Commercial Dilapidations Estimator
A quick-reference educational tool for surveyors and commercial landlords. It illustrates how area, asset type and stated condition can change a planning scenario; it does not price works or establish a claim value.
Asset Parameters
An illustrative scenario calculated from fixed example inputs on this page. It is not based on live market rates and excludes lease terms, Section 18(1), VAT, fees, loss of rent and scope-specific costs.
This output is not legally enforceable. A potential claim needs a lease-specific, itemised schedule and appropriate evidence; seek professional advice on the Dilapidations Protocol and Section 18(1) where they apply.
For comprehensive structural diagnostics, PropertySurvey Pro offers an optional CR1/CR2/CR3/NI condition-rating scale per the RICS Home Survey Standard. See our RICS condition report software page for how the app supports Level 1, 2 and 3 survey workflows.
Build an itemised cost schedule on site
Move beyond rough square-foot multipliers. PropertySurvey Pro™ lets you log granular defects offline, append photos with capture timestamps, record condition ratings, and export an itemised cost schedule as an on-device PDF from your iPad or phone — wording you review and edit before it leaves the device.
Frequently asked questions
What does this commercial dilapidations cost estimator calculate?▾
It produces an indicative baseline figure for a terminal dilapidations liability using three inputs — floor area in square feet, asset type (office, industrial or retail) and the tenant's end-of-lease repair condition. It applies a per-square-foot rate and a condition multiplier and returns a single aggregate estimate live on this page as you adjust the sliders.
Is the estimate a formal valuation or a Scott Schedule?▾
No. The figure is an indicative planning estimate only. It is not a formal valuation, a priced Scott Schedule, or a substitute for a chartered surveyor's assessment. It does not apply a Section 18(1) diminution-in-value cap, professional fees, VAT or loss of rent, so the actual recoverable sum can differ materially.
How accurate are the per-square-foot rates?▾
The rates are illustrative inputs for educational use, not published market averages. They will vary by location, building age, specification and local contractor pricing. For a potential end-of-lease claim, obtain an itemised schedule and cost evidence from an appropriately qualified professional; the lease, Section 18(1) of the Landlord and Tenant Act 1927 and the Dilapidations Protocol may affect the position in England and Wales.
How do I produce a proper itemised schedule on site?▾
PropertySurvey Pro lets you log breaches of covenant offline on site, attach photos with capture timestamps, map condition ratings 1–3, and export an itemised cost schedule as an on-device PDF. AI Polish can expand shorthand notes into report wording that you review and edit before export.
