A site inspection allows the decision-maker or Inspector to understand the site and its surroundings. It is an evidential viewing exercise, not an opportunity for a party to make an additional speech or introduce arguments outside the proper procedure.

Where a particular viewpoint, route or physical feature is important, identify it clearly in the written evidence and follow any case-specific instructions about suggested inspection locations.

For appeals relating to applications made on or after 1 April 2026, Planning Inspectorate guidance emphasises that appeals are generally determined on the basis of the original application. New technical evidence not previously available to the local planning authority and interested parties should not normally be introduced.

The applicable procedure and directions for the particular appeal must be checked, because the Inspectorate can require information and different appeal routes have different opportunities for further submissions.

Both are procedures available to the Planning Inspectorate, but an inquiry is generally more formal and is suited to cases where evidence needs detailed testing, including through witnesses and cross-examination. A hearing is normally a more inquisitorial discussion led by the Inspector.

The Inspectorate selects the procedure appropriate to the case. Parties should follow the timetable and procedural directions rather than assume that a particular level of public opposition will itself result in an inquiry.

An objector does not have the same statutory planning appeal right as an applicant. A legal challenge may nevertheless be possible in appropriate circumstances, but it is a challenge to the lawfulness of the decision rather than a fresh planning merits appeal.

Strict time limits and specialist procedural rules can apply. Anyone considering court proceedings should obtain appropriate legal advice promptly.

Third parties do not normally acquire their own right to appeal merely because they objected to the original application.

If the applicant appeals, however, interested people can have a further role under the applicable appeal procedure.

First establish which procedural regime applies.

Planning Inspectorate guidance distinguishes appeals relating to applications dated on or after 1 April 2026 from earlier applications. Most appeals under the newer regime begin through written representations, with the Inspectorate deciding whether another procedure is required.

Read the appeal start letter immediately.

It sets the procedure and timetable. Check whether previous representations will be forwarded and whether fresh or updated representations are permitted. For hearing or inquiry cases, note the specific interested-person deadline.

Do not assume the appeal is a complete restart.

Focus on the reasons for refusal, appellant's grounds, changes in evidence or policy and matters that remain genuinely disputed. If the council's defence no longer covers an issue important to the community, consider whether the campaign needs to present that evidence itself.

Rule 6 status is relevant to certain planning inquiries where an interested group needs to participate as a principal party rather than only as a member of the public.

It brings greater procedural involvement but also substantial responsibilities.

A Rule 6 party may be expected to provide a statement of case, proofs of evidence and participate in case management and the inquiry timetable.

The current Planning Inspectorate procedure for relevant inquiry appeals includes a Case Management Conference and deadlines for proofs. This is a significant commitment of time and document discipline.

Seek the status because the group's evidence needs independent presentation or testing, not because the title sounds more influential.

Before applying, identify witnesses, resources, issues, document management and who can attend throughout the necessary sessions. A poorly prepared principal party can weaken rather than strengthen a campaign's presentation.

A hearing is a structured discussion led by the Inspector.

The Inspector identifies the issues from the evidence and representations and controls the discussion. It is intended to explore matters without the full formality of an inquiry.

An inquiry is the most formal planning appeal procedure.

Planning Inspectorate guidance describes it as providing formal testing of evidence, commonly through questioning or cross-examination of expert and other witnesses. Parties may be represented by advocates.

Campaign preparation should reflect the procedure.

For a hearing, prepare concise issue notes and document references and be ready to answer the Inspector's questions. For an inquiry, witnesses need coherent proofs, supporting documents and a clear understanding of the evidence they can defend under questioning.

Watch for the appeal notification immediately after an inquiry appeal starts.

Under current Planning Inspectorate procedure, the Local Planning Authority must notify interested people who commented on the application. For relevant inquiry appeals, that notice tells them that an appeal has been made, that their earlier representation will be forwarded, how to make further representations and that a request for Rule 6 status should be made at that time.

Decide whether the group wants to speak as an interested party or become a Rule 6 party.

An interested person can ask to speak at the inquiry. Planning Inspectorate guidance says there is not generally a legal right for every interested person to speak, but the Inspector will normally allow it. A group wanting a leading role, its own witnesses, main-party documents and the ability to cross-examine should consider Rule 6 status.

If seeking Rule 6 status, write to the case officer early.

The request should identify who the group represents, why Rule 6 status is sought and what substantive contribution it can make that is not already covered by another party. The Inspectorate normally grants Rule 6 status to groups rather than individuals. If granted, a statement of case is normally required within the period specified by the Inspectorate.

If not seeking Rule 6 status, still register the intention to speak.

Planning Inspectorate guidance says it is important to be present when the inquiry opens because the Inspector asks which interested people wish to speak and registers their names. If attendance throughout a long inquiry is impossible, tell the Inspector at the start so that, where practicable, arrangements can be made for the representation to be heard at an appropriate point.

Do not wait until the first morning if the case officer is already seeking participation details.

Respond to advance correspondence and provide the speaker's name and contact details. Turning up at the opening is a safeguard described in the guidance, not a substitute for complying with earlier directions or deadlines.

Rule 6 status makes an interested group a main party to an English planning inquiry.

The Planning Inspectorate treats a Rule 6 party alongside the appellant, Local Planning Authority and other main parties for procedural purposes. It receives main-party documents and can take a substantive role in the inquiry, including calling witnesses and cross-examining evidence.

It is not necessary merely to make a short community statement.

Interested people can normally ask the Inspector for permission to speak without becoming a Rule 6 party. Rule 6 is more appropriate where a campaign has a distinct evidential case, needs to call technical or local witnesses or intends to test another party's evidence.

The application for status should explain added value.

The Inspectorate asks groups to state whom they represent, why they want the status and what they bring that another party may not. Groups should also provide the organisational information requested by the Rule 6 guidance. It is unusual for individuals to be granted the status.

Rule 6 creates obligations as well as rights.

A party can be required to submit a statement of case, proofs of evidence and other inquiry material, participate in case management and comply with document exchange and deadlines. Campaigns should not request the status unless they can resource the role properly.

Prepare before asking.

Identify the issues the group will cover, witnesses, advocate or spokesperson, document controller and availability. Contact the council to understand its case so that the campaign can explain why its participation will add something substantive rather than duplicate the Local Planning Authority.

There is generally no ordinary third-party right of appeal against the grant of planning permission in England. The applicant has statutory appeal rights in specified circumstances, for example following refusal or non-determination.

A person challenging an approval may need to consider judicial review or another specialist legal route, which is different from a planning merits appeal and has strict legal tests and time limits. Independent legal advice should be obtained promptly where a challenge is being considered.
