Break dates in commercial leases

In an interesting recent case, Sterling House Ltd v International Baccalaureate Organisation (UK) Ltd [2026] EWHC 2680 (BP), a landlord claimed that its tenants' break notice was ineffective because the required annual rent and insurance rent had not been paid by the break date, as required by the break conditions set out in the tenants’ lease. The High Court dismissed the landlords' claim.

This case highlights the importance of the terms of the lease, the communications between parties and, furthermore, the practicality of conditions that may be imposed by a break clause. 

In this case, the tenant’s facilities manager requested by email (and subsequently chased) the rent invoice from the landlord agents, explaining that they needed to pay before handing back the building. The tenant’s facilities manager did not specifically request the insurance rent demand, but the courts held that the context of the emails made it clear that the tenant needed to know the amount required for the handover to take effect (which would include the insurance rent in accordance with the break clause conditions).

The agent responded with reference to the lease terms but only invoiced the annual rent to the break date (despite this leaving monies still owing under the terms of the break clause) and did not send any demand for the insurance rent. The court held that the invoice supplied by the agent represented what the landlord required to be paid before handover, and that the Tenant reasonably relied upon the invoice being correct given the initial request, subsequent chaser and the clarity of the invoice about the sums due at the break date. 

It is therefore an important point for Landlords to ensure any rent demands are served in the usual way irrespective of any break date set out in the lease (i.e. to demand the usual full instalment – even where this means collecting rent for a period beyond a break date) because under the terms of most commercial leases, a break clause will require the tenant to have paid all the annual rent due (which can take the tenant past the break date in terms of the period they are paying for) and not just an apportioned amount taking it to the break date. The tenant’s interests are usually protected here as the terms of the break clause usually require the landlord to refund (after the valid operation of the break clause) any proportion of rent paid that relates to the period beyond the break date.

Another condition of the break clause in this case was that the tenant must have paid the insurance rent due by the break date, and the insurance rent was a figure payable on demand. The court held that the tenant did not have a reasonable opportunity to pay this because it was demanded shortly before the break date. This highlights the importance of considering the practicalities of conditions imposed by break clauses and whether parties can reasonably comply with them and that where sums are payable ‘on demand’, the Landlord will still need to ensure sufficient time is given to allow the Tenant to comply with that demand if it requires satisfaction of it by a break date. 

Care must therefore be taken not only by your legal representative when drafting break clauses, but also between parties themselves as this case clearly demonstrates the impact communications can have when seeking to enforce lease terms.

For the avoidance of doubt, please contact your legal advisors before seeking to enforce your rights under your lease, as they will be best placed to ensure valid notices are served to avoid litigation taking place, as demonstrated in this case.
