Selling a House Near a Phone Mast: Does It Affect Value?

Phone masts are a common feature of the UK landscape, with over 52,000 mobile base stations across the country according to Ofcom. As 5G rollout accelerates, more masts are being installed in residential areas, and sellers are increasingly asking whether a nearby mast will affect their sale. The short answer is: it depends on how visible the mast is, how close it is, and how your buyer perceives it.

This guide covers what the evidence says about phone masts and property value, what you need to disclose when selling, how the planning system works for mast installations, and practical strategies for addressing buyer concerns.

Does a phone mast actually affect property value?

The question of whether phone masts reduce property values has been studied extensively, but the evidence is more nuanced than many sellers expect.

What the research says

RICS (Royal Institution of Chartered Surveyors) has examined the relationship between telecommunications infrastructure and property values. Their research indicates that the impact varies significantly depending on the circumstances:

• Highly visible masts within 200 metres of a property can reduce its value by approximately 5% to 15%. The greatest impact occurs when the mast is directly visible from the property's main living areas or garden.
• Masts beyond 200 to 300 metres typically have little or no measurable effect on value, particularly if they are screened by buildings, trees, or topography.
• Masts that are not visible from the property, even if relatively close, tend to have minimal impact because buyers are often unaware of them.

A study by the University of Oxford found that properties within sight of a phone mast sold for approximately 7% less than comparable properties without a visible mast, though this figure varied considerably by location and mast type.

Perception versus reality

The effect of a phone mast on value is driven largely by buyer perception rather than any measurable harm. Buyers who are concerned about health effects or visual amenity may offer less or decline to purchase altogether, while other buyers may not be concerned at all. The practical result is that a nearby mast can narrow your buyer pool, which in turn can affect the price you achieve.

This is similar to other factors that influence buyer perception without necessarily affecting the property itself, such as proximity to electricity pylons, railway lines, or busy roads. For more on how external factors affect pricing strategy, see our guide on pricing your house to sell.

Health concerns: what does the science say?

Health concerns are the primary reason buyers worry about phone masts. Understanding the official scientific position will help you respond to questions confidently and factually.

The official UK position

The UK Health Security Agency (UKHSA), which took over the responsibilities of Public Health England, has consistently stated that there is no convincing evidence that exposure to radio frequency electromagnetic fields (RF EMF) from phone masts, at levels below the guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), causes adverse health effects.

The World Health Organisation (WHO) holds a similar position. Its fact sheet on electromagnetic fields and public health (updated 2024) states that, based on the weight of evidence reviewed, exposure to low-level RF EMF does not cause any known health consequences.

ICNIRP guidelines and compliance

All phone masts in the UK must comply with the ICNIRP exposure guidelines. These guidelines set limits on the intensity of radio frequency emissions that the public can be exposed to. Before any mast is installed, the operator must provide an ICNIRP compliance certificate to the local planning authority, confirming that emissions will be within the permitted limits.

Ofcom carries out regular audits of mobile base stations to check compliance. Their measurements consistently show that actual emissions from phone masts are a small fraction of the ICNIRP limits — typically hundreds or even thousands of times below the maximum permitted level.

While these facts will not persuade every buyer, being able to reference the official positions of UKHSA, WHO, and ICNIRP gives you a credible basis for addressing health-related questions.

What you need to disclose when selling

Sellers in England and Wales have a duty not to misrepresent the property. Understanding what you must disclose about a nearby phone mast is important to avoid problems during and after the sale.

The TA6 Property Information Form

The property information form does not contain a specific question about phone masts or telecommunications infrastructure. However, several sections are potentially relevant:

• Section 7 (Environmental matters). The environmental section of the TA6 asks whether you are aware of any environmental issues that might affect the property. While a phone mast is not an environmental hazard in the traditional sense (contaminated land, flooding), some solicitors advise disclosing a prominently visible mast here to avoid any allegation of concealment.
• Section 6 (Planning). If a mast has been installed recently near your property, or if you are aware of a pending application or prior approval notice for a new mast, this is relevant to the planning section.

Direct questions from buyers

If a buyer or their solicitor asks you directly whether there is a phone mast near the property, you must answer truthfully. Under the principle established in Sykes v Taylor-Rose [2004], sellers are not generally required to volunteer information that has not been asked for. However, the Consumer Protection from Unfair Trading Regulations 2008 prohibit misleading omissions in commercial transactions, and the Property Ombudsman's code requires estate agents to disclose material information.

The safest approach is straightforward honesty. If there is a phone mast that is visible from or very close to the property, assume the buyer will discover it during viewings, in their survey, or through their own research. Attempting to conceal it is more likely to cause the sale to fall through than addressing it openly. For a full overview of your disclosure obligations, see our guide on what to disclose when selling a property.

How phone masts get planning permission

Understanding how phone masts are authorised helps sellers answer buyer questions and anticipate concerns about future installations.

Permitted development rights

The majority of phone masts in England are installed under permitted development rights granted by Part 16 of the Town and Country Planning (General Permitted Development) (England) Order 2015. This means the operator does not need to apply for full planning permission, but must follow a prior approval process for siting and appearance.

Under the prior approval process:

• The operator submits an application to the local planning authority with details of the proposed mast, including its height, design, and siting.
• The operator must include an ICNIRP compliance certificate.
• The local authority typically consults neighbours within a defined radius, giving them an opportunity to comment.
• The authority can only refuse prior approval on grounds of siting and appearance. It cannot refuse on health grounds, provided the ICNIRP certificate has been submitted.

When full planning permission is required

Full planning permission is required for:

• Ground-based masts exceeding 25 metres in height (or 20 metres in some locations)
• Masts in conservation areas, Areas of Outstanding Natural Beauty, National Parks, or the Broads
• Installations on or near listed buildings
• Masts that fall outside the scope of permitted development rights

When full planning permission is required, the application follows the standard planning process with full public consultation. Objections can be raised on a wider range of grounds, though health concerns are still given limited weight provided the installation meets ICNIRP guidelines. For more on how planning matters relate to property sales, see our guide on conveyancing enquiries.

Will a surveyor flag a nearby phone mast?

Whether a phone mast appears in a property survey depends on the type of survey and the mast's prominence.

A RICS surveyor conducting a Level 2 (HomeBuyer Report) or Level 3 (Building Survey) may note the presence of a visible phone mast in their report, particularly if it is very close to the property or could affect its market value. However:

• Surveyors are not required to carry out specific checks for telecommunications infrastructure as part of a standard residential survey.
• A mortgage valuation (Level 1) is a brief inspection and is unlikely to mention a phone mast unless it is exceptionally close or directly on an adjacent plot.
• If the surveyor does note a mast, they may comment on its potential effect on value and saleability in their market commentary section.

Buyers who are particularly concerned about phone masts can check the Ofcom Sitefinder tool or the MAST Data website, which shows the locations of all UK mobile base stations. This information is publicly available, so you should assume that a diligent buyer will be aware of any mast in the vicinity.

How distance and visibility affect the impact

Not all phone mast situations are equal. The following table summarises how distance and visibility typically influence the effect on property value and buyer behaviour:

The key factor is visual prominence. A mast that dominates the view from the property's main rooms or garden will have a greater impact than one that is technically closer but hidden behind buildings. This is consistent with how other visual detractors (pylons, substations, commercial buildings) are treated by valuers.

How to address buyer concerns

If your property is near a visible phone mast, proactive management of buyer concerns is far more effective than hoping nobody notices. Here are practical steps you can take:

1. Be upfront with your estate agent. Make sure your agent is aware of the mast and can address questions confidently. An agent who is caught off guard by a buyer's question will handle it less well than one who is prepared.
2. Have the facts ready. Prepare a brief summary of the official health position (UKHSA, WHO, ICNIRP) and the regulatory compliance requirements. You do not need to be defensive — simply having accurate information available demonstrates transparency.
3. Emphasise connectivity benefits. Proximity to a phone mast typically means excellent mobile signal and data speeds. For buyers who work from home or rely heavily on their mobile connection, this can be a genuine advantage. Highlight signal strength during viewings if appropriate.
4. Consider landscaping. If the mast is visible from your garden, strategic planting of evergreen trees or hedging can reduce its visual impact. This is a relatively low-cost improvement that may reduce buyer objections.
5. Price realistically from the outset. If you believe the mast may affect what buyers are willing to pay, pricing correctly from the start is better than listing high and reducing later. A property that sits on the market with repeated price reductions attracts more suspicion than one priced fairly from day one. See our guide on pricing your house to sell for more detail.
6. Target the right buyers. Not every buyer will be concerned about a phone mast. Younger buyers and those working in technology may be less likely to object and more likely to value the connectivity benefits. Your estate agent can help you target marketing accordingly.

5G masts and the current rollout

The rollout of 5G across the UK is increasing the number of small cells and masts in residential areas. This has generated fresh concerns among some homeowners, but the situation is broadly the same as with earlier generations of mobile technology:

• 5G masts are often smaller than traditional masts. Many 5G installations use small cells mounted on existing street furniture (lamp posts, building facades) rather than large standalone towers.
• The same ICNIRP guidelines apply. 5G equipment must comply with the same exposure limits as 3G and 4G installations. UKHSA has confirmed that 5G does not pose a greater health risk than existing technologies.
• Permitted development rules have been updated to facilitate 5G deployment. The Electronic Communications Code (amended by the Product Security and Telecommunications Infrastructure Act 2022) gives operators broader rights to install equipment, though prior approval requirements still apply.

If a 5G mast has recently been installed near your property, or if you are aware of plans for one, this may come up during the conveyancing process. Being prepared with factual information will help your solicitor respond to any enquiries efficiently. See our guide on conveyancing enquiries for more on how these are handled.

Can a phone mast affect mortgage approval?

This is a common worry for sellers, but in practice phone masts rarely prevent mortgage approval. The main points to understand are:

• Most UK mortgage lenders do not have specific policies about phone masts. Their primary concern is that the property is adequate security for the loan, which is assessed through the mortgage valuation.
• The mortgage valuer may note a visible mast and adjust the valuation figure slightly if they believe it affects market value. This could reduce the amount the lender is willing to lend if the adjusted value changes the loan-to-value ratio.
• Outright refusals to lend due to a nearby phone mast are extremely rare. They are more likely to occur where a mast is physically on the property itself (for example, on a roof or in the garden under a wayleave agreement) rather than on a neighbouring site.

If you have a phone mast on your property under a wayleave or lease agreement, this is a different situation that you must disclose in full on the TA6. The agreement will be registered against the title and the buyer's solicitor will examine its terms carefully.

Mast removal and relocation: is it possible?

Some sellers ask whether a phone mast can be removed or relocated before they sell. In almost all cases, the answer is no:

• If the mast has planning permission or prior approval, the operator has a legal right to keep it in place for the duration of that permission.
• Under the Electronic Communications Code (revised in 2017), operators have strong statutory rights to install and maintain equipment, and landowners have limited ability to require removal.
• Requesting that an operator move a mast that is on third-party land (such as a council-owned site or a neighbouring property) is not something you as a neighbouring homeowner can typically achieve.

Rather than pursuing removal, most sellers are better served by focusing on the practical steps outlined above: pricing correctly, being transparent, and emphasising the property's other strengths.

The TA6 and environmental enquiries

During the conveyancing process, the buyer's solicitor will review your TA6 environmental section responses and may raise additional enquiries about the phone mast. Common questions include:

• When the mast was installed and under what planning authority
• Whether the operator has applied for any modifications or upgrades
• Whether the seller has received any rent or compensation related to the mast (relevant if the mast is on or very near the property)
• Whether there have been any complaints from residents about the mast

Answer these enquiries fully and honestly. If you do not know the answer to a question, say so rather than guessing. Your solicitor can help you obtain information from the local planning authority if needed.
