PurposeIn the context of the financial crash and the commercial property market downturn, the purpose of this paper is to examine the basis of valuation used in the UK commercial property lending process. Post‐crisis there is discussion of countercyclical measures, including the monitoring of asset prices; however there is no consideration of a different approach to property valuation. This paper questions this omission, given the role that valuations play in the bank regulatory process.Design/methodology/approachThe different bases of valuation available to lenders within international valuation standards are identified as market value (MV), mortgage lending value (MLV) and investment value (IV), with MV being the most used in the UK. Using the different bases in the period before the financial crisis, the UK property market is modelled at a national office, retail and industrial/warehouse sector level to determine the performance of each alternative valuation basis within the context of countercyclical pressures on lending.FindingsBoth MLV and IV would have produced lower valuations than MV, although there are some practical issues involved in adopting the different bases for the bank lending.Originality/valueThe use of a different valuation basis could provide lenders with tools for more informed and prudent lending.
