Getting a second opinion in the UK

Patients sometimes feel awkward asking for a second opinion, as if it is an implied criticism of the first clinician. It is not. A second opinion is a normal part of UK clinical practice, the GMC explicitly supports the patient's right to ask for one, and most clinicians welcome the request when it is made clearly.

This article sets out when a second opinion is worth asking for, how to request one through the NHS, how to arrange one privately, and what happens afterwards. Sources are at the end.

When a second opinion is worth asking for

Several situations reliably benefit from a second opinion.

• A diagnosis you are not sure fits. If the clinical explanation you have been given does not match how you feel or the pattern of your symptoms, another clinician may see something different.

• A treatment choice with significant trade-offs. Major surgery, starting long-term medication, or a decision between two materially different treatment options are all good reasons for a second opinion.

• A new or serious diagnosis. Cancer, complex cardiac, major neurological, and other serious diagnoses often benefit from a second clinician's view, either at the point of confirmation or before starting treatment.

• A rare or unusual condition where specialist experience varies widely between clinicians.

• A decision you find hard to make. Sometimes the clinical question is straightforward but the decision is not. A second conversation with another clinician can help.

• A situation where you feel unheard or dismissed. Not every clinical encounter lands well. A second opinion with a different clinician often recovers ground that was lost in the first.

A second opinion is not usually the right move for:

• Routine follow-ups where nothing has materially changed.

• Standard minor conditions that are resolving.

• Seeking a different answer when the answer you have is clinically sound and just not what you wanted to hear.

Your legal right to ask

The GMC's Good Medical Practice requires doctors to support patients who want a second opinion. The NHS Constitution for England does not grant a specific statutory right to a second opinion but does protect patient involvement in treatment decisions.

In practice, any UK patient who asks for a second opinion from their GP or specialist will be supported. Refusals are rare and usually reflect communication rather than obstruction.

How to ask for a second opinion on the NHS

The practical steps are straightforward.

• Ask your GP or specialist directly. Say clearly: "I would like a second opinion on this diagnosis (or this treatment plan)." Most clinicians respond to a direct ask.

• Be clear about what you want. A second opinion from another clinician in the same specialty? A different specialty's perspective? A specific named consultant? The clearer your ask, the easier the response.

• Accept that the second opinion may confirm the first. Second opinions often agree with the original. That confirmation itself is useful.

• Take your records with you. The second clinician benefits from seeing the first clinician's letters, scans, and test results. NHS to NHS referrals usually handle this automatically through the electronic record.

The NHS does not guarantee a second opinion but in practice supports most reasonable requests. If an NHS clinician declines, you can:

• Ask to see a different consultant in the same department (often easier than a cross-department referral).

• Use NHS Right to Choose to direct a referral to a different provider.

• Raise the request with your GP, who can initiate a new referral if the specialist has declined.

How to arrange a private second opinion

A private second opinion is often the fastest route when the NHS wait for a second specialist consultation would be long. It is particularly useful for:

• Time-sensitive decisions. A second opinion on a new cancer diagnosis, for example, often needs to happen within weeks rather than months.

• International or UK-wide specialist expertise. Some conditions have a small number of clinicians nationally with deep experience. A private consultation can be easier to secure than an NHS out-of-area referral.

• A different system altogether. Sometimes a patient wants a view from a clinician outside the specific NHS trust that made the original diagnosis.

### The process

• Gather your records. Ask the NHS for a copy of your medical record, including specialist letters, scan reports, and test results. You can do this through the NHS App, through your GP, or through the hospital's Subject Access Request process.

• Choose a private specialist. The Private Healthcare Information Network (PHIN) publishes consultant-level performance data. Your NHS GP may be able to suggest specific names. Some patient-support charities maintain lists of consultants experienced in specific conditions.

• Book the consultation. Private specialists typically book through their secretary, their private hospital, or their website.

• Bring the records and a written summary. Not all private specialists will have read your records in advance. A written one-page summary of your situation and the specific question you want addressed is always useful.

• Get the consultation letter. The private specialist's letter is the document you will hand back to your NHS GP, to your NHS specialist, or to any subsequent clinician. Ask for a copy.

### Typical cost

A first private specialist consultation in most specialties runs £200 to £400. Complex second opinions or specialty consultations with specific national experts can cost more. Further investigations (scans, blood tests) are billed separately.

What to do with the second opinion

Two outcomes are common.

• The second opinion agrees with the first. Useful confirmation. The original plan continues, with more confidence. Hand the second-opinion letter back to your NHS GP and NHS specialist so the record shows the confirmation.

• The second opinion differs. This is the more complex outcome. It does not mean one clinician is right and the other is wrong; it often means the two are weighing trade-offs differently. Options include:

• Going back to the first clinician with the second opinion's letter and asking them to respond to the different view.

• Requesting a multidisciplinary team (MDT) discussion, which brings several clinicians together around the case.

• Asking for a third opinion, specifically from a senior clinician in a specialist centre.

• Making a decision that reconciles the two views yourself, after talking it through with someone you trust.

A difference between first and second opinions is not automatically a sign of error. Clinical medicine often involves genuine uncertainty, and the right answer is rarely stark.

What a second opinion does not do

Two honest limits.

• It does not guarantee the outcome you want. Both clinicians may agree with a diagnosis or treatment you were hoping to see differently. A second opinion is a view, not a negotiation.

• It does not replace the first clinician. A second opinion is a consultation, not a transfer of care. Your ongoing care usually stays with your original team unless you explicitly change provider.

A second opinion is most useful as a way to think clearly about a decision, not as a way to overturn one.

If you feel the first clinician did something wrong

A second opinion is not the right mechanism for complaints about clinical care. If you believe something has gone wrong, the appropriate routes are:

• The trust or practice complaints process for a specific care incident.

• The [Parliamentary and Health Service Ombudsman](https://www.ombudsman.org.uk/) if the trust or practice complaints response does not resolve the concern.

• The [General Medical Council](https://www.gmc-uk.org/) for concerns about a doctor's conduct or fitness to practise.

• [NHS Resolution](https://resolution.nhs.uk/) for clinical negligence claims.

A second opinion can run in parallel with any of these processes but does not substitute for them.

The summary

A second opinion is a normal and supported part of UK clinical practice. It is worth asking for on serious diagnoses, significant treatment decisions, and when a first clinician's explanation does not fit. NHS routes exist and are widely used; private routes are often faster and useful for time-sensitive decisions. The process is simpler than patients expect: ask clearly, bring your records, and hand the letter back to your main clinical team.

A second opinion that agrees is useful confirmation. A second opinion that differs is a prompt to think more carefully, not an automatic answer. Either way, it belongs in UK clinical practice as a patient entitlement and as a clinical tool.
