Understanding Remortgaging

A comprehensive guide to switching your mortgage deal and potentially saving thousands of pounds.

What is Remortgaging?

Remortgaging means switching your existing mortgage to a new deal, either with your current lender (product transfer) or a different lender. It's one of the most effective ways to reduce your monthly payments and save money over the life of your mortgage.

Most people remortgage when their initial fixed-rate, tracker, or discount period ends and they revert to their lender's Standard Variable Rate (SVR), which is typically much higher than fixed-rate deals.

When Should You Remortgage?

1. Fixed Rate Period Ending (Most Common)

Your lender will typically write to you 3-6 months before your fixed term ends. This is the ideal time to start shopping for a new deal. If you don't remortgage, you'll move to the SVR, which can be 2-3% higher.

Example: Fixed rate at 3.5% ends → SVR at 6.0% = £347/month more on a £250,000 mortgage

2. Interest Rates Have Dropped

If market rates have fallen significantly since you took out your mortgage, remortgaging could save you money even during a fixed period (though early repayment charges may apply).

3. Improved Loan-to-Value (LTV)

If your property value has increased or you've paid down your mortgage, you'll have a better LTV ratio, giving you access to cheaper mortgage rates.

4. To Borrow More (Remortgage and Further Advance)

You can remortgage to release equity for home improvements, debt consolidation, or other purposes. This is often cheaper than personal loans or credit cards.

The Remortgaging Process

1

Review Your Current Mortgage (3-6 months before end date)

Check your outstanding balance, remaining term, current rate, and any early repayment charges.

2

Shop Around for Deals

Compare rates from multiple lenders, use comparison sites, or consult a mortgage broker who can access exclusive deals.

3

Apply for New Mortgage (Decision in Principle)

Submit your application with proof of income, identity, and address. Lender will value your property.

4

Mortgage Offer and Legal Work

Once approved, your solicitor will handle the legal transfer. This typically takes 4-8 weeks.

5

Completion

New mortgage starts, old mortgage is paid off. Start making payments to your new lender.

Benefits and Considerations

Benefits of Remortgaging

  • Save hundreds or thousands per year on interest
  • Lock in a competitive fixed rate for 2, 5, or 10 years
  • Access better rates with improved LTV
  • Release equity for home improvements or other purposes
  • Reduce monthly payments or shorten mortgage term
  • Switch from interest-only to repayment mortgage

Important Considerations

  • !Early repayment charges can be substantial (check first)
  • !Remortgaging costs may offset short-term savings
  • !Your circumstances may have changed (income, credit score)
  • !Property value may have decreased, reducing options
  • !Process takes 4-8 weeks - start early to avoid SVR
  • !Some deals have high fees that outweigh lower rates

Tips for Successful Remortgaging

Start Early

Begin shopping around 3-6 months before your deal ends. Some lenders allow you to lock in a rate up to 6 months in advance.

Check Your Credit Score

Review your credit report for errors and take steps to improve your score. A better score means better rates.

Use a Mortgage Broker

Brokers have access to exclusive deals, can navigate complex situations, and do the legwork for you (often for free).

Consider Total Cost, Not Just Rate

A mortgage with a slightly higher rate but no fees might be cheaper overall than a low-rate deal with £2,000 in fees.
