EMF Survey Services

An EMF Survey is a thorough check of EMF levels within a survey property – which might be your existing home, or one you intend to buy or rent.
Electromagnetic fields (EMF) are a type of radiation, and there are two kinds of EMF that people are concerned about: low frequency and radio-frequency EMF.
Low frequency EMF arises from electrical power lines, substations, underground cables, house wiring and electrical appliances.
Radio-frequency EMF is emitted by all radio-transmitting equipment, including radio and TV transmitters, mobile phone masts and other cell sites, radar installations – and also from numerous wireless devices found within the home.
You can order a survey for either EMF type, but many of our clients want to include both types.
What does an EMF-surveyor do?
EMF hotspots in the home are often very localized, so they can affect one part of a house much more than another.
So the surveyor will take EMF measurements in each room of the property, concentrating especially on where people spend most of their time – 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.
Many of our surveys are conducted for people who are intending to buy a new property. They are often concerned about nearby external EMF sources such as electrical substations, power lines and mobile phone transmitters, but also about internal EMF sources inherent in the property, which may include smart meters, electric wiring and installed appliances.
If the survey is for the client’s current home, they will probably want to know about internal sources of EMF, as well as external. So we will take measurements with 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 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 you can take action on. It is a positive step towards reducing biological stress on your family from harmful radiation.
Ideally, your home should be a low-EMF zone, a refuge from the high EMF levels found everywhere today, in public and private places.
.
But this is not always possible or easy. You first need to know exactly where EMF levels are too high – and why – so that you can reduce the radiation (if this is possible) or take other steps to limit your exposure.
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, because 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 an EMF survey for a property you wish to sell, because it can reduce buyer uncertainty, increase confidence, and shorten the selling time.
Who should do your EMF survey?
For your own home, you could do it yourself – if you have suitable meters and are technically inclined. But an experienced, professional EMF surveyor may be better able to identify radiation sources and suggest how to deal with them.
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

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.
