The second charge mortgage process is a fast, and straightforward process with the right support.

It’s much simpler and quicker than the first charge mortgage process and can often be completed in just a matter of days.

In this guide, we break down the full process, look into a few key stages and dive into how long you can expect the process to take depending on your circumstances.

The Second Charge Mortgage Process

The second charge mortgage process works as follows:

  1. Contact a broker – The first step is to contact a broker (or look to source a lender yourself). A good broker will first look to understand your circumstances and provide an initial guide on whether you’re likely to qualify and a rough monthly cost based on your circumstances.
  2. Get a formal quote – Once you’re confident that you will qualify and are happy with the costs, deeper research can take place and you will be given a more formal quote. This quote, known as a KFI, breaks down all the costs in detail and gives you clarity on the terms at which you’ll be borrowing.
  3. Accept the quote and apply – If you’re happy, you can accept the quote and formally apply for the loan. This will require some form filling (the broker will usually do this for you) and a few documents may be required (ID, proof of address, proof of income and bank statements). They’re not required in every case, but it’s best to have them ready to avoid slowing things down.
  4. Underwriting and formal offer – The lender will then underwrite the application in full. If all goes well here, a formal offer can be issued to you, confirming that they’re happy to lend. At the same time as the loan is being underwritten, the broker will arrange for your existing mortgage lender to consent to you placing a second charge on the property.
  5. Accept offer and complete – If you’re happy with the offer (in most cases it will be as agreed on the KFI), then you simply sign the paperwork and your loan can complete.

Stage 1: The Enquiry and KFI

Many borrowers are unsure what to expect during this stage, so we’ll break it down a little further.

During your first call, your broker will look to gather details on your current circumstances, including your income, property, credit history and the purpose of the loan.

This information then enables them to understand your circumstances and begin the process of matching you with the perfect lender.

Matching you to a lender will be based on credit, affordability criteria, LTV, income type, lender rates and fees and matching how quickly they can complete the application against how quickly you need the funds.

Ensuring the right lender is chosen initially is a really key step and can prevent a lot of problems later on.

Once you’re matched with the right lender, you’ll receive a KFI – a formal quote. The KFI is a standard document that follows a strict format, allowing you to easily compare competing offers in a simple way.

The KFI will include key details such as:

  • Loan amount 
  • Interest rate (fixed/variable) 
  • Monthly payments 
  • Fees and total cost
  • Early repayment charges
  • Broker fees

These are all key factors that should be carefully considered before you apply.

Valuations and Legal Requirements

The property valuation is used to confirm the value of your property and the amount of equity available to borrow against.

In many cases, a desktop valuation is possible, also known as an AVM. This is a computer generated valuation that can be completed without the need for an inspection of the property.

Whether an AVM is possible for your loan will depend on the loan size, LTV, lender and the amount of property data available in your area.

The legal work involved in second charge borrowing is very light touch compared to first charge mortgages.

In many cases, you do not need to appoint a solicitor and the legal work happens behind the scenes with very little input from the borrower.

How Long Does Funding Take?

While applications can be completed in just a few days, and we occasionally fund applications in less, most applications take around 2-3 weeks.

There are several factors that can impact the speed of completion, with the main ones being:

  • Complexity around the income or credit history of the borrower
  • A valuation being required that takes longer than expected
  • A backlog at the lender (this can be avoided by choosing the right lender
  • The borrower being slow to respond to requests

When more than one issue arises, things can take much longer, causing frustration for everyone involved.

For this reason, it’s important to follow these key steps to speed up your application:

  • Provide documents early and accurately
  • Respond quickly to lender queries
  • Work with lenders known for fast completions
