What is EMF?

Electromagnetic fields — what they are, where they come from, and what a professional survey measures in your home.

The basics

What are electromagnetic fields?

EMF stands for electromagnetic fields. They are invisible areas of energy produced by electrically charged objects — and they are everywhere in the modern home. Your wifi router, your smart meter, your mobile phone, your wiring. All of it produces electromagnetic fields of varying frequencies and strengths.

The question isn't whether EMF exists in your home — it does. The question is how much, from what sources, and whether the levels you're exposed to during sleep are worth addressing.

Are all EMFs the same?

Non-ionising

From wifi, phones, power lines and wiring. This is what home surveys measure. Subject of ongoing health research.

Ionising

X-rays and gamma rays. Not produced by household devices. A completely separate category from home surveys.

What does a survey measure?

Electric fields

From wiring, appliances and electrical infrastructure in and around your property.

Magnetic fields

From power cables, transformers, fuse boxes and smart meters.

Radiofrequency radiation

From wifi routers, mobile networks, smart meters and DECT cordless phones.

Dirty electricity

High-frequency interference on the circuit from energy-saving devices and solar inverters.

Body voltage

The electrical potential induced in your body — most relevant in the bedroom.

What can be done?

Quite a lot — and most of it is practical and affordable. Repositioning a router. Replacing a cordless phone. Switching off wifi at night. The survey identifies the sources. The report prioritises the actions.

Key stat

90% of our time is spent indoors — yet most people have never had their home environment measured.
