Tips for Businesses

Check your lease carefully before initiating a rent review – it governs every step of the process. Serve notices within the required timeframes, keep records of all correspondence, and always sign a rent review memorandum, even where rent remains unchanged. If agreement cannot be reached, instruct a professional surveyor promptly.

As a commercial landlord, reviewing the rent you charge your tenants is an important part of managing your property, but the process must be followed correctly to be enforceable. Understanding each step of a rent review helps you avoid disputes and ensures your lease remains commercially viable. This article will explain what the standard rent review process is.

Rent Review   

A rent review is when you, as a commercial landlord, have the ability to adjust the rent you charge your commercial tenants.  This generally means putting the rent up, which is the market standard position in the UK. 

Your lease agreement should contain a rent review clause detailing when to carry the review out. Typically, you will conduct a rent review every three to five years of the tenancy. This is often agreed with the tenant with all other commercial terms, ahead of the lease being drafted.

Leases must specify the type of rent review. Some common rent review mechanisms are:

  • an inflation-linked review  based on the Retail Price Index or Consumer Prices Index;
  • a fixed (pre-determined) increase;
  • an assessment based on your tenant’s turnover; or
  • an open-market assessment.

What Does the Process Include?

The commercial rent review process depends partly on what type of assessment you use as a landlord. We explain the typical steps of the rent review procedure below.

1. Rent Review Assessment

As part of the rent review process, you must assess the new rent amount. The assessment will depend on which type of rent review mechanism is included in the lease. For example, if you carry out an open-market evaluation, the new rent will be based on a hypothetical lease, similar to the one in place with your tenant. You will assess the market value of that lease, focusing on:

  • the area your commercial property is in;
  • the condition of the premises; and
  • the terms of the commercial lease

The lease will often specify things to be disregarded, such as the nature of the tenant’s business or improvements they’ve made to the property.

2. Serve Notice

Once you have made the rent review assessment and decided that your commercial tenant’s rent amount will increase, you should notify them. Your lease agreement will contain the details of your notice requirements for a rent review.

Your tenant may wish to challenge the market assessment under the rules in the lease. This may involve them serving you with a counter notice letter, typically within 28 days after they receive your notice.

3. Serve Notice

If your commercial tenant serves a counter notice, you must allow time to agree to the new rent amount. Your lease agreement will usually specify a period prior to the rent review date during which the rent should be agreed.

If you cannot agree on a new rent amount, the lease will detail the next step in the process. Usually, this will be to appoint an independent expert who is a professional surveyor to decide on what the rent amount should be due to your rent review.

4. Documentation

When you carry out the rent review process, it is in your interest to ensure you document where appropriate. This should include:

  • the dates of the rent review;
  • the new rent level agreed upon; and
  • when the new rent will apply.

It is preferable to enter into a short rent review memorandum to record these points and for you and your commercial tenants to sign it. Your commercial property solicitors should assist with this. You should do this even if a rent increase does not arise after the rent review. This is because it records that the rent review process took place.

Key Takeaways

As a commercial landlord, you may conduct a commercial rent review for your commercial tenants’ property. This allows you to assess if the level of rent they pay is correct. However, your lease should detail the rent review process which you must follow. Some steps may include:

  • notifying your tenants that you will carry out a rent review;
  • documenting the rent review process; and 
  • including a rent review memorandum which you will both sign. 

If you do not agree to rent after giving your tenants notice of any rise, you may need to involve a surveyor.
