When Historic England must be consulted on an application
Grade I and II consent applications go to Historic England as of right. Grade II applications only go where demolition is involved. Here is how the triggers work and what they do to the programme.
Historic England consultation on a listed building application is compulsory in defined circumstances and discretionary in most others. The line falls, broadly, at grade. Applications for listed building consent affecting Grade I and Grade II* buildings go to Historic England as a matter of course. Grade II applications only go where demolition is involved. Alongside that sits a separate notification duty to the Secretary of State, which is what puts a call-in on the table and adds a fixed pause to your timetable. Knowing which limb applies to your case tells you whether to allow eight weeks or sixteen.
Where the consultation duties come from
Three instruments do the work, and they cover different applications.
The Planning (Listed Buildings and Conservation Areas) Act 1990 provides the framework for listed building consent and gives the Secretary of State the power to call in an application for their own determination.
The Town and Country Planning (Development Management Procedure) (England) Order 2015 lists statutory consultees for planning applications in its schedules, and that is where Historic England appears in relation to development affecting scheduled monuments, Grade I and II* listed buildings and their settings, Grade I and II* registered parks and gardens, and World Heritage Sites.
The arrangements for handling heritage applications direction does the equivalent job for listed building consent and conservation area demolition, setting out who must be consulted and when the council must notify the Secretary of State before granting consent. Read the current direction rather than a summary of it, because the triggers have been revised and the detail is where the programme risk lives.
Grade thresholds that trigger a referral
For listed building consent, the pattern is straightforward once you have it.
| Grade | Works | Historic England consulted |
|---|---|---|
| I | All listed building consent applications | Yes |
| II* | All listed building consent applications | Yes |
| II | Alteration or extension only | No, unless the council chooses |
| II | Demolition of the building or a substantial part | Yes |
Grade II accounts for the great majority of listed buildings, so most consent applications never reach Historic England at all. That has a practical consequence. On a Grade II application, the conservation officer's view is effectively the heritage view, and the quality of your Heritage Statement is doing more work than it would on a higher graded asset.
For planning applications rather than consent applications, the trigger is the effect on the asset, including its setting, and the grade thresholds in the 2015 Order apply. Development near a Grade II listed building does not go to Historic England. Development affecting the setting of a Grade I building does.
External works, internal works and the Grade II line
Listing covers the whole building, inside and out, along with objects and structures fixed to it and pre-1948 structures within its curtilage. That is why internal alterations to a Grade II building need consent even though nothing changes on the elevation.
What the consultation direction turns on is not internal against external. It is demolition against alteration. Stripping out a Grade II interior wholesale is capable of amounting to demolition of a substantial part, and where it does, the referral duty engages.
That distinction is argued more often than it is decided. If your scheme removes a principal staircase, a chimney stack or a structural cross wall, assume the council may treat it as demolition in part and plan for the referral. The article on internal alterations that harm significance covers where the threshold usually sits.
Demolition in a conservation area
Demolition of an unlisted building in a conservation area, above the size thresholds, requires planning permission as relevant demolition. Carrying it out without permission is a criminal offence rather than a matter for an enforcement notice.
The consultation arrangements for conservation area demolition sit in the same direction, and the national amenity societies are the bodies most often engaged. Historic England's involvement is more limited than on listed building applications unless a higher graded asset or a World Heritage Site is affected.
Notification to the Secretary of State and the call-in risk
This is the limb consultants underestimate. Where the direction applies, a council that proposes to grant listed building consent must first notify the Secretary of State and then wait, so that the application can be considered for call-in under the 1990 Act.
The notification is not a formality. It happens after the committee or the delegated decision, at the point everyone assumes the consent is issued, and it adds a fixed period to the programme during which consent cannot lawfully be granted.
Two things reduce the risk of a call-in. A scheme that Historic England has not objected to, and a decision notice that engages properly with the statutory duty rather than reciting it. Where harm is contested, the reasoning in the officer report matters, and the sections 66 and 72 duties are the frame the Secretary of State will read it against.
The national amenity societies
Six national amenity societies have a formal role where an application involves demolition of a listed building in whole or in part. They cover different periods and building types, and their interest follows the date of the building rather than its grade.
They are consultees with expertise, not objectors by default. A society that receives a well-evidenced statement of significance and a clear justification will often confirm no comment. A society that receives a thin document will ask for a measured survey and a fabric analysis, and the council will usually wait for the answer.
Engage them directly where the building falls squarely in one society's period. A conversation before submission costs an hour and removes a round of consultation comments.
What consultation does to your timetable
Statutory consultees have 21 days to respond. That period does not extend the eight or thirteen week determination period, which is why councils routinely ask for an extension of time on heritage cases.
Build the sequence into the client's programme honestly at the outset:
- Pre-application advice, where the asset is Grade I or II* or the harm is contested.
- Submission and validation.
- Consultation, 21 days, running alongside publicity.
- Officer report and decision, with an extension of time likely on anything contested.
- Notification to the Secretary of State where the direction requires it, with a fixed waiting period before consent can issue.
- Consent issued, or the application called in.
An illustrative example. A Grade II* church hall conversion is submitted in January with an expected decision in March. Historic England is consulted as of right, asks for a measured survey of the roof structure, and the applicant agrees an extension of time to June. The council resolves to grant, notifies the Secretary of State, and the consent issues in July. Nothing went wrong. The programme was simply written as though the statutory steps did not exist. Dates here are illustrative.
Engaging before you submit
Historic England offers pre-application advice, and on Grade I and II* cases it is close to essential. The objective is narrow: find out what evidence they will want, and whether the principle of the intervention is acceptable, before the design is fixed.
Where harm is likely to be contested, get the significance assessment right first. Everything downstream, including whether the case falls into the substantial harm test or the less than substantial one, follows from it.
Heritage documents are ones councils expect a suitably qualified author to prepare, and professional review is strongly advised. An AI-assisted draft can assemble the policy framework, the structure and the questions a consultee will ask, then flag the fabric evidence it does not hold, which shortens the unbillable part of a heritage submission.

Frequently asked questions
Does every listed building consent application go to Historic England?
No. Applications affecting Grade I and Grade II buildings do. Grade II applications go only where demolition of the building or a substantial part of it is involved. For alterations and extensions to a Grade II building, the council's conservation officer is usually the only heritage view in the process.
Do internal alterations trigger consultation?
Not by themselves. Listing covers the interior, so internal works to a Grade II building need consent, but the consultation trigger turns on whether the works amount to demolition in whole or in part. Removing a principal staircase, chimney stack or structural cross wall may cross that line, so plan for a referral.
What is notification to the Secretary of State?
Where the heritage applications direction applies, a council proposing to grant listed building consent must notify the Secretary of State and wait before issuing it, so the application can be considered for call-in. It happens after the decision is resolved, adds a fixed period to the programme, and is routinely forgotten.
Which amenity societies have to be consulted?
Six national amenity societies have a formal role where an application involves demolition of a listed building in whole or in part. Their interest follows the period and type of building rather than its grade. Approaching the relevant society before submission usually removes a round of consultation comments.
Does consultation extend the determination period?
No. Statutory consultees have 21 days to respond, and that runs within the eight or thirteen week period rather than adding to it. In practice, contested heritage applications are almost always decided under an agreed extension of time, so build that into the client's programme from the start.
