Can Backdated Rent Affect a Rent Review in a Commercial Lease?

Summary

  • A backdated rent review occurs when a landlord reviews rent after the scheduled date but applies any increase from the original review date. 
  • This means tenants must pay the difference between old and new rent for the past period, often as a lump sum and sometimes with interest. 
  • Whether this is allowed depends on the lease terms, particularly if “time is not of the essence”. 
  • This guide explains backdated rent reviews for business owners and commercial tenants in the UK, prepared by LegalVision, a commercial law firm that specialises in advising clients on commercial leases.
  • It provides a practical explanation of rent review clauses, financial risks and how delays can impact your lease obligations.

Tips for Businesses

Check your lease for rent review clauses and timing rules. Budget for potential backdated increases, even if no review occurs on time. Consider negotiating rights to trigger reviews yourself to avoid large lump sum payments, and seek legal advice before agreeing to lease terms.

A backdated rent review occurs when a landlord assesses rent after the scheduled review date but applies any increase retrospectively from that original date. For your business, this can create significant financial risk, as you may face a large lump-sum “balancing payment” plus interest for past underpaid rent, even if the delay was not your fault. The lease terms will determine whether this is allowed, making it critical to understand your exposure and timing obligations. This article explains how backdated rent reviews work, when they apply and the risks for commercial tenants.

What is a Rent Review?

A rent review clause grants a commercial landlord the right to review the rental amount their tenant pays for the sole occupation of their commercial property. The commercial lease agreement will detail information about the rent review in the rent review clause. This will include when the rent review may occur, as well as the rent review method. 

Rent review methods include:

  • open market rent review, which is where the landlord assesses the rent in terms of the market value of the property if it were let to a new tenant at that time;
  • index-linked rent review, which is where a landlord assesses rent in accordance with an index such as the Retail Price Index (‘RPI’); and
  • stepped rent review, which is where the rent increases by a specific amount at a precise point in time-based on the parties’ agreement.

Generally, a rent review should not occur when the lease is of a seven-year term or less.

What is Backdated Rent?  

A rent review clause should always state when the review will occur. While the commercial lease agreement may expressly detail the exact rent review date, this may not necessarily be the date the rent review happens in practice. Instead, it is usually the date on which the rent review can commence. 

In this sense, a commercial landlord has some flexibility in carrying out the rent review. For example, they may be busy on the review date with another commercial property or could be away on holiday. Additionally, a rent review will take some time to complete and can result in the tenant appealing the rent increase. Therefore, the landlord generally has ample time to complete the rent review.

As a rent review can occur after the date when it may commence, the rent will remain at the current rental amount for the commercial tenant. When the rent review occurs later, the rental may stay the same or increase. If the rent increases, a commercial landlord has the right to backdate the difference of the increase from the rent review date specified in the lease agreement. They can also charge interest. Consider the following example. 

Suppose the commercial lease rent is £18,000 per annum. The rent review clause says that the rent review can commence from 1st April 2022, but the landlord does not conduct the rent review until 1st April 2023. The rent review on 1 April 2023 resulted in a rental increase to £20,000 per annum. Therefore, the commercial tenant will have to pay £2,000 to make up the rent difference for the year as they will have paid £18,000 as this was the previous rental amount.

How Does Backdated Rent Affect Commercial Tenants?

If a commercial tenant receives a request for backdated rent on their lease due to a review clause, the above scenario shows this can be a considerable amount of money they owe. Therefore, it is essential for a tenant’s perspective that they avoid falling into this situation. 

In this respect, it is beneficial for a tenant to negotiate that the rent review clause includes the ability for them to initiate a rent review when it is due. Although they do not want their rent to increase, as it ultimately may do, the review should happen sooner to avoid a hefty rent bill and interest. 

 Key Takeaways

A rent review clause in a commercial lease allows the landlord to review the amount of rent a tenant pays for their business premises. In practice, a commercial landlord may not actually conduct the rent review on the date the clause specifies. Instead, the landlord may review the rent after the date. In this instance, the lease usually allows the landlord to backdate any rent increase resulting from the rent review to this date. This means that a commercial tenant will have to pay the difference in the rental amount, plus interest, which could mean they face a hefty bill. Therefore, it is in the tenant’s interest to include a right to appeal a rent review.
