Factory lending sits within the industrial sector but is treated more cautiously than standard warehouses or light industrial units due to historical land use and potential contamination risks. ### Loan-to-Value and Lender Appetite Factory premises can often achieve competitive leverage when the asset and business are strong, but maximum loan-to-value is more sensitive to risk factors than for generic industrial property. LTV is influenced by: - Nature of manufacturing activity (light vs heavy industrial) - Historic and current site use - Environmental risk profile - Trading strength of the occupier (for owner-occupiers) - Lease structure and tenant covenant (for investment assets) ### Environmental Due Diligence and Groundsure Searches A critical component of factory lending is environmental due diligence. Most commercial mortgage lenders will require a Groundsure environmental search as part of the legal and valuation process to assess contamination and land-use risk. Key points lenders consider: - The Groundsure report is graded (e.g. Pass, Medium, or Fail) based on environmental risk indicators - Some lenders will only proceed where the Groundsure search returns a clear Pass - A Medium or below result is often unacceptable to mainstream lenders Where a Groundsure result is Medium or adverse, lending typically shifts into specialist commercial finance, which may involve: - Reduced loan-to-value - Higher interest rates - Additional reports (Phase 1 or Phase 2 environmental assessments) - More conservative exit assumptions This requirement is particularly common for factories with historic manufacturing use, chemical processes, heavy machinery, or proximity to former industrial land. ### Affordability and Credit Assessment Affordability assessment depends on property use with [commercial mortgages](https://mortgagelane.com/mortgages/commercial-mortgages): - Owner-occupied factories are underwritten on the trading performance of the business, with lenders reviewing historic accounts, management figures, and cash flow sustainability. - Investment factories are assessed primarily on rental income using Debt Service Coverage Ratios (DSCR), with stress testing applied. In both cases, lenders focus on maintainable income rather than peak performance. ### Valuation Methodology Factory valuations may be: - Yield-based where the property is income-producing as a business or let on a commercial lease to a corporate. - Vacant possession-led for owner-occupied facilities, often assuming a 90-180 day marketing period, adjusted for site specificity and alternative use potential Specialised factories with limited alternative use are valued more conservatively. A commercial mortgage for a factory combines standard industrial lending principles with enhanced environmental scrutiny. Groundsure searches are mandatory, and many lenders will only lend where the result is a clear Pass. Where environmental risk is flagged as Medium or worse, funding usually requires specialist lenders, often at lower leverage and higher cost. Understanding environmental risk early is essential to structuring factory mortgages efficiently and avoiding delays or declined applications. ## Talk it through with an adviser Speak to a Mortgage Lane adviser about your circumstances and the next steps.
