Our Expert Dilapidation Advice for Landlords and Tenants

If you manage commercial or mixed-use property, dilapidation is rarely a one-off issue. It surfaces at lease renewals, break clauses and, most commonly, at lease expiry, and it can catch out a landlord just as easily as a tenant. Getting good advice early, from a qualified dilapidation surveyor, is what separates a smooth handover from a costly dispute.

Below, we explain what dilapidation means, the role we play in a dilapidation claim, how to assess and manage the risk on both sides, and the practical next steps we recommend, whichever side of the lease you are on.

What Does Dilapidation Mean in a Commercial Lease?

Dilapidation refers to a breach of the repair, reinstatement or decoration obligations set out in a commercial lease. In practice, this covers everything from a tenant failing to keep the fabric of a building in good repair, to leaving alterations in place that should have been removed, to handing back a unit in a worse decorative state than the lease required.

Interim dilapidations are breaches identified during the lease term, often flagged during a periodic inspection or ahead of a rent review. Terminal dilapidations relate to the property's condition at lease end, and tend to carry the highest value and greatest risk of dispute, since there is no further opportunity for the tenant to remedy the works themselves.

For a mixed-use landlord managing several tenancies, or a commercial property manager overseeing a portfolio, knowing which obligations apply to which unit, and at what point in the lease cycle, is the foundation of managing dilapidation risk sensibly. A dilapidation survey at the right time gives you an accurate, evidence-based picture of a property's condition relative to its lease obligations, rather than a guess.

In short, dilapidation is a lease-driven repair obligation, and knowing whether you are looking at an interim or terminal position changes how the matter should be handled.

What Is the Dilapidations Protocol, and Why Does It Matter?

The dilapidations protocol, formally the Pre-Action Protocol for Claims for Damages in Relation to the Physical State of Commercial Property at Termination of a Tenancy, sets out how landlords and tenants should behave before a terminal dilapidations dispute reaches court. It requires the landlord to serve a schedule of dilapidations and quantified demand, generally within 56 days of the lease ending, and gives the tenant a similar window to respond formally to each item.

The protocol exists to encourage early, full disclosure and give both sides a fair chance to settle before legal costs escalate. Courts take a dim view of parties who ignore it, and non-compliance can affect costs even where the underlying claim has merit. We cover the mechanics of the protocol, including the Section 18 diminution cap and supersession, in more detail in our dedicated article on the dilapidations protocol, worth reading alongside this piece if you are approaching a terminal claim.

In short: the dilapidations protocol is a structured, time-limited process, and following it properly protects your position whichever side of the claim you are on.

What Role Does a Dilapidation Surveyor Play in a Claim?

A dilapidation surveyor's job is to bring independence, accuracy and RICS-compliant rigour to a process that can otherwise become adversarial very quickly.

Acting for a landlord, we prepare or review the schedule of dilapidations and quantified demand, ensuring every item is properly evidenced, correctly categorised and realistically costed, rather than inflated. Acting for a tenant, we assess the landlord's schedule item by item, challenge anything unreasonable, superseded or simply not the tenant's responsibility, and prepare a formal response that protects your position under the protocol.

In both cases, the value of instructing a qualified dilapidation surveyor lies in impartiality. We are bound by RICS professional standards, so our advice reflects what the evidence supports, not what either party would prefer to hear. This matters particularly where a diminution valuation is needed to establish the true financial loss, rather than simply the cost of remedial works. Our full building and structural survey experience means we can identify genuine structural or fabric issues quickly, separating them from cosmetic wear that falls outside the lease terms.

In short, a dilapidation surveyor's role is to produce accurate, defensible evidence, whichever side of the negotiation you are sitting on.

How Can Landlords and Property Managers Assess and Manage Dilapidation Risk?

For commercial property managers and mixed-use landlords, dilapidation risk is best managed proactively rather than at the point a lease ends. A schedule of condition prepared at the start of a tenancy, regular interim inspections and clear lease drafting around reinstatement obligations all reduce the likelihood of a disputed claim later on.
