THE GUIDE / rules
Polytunnel planning permission: prepare a council enquiry (UK)
Set out the exact site and proposal so the relevant planning authority can explain what process applies.
To check the planning position for a proposed polytunnel, prepare a dated description of the site, structure and intended use, then ask the relevant planning authority what process, if any, applies. This guide helps you write that enquiry. It does not interpret planning law or establish an exemption.
Research status: no official planning guidance or authority response has been verified for this draft. It contains no size threshold, exemption, permission rule or conclusion about any UK jurisdiction.
Identify the site and the authority
Write down the full site address or a clear location description, including the relevant plot or land parcel if known. Use the official council or government service for that location to identify the planning authority and its enquiry route. If more than one authority or land boundary might be relevant, describe the location and ask where the question should be sent rather than guessing.
Use the authority’s current contact channel and ask whether it offers an informal enquiry, written advice or a formal application route. Ask what status its reply has and whether a fee, form or additional information is required; record the answer before choosing a route.
Describe the actual proposal
Describe the proposal you are considering rather than asking only whether “a polytunnel” needs permission. Prepare a dated site sketch showing the proposed footprint, boundaries, nearby buildings and access routes. Include dimensions and height if known, the proposed position, the model or construction description, and how you intend to use it. Label estimates and say which details are not yet decided.
Attach the maker’s drawing or product description if you have one, along with any relevant site plan or photographs requested by the authority. The size guide can help turn a bed-and-path plan into a footprint, but a layout calculation does not establish whether a planning process applies.
If the land is rented, part of an allotment or managed by another body, keep questions about its terms and consent separate. The allotment guide covers what to ask the site body. An answer from a landlord or allotment manager does not itself answer the public planning enquiry.
Ask a narrow, answerable question
Ask the authority to assess the proposal as described and to identify the process it considers relevant. Include these questions in the enquiry:
- Does the information identify the correct authority and site, or should the enquiry go elsewhere?
- Based on the attached description, what planning process or application route should I follow before proceeding?
- Which facts about the site, intended use or proposed structure affect that answer?
- What drawing, measurements, documents or application details do you need to give a site-specific response?
- Does the authority recommend a formal application or another written determination for this proposal?
- What is the scope and status of the response, and what changes to the proposal would require a fresh enquiry?
If the proposal changes, send the revised details and ask whether the earlier reply still addresses it.
Keep the enquiry and answer together
Keep the submission and answer together, with a short record of what each document covers.
| Record | Details to keep |
|---|---|
| Submission | Description, dated attachments, date sent and reference number |
| Response | Complete reply and its stated scope and status |
| Proposal covered | Exact version, position, dimensions and use addressed |
| Qualifications | Unanswered questions or conditions stated in the reply |
| Guidance supplied | Copy or link, with the date you checked it |
Use the authority’s description of its response. Do not label an informal reply as a formal decision yourself.
Do not turn a short reply about one described site into a general rule for other locations or proposals. If the answer is unclear, ask the authority to clarify its scope and what step, if any, it expects next. Where you need to make a formal application, follow the authority’s current published process and instructions.
