What Is a Dilapidation Survey?
Watts Group Limited
A dilapidation survey, also referred to as a dilapidation inspection, is a formal inspection of a commercial property that records its physical condition at a specific point in time. It is most commonly undertaken in the final years of a lease, although you can also have surveys carried out at the start of a tenancy, or partway through it.
The survey produces a documented record of what state the property is in, where that condition has deteriorated and where a tenant may have failed to meet their obligations under the lease. That record becomes the basis of any dilapidations claim.
Read on to learn more about dilapidation surveys and what they involve.
What are dilapidations?
The term ‘dilapidations’ means repairs required either during or at the end of a tenancy. The term is commonly used to refer to damage or disrepair to parts of the property that the tenant was required to maintain under the terms of their lease. However, dilapidations may also include failure to redecorate (if required by the lease) or unauthorised alterations to the property that have not been reinstated.
A dilapidation survey is the process of identifying and evidencing those breaches in a form that can be acted on. For landlords, the survey provides the evidence needed to support a schedule of dilapidations. For tenants, commissioning an early survey identifies liabilities before they grow. Getting ahead of the process is nearly always less costly than responding to it.
What does a dilapidation survey cover?
The scope of a commercial dilapidation survey depends on the property type, the lease terms and the stage at which the survey is carried out. That said, most inspections follow a broadly consistent structure.
The surveyor will typically assess:
- The structural fabric of the building, including walls, roof, floors and external elements
- Internal condition—ceilings, partitions, fixtures, finishes and flooring
- The structural fabric of the building, including walls, roof, floors and external elements
- Alterations carried out during the tenancy that may require reinstatement at lease expiry
- Decorative condition, both internal and external, including any specific redecoration obligations set out in the lease
Each finding is assessed against the tenant's lease covenants. These are the repairing, decorating and yielding-up obligations that the lease itself specifies. A dilapidation survey does not apply a universal standard. It applies the standard the particular lease requires.
This is a distinction worth understanding. A property in generally poor condition may still generate a substantial dilapidations claim if the tenant's repairing obligations were broad and those obligations were not met. Equally, a tenant who has looked after the property carefully may still face reinstatement costs if alterations were made without the landlord's consent.
When do you need a dilapidation survey?
The most common trigger is an approaching lease expiry. A landlord's surveyor will usually carry out a terminal dilapidations survey in the final months of the term to identify breaches before the tenant vacates. Tenants in the final year of a lease should expect one.
However, a dilapidation inspection is not only a tool for lease end. Tenants may benefit from instructing their own surveyor to carry out an interim dilapidation survey during the lease term. This gives an honest picture of accruing liabilities while there is still time to act. This could mean carrying out repair works, making good alterations or building an accurate financial provision. Waiting until the final year typically leaves fewer options and less room to negotiate.
At the start of a tenancy, a schedule of condition is sometimes agreed and attached to the lease. This records the property's state before the tenant takes occupation. It sets the baseline against which the tenant will be assessed at lease expiry. It can substantially limit the tenant's exposure where a property was already showing signs of wear when the tenancy began.
When should a schedule of dilapidations be served?
The terminal schedule is typically served within the final 12–18 months of the lease (and legally within the last three years, depending on the lease), or after the tenant has vacated. Interim schedules, served mid-lease to encourage the tenant to carry out required repairs, may be permitted under the lease, though they are used less often.
Tenants who receive an interim schedule should respond quickly. Failing to act on it can strengthen a landlord's position considerably at the end of the term.
Tenants can also instruct their own surveyor independently. Not only to understand accruing liability mid-lease, but to review a schedule served by the landlord. Having their own surveyor's assessment gives tenants a grounded basis for negotiation rather than accepting the landlord's figures without scrutiny.
How is a dilapidation survey carried out?
A dilapidation survey has two main stages: a physical inspection of the property, and the preparation of a written schedule setting out every breach identified and what remedy is required.
The initial inspection
The purpose of the dilapidation inspection is to record the property's condition against the tenant's lease obligations. The surveyor works through the building in a structured order, starting with external elements: the roof, facade, external drainage, boundary walls and any yard or parking areas, before moving through the internal spaces.
The inspection is thorough. A surveyor will open access hatches, examine roof voids and service areas, look behind removable fixtures where access permits and record every item that falls short of the required standard. Photographs are taken throughout to support the written notes in the schedule.
The lease runs alongside the inspection. Each defect is tested against the specific obligation in the lease—whether that's repairing, decorating, reinstating or meeting statutory requirements—to confirm whether a breach actually exists. Items that fall outside the tenant's obligations are noted but excluded. The schedule needs to be proportionate and defensible.
Access needs to be arranged in advance. If it is a landlord-instructed survey, reasonable notice must be given to the tenant. For larger or more complex buildings, the initial inspection can be spread out over more than one visit.
The dilapidation survey report
Once the inspection is complete, the findings are compiled into a dilapidation survey report—formally called a schedule of dilapidations—which lists each breach identified, the specific lease obligation that hasn't been met and what remedy is required.
Where a cost is attached to each item, this is usually an estimated repair cost. The total damages a landlord can recover may be subject to a statutory cap under Section 18(1) of the Landlord and Tenant Act 1927. The damages cannot exceed the reduction in the market value of the landlord's interest caused by the breach, and no damages are recoverable if the landlord intends to demolish or substantially alter the property after the lease ends
The length and detail of a dilapidation survey report will vary with the property and the purpose. A terminal schedule served on a tenant approaching lease expiry will typically be more comprehensive than an interim schedule served mid-term. For larger commercial properties, a detailed schedule may run to many pages and cover dozens of individual items across multiple categories.
A well-prepared schedule is a document built to withstand scrutiny, whether from the tenant's surveyor, from a mediator or, if matters proceed that far, from the courts. The professional standard for preparing and responding to schedules is set out in the RICS Dilapidations guidance note (7th edition)
If tenants disagree
Where a tenant disagrees with the items in a schedule, or the costs attributed to them, their surveyor will prepare a response. This is often presented as a Scott Schedule, and it sets out, item by item, which findings are accepted and which are disputed. It is the standard working document for surveyor-to-surveyor negotiation and, if a claim proceeds to tribunal or court, the format in which disputed items are presented.
The large majority of commercial dilapidations claims are resolved at the negotiation stage without reaching litigation.
Who can carry out a commercial dilapidation survey?
A dilapidation survey for a commercial property should be carried out by a qualified building surveyor. This is typically a chartered surveyor registered with the Royal Institution of Chartered Surveyors (RICS). The RICS Dilapidations guidance note, which sets the professional standard for this work, applies to its members. Where disputes escalate, courts expect surveyors on both sides to have followed it.
Typically, both landlords and tenants will instruct their own surveyor. The landlord's surveyor prepares the schedule and quantifies the claim. The tenant's surveyor reviews it, challenges items where appropriate and negotiates the final settlement.
A landlord's surveyor and a tenant's surveyor can legitimately reach different conclusions. The wording of the lease, the condition of the property, the evidence gathered during inspection and the applicable statutory limits all require judgement.
Watts' building surveying team advises landlords and tenants on dilapidations throughout the lease term and at expiry. Our approach follows the RICS Dilapidations guidance note and is proportionate to the specific circumstances of each case. Whether you are preparing or responding to a schedule, you need a surveyor who knows both sides of the process.
What equipment is used in a dilapidation survey?
A commercial dilapidation survey requires the surveyor to attend the property in person, and to use a range of tools to record condition accurately and produce findings that will hold up to scrutiny.
Standard equipment includes:
- A camera or high-resolution phone for systematic photographic recording; photographs support every item listed in the schedule.
- A damp meter to identify moisture in walls, floors and ceilings where surface condition alone may not be conclusivA torch for inspecting poorly lit areas: roof voids, plant rooms, service ducts and basement spaces
- A laser measure for recording dimensions, particularly where reinstatement of tenant alterations is in question
- A ladder, or access equipment, for examining high-level elements, such as gutters, fascias and roof-level plant that cannot be assessed from ground level
For more complex properties or where specific concerns have been flagged, a surveyor may also use a thermal imaging camera to identify hidden moisture or insulation failure, or in more specialist circumstances a crack monitor to assess the progression of structural movement over time.
A surveyor will confirm what access and equipment will be required before the inspection takes place, so arrangements can be made in advance.
How much does a dilapidation survey cost?
Dilapidation survey costs vary. There is no fixed fee across the industry, and any figure given without reference to the specific property and instruction should be treated with caution.
The main factors that affect cost are the size and complexity of the building, the scope of the surveyor's instruction, the stage of the lease at which the survey is carried out and whether the instruction includes a fully quantified schedule or an initial inspection only. For example, a dilapidation survey and schedule will generally cost less for a single-floor commercial unit than for a multi-storey office building with complex mechanical and electrical systems.
It is also worth separating the survey cost from the potential financial exposure it helps manage. A dilapidation liability on a commercial property can run to tens of thousands of pounds, and considerably more on larger leases.
A surveyor's fee, set against that exposure, should be viewed as proportionate professional advice rather than an overhead. Tenants who put off getting advice until a schedule lands on their desk tend to have less room to challenge it and less time to carry out remedial works that could reduce the claim
