Scheduled monument consent and who decides it

7 min readBy PlanScope Editorial Team

Works to a scheduled monument need consent from the Secretary of State, not the council. Here is what counts as works, where class consents help, and what the pack contains.

Scheduled monument consent is decided nationally, not by your council. Works to a scheduled monument need written consent under section 2 of the Ancient Monuments and Archaeological Areas Act 1979, granted by the Secretary of State, with applications handled and advised on by Historic England. The local planning authority has no role in granting it, which surprises most landowners who assume the planning department controls everything on their land.

Carrying out works without consent is a criminal offence, and the scheduled monument consent process is not something to discover after a contractor has put a trench through a ringwork.

Consent is needed for any works resulting in the demolition, destruction, damage, removal, repair, alteration or addition to a scheduled monument, and for flooding or tipping operations on the land within the scheduled area. The test is physical interference with the monument, not whether the work is visible.

That catches a wider range of farm operations than people expect:

  • new drainage, pipe runs, water troughs and cable trenches
  • fence posts, gate posts and stock handling installations
  • new or deepened ploughing, subsoiling and mole draining
  • tracks, hardstanding and the storage of materials
  • tree planting and the removal of stumps
  • works to a standing structure, including repointing and consolidation

Scheduled areas are mapped on the National Heritage List for England, and the entry describes what is designated. Read the map carefully, because scheduling lines are drawn to the monument's extent as understood at designation and often follow field boundaries loosely.

Who determines the application

Applications go to Historic England, which advises the Secretary of State for Culture, Media and Sport. The decision is the Secretary of State's. Historic England's inspector of ancient monuments will usually want to discuss the proposal before an application is submitted, which is worth taking up because it is free and it shapes the application you end up making.

There is no local committee, no neighbour consultation in the planning sense, and no appeal to the Planning Inspectorate. Where consent is refused there are limited routes of challenge, so the pre-application conversation does the work that negotiation with a case officer would do on a planning application. Consultees respond in a similar fashion to planning, and our explainer on standing advice from planning consultees is a useful comparison for how generic guidance is applied.

Consent can be granted with conditions, commonly requiring archaeological supervision, a written scheme of investigation, a time limit, and notification before works start.

Class consents and their limits

Some works are already consented by order, which is the reason most farmers never apply. The Ancient Monuments (Class Consents) Order covers defined categories, and the one that matters on farmland permits agricultural, horticultural and forestry works of the same kind as those lawfully carried out in the preceding six years.

Two limits catch people out. The work has to be the same kind as before, so ploughing land that has been ploughed to the same depth is covered while deepening the cultivation is not. And the six-year period is counted backwards from the work, so a field in permanent pasture for a decade has lost the benefit entirely.

Other classes cover works by specified drainage and navigation bodies, works essential for safety or health, repairs to machinery, and archaeological work carried out by or on behalf of Historic England. Subsoil ploughing, drainage works and the planting or uprooting of trees are expressly outside the agricultural class.

Where a class consent applies, keep your own evidence of the previous operation. A cropping record or a contractor's invoice showing depth and date is the difference between a defensible position and an argument.

Relationship with planning permission

The two regimes are separate and neither substitutes for the other. Scheduled monument consent does not authorise development, and planning permission does not authorise works to a monument. A scheme needing both has to obtain both.

Where development affects only the setting of a monument, no scheduled monument consent is needed. The setting case is made entirely through the planning application, supported by a Heritage Statement and usually an Archaeological Desk-Based Assessment.

Listed building control steps aside for scheduled monuments. Where a structure is both listed and scheduled, listed building consent is not required for works to it, because the monument regime takes precedence. If you are unsure which designations apply, check the list entry before assuming.

Criminal liability for unauthorised works

Section 2 of the 1979 Act makes it an offence to execute, cause or permit works needing consent without it. There is a separate offence of damaging a protected monument. Liability can extend to the person who permitted the work, which means a landowner who let a contractor operate without checking is exposed alongside the contractor.

Penalties are set by the court, and in serious cases include substantial fines. The practical consequences are often worse than the fine: a halted operation, an archaeological recording exercise at your cost, remediation requirements, and in some cases a prosecution reported locally.

Ignorance is a weak defence. The list entry is public, and a buyer's searches should reveal scheduling, so a purchaser who did not look is in a poor position.

An illustrative case on a farmed field monument

Take an illustrative example. A farm holds a scheduled Iron Age enclosure within an arable field, ploughed to 200 millimetres for years under the same rotation. The farmer wants to install a new ring main with a trench across the field and a trough inside the scheduled area, and to move to a deeper cultivation.

The ploughing change and the trench both need consent. The historic ploughing was covered by the class consent only at its established depth and kind, and the trench is a new intrusive operation. The sensible sequence is a conversation with Historic England's inspector, a plan showing the scheduled boundary and the proposed works, and an application that relocates the trough outside the scheduled area and routes the main around the monument.

That application is likely to succeed because it avoids the asset. An application to run the trench through the centre, with a watching brief offered as mitigation, is a far harder case, because avoidance was available.

Assemble a short, precise pack:

  1. A location plan and a detailed plan showing the scheduled boundary and the works, to scale.
  2. A description of the works, including depths, machinery and ground disturbance.
  3. A method statement, with any proposed archaeological mitigation and supervision.
  4. Photographs of the current condition of the affected area, dated.
  5. A statement of why the works are needed and what alternatives were considered.
  6. Any archaeological information already held, including a desk-based assessment or earlier evaluation results.

Alternatives are the part applicants skimp on. Historic England assesses whether the harm is necessary, so showing that you tested a route avoiding the monument, and explaining why it does not work, is more effective than asserting that the chosen route is the only option.

Where a standing structure is involved, a measured record of the existing fabric is usually expected, and Historic Building Recording to the appropriate level may be required by condition. For earthwork and buried monuments, the mitigation is usually archaeological rather than architectural, and should be designed with the county archaeologist as well as Historic England.

One honest uncertainty: how much mitigation is enough varies with the monument's condition and rarity, and two superficially similar cases can be treated differently. Early engagement is the only reliable way to find out.

Frequently asked questions

Who grants scheduled monument consent?

The Secretary of State for Culture, Media and Sport, on the advice of Historic England, which administers the application process. The local planning authority has no power to grant it. There is no appeal to the Planning Inspectorate, so pre-application discussion with Historic England's inspector of ancient monuments carries the weight that negotiation with a case officer would on a planning application.

Do I need consent to plough a scheduled monument?

Not where the ploughing is the same kind, at the same depth, as work lawfully carried out in the preceding six years, which is covered by class consent. Deepening cultivation, subsoiling, drainage and tree planting fall outside it. Keep records of previous operations, because the burden of showing the class consent applies rests with you.

Does planning permission cover works to a scheduled monument?

No. The two regimes are separate, and a scheme needing both has to obtain both. Planning permission does not authorise damage to a monument, and consent does not authorise development. Where a proposal affects only the setting of a monument, no consent is needed and the case is made through the planning application.

Is listed building consent also needed if a structure is both listed and scheduled?

No. Where a building is a scheduled monument, works to it are controlled under the ancient monuments regime rather than listed building control, so listed building consent is not required for those works. Check the list entry to confirm exactly what is scheduled, because scheduling and listing boundaries do not always coincide.

What happens if works are carried out without consent?

It is a criminal offence under section 2 of the Ancient Monuments and Archaeological Areas Act 1979 to execute, cause or permit such works, with a separate offence of damaging a protected monument. Liability can reach the landowner who permitted the work. Expect the operation to be stopped and recording or remediation required at your cost.
