 Interest Only Mortgages

A second charge mortgage, as the name suggests, is a new mortgage borrowed against your existing property without the need to remortgage.

It's secured on your property, ranking behind your primary or first charge mortgage in terms of priority.

It offers a flexible and potentially cost-effective way to raise additional funds while still maintaining your current mortgage arrangements.

There are numerous advantages to second charge mortgages. Whether you're looking to:

  • pay for home improvements
  • consolidate debts
  • fund lifestyle expenses
  • or even buy an investment property…

second charge mortgages are an accessible option and can sometimes be better than remortgaging, further advances or other types of loans depending on your specific situation.

Loan amounts can start from as low as £10,000 and offer competitive rates.

And there’s the potential to borrow up to six times your income or higher (more than remortgaging or further advances).

Second Charge Mortgage Calculator

We've developed a handy Second Charge Mortgage Calculator tool to give you a rough understanding of the costs associated with a second charge mortgage.

It offers an estimate of potential interest payments based on the amount you're looking to borrow, the length of term and your interest rate.

How our Second Charge Mortgage Calculator Works


First, input the amount you want to borrow.

You can borrow up to 6 times your income (or potentially more in some cases) and typically up to 100% of your property value (combined with your first charge mortgage balance). But the higher your LTV (loan-to-value ratio) and income multiple, the higher your interest rate will be.


Next, enter the length of term you want to borrow for.

The longer you borrow for, the lower your repayments will be. But, your loan will last longer, so you’ll be racking up interest for longer and will likely pay more interest overall.


Finally, input your interest rate.

We’ve set the default to 5.99%, but depending on your situation your rate could be higher (you can get a free quote from us to confirm this).

After submitting this information, the calculator displays an estimate of the breakdown for your mortgage repayments: how much you’ll pay each month in capital repayments vs interest.

What are Second Charge Mortgages used for?

Second Charge Mortgages are versatile financial tools that can provide the flexibility you need to achieve various goals.

As they are essentially secured loans taken out against the equity available in your property, they offer an additional funding avenue without altering your existing mortgage agreement.

This unique setup allows borrowers to access substantial amounts of money without disturbing their first mortgage.

The funds from a second charge mortgage are typically available within two to three weeks, and loans can start from just £10,000, making them accessible and efficient.

Perhaps the most compelling aspect of second charge mortgages is the range of things they can be used for:

  • Home improvements.
  • Debt consolidation (possibly lowering your overall interest costs).
  • Lifestyle funding (weddings, school fees, car purchases, and more).
  • Business needs.
  • Investment in property

Costs and Terms of Second Charge Mortgages

Understanding the costs and terms of second charge mortgages is vital to making informed financial decisions.

We believe in empowering our clients with the knowledge they need to navigate their financial journey confidently.

Several factors can affect the potential loan amount you can secure through a second charge mortgage:


First, your income plays a significant role.

Generally, you could potentially borrow up to six times your income, providing considerable borrowing power.


The loan-to-value (LTV) ratio, which represents the relationship between the loan amount (plus your first charge mortgage balance) and the property's value, is another crucial factor.

At Clifton Private Finance, we can source up to 100% LTV – but you just need to keep in mind that the higher your LTV, the higher your interest rate tends to be.


Finally, the type of property - residential or buy-to-let – can also influence your loan conditions, as well as your credit score.

Here are a few other aspects of second charge mortgages to be aware of:

  • You typically have the option to roll up fees and add them to the loan amount, which can simplify repayments and release immediate financial pressure, freeing up your cashflow for home improvements, for example.
  • You can also get second charge mortgages that come with no early repayment fees (ERCs) even with fixed rates, providing flexibility and peace of mind.
  • The loan term can range from 1 to 30 years, allowing for adjustments based on your financial situation and repayment capability.
