Do I pay stamp duty land tax when setting up a revolving credit facility?
For UK property investors and buy-to-let (BTL) landlords, understanding tax obligations is a vital part of managing a profitable portfolio. When looking to raise capital for renovations, auction purchases, or portfolio expansion, many landlords consider flexible finance solutions. A highly versatile option is a secured revolving credit facility.
When arranging this type of funding, a common question arises: do i pay stamp duty land tax when setting up a revolving credit facility? Fortunately, the short answer is no. Because setting up a credit facility is a financing arrangement rather than a property purchase or transfer of land ownership, Stamp Duty Land Tax (SDLT) is not triggered during the setup phase.
In this comprehensive guide, we will explore why SDLT does not apply to setting up a secured revolving credit facility, how this product operates, and the scenarios where property taxes might still apply to the funds you draw down.
Why SDLT Does Not Apply to Setting Up a Revolving Credit Facility

To understand why you do not pay tax on this setup, it is helpful to look at what Stamp Duty Land Tax actually is. According to the official Gov.uk guide on Stamp Duty Land Tax, SDLT is a tax charged on the purchase or transfer of land and property in England and Northern Ireland. Similar taxes apply in Scotland (Land and Buildings Transaction Tax) and Wales (Land Transaction Tax).
A buy-to-let revolving credit facility, such as the one offered by Promise Money, is a secured loan product. It is secured as a second charge against your existing residential buy-to-let property, sitting safely behind your first-charge mortgage. Because setting up this facility does not involve transferring ownership of the property, acquiring new land, or changing the deeds, no SDLT is due. It is purely a borrowing mechanism, similar to a secured property overdraft.
How a Secured BTL Revolving Credit Facility Works
Unlike an unsecured business loan, a credit card, or a generic business line of credit, a BTL revolving credit facility is a fully secured financial product. It is designed specifically for professional landlords and property investors. Here is how it typically functions:
- The Secured Second Charge: The facility is secured against your investment property as a second charge. This means your first-charge mortgage remains completely untouched, allowing you to avoid costly early repayment charges.
- Draw, Repay, and Repeat: Once the facility is arranged, you are granted a credit limit. You can draw down funds as needed, repay them when cash flow allows, and draw them down again without having to submit a new application.
- Interest on Drawn Funds Only: You only pay interest on the money you have actually drawn down, not on the total facility limit. This makes it a highly cost-effective safety net for emergency expenses or sudden opportunities.
- Rapid Access: Once the initial setup is complete, future drawdowns can typically be processed within 24 to 48 hours.

When Might Stamp Duty Apply to Your Drawn Funds?
While the act of setting up the revolving credit facility is tax-free, the way you use the funds can trigger SDLT. If you draw down capital from your facility to purchase a new buy-to-let property, that new purchase will be subject to standard SDLT rules.
For UK landlords, purchasing an additional residential property typically triggers the higher rates of SDLT. This includes a 3% surcharge on top of the standard residential rates in England and Northern Ireland. Therefore, if you draw £50,000 from your facility to use as a deposit for an auction purchase, you must budget for the SDLT due on the purchase price of that new asset.
Comparing Secured Revolving Credit to Other Landlord Finance Options
When looking to release equity from an existing property, landlords traditionally choose between remortgaging and bridging finance. Here is how a secured revolving credit facility compares to these options:
Revolving Credit vs. Remortgaging
Remortgaging involves replacing your existing first-charge mortgage with a larger one to release cash. While there is no SDLT on a standard remortgage, this process can take months and may force you to give up a highly competitive historic interest rate. You might also face steep early repayment charges. A secured revolving credit facility sits behind your current mortgage, leaving your primary rate intact.
Revolving Credit vs. Bridging Finance
Bridging finance is a popular short-term tool, but it lacks ongoing flexibility. Most bridging loans are structured so that interest rolls up monthly, meaning you do not make monthly payments, but the outstanding balance grows until the loan is redeemed. Bridging loans can be “closed” (with a fixed exit date and clear repayment plan, such as a pending property sale) or “open” (with no firm exit date, though typically capped at 12 to 24 months).
In contrast, a revolving credit facility allows you to pay down the balance and reuse the limit continuously, offering a long-term capital tool rather than a one-off “bridge.”
Real Landlord Scenarios: Using a Revolving Credit Facility
To see how this works in practice, consider these common landlord scenarios where a secured revolving credit facility provides a distinct advantage:
- The Quick Auction Purchase: A landlord spots a discounted flat at auction. They draw down £40,000 within 24 hours to secure the deposit and complete the refurbishments, later refinancing onto a standard mortgage to repay the facility.
- EPC Upgrades: To meet changing energy efficiency standards, a landlord draws £15,000 to install a new boiler, insulation, and double glazing, paying off the balance as rental income accumulates.
- Managing Void Periods: During an unexpected tenant transition, the landlord draws funds to cover the first-charge mortgage payments and minor cosmetic repairs, preventing any risk of payment shortfalls.
Risk Warnings and Credit Health
As with any secured financial product, it is vital to understand the risks involved. Your property may be at risk if repayments are not made. Failing to meet your obligations can result in serious financial and legal consequences, including legal action, repossession of your investment property, increased interest rates, and additional administrative charges.
Before applying for any secured facility, lenders will conduct thorough credit searches to assess your financial history.

Do I pay stamp duty when refinancing a buy-to-let mortgage?
No, standard refinancing or remortgaging does not attract Stamp Duty Land Tax, provided there is no transfer of equity or change in property ownership.
Is interest on a secured revolving credit facility tax-deductible?
For individual landlords, mortgage and loan interest is generally subject to section 24 tax rules, meaning you receive a 20% tax credit instead of a direct deduction, though corporate landlords operating through a limited company may still deduct finance costs in full.
What is the difference between a first charge and a second charge?
A first charge is your primary mortgage, which has the first claim on your property if it is sold or repossessed, while a second charge is a subordinate secured loan that sits behind it.
Can I use revolving credit to fund a property deposit?
Yes, many landlords use a secured revolving credit facility to quickly access deposit funds for new property purchases or auction acquisitions.
How does a revolving credit facility differ from a business credit card?
A revolving credit facility is secured against high-value property assets, allowing for much larger borrowing limits and typically lower interest rates than an unsecured business credit card.
