How Planning Status Affects Your Finance

Full Planning Permission

This is the gold standard for lenders. With full planning in place, you'll access the widest range of lenders and the most competitive rates (from 6.5% p.a. for senior debt). Most mainstream development finance requires full planning before drawdown.

Outline Planning Permission

Some lenders will consider outline planning, particularly for larger sites where detailed design is still being finalised. Expect slightly higher rates (1-2% premium) and lower LTV limits. Reserved matters must be addressed before construction can begin.

Permitted Development (PD) Rights

PD rights in London are limited in conservation areas, which cover 42% of the borough. Developers should check for Article 4 directions that may restrict specific PD rights. Outside conservation areas, Class MA (commercial to residential) remains available.

Pre-Application Advice

London Council offers pre-application consultation services. For development finance, a positive pre-app response strengthens your application to lenders, as it demonstrates the planning authority's likely support.

London Conservation Areas

With 42% conservation coverage, London has significant heritage character. Key considerations for developers in conservation areas:

Design standards: Conservation officers will scrutinise external appearance, materials, and massing

Listed building consent: Required in addition to planning permission for listed buildings

Extended timelines: Allow 3-6 months additional time for heritage planning processes

Material costs: Period-appropriate materials can add 15-30% to build costs — ensure your finance facility accounts for this

The Planning-Finance Timeline

A typical London development follows this planning-to-finance sequence:

1. Pre-application (4-8 weeks): Engage with London Council for initial feedback 2. Full application (8-13 weeks): Submit planning application with supporting documents 3. Decision (target 8 weeks for minor, 13 weeks for major applications) 4. Finance application (can run in parallel from pre-app stage) 5. Valuation (1-2 weeks after planning granted) 6. Legal and drawdown (2-4 weeks)

Total timeline from pre-app to first drawdown: approximately 4-6 months for straightforward schemes.

Getting Finance Before Planning

Some developers need finance to acquire a site before planning is granted. Options include:

Land bridging: Short-term bridge to acquire the site while planning is progressed

JV equity: Equity partner funds the land acquisition with planning uplift potential

Conditional purchase: Negotiate a conditional contract subject to planning
