EMF Survey Services

House Survey

An EMF Survey is a thorough check of EMF levels within the survey property, which could be your existing home, or one you intend to buy or rent.

Electromagnetic fields (EMF) are a type of radiation. There are two kinds of EMF commonly found in the home: low frequency and radio-frequency EMF.

Low frequency EMF comes from from electrical power lines, substations, underground cables, house wiring and electrical appliances.

Radio-frequency EMF is emitted from many external sources. including radio and TV transmitters, mobile phone masts, other cell sites and radar installations. There are also many wired and wireless radio-transmitters in the home.

You can order a survey for low frequency EMF, radio-frequency EMF, or for both types.

What does an EMF-survey include?

EMF hotspots in the home are often very localized, so they can affect one part of a house much more than another. 

The surveyor will take EMF measurements in each room of the property. He will concentrate especially on areas where people spend most of their time. This includes bedrooms, sitting rooms, kitchens, dining rooms, and children’s play areas. We also include relevant outdoor areas.


An EMF survey can take up to an hour on site for a medium-sized (3-4 bed) house.

We record all EMF measurements and include them in our EMF Survey Report. The report also includes our evaluation of any EMF health risks, and our recommendations for reducing EMF exposure.

Who Needs an EMF Survey?

Many of our surveys are conducted for people who want to buy a particular property. They may have noticed an external EMF source near the property, for example an electrical substation, power lines / pylons, or a mobile phone mast. Sometimes they may be concerned about internal EMF sources, for example smart meters, electric wiring or installed appliances.

Other clients may want their current home assessed for EMF health risks. They may be concerned about their health, or that of other family members. Or they may suspect that high EMF levels already contribute to their health problems.

Property sellers may also consider an EMF survey. If there is a nearby substation or mobile phone mast, a professional EMF survey may help to reassure potential buyers.

Survey Purpose May Affect the Procedure

EMF Vulnerable

If the survey is for the client’s current home, they will probably want to know about internal and external sources of EMF. So we may take measurements with certain radio-frequency transmitting devices switched on, and then switched off, to get a full picture of internal and external radiation sources.

If we are surveying a property on behalf of a buyer, we will normally request that all non-installed radio-frequency transmitting devices (such as mobile phones, wi-fi or cordless phones) be switched off, to allow us to concentrate on external sources.


Why order an EMF survey?

High EMF levels are associated with many undesirable health effects. Increasingly, people are becoming aware of these EMF health issues.

The main advantage of an EMF survey is that it gives you dependable information. This includes the locations where EMF levels are high, and why. You can then take appropriate action to reduce your (or your family’s) exposure.

Of course you want your home to be a safe place. So it should be a low-EMF zone, and give you a break from the high EMF levels found almost everywhere.

When to order an EMF Survey

For the sake of your health, and your family’s, it is important to spend most of your time in places where EMF levels are low. Health effects from EMF exposure are cumulative. So if you have reason to be concerned about EMF levels inside your home, an EMF survey can be very empowering.

And if you are buying a property, in all the excitement it is easy to overlook serious environmental issues.

So a really good time to order an EMF survey is when you are intending to buy a new home – preferably before you commit to the contract.

There are also strong reasons for ordering a professional EMF survey for a property you wish to sell. It can reduce buyer uncertainty, increase confidence, and shorten the selling time.

Who should do your EMF survey?

There is no professional qualification or body which regulates electromagnetic radiation surveyors. So you will want to be confident that the person you choose is up to the job. Experience is the best teacher – so if you can, find someone who has done more than just a few.

EMF Survey Report

Most of our clients require a written EMF Survey report. Often this is because they want to use the report and its conclusions to help them with an important decision, for example a property purchase.


Our report will show all recorded radiation measurements, and indicate a level of concern for each one.  These measurements serve as a useful record of the survey findings, and make future comparisons possible.

Where EMF levels are high enough to represent a health hazard, we are often able to recommend action to reduce exposure. On the other hand, where we find low EMF levels, we can reassure our clients and give them peace of mind.

We email the survey report to our client, usually on the day after inspection.

We also answer any questions arising out of the survey or the report, until the client is satisfied.

Common EMF Survey Findings

Bedroom EMF

Quite frequently, we find elevated radiation levels in some parts of the home.

Sometimes these hotspots can be eliminated by switching off appliances or electronic devices – at least at night when they are not in use.

Where radio-frequency radiation enters from outside (for example from a mobile phone mast) it may be possible to screen certain windows with special net curtain material, or window film, to reduce the EMF penetration.

Radio-frequency sources inside the house can sometimes be re-positioned or partially screened to reduce radiation to more acceptable levels.

Low-frequency radiation can’t be screened, but it is still helpful to know about it, and how far it extends from the source – so that exposure can be minimised.
