5G mast planning permission and objections
A 5G mast can improve a poor mobile signal and still raise a fair question about its position or design. If one is proposed near your home or business, the useful starting point is to understand what the council is being asked to decide.
Many mobile network installations use permitted development rights. Some need an application to the council first, called prior approval, while others do not. This guide explains the difference, the objections that can carry weight, the health safeguards and what the move towards 6G may mean.
This guide covers England. The planning rules differ elsewhere in the UK. For the detailed legislation and equipment limits, see Class A of Part 16.
Need help with permitted development?
Permitted development can avoid a full planning application, but only if the right applies and every relevant limit and condition is met. Planning Geek can check the planning history, Article 4 directions and other restrictions, and help with a lawful development certificate or prior approval where needed.
Does a 5G mast need planning permission?
Development needs the relevant planning permission, but that permission does not always come from a full application. In England, Part 16 of the GPDO already grants permission for specified communications development, provided its limits and conditions are met.
For mobile network works, Class A normally applies to development by or on behalf of an electronic communications code operator for its network. It can cover masts, antennas, cabinets and associated equipment. It is not a general right for anyone to build a mast on land they own.
| Route | What it means |
|---|---|
| Permitted development without prior approval | The proposal satisfies the relevant limits and conditions and does not trigger the prior approval procedure; other notifications or consents may still be needed |
| Permitted development requiring prior approval | The operator must apply before starting so the council can address the specified siting and appearance matters |
| Full planning application | The proposal falls outside the relevant permitted development right, or the applicant seeks express permission; the decision has a wider planning remit |
The name “5G” does not decide the route. The equipment, operator, location, size and proposed works do. The same site may support more than one generation of mobile service.
What can the council decide at prior approval?
Keep three questions separate. First, does the development qualify under Class A? Second, does the proposal require prior approval? Third, are the matters reserved for that decision acceptable? Prior approval cannot make an ineligible proposal permitted development.
For a mast proposal requiring this procedure, the council considers siting and appearance. That means where the apparatus goes and how it will look in its surroundings. The decision is not a public vote on whether 5G should exist.
The August 2026 NPPF, policies CO1 and CO2 gives substantial weight to improved network coverage, capacity, reliability and resilience. It expects existing structures to be used, upgraded or replaced unless there is no reasonable opportunity, taking account of network needs. Appropriate siting, design and supporting evidence also matter. These policies must be applied within the scope of the actual planning decision.
Objections that can make a difference
You can support better coverage and still question a particular mast. Explain the specific effect of the plans, rather than relying on how strongly you feel about the technology.
| Issue | Useful evidence |
|---|---|
| Position, height and bulk | Identify the viewpoint, the surrounding building heights and the part of the mast or cabinets that causes the effect |
| Street or landscape character | Explain the relationship with the street, skyline, open landscape or a recognised landmark; use clear photographs |
| Heritage | Identify the listed building, conservation area or other heritage interest and explain the effect on its setting or character |
| Footway access and highway safety | Show the remaining pedestrian space, access to a property, a junction sightline or the effect on wheelchair and mobility scooter users |
| Trees and screening | Identify trees or roots affected by the layout, and whether promised screening is realistic and within the applicant’s control |
| Alternative siting or design | Suggest a specific position, shared structure, cabinet arrangement, colour or design change that could reduce the identified harm |
The wireless development code of practice discusses these practical issues, including cabinet placement, disabled access, junction visibility, trees and the appearance of masts. Class A also imposes conditions concerning footway obstruction and access. A legal failure of the right should be raised as such, separately from an objection to the design.
Noise, construction disturbance and other concerns need to be related to the particular proposal and the legal decision. Do not assume every issue that might matter on a full planning application is an unrestricted ground for refusing telecom prior approval.
Can you insist that the mast goes somewhere else?
You can question the alternatives evidence and propose a realistic improvement. For a new site, current national policy expects evidence that the use of existing buildings, masts or other structures has been explored. But the council does not have to refuse an acceptable site simply because someone can name another location.
A mast needs to work as part of a network. Terrain, surrounding buildings, the area needing service, power, connections to the wider network and maintenance access can rule out an apparently obvious alternative. Ask whether a specific option has been properly considered, rather than demanding an unlimited search.
Mast sharing can reduce the number of separate sites, but extra equipment may need a larger replacement structure. That trade-off should be assessed against the actual design and surroundings.
What will not establish a sound reason for refusal?
- A general objection to 5G or the existence of mobile networks
- The number of signatures on a petition, without relevant planning reasons
- A reduction in private property value, by itself
- An arbitrary distance from homes or schools that has no basis in the applicable controls
- A demand that the council prevent competition between mobile operators or adopt a different local exposure standard
Current national policy says councils should not question the need for network expansion or upgrading, require minimum separation distances or impose different health safeguarding standards. That still leaves room to scrutinise a particular location, design and the relevant supporting information. Government planning guidance distinguishes material planning considerations from purely private interests.
What about health concerns and 5G?
Health concerns deserve a clear answer. The planning system uses the public-exposure guidelines of the International Commission on Non-Ionizing Radiation Protection, usually shortened to ICNIRP, informed by UK Health Security Agency advice. Current national policy seeks evidence including a statement self-certifying that cumulative exposure will comply when the installation is operating.
The UKHSA advice on 5G reports that its measurements found exposures below the guideline levels, with measured 5G exposure generally lower than or similar to 4G exposure. Its base-station guidance explains the wider evidence and the controls used to prevent public access to areas close to powerful antennas.
This does not mean that a specific compliance query should be ignored. If the compliance material describes the wrong site or apparatus, omits relevant cumulative information, or contains a credible, specific error, identify that issue. A generic claim about radio technology does not demonstrate a failure to comply.
Ofcom publishes mobile base-station measurements and provides information about requesting measurements. Planning assessment and regulatory compliance are related safeguards, but they are not interchangeable procedures.
The deadline for comments is not 56 days
The normal telecom prior approval determination period is 56 days from receipt of an application meeting the statutory submission requirements. A longer period may be agreed in writing. That is the decision timetable, not an invitation for residents to wait 56 days before objecting.
Use the consultation deadline shown on the council’s application page or notice. Anyone can submit relevant comments, even if they did not receive a neighbour letter. Send the response to the council against the application reference. A social media post or a message sent only to the operator may never reach the planning file.
The applicant must receive the relevant written notification within the applicable statutory period. A committee vote alone is not enough. Saying only that prior approval is required is also insufficient if the council then fails to notify approval or refusal before the period expires. If it misses the necessary notification, the expiry provisions may allow qualifying development to proceed. They do not turn a mast outside the permitted development rules into a lawful proposal.
How to write a focused mast objection
- Read the plans, supporting statement, site location and application description, and confirm the planning route
- Identify whether your point concerns failure to qualify under Part 16, or a siting and appearance issue within prior approval
- Describe the specific effect and add a photograph, measurement or document reference where helpful
- Suggest a realistic change if one could resolve the problem
- Submit directly to the council before the advertised comment deadline and keep a copy
For example: “The cabinet position shown on drawing 02 would narrow the footway beside the existing crossing. Please assess the remaining usable width, including the door opening and the needs of wheelchair users, and consider moving the cabinet within the proposed site.” That gives the decision-maker a defined issue to check.
An objection need not be long. A precise, evidenced point is more useful than pages of general opposition. Planning Geek can assess the plans and help prepare a planning representation. Contact us with the application reference and site address.
What if there is already a mast?
A proposal may replace an existing mast, increase its height or width, add antennas or alter cabinets. These works have different limits and prior approval triggers. Some upgrades can proceed without an application for prior approval, so an absence from the consultation list is not proof of a breach.
Equally, “replacement” is not a blanket exemption. Compare the existing and proposed dimensions, the original permission and the site restrictions. Our Class A guide explains the ground mast, rooftop, width and equipment tests. Where an application concerns only specified alterations, it does not necessarily reopen the whole established installation.
If the installed work appears materially different from what was permitted, check the approved plans, any agreed amendments and whether subsequent alterations have their own permitted development right. A request to the council’s planning enforcement team should identify the apparent breach and evidence. Disliking a lawful mast is a different matter.
Is there an appeal, and what does it cost?
There is no council fee simply to submit a consultation comment. An operator or applicant pays any applicable application fee; see our planning application fees guide. Professional advice is a separate cost.
An applicant may be able to appeal a refusal. A resident objecting to an approval does not have the same ordinary planning appeal right. A complaint, an enforcement enquiry or a legal challenge may address different problems. Get prompt advice about the appropriate route. Planning Geek provides planning consultancy and can work with a suitable legal specialist where litigation advice is needed.
Will 6G need more masts?
6G is the next mobile generation under development, internationally known as IMT-2030. As at 18th September 2026, its standards process is still under way. ITU has reported agreement on draft technical performance requirements, with formal approval expected later in 2026. These requirements do not specify how many masts a particular town will need.
Coverage and capacity are different. Coverage concerns whether a usable signal reaches an area; capacity concerns how much traffic the network can handle at once. A busy town centre can show a signal on your phone and still need more equipment to serve everyone using it.
Frequency matters too. Higher frequency services can provide substantial capacity, but generally cover shorter distances and penetrate buildings less readily than lower frequency services. They may therefore use transmitters closer to users, alongside lower frequency coverage. The Government and Ofcom guide to 5G explains these differences. The labels 5G and 6G do not, on their own, determine mast spacing or height.
More apparatus does not always mean more tall masts. Small cells can use suitable buildings or street furniture. Existing sites may be shared or upgraded, sometimes with a larger replacement structure. The UK Wireless Infrastructure Strategy envisages existing and new frequency bands for 6G and records operators’ preference for a smooth transition, including software upgrades where possible. That is a preference, not a guarantee that every existing installation will be suitable.
The cautious expectation is a mixture of reuse, upgrades and some new installations, depending on spectrum, demand and local conditions. There is no settled universal requirement for a dense new grid of tall 6G masts.
Also, 6G is not the same as 6 GHz. One is a mobile generation; the other is a frequency band. Ofcom’s work on the 6 GHz band concerns spectrum access, not planning permission to erect a mast.
Does today’s planning law allow future 6G equipment?
Potentially, yes. Part 16 describes electronic communications operators, apparatus and development without making permission depend on a 5G or 6G label. Future equipment may qualify if it meets the rules in force when proposed, including any required prior approval.
That does not mean Parliament has already approved every future network design. Equipment outside the permitted development limits needs the appropriate alternative planning route. A proposed relaxation of the rules must be distinguished from an amendment that has actually become law.
Relevant legislation for 5G mast
The planning explanation above is based on the current English GPDO and the August 2026 NPPF. Check the Changes to Legislation information when using the statutory source. The wireless code remains useful guidance, but its references to older NPPF paragraph numbers should not be treated as current.
