Mezzanine Finance in Southwark
Additional leverage beyond senior debt to maximise returns on your Southwark development project.
Mezzanine finance occupies the middle layer of the development capital stack, sitting between senior debt and the developer's own equity. By adding mezzanine to your funding structure, you can increase total borrowing from the typical 65-70% loan-to-cost offered by senior lenders up to 85-90% of total project costs — significantly reducing the cash you need to invest from your own resources. For Southwark developers looking to maximise returns on equity, stretch their capital across multiple projects, or take on larger schemes than their personal funds would otherwise allow, mezzanine finance is a powerful and increasingly popular funding tool.
What Is Mezzanine Finance?
Mezzanine finance is a subordinated layer of debt that bridges the gap between your senior development loan and your own equity. In a standard development finance structure, the senior lender provides 60-70% of total project costs as a first-charge loan, and the developer funds the remaining 30-40% from their own cash reserves. Mezzanine finance reduces that equity requirement by providing an additional 15-25% of funding, secured by a second charge behind the senior lender.
The term "mezzanine" comes from the Italian word for "middle" — and that is precisely where this funding sits: in the middle of the capital stack, between the senior debt below and equity above. Because mezzanine lenders accept a subordinated position (meaning they are repaid after the senior lender in the event of a default), they charge higher interest rates — typically 1% to 2% per month — to compensate for the increased risk. However, for developers, this cost is often justified by the significantly higher returns achievable on the reduced equity base.
The Capital Stack with Mezzanine Finance
Understanding where mezzanine fits in the capital stack is key to appreciating its value. Consider a typical Southwark development project with £2 million in total costs.
Example: £2,000,000 total project cost — 8-unit new build near Canada Water
Without mezzanine, the developer would need £700,000 in equity. With mezzanine, the equity requirement drops to £200,000 — freeing up £500,000 for other projects or contingency reserves.
When to Use Mezzanine Finance
Mezzanine finance is not appropriate for every development project. It adds cost and complexity to the funding structure, and the project must generate sufficient profit to absorb the higher blended finance cost while still delivering an acceptable return. It is most valuable in the following scenarios.
- Preserving capital across multiple projects: If you have £700,000 available and want to develop a single £2 million scheme, you could fund the equity yourself. But by using mezzanine, you could potentially fund the equity on three £2 million schemes simultaneously, dramatically increasing your total development activity and profit across Southwark.
- Taking on larger schemes: Mezzanine allows you to pursue projects that would otherwise be beyond your capital base. A £5 million development near Elephant & Castle requiring £1.5 million in equity becomes feasible with £500,000 of your own money plus mezzanine finance for the balance.
- Maximising return on equity: Because you are investing less of your own money, the return on your equity is amplified when the project succeeds. On a well-performing Southwark scheme, the return on a £200,000 equity contribution can be dramatically higher than on a £700,000 contribution, even after accounting for the mezzanine interest cost.
- Competitive site acquisition: Having mezzanine in place gives you certainty of funding, allowing you to move quickly and confidently when a desirable Southwark development site comes to market.
- Risk sharing: By reducing your personal capital at stake, mezzanine effectively shares the financial risk with an additional lender, which some developers find valuable on larger or more complex projects.
Intercreditor Agreements
When two lenders are involved in the same project — a senior lender holding the first charge and a mezzanine lender holding the second charge — their relationship must be governed by an intercreditor agreement (ICA). This is a legally binding document that establishes the rules of engagement between the two parties, and it is one of the most important documents in any mezzanine-backed development.
The intercreditor agreement typically covers the following areas.
- Priority of payments: Confirming that the senior lender is repaid in full before the mezzanine lender receives any repayment. This "waterfall" structure is fundamental to the arrangement.
- Enforcement rights: Defining when and how the mezzanine lender can enforce their security if the developer defaults. Typically, the mezzanine lender must observe a "standstill period" (often 60-90 days) before taking enforcement action, giving the senior lender time to protect their position.
- Consent and notification: Specifying which actions require the consent of both lenders — for example, changes to the build programme, additional borrowing, or material amendments to the project.
- Cure rights: Allowing the mezzanine lender to "cure" a default under the senior facility (for example, by paying overdue interest) to prevent the senior lender from enforcing and potentially wiping out the mezzanine position.
- Information sharing: Requiring the senior lender to share monitoring reports, drawdown information, and default notices with the mezzanine lender.
We coordinate the intercreditor negotiation between senior and mezzanine lenders, working with experienced lawyers who specialise in these arrangements. Our aim is always to ensure the ICA is agreed efficiently without delaying your project's funding timeline.
Blended Rate Examples
One of the key considerations when using mezzanine finance is the blended interest rate across your total debt stack. While mezzanine rates are higher than senior rates, the mezzanine tranche is typically a smaller proportion of total borrowing, so the overall blended rate remains manageable.
Scenario: £2M total costs, Bermondsey warehouse conversion
- Senior debt: £1,300,000 at 0.85% pm = £11,050/month interest
- Mezzanine: £500,000 at 1.35% pm = £6,750/month interest
- Total monthly interest: £17,800
- Blended rate across £1,800,000 total debt: 0.99% pm
Over a 14-month project, total interest cost would be approximately £249,200. If the project generates £600,000 profit, the developer keeps £350,800 on a £200,000 equity investment — a return on equity of 175%.
Comparison: Same project without mezzanine
- Senior debt only: £1,300,000 at 0.85% pm = £11,050/month interest
- Developer equity required: £700,000
- Total interest over 14 months: £154,700
- Developer profit: £600,000 minus £154,700 = £445,300
- Return on equity (£700,000): 64%
The developer earns more absolute profit without mezzanine (£445,300 vs £350,800) but achieves a far higher return on their invested equity with mezzanine (175% vs 64%). The freed-up £500,000 could fund equity on additional projects.
Mezzanine vs Stretched Senior
An alternative to mezzanine is stretched senior finance — a single facility that provides higher leverage (75-80% LTC) without the need for a second lender. Understanding when each approach is preferable helps you choose the right structure.
| Feature | Senior + Mezzanine | Stretched Senior |
|---|---|---|
| Maximum LTC | 85-90% | 75-80% |
| Number of lenders | Two (senior + mezzanine) | One |
| Legal complexity | Intercreditor agreement required | Single facility agreement |
| Blended rate | Typically 0.90-1.10% pm | Typically 0.85-1.10% pm |
| Legal costs | Higher (two sets of legals + ICA) | Lower (single facility) |
| Best for | Maximum leverage (85%+ LTC) | Moderate leverage, simpler structure |
For Southwark projects where you need 85% LTC or above, a senior plus mezzanine structure is the only option. For projects where 75-80% LTC is sufficient, stretched senior may be simpler and marginally cheaper. We assess both options for every project and recommend the structure that delivers the best overall outcome.
Eligibility for Mezzanine Finance
Mezzanine lenders are selective because their subordinated position carries higher risk. The following criteria are typical across our panel of mezzanine providers.
- Senior facility in place: A senior development finance facility must be arranged or in the process of being arranged with a lender who accepts mezzanine behind them.
- Adequate profit margin: The project must demonstrate sufficient profit to absorb the combined cost of senior and mezzanine debt. Most mezzanine lenders want to see a minimum 20% profit on cost.
- Developer experience: Most mezzanine providers prefer developers with at least 2-3 completed projects of similar scale. Some will consider less experienced developers on strong projects in prime Southwark locations.
- Full planning permission: Mezzanine lenders almost universally require full planning consent to be in place before committing funds.
- Minimum equity contribution: You must retain at least 10% of total costs as your own equity — mezzanine lenders will not fund 100% of the equity gap.
- Credible exit strategy: A clear plan for repaying both the senior and mezzanine facilities on project completion.
