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
Hounslow offers good scope for permitted development conversions, with conservation areas covering only 14% of the area. Class MA (commercial to residential) conversions are particularly popular and can be funded from 7% per annum through specialist PD lenders.
Pre-Application Advice
Hounslow 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.
Hounslow Conservation Areas
Conservation coverage in Hounslow is relatively low at 14%, meaning most development sites are outside conservation areas. This simplifies the planning process and gives developers more flexibility in design and materials.
The Planning-Finance Timeline
A typical Hounslow development follows this planning-to-finance sequence:
1. Pre-application (4-8 weeks): Engage with Hounslow 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:
