Rural broadband and telecoms masts under Part 16

A telecoms mast in open countryside is usually not a planning application at all. Part 16 of Schedule 2 to the General Permitted Development Order 2015 grants permitted development rights to electronic communications code operators, and for most new masts the only planning process is an application for prior approval of siting and appearance. That is a narrow test. The authority cannot refuse because the mast is unnecessary, because a different operator already covers the area, or because residents are worried about radio emissions.

For a landowner, the more consequential negotiation is not the planning one. It is the code agreement, and that is governed by telecommunications legislation rather than by the planning system.

The rights code operators hold

Part 16 permits code operators to install, alter or replace electronic communications apparatus, to use land for a mast or apparatus, and to carry out development ancillary to radio equipment housing. The rights are conditional, and the conditions cover height, position relative to highways and protected land, the number of masts on a site, and reinstatement when apparatus is removed.

Separately, the electronic communications code in the Communications Act 2003, as amended by the Product Security and Telecommunications Infrastructure Act 2022, gives operators rights to install and keep apparatus on private land by agreement, and to apply to the tribunal for those rights where agreement cannot be reached. Consideration under the code is assessed on a basis that disregards the value of the site for telecoms use, which is why rents offered under the modern code are lower than landowners expect from older agreements.

Those two regimes answer different questions. Permitted development rights decide whether planning permission is needed. The code decides whether the operator can occupy your land and on what terms. Neither is a defence to the other.

Height limits and what the 2022 changes did

The height ceilings in Part 16 are stated in the Order itself and they have changed more than once, most recently in 2022 when the limits for new ground-based masts were raised and operators were given greater scope to strengthen and heighten existing masts without a fresh prior approval.

Because those figures have moved twice in recent years, read the current consolidated text of Part 16 on the legislation website rather than a secondary summary. A guide written against the pre-2022 limits will give the wrong answer, and so will a memory of the position before that.

The structural points are stable even when the numbers are not. Ceilings are lower on protected land than elsewhere. Sharing an existing mast is treated more permissively than building a new one, which is deliberate policy. And ground-based apparatus other than the mast itself, including equipment cabinets and generators, has its own limits on volume and position.

Where a mast approaches a height at which aviation safeguarding is engaged, consult the Civil Aviation Authority position and any aerodrome safeguarding map for the area, because that constraint sits outside Part 16 entirely.

Prior approval of siting and appearance

For development where prior approval is required, the operator applies to the local planning authority with details of the proposed development, and the authority considers only the siting and the appearance of the apparatus.

The determination period for mast prior approvals is 56 days. If the authority has not notified its decision within that period, the development may proceed in accordance with the application, so the deadline is real and operators track it carefully.

What the authority can properly consider within siting and appearance is wider than it first looks. The choice between two positions on a field, the colour and finish of the structure, the design of the cabinet compound, screening and planting, the type of mast, and the visual effect on a designated area are all siting or appearance matters. What it cannot consider is the need for the development, coverage economics, or health effects beyond confirming that the standard emissions declaration has been provided.

That declaration is the confirmation that the equipment will operate within the international exposure guidelines applied in the United Kingdom. National guidance is clear that it is not for the local planning authority to set its own health safeguards, and refusals on that ground do not survive appeal. Where a scheme needs it, a Telecommunications Compliance statement is the document that records the declaration and the technical justification for the chosen site.

Protected land and the tighter position

Article 2(3) land, which includes conservation areas, National Parks, National Landscapes, World Heritage Sites and the Broads, carries lower height ceilings and, in places, narrower rights. Sites of special scientific interest are treated separately again, with restrictions on what may be installed.

The consequence in practice is that a mast proposal in a National Landscape is more likely to need prior approval, more likely to attract a landscape objection, and more likely to be refused on appearance. Operators respond by proposing slimmer monopoles, matt finishes, positions against woodland edges rather than on skylines, and compounds screened with native hedging.

Fixed-line broadband infrastructure sits in a different part of the story. Cabinets and above-ground boxes serving fixed connections have been treated more permissively, including in protected areas, on the basis that rural connectivity outweighs the visual effect of a cabinet. That policy choice is explicit rather than accidental, and objecting to a cabinet on appearance grounds alone rarely succeeds.

Notice and consultation

Operators must give notice of proposed development, and the requirements differ with the type of apparatus. Site notices, notification of owners and occupiers, and notification of the authority are the usual mechanisms, and there are specific expectations where apparatus is proposed near a school or college.

Beyond the statutory minimum, operators work to a non-statutory code of practice on mobile network development which sets expectations for pre-application engagement with communities and with authorities. It is not enforceable through the planning system, and authorities do use compliance with it as a marker of whether an operator has engaged properly.

For a parish council, the practical step is to ask the operator for its site selection analysis: the coverage requirement, the search area, the alternative sites considered and why each was discounted. That document is the basis of any credible argument that a different siting would work.

Landscape and heritage effects

On an open ridge or beside a listed farmstead, the visual case is the whole case.

A proportionate assessment identifies the receptors, uses accurate visual representations from agreed viewpoints, and considers the cumulative effect with existing masts and overhead lines. On a prominent site in a designated landscape, a Landscape and Visual Impact Assessment prepared to the recognised guidelines carries far more weight than a photomontage with no stated method.

Where the setting of a listed building, a scheduled monument or a registered park is affected, the statutory duties on the decision maker apply and a Heritage Statement assessing the effect on significance should accompany the application. Setting is where masts most often cause heritage harm, because the structure is visible from a long distance and the mitigation options are limited.

Responding as a landowner or a neighbour

If you are being approached to host apparatus, take advice before signing. The agreement will run for years, the code restricts your ability to remove the operator, and the terms on access, upgrading, sharing and termination matter more than the annual figure. Ask specifically about rights to share the mast with other operators, about who is responsible for reinstatement, and about access routes across the rest of the holding.

If you are objecting, write to siting and appearance and nothing else.

1. Identify a specific alternative position and explain why it delivers the same coverage with less effect.
2. Address the visual effect from named public viewpoints, with distances.
3. Raise the design of the structure and the compound: height, profile, colour, fencing, screening.
4. Point to designations and the duties they create.
5. Do not argue need, competition or health, because those points will be set aside and they weaken the rest.

Submit within the consultation window. With a 56 day clock running, a late objection may arrive after the decision.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
