Remortgaging Explained: A Simple Guide to Switching Your Mortgage Deal

Is your fixed-rate deal coming to an end? Are you hearing about lower rates and wondering if you're missing out? You might be thinking about remortgaging. For many homeowners in the UK, it's one of the smartest financial moves you can make.

But what does it actually involve? Is it right for everyone? At Rock Finance, we believe in clear, straightforward advice. This guide will break down everything you need to know about remortgaging, from the core 'what' and 'why' to the step-by-step 'how'.

What is Remortgaging?

Simply put, remortgaging means switching your existing mortgage to a new deal, either with your current lender or a completely different one. You're not moving house—you're just moving your mortgage.

Most people get a mortgage on a 2, 3, or 5-year fixed or tracker deal. When that initial term ends, you're automatically moved onto your lender's Standard Variable Rate (SVR). The SVR is almost always more expensive. Remortgaging is the process of finding a new, better deal before this happens.

Why Remortgage? The Good Sides

People choose to remortgage for several powerful reasons:

  1. To Save Money: This is the #1 reason. Securing a new deal with a lower interest rate can slash your monthly payments and save you thousands over the term.
  2. To Release Equity: Your home may have increased in value. Remortgaging can allow you to borrow more (based on your home's new value) to release a lump sum of cash for home improvements, a new car, debt consolidation, or other major expenses.
  3. To Get Different Features: You might want to switch from a variable to a fixed rate for security, or find a deal with more flexible overpayment options.
  4. To Pay Off Your Mortgage Sooner: By securing a lower rate, more of your monthly payment goes toward the capital, helping you clear your debt faster.

The Other Side: Potential Downsides & Costs

Remortgaging isn't free, and it's not always the right choice. It's crucial to weigh up the costs:

  1. Early Repayment Charges (ERCs): If you leave your current deal before the term ends, you'll likely face a hefty fee, often a percentage of your outstanding loan.
  2. Arrangement/Product Fees: The new lender will charge a fee for their new mortgage product.
  3. Legal & Valuation Fees: You'll typically need to pay for a solicitor and a property valuation for the new lender.
  4. Stress and Paperwork: It involves an application process almost as thorough as your original mortgage.

The Golden Rule: Your savings from the new, lower rate must significantly outweigh all these combined costs for remortgaging to be worthwhile.

How Does Remortgaging Work? The Step-by-Step Process

  1. Review & Research (3-4 months before your deal ends): Check your current mortgage statement for your ERC end date and current rate. Start looking at new deals on the market or speak to an adviser.
  2. Get Advice & An Agreement in Principle: A whole-of-market broker, like Rock Finance, can compare thousands of deals you can't see online. They'll get you an Agreement in Principle (AIP) to confirm what you could borrow.
  3. Formal Application: Once you choose a deal, you submit a full application. Your adviser will handle this with the lender.
  4. Property Valuation & Legal Work: The new lender will value your home. You'll appoint a solicitor to handle the legal transfer of the mortgage.
  5. Offer & Completion: The lender issues a formal mortgage offer. Your solicitor coordinates with your old and new lenders to "redeem" the old mortgage and start the new one on your chosen date.

Does Remortgaging Affect My Credit Score?

This is a common concern. The short answer is yes, but usually in a minor and temporary way.

  1. When you apply for a new deal, the lender will perform a "hard search" on your credit file, which leaves a footprint and can cause a small, temporary dip.
  2. However, this is normal for any credit application. The impact is minimal if you are only applying for one new mortgage.
  3. Crucially, staying on a costly SVR and struggling with payments would damage your credit score far more in the long run. A successful remortgage that lowers your bills demonstrates good financial management.

Common Mortgage Questions

Yes, it is possible, but your options will be different. You may not qualify for the very best rates, and you may need to use a specialist lender. An adviser can help navigate this market.

Typically, it takes between 4 to 8 weeks from application to completion, provided there are no complications with your paperwork or the property valuation.

Remortgaging involves switching your mortgage to a new deal with a different lender. If you’re thinking of switching with us, we offer a switch and save feature to cover the cost of surveys and internal solicitor fees and help you get a better rate or release equity.

Your current lender may offer you a "product transfer," which is often simpler and cheaper (with no valuation or legal fees). However, their rate might not be as competitive as what's available on the open market. Always compare both options.
