Property Portfolio Auditing

For companies with a property portfolio, whether they be a corporate occupier or a landlord, it is accepted that property does not administer itself.

Marston Associates has a wealth of experience in identifying and recovering monies by reviewing past records, ensuring that there are no missed profit opportunities. We have worked successfully with well-known property companies, multiple retailers and the like. In fact, we have never failed in making recoveries for our clients when undertaking an audit.

Furthermore, our fees are on a no recovery no fee basis, so there is no risk to you if you instruct us. An independent review with our specialist expertise will enhance your profitability and provide key learnings going forward.

How it works

Fundamental to our audits is assembling historic payment information and marrying it with its source; typically a supplier agreement, lease, contract, order or invoice. Applying our experience of how internal processes work (or fail) and expertise in contract interpretation, in tandem with financial data, we analyse information en masse, which in turn highlights suspect transactions.

Management must be confident that all charges are correct. In times of changing legislation, market practices and trading environments, there is a need for greater focus to detail by Finance and Property Directors, Managers and Administrators.

Effective property management can be hindered for many reasons, including:

  • Refocusing of priorities
  • Changes in personnel
  • Breakdown of processes
  • Database upgrades
  • Lack of resource
  • Limited expertise in smaller operations

Our services are performed in a non-intrusive manner and require minimal interaction with the client. Confidentiality is respected at all times and we comply with Data Protection legislation.


The scope of an audit is agreed with the client in advance of an assignment. If a client has concerns regarding particular areas of the portfolio, these can be highlighted; e.g. service charges, business rate liabilities etc. This also ensures that there is no duplication of services which may already be in place.

Areas of Investigation:

  • Rent, service charge and insurance payments
  • Rent, service charge and insurance receivable
  • Business Rates liabilities
  • Council Tax liabilities
  • Energy
  • Water
  • Insurance cover and claims
  • Facility suppliers and contractors
  • VAT recovery and accounting
  • Compensation and Taxation

Monies can be recovered from:

  • Landlords
  • Managing agents
  • Subtenants
  • Energy Companies
  • Water Authorities
  • Customs and Excise
  • Local Authorities
  • Maintenance Contractors
  • Service Providers
