Planning appeals in Wales: routes and timescales

A planning appeal in Wales is decided by Planning and Environment Decisions Wales on behalf of the Welsh Ministers, under Welsh procedural rules that differ from the English system in one way that changes how you work. The appellant's full case has to be submitted with the appeal, and the body determines which procedure the appeal follows. If you are used to lodging in England and building the evidence afterwards, that habit will cost you the appeal. This article deals with Wales only. Welsh applications and appeals are assessed against Planning Policy Wales, the Technical Advice Notes and the Welsh development plan.

Who decides appeals in Wales

Planning and Environment Decisions Wales, usually shortened to PEDW, was established in 2021 and handles planning and related appeals and casework in Wales. Inspectors decide most appeals themselves under delegated powers, and the Welsh Ministers decide recovered and called in cases.

The statutory right of appeal against refusal or non determination still comes from section 78 of the Town and Country Planning Act 1990, which applies in Wales as well as England. The procedural machinery around it is Welsh, made by the Welsh Ministers, so the forms, the deadlines and the rules on evidence are set separately.

The development plan is also different. In Wales it comprises Future Wales, the national development framework, any strategic development plan, and the local development plan for the area. National policy sits in Planning Policy Wales with detail in the Technical Advice Notes, and PEDW inspectors cite those rather than the English Framework.

Deadlines, and why you should check rather than assume

Every appeal category has a prescribed period, and those periods are set by the Welsh procedural rules. They are not interchangeable with the English figures, so diarise from the current PEDW guidance for the specific appeal type rather than from an English checklist.

Two deadlines are worth committing to memory because they are statutory and unforgiving. An appeal against an enforcement notice must be made before the date the notice takes effect, under section 174 of the 1990 Act, and there is no discretion to extend it. An appeal against refusal runs from the date on the decision notice, not the date you received it.

Where a decision is late rather than refused, the right to appeal for non determination opens once the determination period has expired without a decision, and the authority's agreement to an extension of time removes that option for the extended period. Read any extension request carefully before you sign it.

The full statement of case at the point of appeal

This is the feature that catches English practitioners out. In Wales the appeal system is front loaded. The appellant submits the full statement of case with the appeal, the local planning authority submits its full case in response, and further evidence is admitted only with permission.

The practical consequences are worth spelling out.

1. Commission any technical work you intend to rely on before you lodge, not after.
2. Draft the statement of case as the primary document rather than as a covering note, because it is the case.
3. Deal with every reason for refusal, including the ones you think are weak, since you may not get a second chance to answer them.
4. Attach the appeal documents in a form a third party can follow, because the case is published.
5. Expect the authority's case to be equally complete, so anticipate the argument rather than reacting to it.

Where a specialist report is central to the appeal, that report needs to be finished and signed by its author before submission. An AI-assisted draft can structure the document and flag the gaps, and a qualified professional has to own the version that goes in.

Choosing, or rather being allocated, a procedure

In England the appellant expresses a preference and the Planning Inspectorate usually follows it. In Wales, PEDW determines the procedure, taking account of criteria in the Welsh rules that look at the complexity of the issues, whether evidence needs testing by questioning, the level of public interest and whether the case raises matters of more than local significance.

You can and should say which procedure you consider appropriate, with reasons tied to those criteria. Asking for an inquiry because the scheme is large will not persuade anyone. Asking for a hearing because two acoustic consultants disagree on a rating level, and the disagreement is decisive, is a reason an inspector can act on.

The questionnaire, core documents and the site

The authority completes an appeal questionnaire and supplies the documents it relied on, including the officer report, consultation responses, relevant policies and the decision notice. Check what arrives against your own file. Missing consultation responses and superseded policy extracts are common, and pointing them out early is easier than arguing about them later.

Assemble a short core documents list and stick to it. An inspector reading a written representations appeal has limited time, and a bundle of four hundred pages with the decisive policy on page three hundred does your client no favours. Quote the operative policy wording in the statement of case and cross refer to the page.

Site visits may be unaccompanied or accompanied depending on whether internal access or a private viewpoint is needed. Say clearly what the inspector needs to see, and from where.

Costs and third party involvement

Costs in Welsh appeals follow the same general principle as in England: an award is made where a party has behaved unreasonably and caused another party to incur unnecessary expense. Refusing without evidence, failing to substantiate a reason for refusal, or withdrawing an objection at the last moment are the familiar grounds. Apply at the right point in the procedure and set out the unreasonable behaviour and the resulting cost specifically.

Interested parties can make representations, and in a hearing or inquiry the inspector may allow them to speak. Because the appellant's case is published in full at the start, local objectors in Wales see the complete argument earlier than they would in England. Write the statement of case knowing that audience will read it.

An illustrative example: an appeal against refusal of four dwellings on a village edge, refused on landscape and highway grounds. The appellant lodged with a completed landscape assessment, a visibility splay drawing signed by a transport consultant and a statement of case answering both reasons for refusal in separate sections. The authority's case conceded the highway point. Because the evidence was complete on day one, the appeal ran as written representations and the concession appeared in the authority's own statement rather than months later.

Preparing evidence that suits the Welsh procedure

Work backwards from the front loading requirement. Before you lodge, you want the technical reports finished, the policy analysis written against Planning Policy Wales and the relevant Technical Advice Note by name, and the development plan policies quoted from the adopted local development plan rather than from an English equivalent.

Where the drafting has been done with tools grounded in English policy, the reviewer has to check the national policy position for Wales. PlanScope's drafting is grounded in national policy and English local plans, so a Welsh appeal statement needs the Welsh framework checked by the professional who signs it. You can find a reviewer through the professional directory, and the report index shows which technical documents sit behind each type of argument.

One honest uncertainty. The procedural detail in Wales has been changed more than once since the Planning (Wales) Act 2015, including the arrangements for fees and forms, so treat any secondary summary, including this one, as a prompt to check the current PEDW guidance rather than as the last word.

This is general guidance rather than legal advice. Check the position with Planning and Environment Decisions Wales or a qualified professional before relying on it.
