UK PEMF regulation involves the MHRA (medical devices) and ASA (advertising claims). PEMF devices marketed for medical purposes require UK Conformity Assessment (UKCA) or CE marking under the Medical Device Regulations. Wellness devices are less regulated. ASA rules govern what claims can be made in advertising — only claims supported by evidence and within the device's regulatory clearance. Saying PEMF 'cures' specific conditions without clearance is non-compliant.
Quick facts
- MHRA: Regulates medical-device PEMF — UKCA / CE marking
- ASA: Regulates what claims advertising can make
- Wellness PEMF: Less regulated — but ASA rules still apply to claims
- Allowed claims: Cleared indications, evidence-supported language
- Not allowed: Cure claims, unsupported medical claims
Practical guidance
See FAQ below for specific scenarios.
Contraindications
Hard exclusions — do not have PEMF if any apply:
- Pacemaker, implantable cardioverter-defibrillator (ICD), or any cardiac electronic device
- Cochlear implant or other implanted electronic hearing device
- Spinal cord stimulator, deep-brain stimulator, vagus nerve stimulator
- Intrathecal pump or implanted drug pump
- Insulin pump (continuous glucose monitors are usually fine — confirm with the clinic)
- Active infection at the treatment site
- Pregnancy — when treatment would be over the abdomen, lumbar spine, or pelvis
Discuss with your GP or specialist before booking if any apply:
- Active malignancy or recent cancer history (oncologist clearance required)
- History of seizures or epilepsy
- Multiple sclerosis or other neurological condition under specialist care
- Anticoagulant therapy (PEMF itself does not thin blood, but bruising risk if local circulation is already compromised)
- Children under 14 (most UK clinics will not treat under-18s without paediatric specialist input)
- Recent surgery within the last 14 days at the treatment site (confirm with surgeon)
NOT contraindications — these are commonly misunderstood:
- Plates, rods, screws and other passive metal orthopaedic hardware
- Dental implants and dental crowns
- Joint replacements (hip, knee, shoulder)
- IUDs (copper or hormonal)
- Tattoos and piercings (jewellery should be removed for the session)
Specific to this condition: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.
Frequently asked questions
Is PEMF a medical device?
Depends on marketing. Marketed for medical purposes — yes, requires UKCA / CE. Marketed as wellness — different category.
Why don't more clinics make stronger claims?
ASA rules. Saying PEMF 'cures' arthritis is non-compliant unless device is specifically cleared for that. Most clinics use 'may help' language for safety.
Are home devices safe to buy?
Look for UKCA / CE marking. Reputable brands comply; some grey-market imports don't.
Can I report misleading claims?
Yes — ASA accepts complaints about misleading advertising.
