Appealing a refused telecommunications prior approval
A refusal of prior approval for a mast can only rest on siting and appearance. Here is what the appeal has to prove, how the 56-day determination period works, and which refusal reasons fall outside the permitted scope.
A telecoms prior approval refusal is a narrow decision, and that narrowness is the operator's best asset on appeal. Under Schedule 2 Part 16 of the Town and Country Planning (General Permitted Development) (England) Order 2015, where prior approval is needed for a mast or ground-based apparatus, the local planning authority may consider only the siting and appearance of the development. Not the need for the network. Not the health effects. So an appeal against a telecoms prior approval refusal succeeds or fails on whether this piece of equipment, in this position, looks acceptable in this setting.
That also means a refusal notice straying into other territory repays close reading before you draft the statement of case.
What the authority is allowed to consider
Part 16 grants permitted development rights to electronic communications code operators, subject to limits on height, dimensions and location, and subject to conditions. Some of that development may proceed outright. Some of it requires the operator to apply to the authority for a determination as to whether its prior approval of siting and appearance is required.
The limits were widened by amendments to the Order in 2022, which raised the permitted heights for new and strengthened masts and changed what may be done on protected land. Check the current consolidated text rather than an older summary, because the figures and the Article 2(3) land distinctions have both moved.
The point to hold onto is the scope. Siting means where the apparatus sits, including its position within a site and its relationship to buildings, trees and the highway. Appearance means what it looks like: height, bulk, colour finish, the number of antennas and the cabinet arrangement. An authority that refuses because residents are worried about emissions, or because it would prefer a different operator's site, has refused on something it was not entitled to weigh.
Siting and appearance in practice
Inspectors deciding these appeals tend to work through a short sequence. What is the receiving environment, how prominent would the apparatus be from the places people actually experience, and could a modest move or a reduction remove the harm.
Prominence is assessed from public vantage points rather than from inside a single objector's bedroom window. A 20 metre monopole beside a mature treeline in a commercial yard reads differently from the same pole on a grass verge in a 1930s suburb, and the appeal turns on that reading. Verified photomontages from agreed viewpoints carry far more weight than an annotated site photo.
Where the setting is sensitive, the townscape case needs to be made properly. On a scheme in or close to a conservation area a Townscape and Visual Impact Assessment gives the inspector a structured account of effect by viewpoint, and the statutory duty on the authority is the same one examined in our note on heritage harm refusals and the statutory balance.
Health and the exposure certificate
National policy is unusually direct on this. Authorities should not question the need for an electronic communications system, and they should not set health safeguards of their own where the operator has provided a declaration that the installation conforms with the International Commission on Non-Ionizing Radiation Protection public exposure guidelines.
The declaration is a condition of the Part 16 right, so it belongs in the application rather than in the appeal. Supply it, state the guideline version, and move on. If the refusal reason cites public health concern, say in the statement of case that the matter sits outside the permitted scope of consideration and point to the declaration already on file.
The compliance paperwork for a site is a specialist exercise. A Telecommunications Compliance report is the usual vehicle for it, and councils expect a suitably qualified author: in practice a radio frequency engineer. Professional review of any draft is strongly advised before it is submitted.
The 56-day clock and deemed approval
Part 16 runs on its own timetable, and operators lose rights by missing it more often than they lose appeals. Where prior approval is required, development may begin if the authority has not given notice of its determination within 56 days of receiving the application. That is a shorter fuse than the eight weeks most minor applications run to, and it is calculated from receipt.
Three practical consequences:
- Date-stamp the submission and the acknowledgement, because the 56 days is evidential if the authority later disputes when it received a complete application.
- Do not agree an extension of time casually. It surrenders the deemed approval route for the sake of goodwill that may not materialise.
- If a determination arrives on day 60, take advice before relying on the lapse. Whether the clock ran at all depends on whether the application was valid when submitted.
Alternative site evidence that carries weight
Operators often lose on appeal because the site selection story is asserted rather than shown. An inspector weighing siting wants to know what else was examined and why it was discounted.
| Evidence | What it should show |
|---|---|
| Search area plan | The cell the site has to serve, drawn and explained |
| Candidate list | Each site considered, with the date and the reason for rejection |
| Site sharing enquiries | Which existing structures were approached and the outcome |
| Landlord position | Where a technically suitable site was refused by its owner |
| Coverage comparison | Why a lower or more distant mast does not deliver the service |
Negative answers from landowners matter. An inspector can accept that a less prominent site was unavailable, but only if the attempt is documented. A single sentence saying no alternatives were available invites the opposite conclusion.
Design, screening and the options short of refusal
Most of these appeals have an obvious middle ground, and the operator who has already explored it arrives in a stronger position. Reducing height by two or three metres. Moving the pole behind an existing building line. Switching to a slimline shroud or a wrapped cabinet finish. Relocating cabinets to the rear of a compound and screening them with close-boarded fencing rather than mesh. Painting to a recessive grey or green chosen against the actual backdrop instead of a default.
Where the authority has suggested a specific change, respond to it on the drawings before the appeal is lodged. Inspectors notice when an operator has absorbed a fair criticism, and they notice when it has been ignored.
Route, timescale and prospects
An appeal against refusal of prior approval goes to the Planning Inspectorate under section 78 of the Town and Country Planning Act 1990, almost always by written representations. The deadline for lodging is set by the procedure rules and is stated on the decision notice, so work from the notice rather than from memory of the general six month period.
On prospects, be realistic about what the record can tell you. Previous decisions are indicative of how inspectors have approached siting and appearance in comparable settings, never binding precedent, and the method for using them properly is set out in our guide to using appeal decisions in a planning application. A refusal resting on health concern or network need is vulnerable. A refusal resting on a well-evidenced townscape objection to a prominent pole in an otherwise unspoilt street scene is not. The same analysis applies to the separate question of a prior approval refusal under Class MA, where the permitted scope of consideration is wider and the appeal looks quite different.
And if the siting really is the weak point, a fresh application on a better position beats eight months at appeal.

Frequently asked questions
What can a council consider on a Part 16 prior approval application?
Only the siting and appearance of the proposed apparatus. The General Permitted Development Order limits the determination to those two matters, so the need for the network, the choice of operator and public health concerns all sit outside it. A refusal reason based on anything else is the first thing to challenge in a statement of case.
How long does a council have to determine a telecoms prior approval?
Fifty-six days from receipt of the application. If the authority has not given notice of its determination within that period, the development may begin under the terms of Part 16. The period runs from receipt rather than from validation, so keep the submission and acknowledgement dates on file in case the start point is later disputed.
Can neighbours object on health grounds?
They can write in, but national policy tells authorities not to set their own health safeguards where the operator has supplied a declaration of conformity with the ICNIRP public exposure guidelines. Objections on emissions therefore carry no weight in the decision. Supplying the declaration with the application, naming the guideline version, closes the point early.
What alternative site evidence does an inspector expect?
A search area plan showing the cell to be served, a list of candidate sites with dates and reasons for rejection, records of site sharing enquiries on existing structures, and evidence where a landowner refused. Documented negative answers are persuasive. An unsupported statement that no alternatives existed tends to be read as no search having taken place.
Is it faster to appeal or to resubmit on a different position?
A written representations appeal on a minor telecoms refusal commonly takes several months, and a fresh prior approval application runs on a 56-day clock. Where the authority's siting criticism is reasonable and a better position exists, resubmission is usually quicker and costs less. Appeal where the refusal reason falls outside siting and appearance, or where no better position exists.
