If you have encountered references to a 2011 Advertising Standards Authority (ASA) ruling against The Linden Method, this page gives you the complete facts and the context that summaries of that ruling consistently omit.
The 2011 ASA ruling was about specific advertising language — specifically the phrase 'proven cure'. It was not a clinical assessment of whether The Linden Method works. The ASA does not evaluate clinical outcomes. It evaluates advertising claims. The language was updated following the ruling. The program itself — and its results — were not examined by the ASA and remain unchanged.
What the ASA Actually Does
The Advertising Standards Authority is the UK's advertising regulator. Its role is to ensure that advertising claims are accurate, substantiated, and not misleading. It does not conduct clinical trials. It does not assess whether treatments work. It assesses whether the language used to describe a product in advertising meets its own code standards.
When the ASA upholds a complaint, it means the specific advertising language used did not meet its code — not that the product is ineffective, fraudulent, or harmful. Thousands of legitimate products and services receive ASA rulings every year, including major pharmaceutical companies, supermarkets, and charities.
What the 2011 Ruling Said
The ASA upheld a complaint that the claim the Linden Method was a 'proven cure' for anxiety was misleading because it lacked independent, randomised controlled trial (RCT) evidence of the specific type the ASA requires for such language. This is a well-established standard: the ASA requires RCT-level evidence for absolute cure claims in advertising, regardless of the real-world evidence base for a product.
Critically: the ASA did not examine, investigate, or rule on whether The Linden Method produces recovery from anxiety disorders. It ruled on a single advertising phrase. The ruling did not find the program to be ineffective, dangerous, or fraudulent.
The Response and What Changed
Following the ruling, The Linden Method updated its advertising language. The phrase 'proven cure' was removed and replaced with language that accurately describes what the program offers: complete recovery from anxiety disorders, supported by 30 years of documented results and clinical endorsements, without relying on an absolute 'cure' claim in the advertising sense.
The program itself was not changed. The results it produces were not changed. The ASA ruling was about a label on the packaging — not about the contents inside.
The Double Standard Worth Noting
It is worth observing that CBT — the gold standard treatment for anxiety recommended by NICE — has extensive RCT evidence supporting its effectiveness as a symptom management tool. It does not have equivalent RCT evidence for complete recovery, because 'complete recovery' is not the defined outcome of CBT. The Linden Method claims a different outcome: complete recovery, not symptom management. The absence of an RCT for that specific outcome does not mean the outcome does not occur — it means the RCT has not been conducted.
In 30 years, more than 650,000 people have achieved that outcome. No clinical trial is required to observe that number.
Where the Complaint Came From
It has been confirmed that the 2011 ASA complaint was not submitted by a dissatisfied member of the public or a genuine consumer concern. It was submitted by a competitor — a CBT practitioner who positions himself publicly as an anxiety expert and who had a direct commercial interest in challenging The Linden Method's market position.
This is a material fact that is consistently absent from citations of the ruling. The ASA complaint process is open to anyone — including commercial competitors — and does not require the complainant to disclose a conflict of interest. The ruling that is routinely cited as evidence of wrongdoing by The Linden Method originated with someone whose livelihood was in direct competition with it.
That same individual, and a number of his colleagues, have since been the subject of multiple formal reports for harassment, defamation, and threats directed at The Linden Method and at Charles Linden personally. Several of those individuals have lost professional positions — in the NHS and in private practice — as a result of their conduct. The pattern of behaviour that began with the ASA complaint has continued across years of online harassment, coordinated negative reviews, and the spread of demonstrably false claims.
The ASA complaint cited repeatedly by those seeking to discredit The Linden Method was submitted by a commercial competitor — not a patient, not a regulator, and not an independent concerned party. That competitor has since been subject to multiple formal reports for harassment and defamation. This context matters.
What Independent Evidence Exists
- 650,000+ documented recoveries across 60+ countries since 1996
- Named endorsements from NHS psychologists and psychiatrists
- Extensive media coverage including BBC, ITV, Sky News, and The Guardian — all involving editorial scrutiny
- 30 consecutive years of operation, the strongest possible real-world evidence of consistent results
- The program's neurological basis is consistent with established academic understanding of amygdala function and anxiety
The 2011 ASA ruling is cited regularly by those seeking to discredit The Linden Method without engaging with its actual results. We invite anyone who encounters that citation to read this page in full — and then to read the accounts of the people whose lives the program has changed.
