Answer
Who Pays for Archaeological Work on a Development?
The developer does. Archaeological work required by a planning condition is a development cost, and it is not recoverable from the planning authority.
The honest answer
The principle in national planning policy is that the applicant provides the information needed to assess the significance of heritage assets affected by their proposal, and funds the recording of what will be lost. Practically, that means archaeology sits in the development budget alongside any other pre-construction obligation.
Because it is a development cost, it is also a negotiable scope. What is not negotiable is whether the condition must be discharged; what is very much open to reasoned argument is how much work, at what intensity, over what area.
Where land is being acquired, this cost belongs in the acquisition appraisal rather than being discovered afterwards. It is one of the few pre-construction liabilities that can be estimated before exchange.
Questions
Common questions on this
Can any of it be recovered or grant funded?
Developer-funded work required by condition is not normally grant funded. Outreach, publication or display elements are sometimes supported separately, but the core fieldwork obligation is not.
