What is the difference between a revolving credit facility and a line of credit?

In the financial world, terms often overlap, causing confusion for borrowers trying to find the right funding solution. Two terms that frequently get mixed up are “revolving credit facility” and “line of credit”. At first glance, they seem to describe the exact same thing: a pool of money you can dip into, pay back, and draw from again. However, in professional and property investment circles, they can represent very different financial products.

For UK buy-to-let (BTL) landlords and property investors, understanding these distinctions is key to managing cash flow and expanding portfolios. Choosing the right structure may help you secure a new property, fund an urgent renovation, or manage temporary void periods without overpaying on interest.

Defining the terms: Line of credit vs revolving credit facility

To understand the difference, it helps to look at how these terms are generally used in the UK financial market.

A line of credit is a broad, generic term for any credit arrangement where a lender establishes a maximum credit limit that a borrower can tap into at any time. This can be unsecured or secured. Examples of a line of credit include personal overdrafts, business credit cards, or personal lines of credit. Once approved, you can choose when to spend the money and how much to draw down, up to the agreed limit.

A revolving credit facility (RCF) is generally a more formal, structured, and often larger financial agreement. In business and property finance, an RCF is typically used for corporate funding or property investment. It functions much like an institutional “overdraft” but is heavily tailored to specific business cycles or assets. Once you repay the borrowed principal (plus interest), that credit automatically becomes available to draw down again, without the need to submit a completely new application.

The secured buy-to-let revolving credit facility: A specialised property overdraft

When discussing these facilities in the context of UK property investment, we are not talking about unsecured business loans, credit cards, or generic business overdrafts. Instead, we are looking at a highly specialised product: the secured Buy-to-Let Revolving Credit Facility.

Offered to property investors through brokers like Promise Money, this facility is a secured product. It is secured as a second charge against residential buy-to-let property, sitting directly behind your existing first-charge mortgage. This means you do not have to disturb your current mortgage or trigger costly early repayment charges.

Unlike standard lines of credit, which might be unsecured and carry high variable rates, a secured property revolving credit facility provides several unique features:

• Interest on drawn funds only: You only pay interest on the money you actually use, not on the total facility limit. If you have a facility of £100,000 but only draw down £20,000 for a kitchen refurb, you only pay interest on that £20,000.
• Second-charge security: The facility is secured against your portfolio or a specific buy-to-let property, allowing you to unlock equity without refinancing your main mortgage.
• Rapid drawdowns: Once the facility is legally established, subsequent drawdowns are typically processed within 24 to 48 hours. This offers incredible speed when you need to act fast.
• Repeatable access: You can draw, repay, and draw again as many times as you like during the term of the agreement, without reapplying each time.

How it compares to bridging finance and remortgaging

Historically, UK landlords have relied on two main tools to release equity or fund fast property deals: bridging finance and remortgaging. A secured revolving credit facility competes directly with both of these options, often offering superior flexibility.

Bridging finance vs revolving credit

Bridging loans are short-term, secured loans typically used to “bridge” a gap in funding. Bridging finance is commonly categorised into open bridging loans (which have no firm exit date, though a clear plan is required) and closed bridging loans (which have a strict, pre-agreed repayment date, such as a pending property sale). Most bridging loans roll up interest, meaning you do not make monthly payments; instead, the accumulated interest is paid in full at the end of the term.

While bridging is excellent for single, large transactions, it can be expensive and inefficient if you have ongoing, smaller projects. Every time you need a new bridge, you must submit a fresh application, pay new valuation fees, and wait for legal underwriting. With a secured revolving credit facility, you only set up the product once. You can then use it repeatedly for multiple projects, avoiding the repetitive fees and delays associated with multiple bridging loans.

Remortgaging vs revolving credit

Remortgaging is another common path to releasing equity. However, if your existing first-charge mortgage has a competitive fixed rate, breaking it early could result in substantial early repayment charges (ERCs). Furthermore, the remortgaging process can take weeks or even months.

A secured revolving credit facility sits behind your first mortgage as a second charge, keeping your original low-rate mortgage completely intact. It acts as a ready standby facility, giving you access to cash within days rather than months, making it far more agile than traditional remortgages.

Real-world landlord scenarios

To see how a secured revolving credit facility works in practice compared to a traditional line of credit, let us look at some common property investment scenarios.

Scenario 1: Winning a property at auction

You find a run-down flat at auction that has excellent yield potential. Auctions typically require a 10% deposit on the day and completion within 28 days. Getting a standard mortgage in that timeframe is highly unlikely. By using your pre-arranged BTL revolving credit facility, you can draw the deposit or full purchase amount in 24 to 48 hours, secure the property, and then refinance onto a standard mortgage later at your convenience.

Scenario 2: Handling refurbishment and EPC upgrades

With changing energy efficiency regulations in the UK, landlords may need to upgrade their properties to meet higher Energy Performance Certificate (EPC) ratings. If you own multiple properties, upgrading them all at once can severely drain your cash reserves. An RCF allows you to draw down the exact funds needed for one property’s refurb, complete the work, let the property at a higher rent, and use the rental income or a light refinance to repay the facility before moving on to the next property.

Scenario 3: Managing void periods

Even the most successful landlords occasionally face void periods where a property sits empty between tenancies. During these times, mortgage repayments, council tax, and utility bills still need to be paid. A revolving credit facility can act as a safety net, letting you draw down small amounts to cover these essential costs and repaying the balance once a new tenant is in place.

Regulatory information and risk warnings

When exploring secured property finance, it is essential to work with a reputable broker. Promise Money is an FCA-authorised broker (Ref: 681423), not a direct lender. We help property investors compare options and find the most suitable, cost-effective secured facilities on the market. You can explore our options further by visiting our dedicated hub at promisemoney.co.uk/landlord-revolving-credit-100 or by speaking to an adviser directly on 01902 585020.

Secured borrowing of this nature carries serious responsibilities. Your property may be at risk if repayments are not made. If you fail to keep up with repayments on a secured facility, it could lead to legal action, repossession of your investment properties, increased interest rates, and additional late payment charges. Borrowers should always ensure they have a viable repayment strategy before drawing funds.

Lenders will review your credit history, but because the facility is secured against real property assets, there may be more flexibility than you would find with traditional, unsecured bank borrowing.
