Lease Interim & Terminal Dilapidations Advice in Harrow, Serving London & the South East
Commercial lease obligations can create significant financial exposure when repair, reinstatement and decoration liabilities are not identified early.
Having advised landlords, tenants and commercial property owners for more than 35 years, our Chartered Dilapidations Surveyors provide Lease Interim & Terminal Dilapidations Advice in Harrow, while supporting clients across London and the wider South East. We assess lease obligations, property condition and likely costs to establish a clear, commercially informed position.
What Are Interim & Terminal Dilapidations?
Dilapidations are breaches of lease obligations relating to repair, decoration, reinstatement or the condition in which commercial premises must be maintained and returned.
The timing of the assessment determines how the advice is used:
- Interim Dilapidations: Address breaches during the lease term, allowing deterioration to be identified and appropriate action considered before expiry. An Interim Schedule of Dilapidations would not typically include costs, although a cost assessment can be provided where specifically requested by the client.
- Terminal Dilapidations: Assess breaches at or approaching lease termination, when repair obligations, reinstatement requirements and the landlord’s resulting loss must be established.
We act for both landlords and tenants, interpreting the relevant lease obligations and translating building condition into practical advice on liability, remedial works and negotiation.

Our landlord-focused Dilapidations Guide explains the importance of planning before lease end, the building elements commonly assessed and the structured process used to identify, schedule, value and negotiate breaches.
Dilapidations Advice for Landlords
For landlords, commercial property dilapidations are primarily about protecting the condition and value of the asset while establishing whether the tenant has complied with its lease obligations.
Our advice can help landlords:
- Identify breaches during or approaching lease expiry
- Assess repair and yielding-up obligations
- Prepare an Interim or Terminal Schedule of Dilapidations
- Identify reinstatement requirements
- Assess remedial costs where appropriate, noting that Interim Schedules would not typically include costs unless specifically requested
- Support negotiation and, where appropriate, a quantified demand
- Plan ahead for refurbishment or reletting
Early advice can provide more time to establish a clear position and reduce uncertainty before the lease ends.
Dilapidations Advice for Tenants
For tenants, early advice can help identify and manage potential liability before lease expiry or following receipt of a landlord's claim.
We can help tenants:
- Understand repairing and yielding-up obligations
- Review a landlord's Schedule of Dilapidations
- Assess whether individual items are justified
- Challenge unreasonable or disproportionate works
- Consider whether works may be superseded by future redevelopment
- Budget for repairs and reinstatement of alterations
- Negotiate an appropriate commercial settlement
Understanding potential liability early may also allow tenants to complete appropriate works before lease expiry where this is commercially beneficial.
Schedule of Dilapidations
A Schedule of Dilapidations sets out alleged breaches of lease obligations and the works or remedies considered necessary.
For landlords, we can prepare a detailed schedule identifying the relevant breaches and appropriate remedies.
For tenants, we review the claim against the lease obligations, building condition and appropriate repair standard, helping establish whether individual items and associated costs are justified.
Where condition was formally recorded at lease commencement, a Schedule of Condition [LINK TO NEW PAGE] can also provide important evidence when determining responsibility for subsequent deterioration.
What We Assess & Why It Matters
A Dilapidations Survey requires more than recording visible defects. The condition of the property must be considered against the obligations contained within the lease and the commercial circumstances at the time.
Depending on the property and instruction, we assess:
Common Dilapidations Risks We Identify
Unresolved lease obligations can affect both asset value and the financial outcome at lease termination.
Common matters include:
Lease Obligations & Dilapidations Claims
Dilapidations claims must be considered against the lease and the circumstances at the time.
Relevant matters can include:
- Repair and yielding-up obligations
- Reinstatement of tenant alterations
- Supersession, where proposed future works may affect the need for claimed repairs
- The Dilapidations Protocol
- Statutory limitations, including Section 18 of the Landlord and Tenant Act 1927
Repair and reinstatement costs are assessed using KEYS Consulting’s own benchmark rates, developed from more than 30 years of property and construction experience. These rates are reviewed annually against current market information and our experience of live and completed projects, providing a practical basis for assessing the likely cost of remedial works.
Our role is to provide technical and commercial surveying advice. Where legal interpretation of the lease or contractual obligations is required, clients should refer the matter to their solicitor.

Our Dilapidations Process
Our approach follows a structured sequence designed to establish liability, quantify the claim and support a commercially appropriate outcome.
Lease & Documentation Review
We review the lease, relevant schedules, licences for alterations and available property records to understand the obligations involved.
Property Inspection
A detailed inspection records the condition of the relevant building elements and identifies potential breaches.
Schedule Preparation
Where instructed for a landlord, we prepare a detailed Schedule of Dilapidations setting out the breaches and appropriate remedies. For tenants, we review the claim and assess whether individual items are justified.
Cost & Liability Assessment
Where cost advice forms part of the instruction, repair and reinstatement costs are assessed using KEYS Consulting's benchmark rates developed from more than 30 years of property and construction experience. These are reviewed annually against current market information and our experience of live and completed projects. Interim Schedules would not typically include costs unless a cost assessment has been specifically requested by the client.
Negotiation & Resolution
Negotiation and agreement of a dilapidations claim is a separate instruction from the preparation or review of the Schedule of Dilapidations. Following completion of the schedule or our assessment of a claim, KEYS Consulting can be separately instructed to negotiate on the client's behalf, using the technical evidence and relevant cost information to work towards an agreed commercial resolution.

Frequently Asked Questions
When Should I Seek Interim Dilapidations Advice?
Interim advice can be valuable where deterioration or breaches arise during the lease. For landlords, it can help protect the condition of the asset. For tenants, understanding obligations early provides more time to plan repairs and manage potential expenditure.
When Should a Terminal Schedule Be Prepared?
Terminal dilapidations are generally considered as the lease approaches expiry or once it has ended. The appropriate timing depends on the lease and circumstances, but early preparation gives both parties more opportunity to understand their respective positions.
Can a Tenant Challenge a Dilapidations Claim?
Yes. A Schedule of Dilapidations can be reviewed against the lease, building condition, appropriate repair standard and relevant limitations on recoverable loss. Items that are unsupported or disproportionate can form part of the negotiation.
How Are Dilapidations Costs Assessed?
Where cost advice is required, KEYS Consulting uses benchmark rates developed from more than 30 years of property and construction experience. These are reviewed annually against current market information and our experience of live and completed projects. Interim Schedules of Dilapidations would not typically include costs, although a cost assessment can be provided where specifically requested.

Yes. KEYS Consulting provides independent professional advice to landlords and tenants, with the scope and strategy tailored to the client’s contractual position and commercial objectives.
