Remortgaging is something many homeowners in London will need to consider at some point this year, yet it’s often put off simply because it feels complicated. 

In reality, with the right remortgaging advice, the process can be straightforward and a very worthwhile step.

Whether you’re coming to the end of your current mortgage deal or just reviewing your options, this guide will walk you through the process in a clear, practical way, just as one of our mortgage advisers would.

James Ashaye, Mortgage Broker in Edmonton, North London said:

“Remortgaging isn’t just about finding a lower rate; it’s about making sure your mortgage continues to suit your life as it changes. Our role is to guide you through the options clearly and help you make a confident, well-informed decision that works both now and in the future.”

Why Consider Remortgaging in London?

For many homeowners, remortgaging isn’t just about getting a better rate, it’s about making your mortgage work for your current lifestyle.

People typically look at remortgaging when:

• Their current deal is ending, and costs are set to rise: Moving onto a lender’s standard variable rate can increase monthly payments significantly if no new deal is arranged. 
• They want to reduce monthly outgoings: A more competitive rate or adjusted term can help ease financial pressure, particularly if circumstances have changed. 
• They’re looking to release equity: Some clients use remortgaging to fund home improvements, support family, or achieve longer-term financial goals. 
• Their circumstances have changed: Income, employment, or family situations evolve over time, and your mortgage should reflect that. 

At Thomas Oliver, we always start with a simple question: what are you trying to achieve? From there, we build the right solution around you.

When Should You Start the Remortgaging Process?

One of the most common mistakes we see is leaving things too late.

In most cases, you can secure a new mortgage deal around 3 to 6 months before your current one ends, helping you avoid unnecessary costs. 

Starting early gives you time to explore your options properly rather than rushing into a decision.

Your Thomas Oliver mortgage adviser will keep track of your mortgage timeline and prompt you when it’s the right time to review, so you’re always one step ahead.

Step 1: Review Your Current Mortgage

Before making any decisions, it’s important to understand exactly where you stand.

• Check your current interest rate and monthly payments: This gives you a clear benchmark so you can see whether a new deal genuinely offers better value. 
• Confirm when your deal ends: Timing your remortgage correctly helps you avoid higher rates and unnecessary costs. 
• Look for early repayment charges (ERCs): These can apply if you switch too soon, so it’s important to factor them into your plans. 
• Request your outstanding balance: Knowing exactly how much you owe ensures any new mortgage is structured accurately. 

We review all of this with you and explain it in plain English, no jargon, just clarity.

Step 2: Speak to a Mortgage Adviser

Remortgaging isn’t just about picking a rate online or with a high street lender; it’s about making the right decision for your situation.

• Get professional mortgage advice before making decisions: An adviser can help you understand the full picture, including costs, flexibility and long-term impact. 

The Thomas Oliver mortgage advice team search across lenders, explain your options clearly, and recommend what genuinely suits your needs, not just what looks cheapest at first glance.

Step 3: Choose the Right Remortgage Deal

This is where the detail really matters.

• Fixed or variable rate: Fixed rates offer stability, while variable rates can change depending on market conditions. 
• Length of the deal (e.g. 2 or 5 years): Your choice should reflect how long you want certainty and how your plans may evolve. 
• Fees versus rate: A lower rate with higher fees isn’t always better overall, so it’s important to look at the total cost. 
• Loan-to-value (LTV):  The amount you borrow compared to your property value affects the deals available to you. 

Your mortgage adviser will present clear, side-by-side comparisons so you can make a confident, informed decision.

Step 4: Submit Your Remortgage Application

Once you’ve chosen a deal, the application process begins.

• Provide documents such as payslips, bank statements and ID: Lenders use this information to assess affordability and verify your circumstances. 
• Complete the application accurately: Getting the details right helps avoid delays and keeps things moving smoothly. 
• The lender will then assess affordability: They review your credit profile, and confirm the mortgage is suitable. 

We handle the paperwork, submit everything correctly, and manage the process on your behalf.

Step 5: Property Valuation and Mortgage Offer

At this stage, the lender confirms the property value and finalises your offer.

• The lender arranges a valuation: This ensures the property supports the amount you wish to borrow. 
• Your property value affects your deal: A higher value can improve your loan-to-value and open up better rates. 
• You receive a formal mortgage offer if approved: This outlines the terms of your new mortgage. 

Our mortgage advisers liaise with all parties and keep everything progressing smoothly.

Step 6: Legal Work (Conveyancing)

Even though you’re not moving home, legal work is still required.

• A solicitor transfers the mortgage to your new lender: This ensures the new lender is correctly registered against your property. 
• Checks and Land Registry updates are completed: These confirm ownership and formalise the change. 

At Thomas Oliver we coordinate the process behind the scenes to avoid delays and keep things straightforward.

Step 7: Completion of Your Remortgage

This is where everything comes together.

• Your new lender pays off your existing mortgage: Your previous loan is cleared in full. 
• Your new mortgage begins: The new rate and terms take effect immediately. 
• You start your new monthly payments: Your payments now reflect your updated deal. 

Your mortgage adviser will stay with you right through to completion, making sure everything is finalised correctly.

Understanding Your Options and the Bigger Picture

Remortgaging isn’t always a one-size-fits-all solution.

Depending on your circumstances, there may be different routes to consider, including standard remortgages, interest-only options, or solutions designed for later life lending. 

Some clients may also look at:

• Extending their mortgage term to reduce payments 
• Consolidating debts into one manageable repayment 
• Planning ahead for retirement or long-term financial goals 

This is where tailored advice becomes essential.
