A General Medical Consent Form is a written document used in England and Wales to record a patient's informed consent to a proposed medical procedure, treatment, examination, or intervention. It captures the patient's confirmation that they have been given sufficient information about the proposed treatment — including its nature, purpose, material risks, and reasonable alternatives — to make a genuinely autonomous decision about whether to proceed.

The legal framework for medical consent in England and Wales is principally governed by the common law, the Mental Capacity Act 2005, and the landmark Supreme Court decision in Montgomery v Lanarkshire Health Board [2015] UKSC 11. Montgomery replaced the historic Bolam test (Bolam v Friern Hospital Management Committee [1957] 1 WLR 582) with a patient-centred standard of disclosure. Under the Montgomery test, a clinician must disclose any risk that a reasonable person in the patient's position would consider significant, as well as any risk the clinician knows the particular patient would consider significant, regardless of whether a responsible body of medical opinion would choose to disclose it.

For most adult patients, consent requires capacity as defined in section 2–3 of the Mental Capacity Act 2005: the ability to understand, retain, use or weigh, and communicate the information relevant to the decision. Adults are presumed to have capacity unless the contrary is established. For children under 16, a clinician must assess whether the child is 'Gillick competent' (Gillick v West Norfolk and Wisbech AHA [1986] AC 112), meaning they have sufficient maturity to understand the nature and consequences of the proposed treatment. Young people aged 16–17 are presumed capable of consenting under section 8 of the Family Law Reform Act 1969. Where a child lacks Gillick competence, a person with parental responsibility under the Children Act 1989 must consent.

This General Medical Consent Form is designed for use in private medical practice, independent healthcare facilities, and allied health settings in England and Wales. NHS providers may have their own consent forms, which reflect the Department of Health and Social Care's standard consent forms. Our template covers all key elements of a valid, legally compliant consent process: patient identification, procedure description, disclosure of material risks under Montgomery, alternatives including no treatment, anaesthesia consent, health data processing under UK GDPR Article 9, and the patient's right to withdraw consent. It is governed by the laws of England and Wales.

A General Medical Consent Form is required whenever a healthcare provider proposes to carry out an invasive or significant medical procedure, treatment, or examination on a patient who has the capacity to consent, and wishes to create a written record of the consent process.

Surgical procedures of any kind — from minor excisions under local anaesthetic to major surgery under general anaesthetic — require a signed consent form before the procedure begins. The consent form documents that the patient was informed of the risks of the specific procedure and chose to proceed. For procedures involving general anaesthesia, separate consent to the anaesthesia itself is required.

Diagnostic procedures that are invasive or carry a material risk — such as colonoscopy, bronchoscopy, lumbar puncture, or biopsy — require written consent. Non-invasive diagnostic procedures (such as an MRI scan or blood test) generally do not require a formal written consent form, though the patient's implied consent should be recorded in their clinical notes.

Private healthcare consultations and treatments — including private dental treatment, cosmetic procedures, physiotherapy, chiropractic treatment, and alternative therapy — may require written consent, particularly where the procedure involves a material risk. Private providers are not bound by NHS consent policies and must implement their own compliant consent processes.

Research and clinical trials require separate, specific informed consent under the UK Policy Framework for Health and Social Care Research and the Medicines for Human Use (Clinical Trials) Regulations 2004. A standard medical consent form is not sufficient for research purposes.

A signed consent form is important not only as legal compliance, but as evidence in any clinical negligence dispute. Under Montgomery [2015] UKSC 11, if a patient can demonstrate that a material risk was not disclosed and they would have declined the procedure if it had been, the clinician may be liable in negligence, even if the procedure was performed to a competent standard. A well-drafted consent form, combined with contemporaneous clinical notes, is the clinician's best protection.

Patient Identification — The patient must be clearly identified by full name, date of birth, NHS number (if known), and residential address. Correct identification prevents the risk of performing a procedure on the wrong patient — a 'Never Event' under NHS England's Never Events Policy and Framework.

Proposed Procedure Description — The proposed procedure must be described in sufficient detail for the patient to understand what will happen, how it will be performed (including the approach — laparoscopic, open, under anaesthetic, etc.), how long it will take, what to expect during recovery, and what the likely outcome will be both with and without the procedure. The description must use plain language the patient can understand, supplemented by technical terminology for the clinical record.

Material Risks Under Montgomery — The Montgomery test requires disclosure of any risk that a reasonable person in the patient's position would consider significant, and any risk known to be important to this particular patient. The consent form should separately identify 'common or significant risks' (those likely to affect a significant proportion of patients) and 'serious risks, even if rare' (those that may be statistically uncommon but are of great importance to the patient). Risks should be expressed in terms the patient can understand (e.g. 'approximately 1 in 100 patients'), not purely in statistical terms.

Expected Benefits — The consent form should set out the expected clinical benefits of the proposed procedure: what the procedure is intended to achieve, what improvement in the patient's condition is expected, and how long recovery is expected to take.

Alternatives, Including No Treatment — Under Montgomery, the clinician must inform the patient of reasonable alternative treatments and management options, including the option of no treatment (watchful waiting or conservative management). The patient must be able to weigh the alternatives against the proposed procedure to make a genuinely informed decision.

Anaesthesia and Sedation — Where the procedure involves any form of anaesthesia or sedation, the type, risks, and the patient's known allergies and adverse drug reactions must be separately recorded and consented to. Anaesthetic consent should be obtained by the anaesthetist or a clinician with appropriate knowledge of the proposed anaesthetic.

Parental or Guardian Consent — Where the patient is a child under 16 who does not demonstrate Gillick competence, or an adult who lacks capacity, consent must be obtained from the appropriate authorised individual: a person with parental responsibility (under the Children Act 1989) for a child, or an attorney under a Health and Welfare Lasting Power of Attorney or a court-appointed deputy (under the Mental Capacity Act 2005) for an adult lacking capacity.

Health Data Processing Consent — Health data is special category data under UK GDPR Article 9. Private healthcare providers processing health data with the patient's consent must obtain explicit consent for data processing and inform the patient of their rights (access, rectification, withdrawal of consent). The consent form should specify the retention period for medical records in accordance with the NHS Records Management Code of Practice 2021.

Right to Withdraw — The patient must be informed that they can withdraw consent at any time before the procedure begins, without penalty or adverse effect on the care they receive. Withdrawal of consent after a procedure has begun may not always be practicable and the clinician must be informed of this.

Clinician Confirmation — The attending clinician should countersign the consent form to confirm that the consent process was properly conducted: that the risks and alternatives were explained, that the patient appeared to understand and consent freely, and that the information was communicated in language the patient could understand.
