Due Diligence Checklist for Commercial Property Buyers

Hand holding a pen over a checklist with ticked boxes.

Buying a commercial property is a major investment. Whether you’re expanding your business, acquiring a site for development, or entering the commercial market as an investor, undertaking proper due diligence is vital to ensure you’re making a sound purchase.

This guide outlines the key steps commercial property buyers should take before completing a transaction — covering legal, financial, and physical checks. Following this checklist could save you from costly surprises down the line.

1. Legal Due Diligence

Before signing any contracts, your solicitor should conduct comprehensive legal investigations into the property:

  • Title and Ownership: Confirm legal ownership and title boundaries via the Land Registry. Check for restrictive covenants, easements or rights of way.
  • Planning and Use Class: Review current planning permissions and any outstanding enforcement notices. Confirm the property’s use class (e.g., E, B2) and ensure it suits your intended use.
  • Tenancies and Lease Terms: Examine all existing leases or licences to occupy. Note rent levels, break clauses, rent review dates, and obligations (e.g., repairs).
  • Environmental checks: agree appropriate searches and investigations with your solicitor and surveyor. Asbestos may require a separate specialist assessment.
  • Building Regulation Compliance: Ensure any alterations or extensions comply with building regulations and were approved.

2. Financial Due Diligence

Understanding the financial health and viability of the property is crucial:

  • Valuation: obtain advice appropriate to your purpose, and distinguish an agent’s market appraisal from any formal valuation required by a lender.
  • Yield and Rental Income: If the property is tenanted, analyse rental income, occupancy rates, and service charge recoverability.
  • Running Costs: Review utility costs, business rates, and service charges to assess total ongoing costs.
  • Tax Implications: Consider Stamp Duty Land Tax (SDLT), VAT status, and potential capital gains implications.

3. Physical and Structural Due Diligence

Even visually sound buildings can hide issues. A thorough survey is essential:

  • Building survey: ask a suitably qualified surveyor to recommend the appropriate inspection and scope for the property and intended use.
  • Services and Utilities Check: Confirm heating, electrics, water and internet infrastructure are in working order.
  • Asbestos and Fire Safety: Ensure compliance with health and safety standards, including asbestos reports and fire risk assessments.

4. Commercial and Operational Considerations

Aligning the property with your business goals is just as important:

  • Location and Accessibility: Evaluate local amenities, transport links, and footfall.
  • Market Demand: Assess demand in the area for your intended use — whether retail, office or industrial.
  • Development Potential: If considering redevelopment or change of use, consult planners and architects early.

5. Final Steps Before Exchange

  • Ensure your solicitor has addressed all legal and technical queries.
  • Review heads of terms and the sale contract carefully.
  • Confirm finance arrangements are in place.
  • Set a realistic completion date.
