Pre-application consultation for major development in Wales

This article is about Wales. Pre application consultation in Wales is compulsory for major development, not a courtesy. Section 61Z of the Town and Country Planning Act 1990, inserted by the Planning (Wales) Act 2015, requires an applicant to carry out consultation before submitting an application for major development, and the Welsh development management procedure order sets a 28 day period and prescribes who must be consulted. The resulting pre application consultation report forms part of a valid application, so a defective process is a validation problem rather than a presentational one.

England has no equivalent duty. An English consultant working on a Welsh site for the first time usually discovers this about six weeks later than they would have liked.

Which applications trigger the duty

The duty attaches to major development as defined in Welsh regulations, which follows the familiar thresholds: ten or more dwellings, a site of half a hectare or more where the number of dwellings is not known, 1,000 m² or more of floorspace, or a site area of one hectare or more for other development.

Certain categories sit outside it, and Developments of National Significance follow their own separate regime with its own consultation requirements. Check the definition against the specific proposal rather than assuming, because a scheme that falls just under a threshold at concept stage often creeps over it during design.

The duty applies to the application, so a resubmission of a major scheme generally needs the exercise repeating unless the earlier consultation remains current and the proposal is materially the same. Take advice on that rather than relying on the previous report.

The 28 day period and who must be notified

The consultation must run for at least 28 days, and the clock starts when the required notices are given and the documents are made available.

Those to be notified include owners and occupiers of land adjoining the site, the community or town council for the area, the local planning authority itself, and the specialist consultees who would be consulted on the application if it were submitted. The specialist list is the one that trips people up, because it means identifying statutory consultees such as Natural Resources Wales, the highway authority and Dwr Cymru before the application exists.

A site notice is required, and it has to remain in place for the consultation period. Photograph it on the day it goes up, with something in the frame that dates it.

Address lists deserve care. Adjoining land means land that touches the site boundary, including land across a shared access and land behind a rear fence, and a list built from a sales plan rather than from the title plan will miss somebody. Where ownership is unclear, serve on the occupier as well.

Publishing the draft application documents

The applicant must make the proposed application documents available for inspection. In practice that means the draft plans, the draft Design and Access Statement and the supporting documents that would accompany the submission.

This is the part consultants find uncomfortable, because it publishes a scheme before it is finished. Plan for it. Documents released at consultation stage should be complete enough to consult on and stable enough that the submitted scheme is recognisably the same proposal.

Where the scheme changes materially after consultation, the authority may take the view that the consultation no longer relates to the application before it. Material change after consultation is the single biggest risk in the process, and it is a design management problem rather than a legal one.

Writing the pre application consultation report

The report submitted with the application has to demonstrate what was done and what came back. Structure it so an officer can verify compliance quickly.

1. The statutory basis and confirmation that the development is major.
2. Who was consulted, by what method, with dates and copies of the notices.
3. Where and how the documents were made available.
4. Every response received, reproduced or fairly summarised.
5. The applicant's response to each point, including changes made and changes rejected with reasons.

The fifth element carries the weight. A report that lists objections and then says the scheme is unchanged, with no reasoning, invites the authority and the community council to say the consultation was a formality.

Do not filter responses. Reproducing an objection you disagree with, and answering it, is far stronger than omitting it.

What happens if consultation is defective

If the report is missing or the process did not meet the statutory requirements, the authority can decline to validate. That is the common outcome and the least costly one, because it is discovered early.

The more difficult scenario is a defect discovered later, after validation, when an objector points out that a notice was not served or the period ran for 26 days rather than 28. The authority then has to decide whether the application was validly made, and the safest course is usually to repeat the consultation and resubmit.

Keep the evidence file as you go: dated photographs of the site notice, copies of every letter with the address list, screenshots of the published documents, and a log of responses. Assembling it afterwards from memory is how errors appear.

How this differs from voluntary pre application advice

Statutory consultation and pre application advice from the authority are separate things that happen at roughly the same time, and confusing them is common.

Run them in parallel, not in sequence. The authority's advice on policy and on the document schedule shapes what you consult on, and the consultation responses then shape the final Planning Statement.

Where community engagement is substantial, the material also feeds a Statement of Community Involvement, though in Wales the statutory report is the document that matters for validation.

Practical sequencing for a Welsh major application

Work backwards from the target submission date. Allow 28 days for the consultation itself, two weeks before it to prepare and serve notices and identify consultees, and three to four weeks afterwards to write the report and respond to what came in. That is roughly ten weeks of programme before the application is lodged.

And build in a contingency for a second round. If the responses show a genuine problem with the scheme, changing the design and re-consulting is better than submitting into a wall of objection with a report that cannot answer it.

PlanScope's drafting is grounded in English national policy and English local plans, so any Welsh submission needs the reviewer to substitute Planning Policy Wales, the relevant Technical Advice Notes and the Welsh procedural requirements before it goes in.
