When do you need a dilapidations surveyor?

The single best moment for tenant-side input. A Schedule of Condition prepared and appended to the lease at grant qualifies the repairing covenant by reference to the documented baseline, neutralising most of the future dilapidations exposure before it ever crystallises.

Landlords can serve an interim Schedule of Dilapidations during the term where the disrepair is materially affecting the value of the reversion. Interim claims require a different defence to terminal claims (the Section 18 cap operates differently mid-term) and need specialist response.

The earliest tenants should be thinking about terminal dilapidations is 12–18 months before lease expiry. A pre-expiry strategy review establishes the likely exposure, the landlord's probable intentions, and the choice between yield-up works (do the work) and a damages negotiation (pay the diminution).

The Quantified Demand is the formal opening of the dilapidations claim under the Pre-Action Protocol. It is the moment specialist tenant-side instruction becomes urgent. The tenant has a defined window to respond, and the response shapes the negotiation.

Following the response to the Quantified Demand, the parties' surveyors typically work through a Scott schedule, an item-by-item record of agreed and disputed positions. Specialist surveyor input at this stage is the principal driver of settlement value.
