Thinking about switching your mortgage? Whether you're looking to save money, release equity, or find a deal that better suits your needs, remortgaging could be a smart move. Here's everything you need to know.

‍

What is Remortgaging?

‍

Remortgaging means moving your existing mortgage to a new deal – either with your current lender or a different one. You're not moving house; you're simply changing the mortgage on your current home.

‍

Why Remortgage?

‍

People remortgage for many reasons, including:

‍

  • Getting a better rate: Avoid high standard variable rates (SVRs) when your deal ends.
  • Releasing equity: Borrow more against your home’s increased value.
  • Consolidating debt: Roll debts into one (note: seek advice first).
  • Changing your mortgage type: Switch from interest-only to repayment or adjust your mortgage term.

‍

‍

When Should I Remortgage?

‍

It’s best to start shopping around 3–6 months before your current deal ends.

You may want to wait if:

‍

  • You're locked into a deal with high early repayment charges.
  • Your property's value has dropped.
  • Your credit score has recently been affected.

‍

‍

How Much Can I Borrow?

‍

This depends on:

‍

  • Your home’s value
  • Your equity
  • Your income and spending
  • Your credit history

A lower loan-to-value (LTV) generally means access to better interest rates.

How Does the Remortgaging Process Work?

‍

Here’s a step-by-step breakdown:

‍

  1. Review your current mortgage – including any early repayment charges.
  2. Check your credit score – and fix any issues.
  3. Compare deals – don’t just look at the interest rate; consider fees too.
  4. Speak to a mortgage adviser – they can help you find the best options.
  5. Apply for the new mortgage – your chosen lender will assess your application.
  6. Property valuation and legal checks – often covered by the lender.
  7. Complete the switch – your new lender repays your old mortgage and your new deal begins.

‍

‍

What Will It Cost?

‍

Be aware of potential costs such as:

‍

  • Early repayment charges
  • Exit fees
  • Arrangement or booking fees
  • Valuation and legal fees (some deals include these for free)

‍

‍

Want to Release Equity?

‍

If your property has increased in value, you may be able to borrow more – this is called equity release. It can be used for:

‍

  • Home improvements
  • A second property
  • Large purchases or events
  • Debt consolidation

Borrowing more increases your monthly payments or the loan term – make sure it’s affordable long-term.

What About Product Transfers?

‍

If you're happy with your current lender, ask about a product transfer. It’s often quicker than a full remortgage – but it’s still worth comparing deals elsewhere to make sure you’re getting the best rate.

‍

‍

Common Remortgaging Mistakes

‍

Avoid these common pitfalls:

‍

  • Leaving it too late – don’t default to your lender’s SVR.
  • Overlooking fees – a lower rate isn’t always cheaper.
  • Borrowing more than necessary – always budget carefully.
  • Ignoring your credit score – it matters more than you think.

Final Thoughts

‍

Remortgaging can offer great benefits – lower monthly payments, access to equity, or simply a more suitable deal. But it’s important to make an informed decision based on your personal circumstances.
