The Complete Guide to Remortgaging

If you’re approaching the end of your fixed-rate mortgage deal—or wondering whether you could secure a better rate—you’re in good company. Thousands of UK homeowners remortgage every year, often saving hundreds of pounds monthly in the process.

This guide covers everything you need to know about remortgaging, from deciding whether it’s right for you to completing the switch with confidence.

What Is Remortgaging and Why Consider It?

Remortgaging means replacing your current mortgage with a new one, either with your existing lender or a different one. Your home stays the same—only the mortgage product changes.

The most common reason to remortgage is securing a better interest rate. When your fixed-rate deal ends, you’ll typically move onto your lender’s standard variable rate (SVR), which is almost always significantly higher. Switching to a new deal can result in substantial savings.

Other reasons include releasing equity for home improvements, consolidating debts, or adapting to changed circumstances such as increased income or relationship changes.

When Should You Start Thinking About Remortgaging?

The ideal time to explore options is around six months before your current deal ends. Most mortgage offers remain valid for three to six months, giving you time to secure a new rate before rolling onto the SVR.

Key triggers to act include your fixed-rate ending soon, already being on the SVR, your property increasing significantly in value (potentially unlocking better rates), or your financial circumstances improving since your last application.

The Remortgage Process Step-by-Step

Understanding what’s involved removes uncertainty and helps you plan effectively.

Review your current position by checking your mortgage balance, remaining term, interest rate, and any early repayment charges that might apply.

Research your options by comparing deals directly, using comparison sites, or working with a whole-of-market broker who can search across all available lenders.

Apply for an agreement in principle, then submit your full application with supporting documents including payslips, bank statements, and ID.

The lender values your property and assesses your application before issuing a formal mortgage offer.

Legal work transfers the mortgage from your old lender to the new one—many deals include free legal services.

Completion day sees your new mortgage pay off the old one. The whole process typically takes four to eight weeks.

Understanding the Costs Involved

Remortgaging isn’t free, so factor in these potential costs when calculating whether switching makes sense.

Early repayment charges (ERCs) can be substantial if you leave your current deal early—always check before committing. Arrangement fees vary from nothing to over £1,000; a lower rate sometimes comes with higher fees. Valuation and legal fees are often included free with remortgage deals but can add £500 or more if not.

Calculate total costs against potential savings over your new deal period rather than focusing solely on the headline rate.

How Whole-of-Market Brokers Help

Many mortgage deals are only available through brokers, meaning you simply cannot access them directly. Working with a whole-of-market broker like Property Finance Hub gives you access to these exclusive deals alongside everything available directly—over 150 lenders in total.

Beyond access, brokers understand which lenders suit particular circumstances, manage the paperwork, and keep the process moving smoothly.

Tips for Maximising Your Savings

Start early—six months before your deal ends gives comfortable breathing room. Check your credit report for errors before applying. Gather documents in advance to speed up the process. Consider the full deal period when comparing costs, not just the rate. And if you’re unsure about anything, take professional advice—the stakes are too high for guesswork.

Frequently Asked Questions

How long does remortgaging take? Typically four to eight weeks from application to completion, though starting six months early gives you comfortable breathing room.

Can I remortgage if I’m self-employed? Yes—you’ll need SA302 tax calculations and accounts, usually covering at least two years. A broker familiar with self-employed applications can identify suitable lenders.

What’s the difference between remortgaging and a product transfer? A product transfer keeps you with your current lender on a new rate, with a simpler process. A full remortgage opens up the entire market but involves more thorough checks. Comparing both options ensures you get the best deal.

Is it worth remortgaging for a small rate reduction? It depends on the numbers. Calculate total savings over the deal period against all fees involved—sometimes modest rate improvements are worthwhile, sometimes the fees outweigh the savings.

Your home may be repossessed if you do not keep up repayments on a mortgage or other loan secured on it.
