Permitted Development and Refurbishment Finance
PD rights let you convert without a full planning application, and lenders will fund it. But 'permitted' is doing quiet work in that sentence, and underwriters want specific evidence before they rely on it.
Why PD projects sit in heavy refurbishment
Class MA office-to-residential conversions, agricultural conversions under Class Q, extensions under householder PD: functionally these are conversions, so lenders treat them as heavy refurbishment regardless of the planning shortcut. Facilities are sized against GDV, works draw in stages, and the underwrite examines the planning position as closely as a full application, just with different documents.
What lenders accept in place of a planning grant
- Prior approval decisionFor PD classes that require it (Class MA among them), the local authority's prior approval notice is the document lenders lend against. Most want it granted before completion; some will exchange with completion conditional on it.
- Lawful development certificateNot mandatory for PD, but the gold standard for an underwriter: the council's formal confirmation that the proposed use is lawful. Where timelines allow, obtaining an LDC widens the lender panel and sharpens pricing.
- Planning consultant's opinionFor clean cases some lenders will proceed on a professional opinion confirming the PD rights apply, particularly where the borrower's team has PD conversions in its track record.
PD-specific risks the underwriter will probe
- Article 4 directions: councils can and do remove PD rights locally. The title search will surface this; check before you exchange, not after.
- Condition creep: prior approval can carry conditions (noise, contamination, transport) whose discharge costs money and time. Budget both.
- Space and light standards: PD residential conversions must meet national space standards and adequate natural light requirements. Schemes that shave these fail at prior approval, and lenders know it.
- Exit valuation basis: the GDV should reflect the finished residential units against local comparables. A PD conversion in a weak residential location can be lawful, buildable and still unviable.
Sequencing the finance around prior approval
The clean sequence: agree the purchase, submit for prior approval, arrange the facility in parallel so valuation and legals run while the council's 56-day clock runs, then complete once the notice lands. Where the vendor will not wait, a standard bridge can buy the building first, refinancing into the refurbishment facility once approval is granted. It costs more; sometimes the deal is worth it. We model both routes so the decision is arithmetic, not hope.
