Development finance for permitted development

Last reviewed: 14 June 2026

Development finance for permitted development funds conversions that use PD rights rather than full planning permission. Common examples include office-to-residential and agricultural-to-residential. Lenders assess the prior approval, conversion plans, costs, GDV, exit and borrower experience.

What permitted development means

Permitted development (PD) rights allow certain works and changes of use without needing full planning permission. They are defined in the Town and Country Planning Order. Common PD rights include office-to-residential conversions under Class E to C3, and agricultural buildings to residential subject to certain conditions.

Prior approval vs full planning

While PD removes the need for a full planning application, some PD rights still require prior notification or prior approval from the local authority. Prior approval focuses on specific matters such as transport, contamination or hazards rather than general design and impact. This is faster but still requires documentation.

Common PD conversion types

Typical PD conversions include office-to-residential, retail-to-residential, storage-to-residential and agricultural buildings-to-residential. Each has specific conditions such as size limits, location requirements or structural conditions. Lenders will check the particular PD rights that apply to ensure the project qualifies.

What lenders check for PD schemes

Lenders verify the PD rights apply, that prior approval has been or will be obtained, and that the conversion costs and GDV are realistic. They also assess structural condition, market demand for the converted use and the exit route. More conservative lending may apply due to the specific regulatory pathway.

Risks specific to PD projects

PD projects may face restrictions on future modifications, limited ability to change the scheme if circumstances change, or challenges if building condition is worse than anticipated. Market appetite for converted PD units may also be uncertain. These risks may affect lending terms or require contingency for adaptive scenarios.

Exit by sale or refinance

The exit for PD development is typically sale of the completed units to end buyers or investors. Lenders assess market conditions and comparable evidence to confirm realistic exit pricing. Refinance exit may also be possible if the borrower intends to retain and let the units.

Frequently asked questions

Not exactly. PD removes the need for a full planning application, but prior approval or notification to the council is still usually required.

Some do, because PD schemes carry specific risks such as restricted conditions and limited scope for changes.

In some areas, local authorities have issued Article 4 directions removing certain PD rights. Check this before proceeding.
