Mezzanine Finance
for Westminster Developers

Mezzanine finance is a specialist product that sits between senior debt and developer equity in the capital stack. Structuring it correctly requires a broker who understands intercreditor dynamics, can coordinate with your senior lender, and has access to mezzanine providers who are actively deploying capital. We arrange mezzanine facilities from debt funds, family offices, and specialist lenders with genuine appetite for Greater London developments. For a typical Westminster development with a GDV around £3.2M, mezzanine could reduce your cash equity requirement from approximately £1.1M to as little as £474,000.

The mezzanine market is less transparent than senior development finance. There is no comparison website, limited published rate information, and each provider has specific criteria around minimum deal size, geographic focus, and acceptable senior lender partners. As specialist brokers, we have established relationships with mezzanine providers who can move quickly and are comfortable lending in Westminster and the wider Greater London area.

Getting the capital stack right from the outset is critical. The wrong mezzanine structure can create cash flow problems, governance friction, or exit complications that cost you more than the additional leverage is worth. Submit your project and our team will model the optimal capital structure for your development.

The live Westminster City Council planning register currently shows 308 residential applications awaiting decision in Westminster, together proposing 12 units. The largest — at 17 Belgrave Square London SW1X 8PG — proposes 5 units. That pipeline is a useful gauge of both local competition and lender familiarity with Westminster schemes.

On a representative 10-unit Westminster scheme (~£7.9M GDV at the local median), mezzanine typically bridges the gap between 65% and up to 85% LTGDV — around £1.6M of additional leverage that would otherwise be developer equity.

We source several types of mezzanine capital across Greater London: traditional second-charge mezzanine that layers behind your senior development finance facility, stretched senior products where a single lender provides both tranches (eliminating intercreditor complexity), profit-share mezzanine where the provider takes a percentage of development profit instead of fixed interest, and preferred equity structures that sit between debt and true equity in the waterfall.

Each structure has different implications for your project governance, cost profile, and exit mechanics. Second-charge mezzanine typically costs 12-18% per annum but preserves your control. Profit-share structures reduce your cash costs during the build phase but can be more expensive if the scheme performs well. Stretched senior products simplify the legal structure but may carry a premium over a two-lender arrangement. We advise on the optimal approach for each Westminster development based on its specific economics.

For larger schemes, we also arrange equity and joint venture capital as an alternative to, or alongside, mezzanine debt. The right choice depends on your equity position, return expectations, and appetite for sharing control of the development process.

Mezzanine capital for Westminster schemes comes from a distinct pool of funders — specialist banks such as OakNorth, Shawbrook, and Aldermore alongside dedicated mezzanine houses. The mezzanine slice sits behind the senior facility under an intercreditor agreement, is measured against loan-to-cost (LTC) as well as LTGDV, and drawdown timing is negotiated alongside the senior lender's. Where mezzanine doesn't fit, equity finance or a second charge bridging loan can close the same gap with a different risk allocation.

Mezzanine interest rates typically range from 12% to 18% per annum, with interest usually rolled up rather than serviced monthly. Arrangement fees are 2-3% of the mezzanine facility. While these costs are higher than senior development debt, the mezzanine is funding a smaller portion of the capital stack, and the blended cost of senior plus mezzanine is often comparable to alternative structures that achieve similar leverage.

The key calculation is whether the additional leverage creates sufficient incremental return to justify the cost. If senior debt funds 65% of costs and mezzanine stretches this to 85%, you are using 20% more debt to free up 20% of equity. That freed equity can be deployed into another project, effectively doubling your development capacity. For developers in Westminster with pipeline opportunities, this capital efficiency can be transformational.

We model the full capital stack for every mezzanine enquiry, showing you the blended cost of finance, the impact on scheme profit, and the comparison with alternative structures (higher equity contribution, stretched senior, or JV equity). This analysis ensures you make an informed decision based on your project's specific numbers.

Mezzanine lenders assess your scheme through a similar lens to senior lenders but with additional focus on the developer's experience and the profit margin in the deal. Most providers require a minimum net development profit of 18-20% on cost after all finance charges, giving them comfort that the scheme can absorb cost overruns or market adjustments without threatening their position. A strong track record of delivering comparable schemes is important for securing the best mezzanine terms.

The senior lender must be mezzanine-friendly. Not all development finance lenders accept subordinated debt behind their facility, and those that do typically require an approved intercreditor agreement. We identify mezzanine-friendly senior lenders at the outset of the process, avoiding the costly scenario of agreeing senior terms only to discover the lender will not accept mezzanine.

Minimum mezzanine facility sizes are typically £200,000-£500,000, with some providers requiring larger minimum investments. For smaller schemes where mezzanine is not available, alternative approaches include stretched senior products, bridging finance for the gap, or restructuring the deal to work with a higher equity contribution.
