Key takeaways
  • Dilapidations claims are built up from the cost of repairs, redecoration and reinstatement, so bigger and more altered premises attract bigger claims.
  • On a mid-size commercial unit a claim can run into tens of thousands of pounds.
  • The opening figure is a negotiating position, not a final bill.
  • Challenging items, supersession and the Section 18 cap typically bring the figure down, often substantially.

The number on a Schedule of Dilapidations can be frightening: mid-size commercial units routinely attract claims in the tens of thousands. But that opening figure is a negotiating position, not a bill, and what a tenant actually pays is usually a good deal less. Here is what drives the cost, and how it comes down.

What drives the size of a claim

  • Size of the premises. More floor area means more potential repair and redecoration.
  • Condition and use. Heavy use and neglected maintenance push the figure up.
  • The lease terms. A full repairing obligation and redecoration clauses widen what can be claimed.
  • Reinstatement. Removing tenant fit-out and returning the property to its original layout can be a big line.

Typical ranges

Every property is different, but as a rough steer for UK commercial premises:

PremisesIndicative claim range (guide only)
Small unit or officea few thousand pounds
Mid-size unit (for example a ~10,000 sq ft warehouse)tens of thousands of pounds
Large or heavily altered premiseshigher, sometimes exceeding a year’s rent

These are indicative opening figures, not what a well-advised tenant ends up paying.

Why the opening figure is not the bill

A Schedule of Dilapidations is the landlord's starting position, prepared from the cost of every item of work. It is meant to be scrutinised. Under the Dilapidations Pre-Action Protocol, both sides are expected to engage item by item, and most claims settle well below the opening number.

How the figure comes down

  • Challenging items that are not your responsibility under the lease, or that are overstated.
  • Supersession, where the landlord's own planned works would replace the repairs anyway.
  • The Section 18 cap. Section 18 of the Landlord and Tenant Act 1927 limits damages to the loss in value caused by the disrepair, which can be far below the cost of works.
  • A Schedule of Condition, if one was taken at the start, caps liability for pre-existing defects.

What a dilapidations surveyor costs

Fees depend on the size of the property and the complexity of the claim, starting from a few hundred pounds for a straightforward matter. Set against a claim in the tens of thousands, the surveyor's fee is usually a small fraction of the reduction they achieve.

Getting help early

The earlier a surveyor reviews the schedule, the more room there is to challenge and negotiate. ComSurv matches you with RICS-qualified surveyors who handle dilapidations, and you can verify regulation via RICS Find a Surveyor.

Frequently asked questions

How much is a typical dilapidations claim?+
It depends on the size and condition of the premises and the lease terms. On a mid-size unit, opening claims often run into tens of thousands of pounds, though what a tenant actually pays is usually much less.
Is the figure on the schedule what I have to pay?+
No. It is the landlord’s opening position, prepared from the cost of works. It is meant to be challenged, and most claims settle well below it.
How can I reduce a dilapidations claim?+
By challenging items that are not your responsibility or are overstated, applying supersession where the landlord’s own works would replace the repairs, and applying the Section 18 cap. A surveyor does this for you.
Does a Schedule of Condition reduce a dilapidations claim?+
Yes. If one was taken at the start of the lease, it caps your liability for defects that pre-dated your tenancy, which can significantly reduce the claim.
