Commenting on listed building consent next door

If your neighbour has applied for listed building consent, you can comment, but the test the council applies is narrower than you might expect. Listed building consent is granted or refused on the effect of the works on the special architectural or historic interest of the building. Overlooking, noise, parking and loss of light are not part of that assessment at all. A comment about the loss of your afternoon sun will be read, logged and then set aside, because the decision maker has no power to take it into account under this consent.

Where the same scheme also needs planning permission, those amenity points belong in a separate comment on that application. Many people make one representation covering everything and lose half of it.

What listed building consent controls

Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 makes it an offence to carry out works for the demolition, alteration or extension of a listed building in a way that affects its character as a building of special architectural or historic interest, without consent.

The listing covers the whole building, inside and out, not just the parts described in the list entry. It also extends to objects and structures fixed to the building and to certain structures within its curtilage that pre-date July 1948. So an application might cover internal partitions, a staircase, a chimneypiece, window replacement, a rear extension or the demolition of a garden wall.

Three consequences for a neighbour. Internal works you cannot see from your property are still assessable, and are often the most damaging. Works to a boundary wall between your properties may need consent. And the grade matters to the weight given to harm, with Grade I and II* buildings attracting the most scrutiny, though the statutory duty applies at every grade.

The statutory test the authority applies

Section 16 of the 1990 Act requires the authority, in considering whether to grant listed building consent, to have special regard to the desirability of preserving the building or its setting or any features of special architectural or historic interest which it possesses.

National policy builds on that with the familiar structure: great weight to the conservation of a designated heritage asset, and a distinction between substantial harm, which requires exceptional or wholly exceptional justification depending on the asset, and less than substantial harm, which is weighed against public benefits. Cite the NPPF edition you are relying on, since the Framework was renumbered in December 2024 and re-issued on 17 August 2026 with policy codes replacing paragraph numbers.

The practical question for a comment is therefore not "do I like this" but "what fabric or feature of interest is lost, and has the applicant justified it". That is a question you can often answer better than the officer, because you may know the building.

Publicity and who is notified

The Development Management Procedure Order sets the publicity requirements. For listed building consent the authority must publish a notice in a local newspaper and display a site notice, and in practice most authorities also write to immediate neighbours, though direct notification is not guaranteed for this type of consent in the way it often is for planning applications.

The comment period is normally 21 days from the later of the notices. Comments received after that are usually still taken into account if the application has not been determined, but there is no entitlement to have them considered.

If you want to be sure of hearing about applications on a particular building, check the authority's weekly list of registered applications. Most publish one, and it is a more reliable way to track a neighbouring property than waiting for a letter. Our note on whether neighbours are reconsulted on amended plans covers what happens when the scheme changes after you have commented.

Significance and harm as the framework

A comment that engages the statutory test is structured around significance. Identify the feature, say why it contributes to the special interest, then say what the proposal does to it.

Features that commonly carry significance in a modest listed house:

• original joinery, including staircases, doors, architraves and panelling
• historic plan form, and the sequence of rooms as originally arranged
• original window joinery and glazing, including crown or cylinder glass
• lime plaster and lime mortar, and the breathability of the construction
• original roof structure, floorboards and chimneypieces
• the hierarchy of the elevations, with front, side and rear treated differently

The weakest comments assert that a building is historic and should not be changed. The strongest identify a specific element, explain its contribution, and point to the part of the application that removes it. Where the application documents are silent about an element, say so, because an incomplete assessment of significance is a legitimate ground for the authority to ask for more.

Where amenity arguments do not apply

This is the point most worth absorbing. The following are not material to a listed building consent decision:

Where works affect a shared or boundary wall, the Party Wall etc. Act 1996 runs alongside and gives you rights that planning does not, including the appointment of surveyors and an award setting out how the work is done. That is a separate process with its own notices, and the council will not administer it for you.

Check whether a planning application has also been submitted for the same scheme. An extension to a listed building almost always needs both, and the two applications are usually determined together but assessed against different tests. Comment on both, separately, and label each comment with the right reference.

Consultation with the national heritage body

Historic England is a statutory consultee on listed building consent applications in defined circumstances, broadly for works to Grade I and Grade II* buildings and for certain works to Grade II buildings involving demolition. For most Grade II alterations the authority's own conservation officer provides the specialist advice.

The national amenity societies, which include bodies covering particular architectural periods, are notified where an application involves the demolition of any part of a listed building. They are often the most effective commenters because they comment on significance and precedent rather than on amenity, and their letters are quoted in officer reports.

Nothing stops you drawing an application to the attention of the relevant society yourself, with the reference number and a short note on what is proposed. If the works would remove something of real interest, that is frequently the most useful thing a neighbour can do.

Making a comment that engages the test

A workable structure for a representation, kept to one page:

1. State the application reference, the address and the date of your comment.
2. Say what your interest is, for example that you live next door, without going into history with the applicant.
3. Identify each element of special interest you are concerned about, with its location in the building.
4. Explain briefly why that element contributes to the special architectural or historic interest.
5. Say what the application does to it, citing the drawing number or paragraph where it appears.
6. Note anything missing from the applicant's heritage assessment.
7. Say what you are asking for: refusal, amendment, a condition requiring recording, or a condition requiring a sample panel or detail approval.

Ask for something achievable. Officers can condition a scheme far more readily than they can refuse one, and a well-aimed request for a recording condition or for approval of joinery details often produces a better outcome than a general objection. Our guide to reading a decision notice as a neighbour explains how to check afterwards which of your points landed, and breach of condition notices covers what happens if the approved details are not followed.

Where you need to understand which documents an applicant should have supplied, the full index of report types sets out what a heritage statement and an archaeological assessment contain.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
