If you are uncertain about a diagnosis or a suggested treatment plan, you are entitled to ask for a second perspective. MyHSN would encourage you do ask for one.
Whether it’s regarding a GP’s advice or a specialist’s recommendation, here is how to handle the process.
The first step is always to speak with the doctor who provided the initial diagnosis. Be clear and calm about your concerns.
Explain your reasoning: Is it because the symptoms aren’t improving, or because the proposed surgery feels too invasive?
Ask for clarification: Sometimes a second opinion isn’t necessary if the doctor can explain the “why” behind their decision more clearly.
If you are unhappy with the advice from your current GP, you can simply ask to see a different doctor within the same practice.
Speed: This is usually the fastest way to get a fresh set of eyes on your case.
Process: You don’t usually need a formal “referral” for this; you can simply request an appointment with a specific partner or associate at your surgery.
If your concern involves a consultant at a hospital, you can ask your GP to refer you to a different specialist.
The GP’s Role: Your GP will need to write a new referral letter. While they aren’t legally required to do so, they will almost always support a reasonable request if it’s in the interest of your mental or physical well-being.
Wait Times: Be aware that a second specialist referral is subject to standard NHS waiting lists. In 2026, you can use the NHS App to check estimated waiting times for different trusts before choosing where to be referred.
If NHS waiting lists are a concern, you may choose to see a private GP or consultant.
Private GP: You can book these directly without a referral.
Private Specialist: Most private consultants still require a referral letter from your GP to ensure they have your medical context.
Cost: You will be responsible for the consultation fees and any follow-up tests.
To ensure the second doctor has all the facts, you will likely need your medical history, including:
Test results and imaging (X-rays, MRIs).
Consultation notes.
Current medication lists.
Under the Data Protection Act, you have the right to access these records. You can often view a significant portion of this data via the NHS App.
For a full “Subject Access Request” (SAR), contact your GP practice manager. By law, they should provide these records within 28 days, though it is often faster.
Be Specific: Don’t just say “I want another opinion.” Say, “I’m concerned about the side effects of this specific medication; can I see someone who specialises in alternative treatments?”
Prepare Questions: Write down exactly what you want to ask the second doctor so you don’t forget anything during the appointment.
Check Your Rights: While you don’t have a “right” to a second opinion, the NHS Constitution states that the NHS should support you in making informed choices about your care.
