Cost and scope
Archaeological Survey Costs for Planning Permission
A planning-stage survey budget should expose uncertainty early, then replace it with evidence before it reaches a construction or land-acquisition decision.
- Best use
- Land appraisal, planning and early procurement
- Output
- A proportionate next step and stated assumptions
- Avoid
- Treating a provisional allowance as a final excavation price
The next decision
There is no verified Cambridge rate card on this site. ‘Survey’ may mean assessment, geophysics or intrusive evaluation; each needs its own scope and price. Later mitigation is a separate decision, not an assumed survey inclusion.
Compare five budgets, not one survey total
Desk-based assessment buys an interpreted evidence base and impact assessment: check HER fees, historic sources, site visit and revision allowance. Geophysics buys survey and interpretation over an agreed accessible area: identify method, target, unsuitable ground and un-surveyed areas. Trial trenching buys approved intrusive sampling and reporting: price trench length/width, plant, backfilling, welfare, services and reinstatement responsibilities.
Mitigation depends on findings, significance and development impacts. Separate agreed fieldwork from additional-work instructions, specialist assessment, analysis and archive obligations. A post-excavation allowance is not automatically a fixed final-analysis price; agree what assessment will do to the later budget.
Compare quotes at the same tax basis and completion point. Reconcile each commissioned stage price, provisional allowance, exclusion and tax basis in one budget. Keep unpriced stages visible; an apparent total is not complete if later analysis or archive work is missing.

What a planning-stage survey allowance needs to cover
An archaeological survey for planning permission is not one universal product. It may begin with a desk-based assessment, use geophysics where the ground and target suit it, and move to trial trenching where the development needs evidence of what is actually present. The correct allowance follows the planning question, not a generic menu of services.
A usable figure separates mobilisation, access and welfare, plant and machine time, field staff, reporting, specialist assessment, archive and the approvals needed before the next development stage. That distinction matters because a low fieldwork figure can simply move cost into exclusions or later reporting.
How to keep the cost decision commercial
Ask for the proposed method, the assumptions behind it, the decision it will unlock and the consequences if the evidence is stronger than expected. For a development team, the point of the first survey is to convert an unpriced planning risk into a programme and procurement decision.
Where a site is being acquired or submitted for planning, the useful question is not whether archaeology can be made cheap. It is whether the available evidence is sufficient to protect the appraisal, layout and critical path before commitments harden.

Questions
Common questions on this
Can an archaeological survey cost be estimated before planning permission?
Yes, but the useful output is an allowance with stated assumptions, not a fixed quotation. Existing HER evidence, site area, ground conditions and the proposed disturbance determine whether the next proportionate step is desk-based assessment, geophysics, trial trenching or a combination.
What usually makes an archaeological survey cost more?
Access, trench percentage, overburden, services, crop or ground conditions, programme restrictions and the amount of reporting required all affect the budget. A larger site is not automatically more expensive if the evidence, access and method are simpler.
Does the survey price include later excavation?
Usually not. Evaluation is intended to establish whether later mitigation is needed and, if it is, to make that next stage more definable. A scope should state clearly where fieldwork, reporting, archive and condition-discharge responsibilities end.
Project review
Need a survey allowance that can survive scrutiny?
Send the planning position, site plan and any existing survey evidence. We will identify the next proportionate step and the assumptions that need to be priced.
