Understanding Commercial Dilapidations Protocol in the UK
Watts Group Limited
Commercial dilapidations claims follow a structured legal process that most landlords and tenants underestimate. Before any court action can begin, both parties must follow a defined sequence of steps. That sequence is the Pre-Action Protocol for Claims for Damages in Relation to the Physical State of Commercial Property at Termination of a Tenancy.
Get any stage wrong, or skip it, and the courts can impose cost penalties, pause the claim, or both. Read on to learn everything you need to know about commercial dilapidations protocol in the UK.
What commercial dilapidations means
Commercial dilapidations refer to breaches of the repair, decoration and reinstatement obligations set out in a commercial lease. At lease expiry, a landlord can claim damages from a tenant who has left the property in a condition that falls short of those obligations. Claims are based on the obligations set out in the lease, rather than a landlord’s preferred standard, subject to statutory limitations such as Section 18(1).
This is a well-established area of property law, but the process is more structured than many landlords and tenants realise. Both parties must follow a defined sequence of steps before any court action can be taken. That sequence, referred to throughout this article as the Dilapidations Protocol, came into force in 2012 as part of the Civil Procedure Rules 1998 and primarily applies at lease termination.
What happens if commercial property dilapidations protocol is ignored
The Protocol exists to reduce the number of commercial lease dilapidations disputes that reach court. It does this by encouraging early disclosure of information between parties, and by creating a structured basis for negotiation.
It is not a procedural formality. Courts can impose cost penalties on a party that has not followed the required steps. In some cases, a claim may be paused while compliance is achieved. Given that commercial property dilapidations claims can run to hundreds of thousands of pounds on larger properties, the cost of getting the process wrong at any stage can be high.
Step 1: the schedule of dilapidations
The landlord's first obligation under the Protocol is to prepare and serve a Schedule of Dilapidations. This document sets out each alleged breach of the lease: the clause breached, the nature of the disrepair or failure, and the works the landlord says are required.
It must be served within a reasonable time after lease expiry. There is no fixed deadline, but in practice schedules are often served within around 56 days. Complex properties like large multi-tenanted buildings or those requiring specialist investigation may justify a longer period. But courts may take a critical view with schedules served long after the lease has ended without good reason.
Terminal and interim schedules
A terminal schedule covers the position at lease expiry and forms the basis of a damages claim. An interim schedule is served during the lease term. This usually happens where a landlord believes disrepair is occurring that could worsen or affect the property's value. Interim schedules are less common in many commercial contexts, but they carry their own obligations and risks. A landlord who serves one prematurely or disproportionately may face pushback from the tenant and complications later in the terminal process.
The commercial dilapidation survey behind the schedule needs to be thorough and property-specific. Vague or inflated items weaken the landlord's position from the beginning and could lead to challenges at every stage that follows.
Step 2: serving the quantified demand
Served either with the Schedule or shortly afterwards, the landlord must serve a Quantified Demand. This document sets out the financial claim: the cost of each item of repair or reinstatement, plus any other losses. These could be loss of rent during a remediation period, professional fees and VAT where applicable.
Each item should be fully costed, with the basis of the figures disclosed. Landlords are expected to put forward a realistic and evidenced claim. That means not padding the schedule with works the landlord never intends to carry out or claiming reinstatement costs for alterations that added value to the property.
A commercial property dilapidations assessment carried out by a surveyor who understands the Protocol will stand up to scrutiny. An overstated claim puts the landlord at risk of cost sanctions and weakens credibility in later negotiations. And an under-prepared claim may leave recoverable losses on the table.
Step 3: the tenant's response
Once the Schedule and Quantified Demand have been served, the tenant has a defined period to respond. Again, this is typically 56 days. The response must address each item, either accepting, partially accepting or disputing it. Where items are disputed, the tenant must give reasons.
The Scott Schedule
After the tenant's response, the Protocol requires the parties to engage in genuine without-prejudice negotiations. The aim is to narrow the gap between their positions and, where possible, reach agreement without court proceedings.
The without-prejudice period lasts a minimum of 28 days. Commercial property dilapidations negotiations often take considerably longer, particularly on larger assets where multiple items are in dispute or where the parties' valuations differ widely. Neither side is required to settle, but both are expected to engage constructively. Courts take a dim view of parties who refuse to negotiate or who use the Protocol steps as a stalling tactic.
How the Section 18(1) cap limits the landlord's claim
One of the most significant constraints on commercial dilapidations claims is the cap set by Section 18(1) of the Landlord and Tenant Act 1927. It limits the landlord's recoverable damages to the diminution in the value of the reversion. In simpler terms, the reduction in the property's capital value caused by the tenant's breach.
Where the cost of the works exceeds that diminution, the landlord's damages are capped at the lower figure. And where the landlord intends to redevelop or demolish the property at or shortly after lease expiry, the Section 18(1) cap may reduce the claim to nil, because no diminution in value has occurred.
Tenants with experienced advisers will almost always commission a Section 18(1) valuation as part of their response. Landlords should expect this and make sure their own commercial property dilapidations assessment accounts for it. Ignoring the cap, or hoping the tenant won't raise it, rarely ends well.
When the protocol breaks down
The Protocol is designed to resolve or narrow disputes before court. Most commercial dilapidations disputes are settled at some point during the process, either at negotiation, or shortly before a hearing.
When negotiations fail, the landlord may issue proceedings. At that point, the court will examine how both parties behaved during the Protocol process. Unreasonable refusals to engage, inflated schedules without evidence, and procedural shortcuts all carry cost risk.
