What is Development Finance?
Development finance is a specialist form of property funding designed to support ground-up construction, major conversions, and heavy refurbishment projects. Unlike a standard mortgage, which advances a lump sum against the current value of a completed property, development finance is structured around the projected value of your finished scheme, known as the gross development value (GDV). Funds are released in stages as construction progresses, with each drawdown verified by an independent monitoring surveyor.
For Chelsea developers, this type of funding is essential because projects in the Royal Borough of Kensington and Chelsea (RBKC) carry unique characteristics that mainstream lenders are not equipped to handle. The conservation area restrictions, listed building considerations, party wall complexities in terraced streets, and the high absolute values involved all require lenders with specialist underwriting expertise. A typical Chelsea development might involve converting a period townhouse on a garden square into luxury apartments, excavating a multi-storey basement beneath a King's Road property, or constructing a boutique residential scheme on a rare infill plot near Chelsea Harbour.
Development finance providers assess your project holistically. They evaluate the site, the planning consent, the build programme, the contractor, the professional team, your experience, and crucially the end values achievable in the Chelsea market. Because Chelsea consistently commands some of the highest price-per-square-foot values in London, well-structured schemes with realistic appraisals tend to attract competitive terms from lenders who understand the local market dynamics.
As specialist Chelsea development finance brokers, we work with over 100 lenders including challenger banks, private credit funds, family offices, and institutional investors. This breadth of panel means we can match your project to the most suitable lender, whether you need the lowest rate, the highest leverage, the fastest completion, or a lender experienced with a particular building type or planning route.
Types of Development Finance
Different capital structures to suit your Chelsea project's requirements and your appetite for leverage.
Senior Debt
The primary layer of development funding, secured by a first charge over the development site. Senior debt typically provides up to 70% of total project costs (LTC) and up to 65% of the gross development value (GDV). This is the most cost-effective form of development finance, with rates starting from 0.65% per month for experienced Chelsea developers. Senior lenders have priority in any enforcement scenario, which is why they offer the lowest rates.
Stretched Senior
A single-lender solution that provides higher leverage than standard senior debt, reaching up to 80% of total project costs. Stretched senior finance combines what would traditionally be the senior and mezzanine tranches into one facility from a single lender. This simplifies the capital structure, avoids intercreditor complications, and can be faster to arrange. Rates are higher than standard senior but lower than a blended senior-plus-mezzanine structure.
Mezzanine Finance
A second charge facility that sits behind your senior development lender, bridging the gap between what senior debt covers and your total project costs. Mezzanine finance can take the combined loan-to-cost up to 90%, significantly reducing your personal equity contribution. The mezzanine lender takes greater risk than the senior lender, which is reflected in higher rates, typically 1.0% to 1.75% per month. Interest is rolled up and repaid on project completion.
Development Equity
Joint venture equity partnerships where an investor provides the equity portion of your capital stack, or even funds up to 100% of total project costs, in exchange for a share of the development profit. This structure allows developers to take on larger schemes without committing all of their own capital. Profit share arrangements typically range from 20% to 50% depending on how much equity the partner contributes and the risk profile of the scheme.
How Development Finance Works
From initial enquiry to project completion, here is how the development finance process works for Chelsea projects.
Application & Appraisal
Submit your project details including site information, planning status, build costs, and projected end values. We prepare a comprehensive appraisal and present your scheme to suitable lenders from our panel of 100+ providers. Indicative terms are typically available within 24 hours.
Valuation & Due Diligence
Once you accept indicative terms, the lender instructs an independent RICS valuation of the site and a review of your development appraisal. The valuer assesses the current market value, the projected GDV based on comparable evidence in Chelsea, and the reasonableness of your build cost assumptions.
Legal & Documentation
Both your solicitor and the lender's solicitor carry out legal due diligence on the title, planning consent, building regulations, and any site-specific matters such as party wall awards or listed building consent. The facility agreement, charge documents, and drawdown schedule are prepared.
Initial Drawdown
On completion of the legal process, the first tranche of funding is released. This typically covers the site acquisition cost and any day-one professional fees. The arrangement fee is usually deducted from this initial drawdown. Your project account is set up for future drawdown requests.
Staged Drawdowns
As construction progresses, you request further drawdowns against the agreed build schedule. Each request is verified by the appointed monitoring surveyor who visits the site to confirm that the works completed match the stage claimed. Funds are typically released within 3 to 5 working days of QS certification.
Monitoring & Oversight
Throughout the build programme, the monitoring surveyor conducts regular site visits to track progress against the agreed timeline and budget. Any material changes to the specification, programme, or costs are discussed with the lender. This ongoing oversight protects all parties and keeps the project on track.
Exit & Repayment
On completion of the development, you execute your planned exit strategy, whether that is selling units on the open market, refinancing onto long-term investment mortgages, or a combination of both. The development finance facility, including all rolled-up interest and fees, is repaid in full from the exit proceeds.
The Capital Stack
Understanding how different layers of funding combine to finance your Chelsea development project.
Developer Equity
10-25% of total costs
Mezzanine Finance
15-20% of total costs
Senior Debt
60-70% of total costs
Senior Debt (First Charge)
The foundation of your capital stack. Senior debt is secured by a first legal charge over the development site and typically represents 60-70% of total project costs. As the lowest risk layer, it commands the lowest interest rates starting from 0.65% per month. In an enforcement scenario, the senior lender is repaid first.
Mezzanine Finance (Second Charge)
Sits between your senior debt and equity, filling the funding gap. Mezzanine lenders accept a subordinated position behind the senior lender, taking higher risk in exchange for higher returns. This layer can take your combined borrowing up to 90% of total costs, reducing the equity you need to invest.
Developer Equity
Your personal contribution to the project, whether from cash, existing property equity, or a JV equity partner. The equity portion represents your skin in the game and absorbs the first losses if the project underperforms. Minimising equity through leverage maximises your return on capital but increases risk.

Eligibility Requirements
What lenders look for when assessing your Chelsea development finance application.
Development Experience
Most lenders prefer developers with at least one completed project. However, first-time developers are welcome provided they have assembled a strong professional team including an experienced contractor and project manager. We have dedicated lenders who actively support first-time developers.
Planning Status
Full planning permission or permitted development rights should ideally be in place. Some lenders will consider applications where planning is pending or subject to a positive pre-application response from RBKC, particularly for established developers.
Minimum Scheme Size
Most development finance lenders have a minimum facility size of £500,000, though some will consider smaller projects from £250,000. There is no maximum, and we regularly arrange facilities of £10 million to £50 million or more for larger Chelsea schemes.
Exit Strategy
A clear and credible exit strategy is essential. This is typically the sale of completed units on the open market or refinancing onto investment mortgages. Lenders will want to see comparable evidence supporting your projected sales values and realistic timelines for achieving them in the Chelsea market.

Development Finance FAQs
Common questions about development finance for Chelsea property projects.
For Chelsea development projects, you can typically borrow up to 70% of total costs (loan-to-cost) and up to 65% of the gross development value (GDV). Facilities generally range from £500,000 to £50 million or more. The exact amount depends on your track record as a developer, the specifics of your scheme, planning status, and the strength of your exit strategy. Chelsea's strong property values and reliable end-buyer demand mean lenders often view schemes here favourably, which can translate into more competitive leverage.
Development finance rates for Chelsea projects currently start from 0.65% per month for experienced developers with straightforward schemes. Rates typically range from 0.65% to 1.25% per month depending on the loan-to-cost ratio, your experience level, project complexity, and overall risk profile. Interest is usually rolled up into the facility and repaid on project completion rather than serviced monthly, which preserves cash flow during the build. We compare terms across 100+ specialist lenders to secure the most competitive rate for your specific project.
We provide indicative terms within 24 hours of receiving your project details. From formal application to initial drawdown, the typical timeline is three to four weeks for straightforward schemes. Complex projects involving conservation area consents, party wall agreements, or basement construction in Chelsea may require four to six weeks. Where speed is essential, such as for a site acquisition with a tight exchange deadline, we have access to lenders who can complete in as little as seven working days.
Yes, first-time developers can access development finance for Chelsea projects. Lenders will want to see a credible professional team in place, including an experienced contractor, qualified architect, and realistic project appraisal. You may face slightly higher rates (typically 0.85% to 1.1% per month) and lower leverage (55-60% LTC) compared to experienced developers. We have several lenders on our panel who actively support first-time developers, particularly for smaller conversion and refurbishment projects where the risk profile is more contained.
For standard senior development finance, you will typically need to contribute 30% to 40% of total project costs as equity. This can come from personal cash, equity in existing properties, or a combination of both. If you have a strong track record, some lenders will accept as little as 25% equity. By layering mezzanine finance on top of senior debt, you can potentially reduce your cash equity requirement to as little as 10% of total costs, though this comes at a higher blended interest rate.
We arrange finance for the full spectrum of Chelsea development projects: ground-up new build residential schemes, commercial-to-residential conversions under permitted development or full planning, period property refurbishments and modernisations, basement excavations and lateral extensions, mixed-use developments with retail or office at ground floor, HMO and multi-unit freehold block conversions, and luxury apartment fit-outs. Chelsea's mix of Georgian terraces, Victorian mansion blocks, and modern waterfront developments means specialist local knowledge is essential when structuring finance.
Development finance is released in stages aligned to your construction programme rather than as a single lump sum. The first drawdown typically covers the site acquisition. Subsequent tranches are released against a Quantity Surveyor's certification that confirmed works match the agreed build schedule. Your appointed monitoring surveyor will visit the site at regular intervals, typically monthly, to verify progress before each drawdown is authorised. This staged approach means you only pay interest on funds actually drawn, reducing your overall finance cost.
The main fees for development finance include: an arrangement fee of 1% to 2% of the gross facility, typically deducted from the initial drawdown; an exit fee of 0% to 1% of the loan amount, though many lenders now offer zero exit fee products; valuation and monitoring surveyor fees which vary by scheme size but typically range from £3,000 to £10,000; and legal fees for both your solicitor and the lender's solicitor. We provide a comprehensive fee schedule upfront so you can factor all costs into your project appraisal from day one.
Most lenders require either full planning permission or permitted development rights to be in place before they will formally offer terms. However, some specialist lenders will consider pre-planning applications where you have a strong likelihood of obtaining consent, particularly for schemes with positive pre-application responses from the Royal Borough of Kensington and Chelsea planning department. Having planning in place before you apply will give you access to the widest range of lenders and the most competitive rates.
The primary exit strategies accepted by development finance lenders are: sale of completed units on the open market, which is the most common and preferred route given Chelsea's strong end-buyer demand; refinance onto a long-term buy-to-let or investment mortgage if you plan to retain the completed units as rental properties; and a combination of partial sales and partial retention. Lenders will assess the viability of your exit strategy as part of their underwriting, looking at comparable sales evidence, market conditions, and realistic timelines for achieving sales in the Chelsea market.
While no single lender provides 100% of project costs through debt alone, it is possible to structure funding that covers 100% of costs by combining senior debt (up to 70% LTC), mezzanine finance (an additional 15-20% LTC), and development equity for the remaining balance. Alternatively, joint venture equity partners may fund the entire project in exchange for a share of the profits, typically 30% to 50%. These structures are best suited to experienced developers with proven track records and strong schemes in desirable Chelsea locations.
Development finance differs from a standard mortgage in several fundamental ways. It is drawn down in stages against construction progress rather than as a single advance. Interest is typically rolled up and repaid at the end of the project rather than serviced monthly. The facility is short-term, usually 6 to 36 months, and is secured against both the current site value and the projected end value (GDV). Lenders assess the viability of the entire development scheme, not just the borrower's income. Development finance also involves ongoing monitoring by a Quantity Surveyor throughout the build programme.
