Facing a rent increase you can't justify, or a rent that's fallen behind the market? Either way, the gap adds up: over a five-year lease it can run to six figures. Here are four recent cases, with the rent before and after we stepped in.

How a rent review or lease renewal works

Three steps, and the first one costs nothing.

  1. Free lease analysis

    We'll analyse your lease without charge and in confidence, and explain our fee options: fixed, performance-based, or both.

  2. We negotiate on the evidence

    We build your case from comparable rents, drawing on our own property database, and negotiate with the other side.

  3. Agreement or arbitration

    Most cases are settled by negotiation. If not, your lease may provide for arbitration or expert determination, and we'll represent you.

Talk to us early. Some leases set strict time limits for rent review notices, and missing one can be costly. Read: Time can be of the essence Not due yet? Check how ready you are.

Rent review and lease renewal questions

The questions landlords and tenants ask us most.

What is a commercial rent review, and how does it work?

Most commercial leases let the rent be reviewed at set dates, usually every three, four or five years. At the review the landlord can propose a new rent, which the lease normally says should reflect the open market rental value. If the evidence doesn't support an increase, the tenant can oppose it.

What is a rent review clause?

It is the part of a commercial lease that says how the rent can be reviewed: the review dates, usually every three, four or five years; what the new rent is based on, normally the open market rental value unless the rise is fixed or linked to RPI; any time limits for notices and counter-notices; and who decides if the two sides can't agree, usually an arbitrator or independent expert appointed by the RICS.

Check yours: take the rent review readiness check
How is the new rent worked out?

Usually on open market rental value: the rent the property would achieve if let today to a new tenant, compared with similar premises in a similar location and on similar lease terms. Recent lettings nearby are the strongest evidence, and rents are compared per square foot, not by the headline figure.

Read: Open market rent, what does it mean?
My landlord has proposed a big increase. Do I have to accept it?

No. A landlord can quote any rent they wish, but unless it's justified by the evidence, a surveyor can show why it's wrong. Act quickly, though: some leases set strict time limits for objecting, and if a counter-notice isn't served correctly, the proposed rent can become final.

Read: Time can be of the essence
Can the rent go down?

At a rent review, usually not. Most reviews are upward only, so the aim is to keep the rent where it is or keep any increase to a minimum. At a lease renewal it's different: in certain circumstances, a new rent lower than the old one can be negotiated.

Can a rent review be backdated?

Often, yes. Most leases let the landlord serve a rent review notice at any point after the review date, even years later, and the new rent is then backdated to the review date. That can leave a tenant with a large, unbudgeted bill for back rent, so it pays to deal with the review on time.

Read: Avoiding back rent
What happens when my commercial lease ends?

The tenant can leave, or begin the process of renewing the lease. A crucial question is whether the lease is protected by the Landlord and Tenant Act 1954, which gives the tenant a legal right to renew and strengthens their negotiating position. A detailed knowledge of current market rents is essential when agreeing the new terms.

Read: Commercial lease renewals
What is a Section 25 or Section 26 notice?

They are the formal notices that start a lease renewal under the 1954 Act: a Section 25 notice is served by the landlord, and a Section 26 notice by the tenant. Legal advice is needed to serve one, and the dates they set matter.

Read: Section 25 and 26 notices explained
What if we can't agree on the rent?

Most rent reviews and lease renewals are agreed by negotiation. If talks fail, most commercial leases provide for arbitration or expert determination: either side can ask the RICS to appoint an arbitrator or independent expert, both put their case in writing, and the decision is final.

How much does a rent review surveyor cost?

With us, it starts with a free lease analysis, without obligation. After that, fees can be fixed, performance-based or a mix of the two, depending on your situation.
