Mortgage guide
Commercial mortgage for factory
A commercial mortgage for a factory is used to purchase, refinance, or raise capital against manufacturing and production facilities, where lending decisions are driven by a combination of asset risk, operational use, and environmental exposure. 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.
Commercial mortgage for factory
A commercial mortgage for a factory is used to purchase, refinance, or raise capital against manufacturing and production facilities, where lending decisions are driven by a combination of asset risk, operational use, and environmental exposure. 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:
- 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.

Frequently asked questions
What is a commercial mortgage?
A commercial mortgage is an asset-backed loan secured against commercial, semi-commercial or large-scale investment property. Lenders assess it on income sustainability and asset risk rather than personal income multiples, and pricing is set case by case, usually as a margin over Bank Rate.
What deposit does a commercial mortgage need?
On the cases we arrange, investment property typically needs a deposit of 25% to 40%. Owner-occupied retail lending can reach 80% loan-to-value, and on medical, dental and pharmacy transactions we currently see a number of options at up to 100% of an MV3 valuation, so no deposit may be needed on the right case. That reflects our experience of the current market, not a standard lender rule.
How much can I borrow on a commercial mortgage?
The lower of two caps. The first is affordability: in our experience investment property needs stressed rental coverage of 125% to 145%, and an owner-occupier's business EBITDA must cover the repayments 1.25 to 2 times. The second is loan-to-value, which in our experience runs at 60% to 75% for most sectors.
Can I get an interest-only commercial mortgage?
Yes, selectively. In our experience interest-only commercial lending typically goes up to 75% loan-to-value, through specialist and challenger lenders, where the income comfortably covers the debt and the exit is credible. High-street lenders generally require capital repayment.
How is commercial mortgage affordability stress-tested?
For investment property, on the cases we arrange the rent must cover 125% of the interest at a stressed rate, rising to 145% for higher-rate taxpayers or weaker leases. As an illustration, with interest modelled at a 5% stress rate, 125% cover means the rent must support interest at an effective 6.25%, and 145% cover at 7.25%. The stress rate is the lender's own assessment rate, which can differ from the product's pay rate and depends on the lender and the product, so an adviser checks the lender's current assessment rate. Owner-occupied property is tested on the business's profit instead.
