Do I Pay Interest on the Full Facility Limit or Only on What I've Actually Drawn?

Do I Pay Interest on the Full Facility Limit or Only on What I’ve Actually Drawn?

When you secure a borrowing facility in the UK, whether it is for buying a property, renovating a home, or funding a business project, you will often hear the term “facility limit”. This is the maximum amount of money a lender has agreed to make available to you. However, a common question for many borrowers is: do i pay interest on the full facility limit or only on what i’ve actually drawn?

The short answer is that, in most cases, you only pay interest on the funds you have actually drawn down and are currently using. However, the exact terms depend heavily on the type of financial product you choose, how the facility is structured, and the specific terms set out by your lender. Understanding these details can help you save a significant amount of money on your borrowing costs.

Understanding Facility Limits and Drawdown Funds

To understand how interest is calculated, it helps to break down the two main components of this type of borrowing:

  • The Facility Limit: This is the total credit line approved by the lender. It represents the maximum amount you are allowed to borrow under the terms of the agreement.
  • The Drawn Amount (or Drawdown): This is the portion of the facility limit that you have actually transferred into your bank account or used to pay for goods, services, or property.

For example, if you secure a development facility of £200,000 but only withdraw £50,000 to cover the initial purchase of a property, your facility limit is £200,000, but your drawn amount is £50,000. Under normal circumstances, the interest charges will only accumulate on the £50,000 you are actively using, not the full £200,000.

How Bridging Loans and Property Development Facilities Work

In property finance, particularly with bridging loans and refurbishment facilities, drawdowns are very common. Property developers rarely need the entire loan amount on day one. Instead, they prefer to draw down funds in stages as the build or renovation progresses.

This staged approach is highly cost-effective because interest is typically only charged on the outstanding balance of the drawn funds. If you were to pay interest on the entire facility limit from the very beginning, the financing costs could quickly make the project unprofitable.

Open vs. Closed Bridging Loans

If you are considering a bridging loan, it is vital to understand the difference between open and closed structures:

  • Closed Bridging Loans: These loans have a fixed, agreed repayment date. This is typical when you have a clear exit strategy, such as a confirmed sale of another property on a specific date.
  • Open Bridging Loans: These do not have a rigid, fixed repayment date, though they will usually have a maximum term (often up to 12 or 24 months). They offer more flexibility but generally come with slightly higher interest rates because they carry more uncertainty for the lender.

The Reality of Rolled-Up Interest

Unlike standard residential mortgages where you make monthly repayments, most bridging loans feature rolled-up interest. This means you do not make monthly payments to the lender. Instead, the interest accrues monthly and is added to the outstanding loan balance, to be paid in full when the loan is redeemed.

While this assists with cash flow during a project, it means the total amount you owe will grow over time. Your property may be at risk if repayments are not made. If you default on the loan, you could face legal action, repossession of the property, increased interest rates, and substantial additional charges.

Fees You Might Pay on the Undrawn Balance

While you might not pay standard interest on the undrawn portion of your facility limit, you should be aware of other potential fees. Lenders make capital available to you, which means they cannot lend those funds to other clients. To cover this cost, some lenders charge specific fees on the undrawn portion of the facility:

  • Commitment Fees: This is a fee charged by some commercial lenders for keeping the facility open and reserving the funds for your future use. It is typically a small percentage (such as 1% per annum) calculated on the undrawn balance.
  • Facility Fees: This is an arrangement fee usually calculated as a percentage of the total facility limit. It is charged when the facility is first set up, regardless of how much you draw down.
  • Drawdown Fees: Some lenders charge an administration fee each time you request a new release of funds from your facility limit.

Always review your loan illustration and offer documents carefully to see if any commitment or non-utilisation fees apply to your specific agreement.

Managing Your Financial Health and Credit Score

Before entering into any large financial agreement or facility, lenders will conduct a thorough assessment of your financial situation. This includes examining your credit history to evaluate how you have managed debt in the past. To ensure you are in the best possible position before an application, it is wise to check your own credit report.

If you have any missed payments or defaults on your credit record, it may affect the interest rates you are offered, or the lender may require additional security. In serious cases, defaulting on a secured facility can lead to the repossession of the asset used as collateral, so keeping track of your credit file is an important first step.

Comparing Drawdown Facilities with Traditional Term Loans

A traditional term loan provides you with a lump sum of money on day one, and you pay interest on the entire amount from that moment forward. A drawdown facility offers far greater flexibility.

With a drawdown facility, you only pay for what you use, when you use it. For guidance on how different types of loans affect your overall costs, you can read the MoneyHelper bridging loans guide, which explains the mechanics of short-term property finance and the risks involved.

People also asked

What is a non-utilisation fee?

A non-utilisation fee is a charge levied by some lenders on the portion of a credit facility that has not been drawn down. It compensates the lender for committing capital that is not currently generating interest.

Do bridging loans require monthly payments?

No, most bridging loans do not require monthly payments. Instead, the interest is typically rolled up into the loan balance or retained from the initial advance, with the full amount repaid at the end of the term.

What happens if I cannot repay my facility limit at the end of the term?

If you cannot repay the facility, you may face default charges, increased interest rates, and legal action. Because bridging loans are secured, your property may be at risk of repossession if repayments are not made.

Can I pay off my drawn balance early?

Yes, many facility structures and bridging loans allow for early repayment, but some lenders may charge an early repayment fee or require a minimum term of interest, so it is important to check your contract terms.

Is the facility fee calculated on the drawn amount or the total limit?

The facility fee, also known as the arrangement fee, is typically calculated as a percentage of the total facility limit rather than just the amount you choose to draw down initially.

Summary

In conclusion, while you will generally only pay interest on the money you have actually drawn down, you must remain aware of setup fees, potential commitment fees on the undrawn balance, and the compounding nature of rolled-up interest. Always compare offers carefully and ensure you have a robust exit plan before taking out any secured financial facility.
