EMF & RADIATION TESTING · LONDON

Honest testing
for London homes.

We started Atmos because we believed London homeowners deserved a straightforward, credible answer to a genuinely confusing question — what’s actually in my home’s atmosphere, and should I be worried?

Why we built Atmos.

The market for EMF and radiation testing in London was — and largely still is — a confusing mix of alarmism, pseudoscience and dated services with no clear brand or voice. On one side, operators happy to amplify anxiety to drive bookings. On the other, dismissal of all concerns as unfounded. Neither felt honest.

We wanted to do something different. Measure properly. Explain clearly. Leave the judgement to the homeowner.

Atmos was built around a simple idea — that people asking questions about their home environment deserve real answers, not alarm and not dismissal. We test with calibrated, professional-grade equipment. We write reports that anyone can understand. And we never exaggerate a result to justify a return visit.

BEFORE YOU BOOK
Four things we never compromise on.

Fully insured

We tell you what the readings mean — whether that’s reassuring or not. We don’t soften results to keep customers happy, and we don’t exaggerate them to justify further work.

Calibrated equipment

Professional-grade, calibrated instruments on every inspection — the same standard used by environmental consultants.

No obligation to book

Have questions first? Just get in touch. We’re happy to talk through your situation before you commit to anything.

OUR APPROACH
How we work.

Every Atmos inspection follows the same careful process. We don’t rush, we don’t cut corners, and we don’t leave until we’re confident we have a complete picture of your home’s atmosphere.

We use professional-grade, calibrated instruments — the same standard used by environmental consultants — and we keep them regularly calibrated to ensure every reading is accurate.

Our reports are written the same day as the inspection and delivered within 24 hours. They’re structured to be read in order — starting with a plain English summary, then the detailed findings room by room, then the context and comparison against ICNIRP and UKHSA guidelines.

We are fully insured on every visit — professional indemnity and public liability as standard. No exceptions.

Same-week availability

We offer same-week booking across all London boroughs. Most inspections are confirmed within a few hours of enquiry.

All London boroughs

OUR EQUIPMENT
Professional grade. 
Every time.

The quality of an EMF inspection is only as good as the equipment used and the person interpreting the results. We use calibrated, professional instruments — not consumer-grade devices — and we keep them regularly maintained.

Every measurement is taken multiple times and at multiple positions to ensure accuracy. We test for both low-frequency fields (LF) and high-frequency radio frequency fields (RF), covering the full spectrum of sources relevant to a modern London home.

i

LF measurement

Low-frequency fields from power lines, smart meters and electrical wiring measured in µT and mG

RF measurement

High-frequency radio frequency fields from WiFi, 5G masts and mobile signals measured in V/m

Radon detection

Certified passive alpha track detectors used for long-term radon monitoring in line with UKHSA guidance

Regular calibration

All instruments calibrated regularly against traceable standards to ensure measurement accuracy
What people ask us.

Honest answers to the questions we hear most often.

Is EMF testing worth it?

If you live near a 5G mast, substation or smart meter and want honest, independent data rather than guesswork — yes. We give you real readings with real context, not alarm.

How much does EMF testing cost?

Our EMF inspections start from £149 for a standard home visit. Full home surveys including radon monitoring start from £249. Same-week availability across London.

How long does a EMF inspection take?

A standard EMF inspection takes between 1.5 and 2.5 hours depending on the size of your home. A full home survey takes 3 to 4 hours. You’ll receive your written report within 24 hours.
