When to start renegotiating your lease - how many months before expiry?

Filip Sarzyński Filip Sarzyński · Partner · 12 June 2026 · 6 min read
In brief

For offices of 500-5,000 m², lease renegotiation should start at least 12 months before the lease expires, and 18-24 months ahead for larger premises. That time goes on a financial and technical audit, market research and gathering alternative offers. With 6 months left, the landlord makes only token concessions; with 3 months left, the tenant accepts whatever terms are on the table.

If you are waiting for the landlord to make the first move, or assuming you “still have time”, you are probably already losing money. When should you renegotiate your office lease? There is only one answer: much earlier than you think.

1The golden rule: 12-24 months before the lease expires

For companies occupying 500-5,000 m² of office space, an effective renegotiation process should begin at least 12 months before the lease expires. For companies with larger premises or more complex requirements, 18 to 24 months is the bare minimum.

This is not a safety margin. It is the time that quite literally determines how much you will pay over the next 5 years.

The more time left on your lease, the stronger your position in a renegotiation. Below 6 months, your room for manoeuvre all but disappears.

2Why so early?

Because good renegotiation outcomes do not come from a single conversation with the landlord. They come from preparation, and preparation takes time:

  1. 01

    Financial audit

    Checking whether your base rent is higher than the rent offered to new tenants in the same building. This happens more often than you might think.

  2. 02

    Technical and operational audit

    Gathering hard evidence on the condition of the building and any errors in how service charges are calculated.

  3. 03

    Market research and alternative offers

    Without a shortlist of competing locations, you have no real negotiating position.

  4. 04

    Time to negotiate

    Landlords do not work to a 24-hour turnaround, and every round of talks takes time.

Start too late and you negotiate under pressure.

And landlords can sense it immediately.

3What do you lose by starting too late?

Here are the concrete scenarios, depending on how much time is left on your lease:

3 months

Backed into a corner

You have no time to gather alternative offers. The landlord knows that relocating is not a realistic option for you. You can accept whatever terms are offered, or risk operational chaos.

6 months

Token concessions

You can talk, but you will not be able to build competitive pressure. The market will not have time to produce credible alternatives. The landlord will make token concessions: a few months rent-free and a minimal rent adjustment.

12-18 months

Full control

You run the full process: audits, market analysis and parallel negotiations with several landlords. This is the scenario that delivers a real rent reduction, a fit-out budget and terms that protect your company for years to come.

4Check when your lease expires, right now

Many companies do not know the exact expiry date of their lease. Some are unaware that a lease can renew automatically on its existing terms if notice is not served in time.

Do it today

Before you check anything else, open your lease and find the expiry date and the notice deadline. If fewer than 18 months remain, do not wait a single day longer.

Summary

The earlier you start, the more you can secure. This is how the time left on your lease translates into your negotiating position:

Time to lease expiry What you can do Position
18-24 months Full process: audits, market, negotiations, optimal terms strong
12-18 months A good outcome is possible, but you need to move quickly good
6-12 months Limited room for manoeuvre, time pressure limited
under 6 months Weak negotiating position, risk of an unfavourable lease amendment weak
