your LTV, the better the rates available. For example, if your home is worth £300,000 and you owe £180,000, your LTV is 60% — which puts you in a competitive bracket with most lenders.

Step two: Use a whole-of-market broker. A good mortgage broker searches thousands of deals, including some not available directly to the public. They are regulated by the Financial Conduct Authority (FCA) and must recommend a product that suits your circumstances. Many charge a flat fee; others earn commission from lenders. Always ask upfront.

Step three: Don’t ignore the total cost, not just the headline rate. A mortgage with a 4.2% rate and a £1,499 arrangement fee may cost more overall than one at 4.5% with no fee — especially on a smaller mortgage or shorter term. Use a mortgage calculator to compare the full cost over the deal period.

Step four: Check cashback and incentive deals. Some lenders offer free valuations, free legal work, or cashback on remortgaging. These can offset switching costs, particularly if your current lender doesn’t cover those fees.

Real example: A homeowner with £200,000 outstanding on a 25-year mortgage, moving from an SVR of 7.9% to a five-year fix at 4.6%, could reduce their monthly payment by around £380 — saving over £22,000 across the fixed term.

What Are the Costs Involved?

Remortgaging isn’t free, but the costs are usually manageable:

• Early repayment charge (ERC) — only if you leave before your deal ends. Can be substantial.
• Arrangement or product fee — typically £500–£1,500, sometimes added to the mortgage (though this means paying interest on it).
• Valuation fee — many lenders offer a free basic valuation for remortgages.
• Legal/conveyancing fees — a solicitor is required to handle the legal transfer. Some lenders include free legal work as a remortgage incentive.
• Broker fee — if applicable, usually £300–£600 for a reputable adviser.

Note: unlike buying a new property, remortgaging does not trigger stamp duty.

When Remortgaging Might Not Be the Right Move

Remortgaging isn’t always the answer:

• If you’re close to the end of your mortgage term, the savings may not justify the costs.
• If your property value has fallen, your LTV may be higher than expected, limiting your access to competitive deals.
• If you have significant ERCs to pay, it may be worth waiting.
• If your financial circumstances have changed — a reduction in income, for example — you may find it harder to pass affordability checks with a new lender. In that case, a product transfer (switching to a new deal with your existing lender) may be easier and require no new affordability assessment.

The Bottom Line

Remortgaging in 2026 is one of the most impactful financial moves available to UK homeowners. Start early, understand your LTV, compare the total cost of deals rather than the headline rate alone, and use a regulated broker to navigate the full market. The effort involved is modest compared to the potential savings — which, for many households, can run into hundreds of pounds every single month.
