Scheduled monument consent: a separate consent regime

Planning permission does not allow you to touch a scheduled monument. Works affecting one need scheduled monument consent from the Secretary of State under section 2 of the Ancient Monuments and Archaeological Areas Act 1979, and carrying them out without it is a criminal offence regardless of any permission the council has granted. The two regimes run in parallel and neither substitutes for the other.

For a landowner with a barrow in a field or a moated site in a paddock, this is the consent that governs the day-to-day.

What scheduling protects

A scheduled monument is an ancient monument entered on the schedule maintained by the Secretary of State, advised by Historic England. The range is much wider than the word "monument" suggests: barrows and hillforts, deserted medieval villages, moated sites, ridge and furrow, Roman roads, industrial remains, wartime defences, bridges, crosses and abbey ruins are all on the schedule.

Scheduling protects the monument and the ground it occupies, including buried archaeology within the scheduled area. The boundary is defined on a map held with the entry, and it often includes a margin of land beyond the visible earthwork.

Two points catch people out. Scheduling applies to the land, not to the ownership, so buying the field buys the constraint. And scheduling is recorded as a local land charge, which is how it should turn up on a search, as our note on how obligations appear on title explains.

A building that is both scheduled and listed is controlled through the scheduling regime. Listed building consent is not required for works to a scheduled monument, which avoids a double application but does not lower the bar.

Which works require consent

Section 2 catches a broad set of activities. Consent is needed for works resulting in the demolition, destruction or damage of the monument, for works of removal, repair, alteration or addition, and for flooding or tipping operations on the land.

In practice that includes the things a landowner would not instinctively regard as works. Erecting a fence with driven posts. Cutting a new drainage ditch. Deepening ploughing beyond the depth previously worked. Laying a water pipe. Planting trees, because the roots disturb buried deposits. Removing scrub with a machine. Resurfacing a track that crosses the scheduled area.

It also includes repair. Rebuilding a collapsed section of monastic wall is an alteration and it needs consent even where the intention is preservation.

Where the works sit outside the scheduled area but would affect the setting of the monument, consent is not required. Planning permission is, and Historic England is a statutory consultee on development affecting the site or setting of a scheduled monument under the Development Management Procedure Order 2015.

Who decides the application

The application is made to the Secretary of State with responsibility for heritage, and Historic England administers the process and provides the advice on which the decision is based. The local planning authority does not decide it and cannot grant it.

There is no fee. There is also no determination period equivalent to the eight weeks for a householder planning application, so build the timescale into the programme rather than assuming it will run alongside a planning case.

A consent normally lasts five years from the date it is granted, after which it lapses if the works have not been carried out. Conditions can be attached, and the common ones require archaeological recording, a method statement agreed in advance, supervision by a named specialist, and notification before work starts.

Where consent is refused or granted subject to conditions you cannot accept, there is a right to be heard at a hearing or inquiry before the final decision, which is a different mechanism from a planning appeal.

Class consents and what they cover

Some works are granted consent in advance by the class consents order, which saves an application for routine activity. The classes cover a defined list, and reading it carefully is worthwhile because the limits are tight.

The agricultural class is the one landowners rely on most, and it is narrower than it appears. It permits continuing the same kind of cultivation at the same depth, and it does not permit a change to a deeper or different operation. A field that has been permanent pasture for twenty years cannot be ploughed under this class.

Some classes require prior written notification to Historic England before the works begin. Check the current order rather than a summary, because the classes and the notification requirements have been amended.

The relationship with planning permission

Think of them as two locks on the same door.

Planning permission deals with land use and development in the ordinary way. Scheduled monument consent deals with physical effect on the monument. A scheme may need both, one, or neither, and the sequence matters because a planning permission granted for a scheme that cannot obtain consent is worthless.

Where a development site contains a scheduled monument, the practical approach is to design the built form entirely outside the scheduled area, route services around it, keep construction traffic off it, and secure the monument area as managed open space with a long-term management plan.

Where the monument is near rather than within the site, the setting argument governs. National policy treats scheduled monuments as designated heritage assets of the highest level, so harm to significance through development in the setting requires clear and convincing justification.

An Archaeological Desk-Based Assessment is the usual first document, establishing what is known, what the monument comprises and how far the archaeological interest is likely to extend beyond the scheduled boundary.

Evidence and mitigation expected

An application for consent is a short document with a great deal of supporting material behind it.

1. A description of the monument and its condition, with dated photographs from fixed points.
2. A plan showing the scheduled area, the works and their relationship to known features, at a scale that can be read.
3. A statement of significance covering the evidential, historical, aesthetic and communal value of the monument.
4. A method statement setting out exactly how the works will be carried out, with plant, access routes and ground protection specified.
5. A written scheme of investigation where any ground disturbance is proposed, prepared by a qualified archaeologist.
6. An explanation of why the works are necessary and why less harmful alternatives were rejected.

Where ground disturbance cannot be avoided, expect a condition requiring archaeological field evaluation or a watching brief, with a reporting and archive deposition requirement. That work should be done by an appropriately qualified archaeologist, and councils and the heritage body both expect it.

Geophysical survey is worth offering where the extent of buried remains is uncertain. It is non-intrusive, comparatively quick and it frequently narrows the area in dispute.

An illustrative example

A landowner wishing to install a new stock fence across a field containing a scheduled bowl barrow, with the fence line clipping the scheduled area. The application proposed a realigned fence outside the scheduled boundary for most of its length, with a short section using ground-level anchored posts rather than driven posts where realignment was impossible, a method statement excluding tracked plant from the scheduled area, and a photographic record before and after. Consent was granted with a condition requiring archaeological supervision of the anchored section. This example is illustrative rather than drawn from a specific case.

Offences and enforcement

Carrying out works without consent is an offence under the 1979 Act, as is damaging a protected monument. The penalties on conviction are serious and the court can order restoration where that is possible.

There are limited defences, including that the works were urgently necessary in the interests of health or safety, subject to notification afterwards. Ignorance of the scheduling is a much weaker position than people assume, given that it appears on a land charges search.

Metal detecting on a scheduled monument without written consent is a separate offence under the Act, and it is prosecuted.

If damage has already occurred, the sensible course is to stop, record the position, and approach Historic England directly rather than continuing and hoping. Voluntary reporting and a remediation proposal are treated very differently from discovery after the event. A Heritage Statement prepared by a qualified specialist is the document that frames that conversation properly.
