Common questions
How is development finance calculated in the UK?
Most senior lenders size a facility as a percentage of Gross Development Value (LTGDV) — typically 60% to 70% for senior debt, up to 75% for stretched senior, and up to 85–90% when combined with mezzanine. Our Development Finance Calculator walks through the sizing step by step.
How much deposit do I need for UK development finance?
For a scheme with a 65% LTGDV senior loan, expect to inject around 30–35% of total project cost as equity, with the facility funding build and part of land. Precise deposit depends on your land basis, build cost, target LTGDV and contingency — our calculator models it.
Can you get 100% development finance in the UK?
Pure 100% senior finance is rare and usually restricted to very strong sponsors on prime assets. Most developers stack senior + mezzanine + equity, or bring in a JV partner, to reach 85–95% of total cost. None of these are truly 100% senior.
How much will a bridging loan cost me?
The real cost of a UK bridging loan is monthly interest + arrangement fee (usually 1.5–2% of facility) + exit fee (0–1%) + legals + valuation. Our Bridging Loan Cost Calculator sums all of these for an all-in figure.
