What is Mezzanine Finance?
A subordinated layer of debt that sits between the senior loan and developer equity in the capital stack, reducing the cash you need to invest.
Mezzanine finance is a form of subordinated debt used in property development to bridge the gap between the senior loan facility and the developer's own equity. In a typical Westminster development, the senior lender — usually a bank, fund, or specialist development finance provider — will advance 60-70% of total project costs as a first-charge loan. Without mezzanine finance, the developer must fund the remaining 30-40% from their own cash reserves or investor equity. Mezzanine finance fills a substantial portion of that gap, typically covering an additional 15-25% of costs, so the developer's equity contribution drops to as little as 10-15%.
The term "mezzanine" comes from the architectural concept of a mezzanine floor — an intermediate level between the ground floor and the first floor. In finance, it describes debt that occupies the middle layer of the capital stack, sitting above the developer's equity (which bears the most risk) but below the senior debt (which has the strongest security position). Because the mezzanine lender takes a second-charge position behind the senior lender, they bear more risk than the senior lender and therefore charge a higher rate of interest to compensate for this subordinated position.
For Westminster developers, mezzanine finance is a powerful tool for maximising returns on capital. By reducing the equity required for each project, developers can pursue larger schemes than their cash reserves would otherwise allow, or deploy their capital across multiple projects simultaneously to diversify risk and amplify returns. In a borough where land values frequently exceed £5,000 per square foot in prime locations and total development costs regularly run into the tens of millions, the ability to reduce equity from 35% to 10% of costs represents a significant strategic advantage.
The mezzanine facility is governed by its own loan agreement and secured by a second legal charge on the development property, a debenture over the borrowing entity, and personal or corporate guarantees from the developer. The relationship between the senior lender and the mezzanine lender is regulated by an intercreditor agreement, which establishes the rights, obligations, and enforcement priorities of each party. Our team manages the entire structuring process, from identifying the right combination of senior and mezzanine lenders to negotiating the intercreditor terms that protect your interests.

Why Westminster Developers Use Mezzanine
With average development costs in Westminster exceeding £500 per square foot for construction alone, and land values in prime areas reaching £10,000+ per square foot, the total capital required for even a modest scheme can be substantial. Mezzanine finance enables developers to participate in these high-value projects without tying up excessive equity in a single scheme, preserving capital for future opportunities and improving overall portfolio returns through the judicious use of leverage.

How the Capital Stack Works
The capital stack represents the total funding structure of a development project, arranged by priority of repayment. The senior lender sits at the bottom with a first legal charge on the property, meaning they are repaid first from any sale or refinance proceeds. This priority position means they bear the least risk and therefore charge the lowest rate.
The mezzanine lender occupies the middle layer with a second charge. They are repaid only after the senior lender has been made whole, which exposes them to more risk. To compensate, mezzanine rates are typically 40-100% higher than senior rates. However, even with this premium, the blended cost of the combined facility is significantly lower than the return on equity that the developer expects to earn from the project.
The developer's equity sits at the top of the stack. It is the last to be repaid and the first to absorb any losses if the project underperforms. This is why equity commands the highest return — and why reducing the amount of equity required through mezzanine finance can dramatically improve the developer's return on capital invested.

When to Use Mezzanine Finance
Mezzanine finance is the right tool when you need to reduce equity, scale your portfolio, or bridge a funding gap in your capital structure.
Reduce Equity Requirement
The most common use of mezzanine finance is to reduce the developer's equity contribution from 30-40% to 10-15% of total project costs. For a Westminster development with total costs of £8 million, this could mean reducing your cash outlay from £2.8 million to just £800,000 — freeing up £2 million of capital for other purposes. The cost of the mezzanine facility is more than offset by the improved return on the reduced equity deployed, provided the development achieves a healthy profit margin.
Maximise Leverage Across Projects
Experienced Westminster developers use mezzanine finance strategically to spread their equity across multiple simultaneous projects. Rather than committing £3 million of equity to a single scheme, a developer might deploy £1 million across three mezzanine-funded projects, tripling their exposure to the market while diversifying risk. This portfolio approach is particularly effective in Westminster, where the strong residential market supports consistent demand for newly developed or refurbished properties across multiple price points and locations.
Bridge a Funding Gap
Mezzanine finance can solve situations where the senior lender's facility does not stretch as far as anticipated. This often occurs when a development encounters unexpected costs, when the senior lender's valuation is lower than expected, or when planning conditions require additional expenditure. In Westminster, where Section 106 obligations and Community Infrastructure Levy charges can add significant cost, mezzanine finance provides a structured solution to fill these gaps without the developer needing to inject additional personal capital at short notice.
Mezzanine Finance vs Stretched Senior
Two routes to higher leverage — understanding which is right for your Westminster development project.
Senior + Mezzanine
Two separate lenders
Senior and mezzanine facilities provided by different institutions, each with their own terms and agreements
Up to 90% combined LTC
Higher total leverage typically available through a two-lender structure, reducing equity to 10%
Intercreditor agreement required
Legal framework governing the relationship between lenders adds complexity but provides clear rights for all parties
Higher blended rate
The premium on the mezzanine tranche increases the overall blended cost of debt compared to a single-lender solution
Suited to larger schemes
The legal costs and complexity of a two-lender structure are best absorbed by projects of £2 million+ total costs
Stretched Senior
Single lender
One lender provides the entire facility at a higher LTC than standard senior terms, simplifying the legal structure
Up to 80-85% LTC
Lower maximum leverage than a senior-plus-mezzanine structure, but still a significant improvement on standard 65% LTC
No intercreditor agreement
Single-lender structure eliminates the need for an ICA, reducing legal costs by £10,000-£25,000 and speeding up the process
Blended rate in a single facility
The lender prices the additional risk into a single blended rate, typically 0.80-1.10% pm across the whole facility
Suited to smaller and mid-sized projects
The simplicity and speed of a single-lender structure makes it efficient for projects under £5 million total costs

The legal framework that makes senior-plus-mezzanine structures work, protecting the interests of all parties involved.
Payment Waterfall
The ICA establishes a strict payment waterfall that determines the order in which proceeds from the development are distributed. The senior lender receives all principal and interest owed to them first. Only after the senior facility is fully repaid does the mezzanine lender receive their return. The developer's profit is paid last, after both debt tranches are cleared. This waterfall protects the senior lender's position and is why senior rates remain competitive even when mezzanine debt is layered behind them.
Standstill & Cure Rights
If the developer defaults on the senior loan, the ICA typically provides a standstill period of 90-180 days during which the mezzanine lender cannot enforce their second charge. During this period, the mezzanine lender has cure rights, meaning they can remedy the default by paying off the developer's arrears to the senior lender. This protects the mezzanine lender's investment by preventing the senior lender from immediately selling the property at a distressed value that might not cover the combined debt.
Step-In Rights
The ICA may grant the mezzanine lender step-in rights, allowing them to take over the management or ownership of the development if the developer fails to perform their obligations. This could involve appointing a new contractor, taking over project management, or even acquiring the developer's equity stake. Step-in rights give the mezzanine lender a mechanism to protect their investment by ensuring the project is completed and generates sufficient value to repay both the senior and mezzanine facilities. Our team negotiates these provisions to ensure a balanced outcome for all parties.
Our Role in Intercreditor Negotiation
Negotiating the intercreditor agreement is one of the most complex aspects of arranging mezzanine finance. The senior lender, mezzanine lender, and developer all have competing interests that must be balanced within a single legal framework. Our team has structured dozens of intercreditor agreements for Westminster developments and works alongside specialist property solicitors to ensure the terms are fair, practical, and do not create unnecessary restrictions on the developer's ability to manage the project. We also leverage existing relationships between lenders who have pre-agreed intercreditor templates, which can significantly reduce legal costs and accelerate the completion timeline.

Mezzanine Finance in the Westminster Market
Why Westminster's development landscape makes mezzanine finance a particularly effective tool for developers.
Westminster presents a unique environment for mezzanine-funded development. The borough's combination of exceptional end values, scarce development opportunities, and high barriers to entry creates conditions where leverage enhancement through mezzanine finance can generate outsized returns for developers who understand how to structure their capital effectively.
In areas such as Mayfair, Belgravia, and St James's, completed residential values regularly exceed £2,000 per square foot, with prime penthouse units achieving £4,000-£5,000 per square foot. These exceptional end values support strong development margins, often exceeding 25-30% profit on cost, which in turn provides a comfortable buffer for the additional cost of mezzanine finance. A project that achieves 30% profit on cost can comfortably absorb a blended finance cost of 0.85% per month while still delivering excellent returns to the developer.
The scarcity of development sites in Westminster means that opportunities, when they arise, often require rapid execution. Developers who have pre-arranged mezzanine facilities or established relationships with mezzanine providers can move more quickly than competitors who need to raise additional equity. This speed advantage is particularly relevant for auction purchases, off-market acquisitions, and situations where a vendor is motivated by certainty and speed of completion.
Westminster's planning environment also favours mezzanine-funded structures. The borough's conservation areas, listed buildings, and strict planning policies mean that many development projects involve complex refurbishment and conversion rather than straightforward new-build construction. These projects often carry higher risk profiles that make senior lenders cautious about leverage, creating a natural role for mezzanine finance to fill the gap between what the senior lender will provide and what the developer needs.
Westminster Development Snapshot
Typical Westminster Mezzanine Project
A common mezzanine-funded project in Westminster involves the acquisition and conversion of a period building from commercial or mixed use into high-end residential apartments. The developer acquires the property, obtains planning consent for change of use and refurbishment, then completes the conversion over 12-18 months. The senior lender provides acquisition and construction finance at 65% LTC, the mezzanine lender provides an additional 20% LTC, and the developer contributes 15% equity. Completed units are sold individually, with proceeds used to repay the mezzanine first (after the senior), then the developer receives their profit share.
