What Is the Dilapidations Protocol and Why Does It Matter?

24 June 2026

When a commercial lease comes to an end, disputes over the condition of a property are remarkably common. The dilapidations protocol exists to bring structure and fairness to this process, setting out how landlords and tenants should communicate, exchange information, and attempt to resolve claims before matters escalate to litigation. Understanding how it works and why expert surveying advice is so important can make a significant difference to the outcome of any dilapidations dispute.

What Is the Dilapidations Protocol?

The Pre-Action Protocol for Claims for Damages in Relation to the Physical State of Commercial Property at Termination of a Tenancy, more commonly known as the dilapidations protocol, forms part of the Civil Procedure Rules in England and Wales. Its purpose is to encourage both parties to engage constructively and transparently before any court proceedings are considered. Rather than allowing disputes to escalate unnecessarily, the protocol promotes the early exchange of schedules, costings, and responses, helping landlords and tenants understand each other's positions and, where possible, reach a negotiated settlement.

How the Process Works

Under the dilapidations protocol, a landlord is expected to serve a schedule of dilapidations, typically a detailed document outlining the alleged breaches of the lease, the required remedial works, and the associated costs within a reasonable period of the lease ending. In most cases, this should be served within 56 days of the lease termination.

Once the schedule has been served, the tenant has the opportunity to respond formally. The protocol requires the tenant's response to address each item in the schedule, either accepting the claim, disputing it, or providing their own costings where they disagree with the landlord's figures. This structured approach ensures that both parties are properly informed before any legal action is pursued.

Why Professional Surveying Advice Matters

The dilapidations protocol places considerable emphasis on the quality and accuracy of the documentation exchanged between parties. A poorly prepared schedule, or a response that fails to address the relevant issues properly, can significantly weaken a party's position, whether that is a landlord seeking to recover costs or a tenant looking to minimise their liability.

This is where our expertise as chartered building surveyors becomes invaluable. We regularly advise both landlords and tenants at all stages of the dilapidations process. We can prepare or review schedules of dilapidations, assess the reasonableness of claimed remedial works, and provide clear, impartial advice on the likely level of any award should the matter proceed to dispute.

Supersession and the Diminution Cap

One important aspect of dilapidation claims that is frequently misunderstood concerns the concept of supersession and the diminution cap. Even where a landlord has a valid claim for disrepair, the damages recoverable are limited to the reduction in the value of the landlord's interest caused by the breach, not simply the cost of the works. Where a landlord intends to redevelop or refurbish the property regardless of its condition, the costs of remedial works may be superseded entirely.

Navigating these nuances requires specialist knowledge, and professional guidance at an early stage can prevent costly errors on both sides.
