Fast Track Quotation →Dilapidation Costs
Dilapidation costs are the financial consequences of breaching the repair, reinstatement and decoration obligations in a commercial lease. They cover the works needed to put the premises back into the condition the lease requires, or the settlement figure a tenant agrees to pay instead. Understood early, they are manageable; understood late, they can dominate exit planning.
This page sets out what drives the numbers, how a chartered surveyor calculates them, where the statutory caps bite, and how tenants and landlords should approach negotiation. For project-specific support, see the dilapidations surveyor service or the wider dilapidations guide.
What They Are
The cost of putting commercial premises back to the standard required by the lease, or the financial settlement agreed in place of those works.
When They Appear
At or after lease expiry as part of a terminal claim, or in settlement discussions following service of a schedule of dilapidations.
Why They Matter
For many commercial tenants this is the largest single exit cost on a lease, and the number is usually far more negotiable than it first appears.
The key point
The opening cost figure in a landlord schedule is almost never the amount ultimately paid. What the tenant actually pays depends on the lease wording, Section 18, supersession, the evidence on site and the quality of the cost analysis on both sides.

Dilapidation costs can take several forms. They may be the cost of physical works the tenant carries out before lease expiry. They may be the cost of works the landlord carries out after vacant possession and then recovers as damages. They may be a negotiated settlement in which the tenant pays a lump sum in place of works — sometimes called a payment in lieu. For the formal claim that sets out those costs, see the terminal schedule of dilapidations guide.
In every case, the starting point is a proper assessment against the specific lease clauses, and the end point is a figure that reflects actual loss, not a wish-list refurbishment.
Key factors that drive the cost
- Lease wording — the exact repair, decoration, reinstatement and yielding-up clauses.
- Any schedule of condition that limits the standard of repair required.
- The scope and quality of licensed alterations during the term.
- The type of occupancy and the wear profile it produces over the lease.
- The length of the lease and the decoration cycles it covers.
- Market labour and materials rates at the time works are priced.
How the cost is calculated
The calculation is a surveyor's exercise rather than a quantity-surveyor-only one. It has to be tied back to the lease at every stage, because a cost that cannot be justified under the covenants is not recoverable. The starting point is usually a dilapidation report tying each finding to the specific lease obligation.
- Inspection of each element against the specific lease clauses in play.
- Scheduling of each alleged breach with a proportionate scope of works.
- Pricing each item on a realistic rather than wish-list basis.
- Cross-checking against licences to alter, consents and any schedule of condition.
- Testing Section 18 and supersession where they are likely to bite.
Statutory and practical caps
Several concepts can reduce — or occasionally eliminate — recoverable cost, regardless of the opening schedule total.
- Section 18 of the Landlord and Tenant Act 1927 caps damages at the diminution in value of the reversion.
- Where redevelopment or substantial alteration is planned, the second limb of Section 18 can eliminate recovery entirely.
- Supersession can strip out individual items that would have been overtaken by the landlord's planned works.
- A schedule of condition can cap the standard of repair at the state of the premises at lease start.
- Unreasonable or over-specified works cannot be recovered in full, even where a breach is proven.
Section 18 cap
Damages are limited to the diminution in value of the landlord's reversion caused by the breaches. Where that is lower than the cost of works, recovery is limited to the diminution.
Supersession
Items that would have been overtaken by the landlord's intended works are not recoverable, because the tenant's breach has caused no real loss.
For more detail see the guides on Section 18 and supersession.
Negotiating the final figure
Negotiation of dilapidation costs is rarely a single event. It usually proceeds line by line, informed by the Dilapidations Protocol, and often concludes at a without-prejudice meeting once both sides have exchanged their cost positions.
- Treat the schedule total as an opening position, not a bill.
- Price each item independently rather than accepting the landlord's rate card.
- Raise Section 18, supersession and any schedule of condition early.
- Document the actual condition on vacation with dated photographs.
- Engage promptly under the Dilapidations Protocol to avoid costs criticism later.
Managing cost exposure over time
For tenants, the most effective cost-control strategies are the ones used across the life of the lease, not the ones invented at the end.
- Understand the lease obligations at the start of the term, not at the end.
- Budget a dilapidations provision over the life of the lease rather than facing one-off exposure.
- Commission an independent dilapidation report 12 to 18 months before expiry.
- Plan reinstatement and decoration works with enough lead time to tender properly.
- Consider payment in lieu of works where the landlord intends to refurbish regardless.

Need an independent cost view?
Whether you are preparing a claim, responding to one, or simply trying to budget accurately for lease end, an independent cost review will almost always change the picture — usually in the tenant's favour, sometimes in the landlord's.
