Open Market

The open market is made up of different ‘afford-abilities’, so, in linking the review to “open market rent” (OMR) ‘open’ means everyone and anyone (A).

As indicative or comparable evidence, a new letting to an inexperienced first-time tenant at a rent that might amaze is as valid as any hard-driven bargain by a multiple retailer with hundreds of branches. So, since rents in the open market are unregulated, any tenant committing to a review to OMR is exposing its business to all manner of risks beyond its control (a situation that can strain compliance with the Turnbull report on internal control and risk management, to safeguard shareholders' investment and the company's assets). That is the nature of the system; and when tenants choose to agree to a rent review to the open market rent it is implicit the tenant is agreeing to the underlying purpose and overriding objective: namely to enable the landlord to obtain the open market rent at the valuation date per terms of the tenancy, not for the tenant to expect to pay any less.

Similarly, since, in the open market, different landlords are likely to have different investment performance strategies, risks also apply to the landlord’s investment. Hence, the only way the actual landlord and actual tenant can have any control over the direction of the rental relationship is by recording their requirements in the lease, per the rent review guidelines.

Hoffmann LJ commented on the concept of the open market in a capital transfer tax case, IRC v Gray [1994] STC 360:

"It cannot be too strongly emphasised that although the sale is hypothetical, there is nothing hypothetical about the open market in which it is supposed to have taken place. The concept of the open market involves assuming that the whole world was free to bid, and then forming a view about what in those circumstances would in real life have been the best price reasonably obtainable …"
