What is the difference between revolving credit and non-revolving credit?
For UK buy-to-let (BTL) landlords, managing cash flow is vital for portfolio growth. Whether you need to fund a refurbishment, secure an auction deal, or cover a void period, having quick access to finance is crucial. When comparing funding options, you will encounter two primary structures: revolving credit and non-revolving credit.
Understanding what is the difference between revolving credit and non-revolving credit can help you make better financial choices and avoid unnecessary costs. This guide explores how these options compare, with a focus on property investment, and how products like a secured BTL revolving credit facility compare to alternatives like bridging finance or remortgaging.
What is revolving credit?
Not quite what you are looking for? Try these:
Revolving credit is a flexible arrangement allowing you to access funds up to an approved limit. Instead of taking a lump sum, you draw funds as needed, repay, and redraw without reapplying, acting like a rolling overdraft.
For property investors, a key example is a secured Buy-to-Let revolving credit facility, such as the one sourced by Promise Money. This is a secured facility sitting as a second charge behind your existing first-charge mortgage on a residential buy-to-let property. It is not an unsecured business loan, credit card, or generic commercial line of credit.
Once arranged, you can typically draw funds within 24 to 48 hours. Crucially, interest is only charged on drawn amounts, not the full facility limit, making it highly cost-effective for managing property costs.
What is non-revolving credit?
Non-revolving credit is a traditional form of borrowing where you receive a lump sum upfront and repay it over a set term. Once repaid, the account is closed. To borrow more, you must reapply and pay new setup fees.
Common examples for landlords include mortgages and bridging finance. Bridging loans bridge a funding gap, often for auction purchases. You can choose an open bridging loan (no fixed repayment date but a set window, typically 12 to 24 months) or a closed bridging loan (with a fixed exit date, such as a pending sale).
Most bridging loans roll up interest, meaning monthly payments are not typical; instead, interest is repaid at the end. Your property may be at risk if repayments are not made. Defaulting can lead to legal action, repossession, increased interest rates, and additional charges.
Key differences for UK property investors
To clarify what is the difference between revolving credit and non-revolving credit, consider these comparison points:
- Flexibility: Revolving credit lets you draw down what you need when you need it. Non-revolving credit yields a one-off lump sum on day one.
- Interest: On a secured revolving facility, you pay interest only on drawn funds. If your limit is £100,000 but you draw £20,000 for repairs, you pay interest on £20,000. Non-revolving loans charge interest on the full £100,000 immediately.
- Reusability: Revolving credit is reusable as you repay the balance. Non-revolving credit is single-use; once repaid, it is closed.
- Speed: Once set up as a second charge behind your first-charge mortgage, revolving drawdowns typically take 24-48 hours.
This is useful for landlords managing refurbishments, EPC upgrades, or auction deposits where staged or rapid funding is needed without paying interest on idle cash.

As a secured second charge, a BTL revolving credit facility carries risks. Your property may be at risk if repayments are not made. Defaulting may lead to legal action, repossession, increased interest rates, and additional charges. You can review responsible lending standards on the Financial Conduct Authority (FCA) website.

People also asked
Can I get an unsecured revolving credit facility for my property business?
No, the specialized revolving facilities designed for property development or landlord use, such as those sourced by Promise Money, are secured as a second charge against residential buy-to-let properties. They are not unsecured business loans, personal credit cards, or generic corporate revolving credit lines.
How does a secured revolving credit facility compare to remortgaging?
Remortgaging involves replacing your existing first-charge mortgage to release equity, which can take several months and may cause you to lose a highly competitive interest rate. A secured revolving credit facility sits behind your current mortgage as a second charge, allowing you to access cash quickly without altering your primary mortgage rate.
Are bridging loans open or closed?
Bridging loans can be either open, which have no firm exit date but must be repaid within an agreed window (typically 12 to 24 months), or closed, which have a fixed, predetermined date for repayment. Most bridging loans roll up interest, meaning you do not pay monthly, but rather clear the entire balance and interest at the end.
What are the consequences if I do not keep up repayments on a secured property facility?
Since the facility is secured against your property as a second charge, failing to keep up repayments can result in legal action, increased interest rates, additional administrative charges, and ultimately, the repossession of your property by the lender.
Is interest charged on the entire limit of a revolving credit facility?
No, interest is only charged on the funds you have actively drawn down. The remaining unused portion of your facility limit does not incur interest charges, making it highly cost-effective compared to traditional loans where interest is paid on the full principal from day one.
Summary of your funding choices
Choosing between revolving and non-revolving credit depends on your strategy. If you need a single lump sum to buy and hold a property long term, a traditional non-revolving mortgage is often ideal. However, if you need flexible, ongoing access to working capital for refurbishments, void periods, or fast auction bids, a secured BTL revolving credit facility may be far more cost-effective.
By sitting as a second charge behind your first mortgage, this facility acts as a property overdraft, protecting your current mortgage terms while ensuring rapid liquidity.
