Second Medical Opinion UK (2026): How to Get One Through Health Insurance, Privately or on the NHS
A second medical opinion can change a diagnosis, change a treatment plan, or give you the confidence to go ahead. This guide covers what each UK insurer actually offers, the pre-authorisation steps that stop claims being declined, what a private second opinion costs without insurance, how to get one on the NHS, and ready-to-use templates for your GP and your insurer.
Quick Answer
Most UK health insurers will pay for a second medical opinion, but for the majority it is simply another outpatient consultation: it needs pre-authorisation before you book, a consultant recognised by your insurer, and it comes out of your outpatient benefit. AXA Health runs a dedicated second opinion service on plans with the outpatient option; Bupa arranges one through a second recognised consultant (its separate “Second Medical Opinion service” is Bupa Global’s international product); The Exeter lists an expert medical opinion benefit; Aviva, Vitality and WPA go through their digital GP or clinical team.
Without insurance, a private consultant’s initial consultation costs about £150 to £300, and you can see anyone. On the NHS there is no legal right to a second opinion, but a GP or consultant will usually arrange one if you ask. Whatever the route, the two things that make a second opinion worth having are a sub-specialist rather than a generalist, and your records sent ahead.

When a Second Medical Opinion Is Worth Getting
A second opinion is most useful before something irreversible: major surgery, a cancer treatment plan, a diagnosis that will mean lifelong medication, or any case where the first consultant seemed uncertain or you did not understand the reasoning. It is routine in oncology and orthopaedics, where there are often two reasonable paths, and it is where the biggest gaps in treatment choice show up. It is less useful for straightforward, well-evidenced conditions where the plan is standard. Doctors expect to be asked; a good consultant will help you find the right person to ask.
The value comes from depth. A second opinion from a general orthopaedic surgeon on a hip problem adds little; one from a hip arthroplasty specialist can change the operation. The same goes for a hepatobiliary oncologist versus a general oncologist. Our guides to choosing a private consultant and open referrals versus named consultants explain how to find and name the right person.
What Each Insurer Offers for a Second Opinion
Access routes differ more than the policy documents suggest. This is the picture as of October 2026; confirm your own plan’s wording, because products and tiers vary.
| Insurer | What exists | How you access it | What it costs you |
|---|---|---|---|
| AXA Health | A dedicated second opinion service, listed under the outpatient diagnosis and care option on the AXA Health Plan. When it launched in 2013 it covered the consultation and any tests and scans, with the excess and outpatient limit not applying | Through AXA’s team or Doctor at Hand, which can refer you; pre-authorisation required | Check your current handbook for whether the excess and limits apply; on the original service they did not |
| Bupa | No separate product on UK cover. A second opinion is a consultation with another Bupa-recognised consultant. Bupa Global’s “Second Medical Opinion service” is for its international plans, not UK domestic policies | GP referral, Blua Health digital GP, or Bupa Direct Access for eligible conditions; pre-authorisation required | Paid from your outpatient benefit, subject to any excess and outpatient limit |
| Aviva | Second opinion treated as a further outpatient consultation with a recognised consultant. Aviva’s Smart Health service, on its protection policies, includes an expert second medical opinion provided by a third party | Aviva Digital GP can refer; Expert Select plans restrict which consultants you can use; pre-authorisation required | Outpatient benefit, excess and limits apply |
| Vitality | No separately advertised service; second opinion arranged as a further consultation. Mental health follows its own pathway | Vitality GP app can refer; pre-authorisation through Vitality’s care team | Outpatient benefit, excess and limits apply |
| WPA | Arranged case by case through WPA’s clinical team, including the option of NHS private patient units | Call WPA’s helpline; pre-authorisation required | Depends on your schedule of benefits |
| The Exeter | An expert medical opinion benefit set out in its policy documents, delivered by a third-party provider | Through The Exeter’s member services | Check the benefit wording; typically separate from the outpatient limit |
Two things apply everywhere. A second opinion on a condition that is excluded from your policy, usually because it is pre-existing, is also excluded. And your insurer must authorise the appointment before you attend; see pre-authorisation codes explained. The claims process for each insurer is in our guides: Bupa, AXA, Aviva, Vitality and WPA.
Several insurers and employers buy their expert opinion services from Teladoc Health, whose UK service works on records rather than appointments: a GP takes your history, writes a case summary, a matched specialist (UK or international, from a pool of more than 50,000) reviews it and writes a report, and the GP goes through the findings with you. It is fast and thorough, but you do not meet the specialist, so it suits diagnosis and treatment-plan questions better than “which surgeon should operate”.
Step by Step: A Second Opinion Through Your Health Insurance
- Get a written summary from your first consultant or GP: diagnosis, key findings, the treatment proposed and why. Ask for copies of imaging and reports, or confirmation of where they are held. Without this the second consultant starts from nothing.
- Identify the right sub-specialty (ask the first consultant; most will suggest a name) and check the consultant and hospital are recognised by your insurer for your plan. On guided plans the insurer will give you the list.
- Call your insurer for pre-authorisation before booking anything. Say it is a second opinion, give the condition and the consultant’s name, and note the reference number and its validity dates. Ask for it in writing.
- Send your records ahead. Ask the consultant’s secretary how they want imaging and letters (most accept uploads or a disc). A consultant who has read everything gives you a better consultation and avoids a second appointment.
- Attend, by video or in person. Imaging-driven questions suit a video consultation; surgical questions usually need an examination. Ask for a written outcome letter with the consultant’s recommendation and reasoning.
- If new tests are recommended, pre-authorise them separately before they are booked. The original authorisation covers the consultation, not an MRI the second consultant wants. See does health insurance cover diagnostics?
How quickly you are seen depends on the consultant rather than the insurer: see how long it takes to see a private specialist and private specialist appointment wait times.
Getting a Second Opinion From a Private Doctor Without Insurance
You do not need insurance, a referral or your first consultant’s permission to pay for a second opinion. Many private consultants accept self-referred patients for an initial consultation, and those who want a referral letter will accept one from a private GP, often the same day.
- Cost: an initial private consultation is typically £150 to £300, with London and senior sub-specialists at the top. Some consultants offer a cheaper records-only written review. Any new tests are extra: a private MRI from about £300, a CT from about £350; see the scans and tests hub.
- What to take: your first consultant’s letter, all imaging (ask the hospital for a copy; you are entitled to it), blood and pathology results, and a one-page list of your questions.
- Finding the right person: ask the first consultant for a name, look for a sub-specialist, and check they are on the GMC specialist register. Our guide to choosing a consultant covers how to read a consultant’s profile.
- Afterwards: you can take a private second opinion back to the NHS. The written report has the same clinical weight, and the NHS can carry out whichever treatment is agreed; see mixing NHS and private treatment.
If you are self-paying for the second opinion and the treatment that follows, the private surgery hub has fixed-price guides, and insurance versus paying direct runs the arithmetic for next time.
Second Opinions on the NHS
There is no legal right to a second opinion on the NHS, but one is rarely refused: ask your GP to refer you to a different consultant, or ask the consultant directly to arrange one. You can also use the NHS right to choose to be referred to a different hospital for a first outpatient appointment. The limitation is time. A second NHS outpatient appointment joins the queue like any other, which is why many people pay for the second opinion privately and return to the NHS for treatment. See NHS referral waiting times and the NHS waiting times hub.
Choosing the Right Specialist
- Sub-specialism first. A second opinion from someone with the same training as the first adds little; the value is in deeper expertise in your exact problem.
- Independence second. Ideally a consultant at a different hospital, not the first consultant’s colleague down the corridor, especially for surgery.
- Recognition third, if insured. The consultant and hospital must be recognised by your insurer for your plan tier; on guided plans the choice is narrower and the premium cheaper. Using an unrecognised consultant means a shortfall or a declined claim.
- Timing. A second opinion is most valuable before a procedure is scheduled. If surgery is already booked, tell both consultants, and ask whether a short delay is safe.
For cancer, where second opinions are commonest, our guides to cancer cover on health insurance, Saga cancer cover and The Exeter cancer cover explain what each policy pays for once treatment starts.
Templates for Your GP and Your Insurer
Adapt these to your condition. Email is better than a phone call because it leaves a record.
| Template 1: asking your GP or consultant for a referral |
|---|
| Subject: Referral for second medical opinion, [your name] Dear Dr [name], Please could you refer me for a second medical opinion on my diagnosis of [condition]? I would be grateful if the referral could include a summary of the diagnosis and key findings, copies of imaging and reports or details of where they are held, and any questions you would suggest I ask. If you can recommend a sub-specialist in [field], that would be very helpful. Thank you, [your name] |
| Template 2: asking your insurer for pre-authorisation |
|---|
| Subject: Pre-authorisation request, second medical opinion, policy [number] Dear [insurer] claims team, I would like to obtain a second medical opinion on [condition], for which I was first seen by [consultant] on [date]. Please could you confirm: whether a GP referral is required; which consultants or networks are approved for this specialty on my plan; any excess, limits or co-payments that apply; and a pre-authorisation reference with its validity dates. Please reply by email so I have the authorisation in writing. Thank you, [your name] |
Mistakes That Get Second Opinion Claims Declined
- Booking before pre-authorisation. The single commonest reason a claim is refused. The reference must exist before the appointment.
- An unrecognised consultant or hospital. Leads to a shortfall between the fee and what the insurer pays, or a declined claim. Check both for your plan tier.
- Records not sent ahead. The consultant cannot give an opinion on scans they have not seen; you pay for a second appointment.
- Assuming tests are covered. New scans the second consultant orders need their own authorisation and count against your outpatient limit.
- No written outcome. If the two consultants disagree, you need both recommendations in writing for the insurer to fund the agreed next step. If a claim is refused, how to appeal a rejected claim sets out the process.
Documents to Keep
- The pre-authorisation reference and its validity dates, in writing.
- The referral letter, with the diagnosis summary.
- Copies of all imaging, blood and pathology results reviewed.
- The second consultant’s outcome letter, with any procedure codes if treatment follows.
- Any correspondence with the insurer about limits, excess and recognition.
If the second opinion leads to treatment, the rest of your policy takes over: outpatient limits, hospital lists and excess. Our private health insurance guide and best health insurance UK cover how the policies compare, and whether cover is worth it if you are weighing it up after paying for an opinion yourself.
FAQs: Second Medical Opinion UK (2026)
Does health insurance cover a second medical opinion?
Usually yes, as long as it is pre-authorised and the consultant is recognised by your insurer. For most UK insurers a second opinion is simply another outpatient consultation, so it is paid from your outpatient benefit and may be subject to your excess and outpatient limit. AXA Health runs a dedicated second opinion service on plans with the outpatient option, and The Exeter lists an expert medical opinion benefit. Pre-existing conditions excluded from your policy stay excluded, including a second opinion on them.
Does Bupa offer a second opinion?
Yes, but not as a separate product. On Bupa UK health insurance a second opinion is a consultation with another Bupa-recognised consultant, arranged by GP referral or through Bupa’s Direct Access service for eligible conditions, and paid under your outpatient benefit after pre-authorisation. The Bupa Second Medical Opinion service you may see online belongs to Bupa Global, its international plans, and is not part of UK domestic cover.
Do I need a GP referral for a second opinion?
Often, but not always. Insurers whose digital GP can refer you (AXA Doctor at Hand, Bupa Blua Health, Vitality GP, Aviva Digital GP) let you get the referral the same day without seeing your NHS GP. Some conditions can go through direct access without a GP. Either way your insurer needs to pre-authorise the appointment before you book it, even where the clinic itself does not ask for a referral.
How do I get a second medical opinion in the UK?
Three routes. Through health insurance: get a referral from your GP or the insurer’s digital GP, call the insurer for pre-authorisation, choose a recognised consultant in the right sub-specialty, send your records ahead, and attend. Self-pay: book a private consultant directly, typically £150 to £300 for an initial consultation, and bring your existing scans and letters. On the NHS: there is no legal right to a second opinion, but a GP or consultant will usually arrange one if you ask, and you can also ask to be referred to a different hospital under the NHS right to choose.
How much does a private second opinion cost without insurance?
A private consultant’s initial consultation in the UK typically costs £150 to £300, with London and senior sub-specialists at the top of the range, and a records-only written review sometimes less. If the second consultant wants new tests, those are charged separately: an MRI from about £300, a CT from about £350. Bring your existing imaging and reports so they are not repeated.
Can I choose any specialist for a second opinion?
Not if you want your insurer to pay. The consultant and hospital must be recognised by your insurer for your plan, and on guided or restricted plans the choice is narrower. Using an unrecognised consultant means a shortfall or a declined claim. If you are paying yourself, you can see anyone, including a consultant in another city or a records-based expert review.
Does getting a second opinion delay my treatment?
Not much if you move quickly. A records-based review or a video consultation can be done within days, and most second opinion appointments happen within one to two weeks privately. Send your imaging and letters before the appointment so the consultant has reviewed them, and keep your first consultant informed so a scheduled operation can be held or confirmed. For urgent conditions, ask the first consultant whether a short delay is safe.
Will my insurer pay for extra tests the second consultant orders?
Usually, if they are clinically needed, within your outpatient benefit and pre-authorised separately. Do not assume the original authorisation covers new scans; ring the insurer with the consultant’s request before the test is booked. If the two consultants disagree, ask both for written recommendations; insurers will generally fund the agreed next step when it is documented.
Important Information
This 2026 guide is independent general information, not medical, legal or financial advice. Whether a second opinion is appropriate, and how urgent your treatment is, are matters for your doctors. Insurer processes, access routes and benefit wording vary by product, tier and policy year and change; the insurer summaries here are from the insurers’ published material and press reports as of October 2026, and you must confirm the process for your own plan before booking. Private consultation prices are typical UK ranges, not quotes. Going Private UK is not affiliated with any insurer or provider named. If you compare quotes through this site, we may receive a commission from our FCA-regulated partners at no cost to you; this does not influence our guides.
