Answer
What If the Archaeological Condition Is Already Overdue?
If development has started and a pre-commencement archaeological condition has not been discharged, this needs handling immediately and carefully, not quietly.
The honest answer
A breached pre-commencement condition is a planning matter with potential consequences for enforcement, for future discharge and for the saleability and financing of the scheme. The scale of the problem depends heavily on how much ground disturbance has occurred and whether anything of significance has been affected.
The practical route is usually to establish what disturbance has taken place, record what survives, and put a scheme to the authority that demonstrates the archaeological interest can still be properly addressed. Approaching the authority with a reasoned proposal is a substantially better position than being approached by it.
We will tell you honestly what we think the position is, including where we think the outcome depends on the authority rather than on us.
Bring the actual documents to the review
Provide the decision notice, exact condition, approved schemes and a record of work already undertaken. Identify the next proposed ground disturbance. Archaeological advice can inform a proposal, but cannot retrospectively approve works or substitute for the authority's decision.

Before appointing
Turn the requirement into a defined programme decision
Confirm the planning trigger, the area and depth of disturbance, any existing archaeological evidence, and the date that matters to the wider programme. That is the minimum information needed to decide whether the next step is appraisal, evaluation, mitigation or a regulator discussion.

Common questions on this
Should we just carry on and deal with it later?
No. Continued disturbance makes both the planning position and the archaeological outcome worse, and it removes the arguments that would otherwise be available to you.
