Commercial Mortgage Rates Explained: How to Get the Best Deal
Understanding how commercial mortgage rates work can save you thousands. Learn what affects your rate and how to secure the most competitive terms.
Commercial mortgage rates vary significantly between lenders and depend on multiple factors. Understanding how rates are calculated and what you can do to improve your offering is key to getting the best deal.
How Commercial Mortgage Rates Work
Commercial mortgage rates are typically expressed as a margin above the Bank of England base rate or a reference rate (such as SONIA). The margin reflects the lender's assessment of risk.
Fixed vs Variable Rates
Fixed rates provide certainty — your monthly payment stays the same for the fixed period (typically 2–5 years). This makes budgeting easier but means you won't benefit if rates fall.
Variable rates can go up or down with the market. They often start lower than fixed rates but carry the risk of increasing payments.
Factors That Affect Your Rate
1. Loan-to-Value (LTV)
The lower your LTV, the better the rate. A 50% LTV mortgage will typically get a better rate than a 75% LTV mortgage because the lender's risk is lower.
2. Property Type
Standard commercial properties (offices, shops, industrial units) get better rates than specialist properties (care homes, petrol stations, leisure venues).
3. Business Financials
Strong, consistent trading history and healthy profits will secure better rates than a new or financially stretched business.
4. Debt Service Coverage Ratio (DSCR)
Lenders typically require rental or business income to cover 125–145% of the mortgage payments. The stronger this ratio, the better the rate.
5. Credit History
Both business and director personal credit history are assessed. Clean credit files lead to better rates.
How to Get the Best Rate
- Use a whole-of-market broker — different lenders have different appetites and rate cards. A broker compares them all.
- Reduce your LTV — a larger deposit or additional security can significantly reduce your rate.
- Prepare strong financials — up-to-date accounts, management accounts, and projections strengthen your application.
- Consider a longer fixed period — some lenders offer better rates for 5-year fixes than 2-year fixes.
- Demonstrate strong rental coverage — if the property is investment, higher rental income relative to the mortgage payment improves terms.
Typical Rate Ranges
- Prime commercial mortgages (low LTV, strong borrower): Bank of England base rate + 1.5–3%
- Standard commercial mortgages: Base rate + 3–5%
- Specialist commercial mortgages (higher risk, complex property): Base rate + 5–8%
These are indicative ranges only. Actual rates depend on your specific circumstances and prevailing market conditions.
