A letter from the landlord, three months before the term is up, a 12% rent rise “in line with the market”. Most commercial tenants sign, pay, and then regret it. Yet negotiating a lease renewal is not a battle lost before it begins: it is one of the rare moments when the balance of power can swing in your favour. You just need to arrive prepared, with figures, a credible alternative and a method. Here is how a seasoned negotiator approaches this deadline, so as not to be dictated to, but to decide.
Understanding the real balance of power
A landlord dreads one thing above all others: a rental void. An empty unit means months without rent, repair works to bring it back into shape, marketing costs, and an uncertain new negotiation. Conversely, a reliable tenant who has been paying for years represents a security that few owners willingly throw away. Your first source of leverage, then, is not your budget: it is your proven reliability. Before any discussion, put a figure on what your departure would genuinely cost the landlord. That cost is your bargaining chip.
Preparing your BATNA before you walk into the room
The decisive question is not “how much am I willing to accept?” but “what will I do if we fail to reach an agreement?”. That is your fallback option (BATNA). In practical terms: identify two or three comparable units available nearby, obtain their terms, and estimate your true cost of moving. A tenant who knows their alternative negotiates standing tall; one who has none negotiates on their knees. Even if you would rather stay, this preparation changes everything: it comes through in your voice and in your ability to say no.
Anchoring the discussion on objective criteria
Faced with “the market has gone up”, never respond with a gut feeling. Respond with objective criteria: the statutory reference index (the ILC or ILAT index for a commercial lease), the rents actually charged in the same building, the condition of the unit, the works you funded yourself. By putting your own figures on the table first, you create an anchoring effect: the negotiation will unfold around YOUR reference point, not theirs. A claimant who talks numbers holds the conversation; one who merely reacts is held hostage by it.
The story of Camille, or how to reverse a 12% rise
Camille runs a physiotherapy practice that has occupied the same premises in Bordeaux for six years. Three months before the term ends, the landlord sends her a draft renewal: rent raised from 1,800 to 2,016 euros, “in line with the market”. Her first instinct is to give in; moving would be a nightmare with her local patient base.
She takes a fortnight. She spots two vacant units within 500 metres, one at 1,750 euros, the other at 1,900 but needing refurbishment. She gathers her evidence: not a single missed payment, 4,200 euros of accessibility works for people with reduced mobility paid out of her own pocket, a shopfront that adds value to the building. On the day of the meeting, she does not say “it’s too expensive”. She puts it this way: “I’d like to understand. Which index are these 12% based on? Because the ILAT over the period comes out closer to +3.5%.”
The landlord hesitates. Camille follows up with a calibrated question: “How am I supposed to justify such a rise to my accountant when the unit upstairs is being re-let for less?” Then she falls silent. That silence, a few seconds long, puts the pressure on the right side of the table. The landlord eventually moves: “Let’s say +5%.” Camille calmly rephrases, drawing on tactical empathy, “I understand you want to keep pace with the market, and I want to stay”, then proposes a give-and-take: rent at 1,850 euros in exchange for a firm three-year commitment and repainting the frontage at her own expense. Deal signed. She gains her stability; the landlord keeps a model tenant. The 12% rise has become +2.8%.
Locking it down without caving at the last minute
Landlords often test your resolve at the end of a negotiation. Two professional reflexes. First, if the gap persists and your alternative is solid, dare to use the walk-away: “On those terms, I’m going to have to look seriously at the other two units.” That is no bluff when your BATNA is real. Second, negotiate the package, not just the rent: term, rent-free period for works, allocation of service charges, a cap on indexation. A concession presented as a significant effort (a commitment on the term that suits you anyway) can unlock a genuine reduction on the amount. Repeat every agreed point out loud, then insist on written agreement before you commit.
- Anticipate: start six months before the term, never at the last minute.
- Quantify the cost of your departure to the landlord; that is your real power.
- Document comparable rents, statutory indices and works you have funded.
- Broaden the negotiation beyond the amount: term, charges, works.

FAQ
When should you start negotiating your lease renewal?
As early as possible, ideally six months before the term ends. That window gives you time to scout alternative premises, build up your file of comparables and construct a genuine BATNA. Negotiating in a rush, a few weeks out, amounts to negotiating without an alternative: the weakest position there is.
How should you respond to a rise “in line with the market”?
Never challenge it with a gut feeling. Calmly ask which precise index and which comparable rents the rise is based on, then counter with your own objective criteria (the actual ILC/ILAT figure, rents in the same building, works you have funded). By insisting that the figure be justified, you shift the burden of proof onto the landlord and bring the discussion back to verifiable ground.
