A schedule of condition report details the exact conditions of a
property when it is handed over, and usually contains a
photographic record of the conditions.  The schedule will then
be agreed to by both parties and attached with the lease, so that
in the event of any disputes it can be demonstrated whether the
building is still in the same condition.

Both agents and building surveyors can assist with the creation
of the Schedule (in order to accurately reflect the state of the
property).

It's a requirement when leasing to hand back the premises to the
landlord in good condition, and the landlord should never be
expected to pay for damage done by the tenant.  If any work is
required to restore it to leasable condition, the previous tenant
will usually be eligible.

Dilapidation charges can easily run into the thousands (or even
millions) in the case of larger buildings.  This is simply the
cost of rectifying a building once it's been vacated or
surrendered; normally specialist surveyors deal with the
issues.

Can I receive a claim even if there's a Schedule of
Condition?

You can, but the Schedule of Condition should provide a
demonstration that the claim is erroneous, and will reflect fairly
any defects that have occurred during the duration of the
lease.
