Electromagnetic Surveys
If you are considering purchasing a home close to an Electrical Substation or Pylon, our Site-Survey provides electromagnetic mapping – direct onto frequency charts. Therefore, providing conclusive evidence on the safety of the location.
For this type of bio-electromagnetic survey, we test the property against the SAGE biological safety standard (the latest and most trusted source for what constitutes as safe levels for humans, especially children) and electronically data-file the following:
1) “X” 50 Hz (first field axis)
2) “Y” 50 Hz (second field axis)
3) “Z” 50 Hz (third field axis)
4) “ALL 3D” (all the above together)
5) First Harmonic (double the field 100 Hz)
6) Second Harmonic (triple the field 150 Hz)
All our findings are supported by the real-time data-charts (as seen below) which form part of our “electronically witnessed” written assessment. No other UK company has testing expertise to this standard.
Electromagnetic Surveys provide a clear breakdown of all the magnetic flux density values radiating from the electrical distribution system. These levels are clearly evaluated against the biological health guidelines for prudent electromagnetic safety
Our clients will always have the opportunity to liaise directly with the site engineer; ensuring complete clarification of the reports and spectrum calculus.


What our customers say
Mrs Kirk-Cage
I am currently purchasing a property near a substation and was concerned about any health risks associated with it. Although I work in a school and there are sometimes substations located nearby. Alex came and tested inside the property and around the garden and location of the substation. I received a report within 2 days (on a weekend). It was extremely detailed and concise. I still had a few questions and on he Monday Alex called me to put my mind at ease. I would HIGHLY recommend the company without reservation.
Clare Haskins
Found this company from a simple Google search but from the first interaction, they were highly impressive; Professional, detailed and flexible but also warm, very supportive and easy to talk to (especially as a novice!). A first class customer experience with real value-add output - we cannot recommend EMF Detection highly enough, great value for money and send thanks to Alex and the team for a superb customer experience.
Rhys Turner
Thank you for providing all that information about pylons (can’t stop seeing them everywhere now ha)
The report is very detailed and the service on a whole was great.
Many thanks
Alana Crabtree
Great communication throughout. Provided a lot of information in response to my many, many questions (sorry again)
Will 100% recommend if/when anyone asks for an EMF survey.
Sharon Rogers
Alex was very informative and the report gave us clarity on whether or not the pylons we were previously concerned about were harmful or not.
Definitely recommend! Thank you
Robert Chekowski
Alex was very professional, very knowledgeable. We had plenty of questions and alex was always available to speak to.
Well ran business
Gillian Horsham
Thank you for your help Harvey. Your engineer was really informative and we got the report the same day as the survey. Brilliant service!
