Referrals to specialists (Specialist referral from primary care)

A GP appointment to arrange a referral to a specialist — explaining how NHS and private referrals work, what a referral letter is for, and how to keep your care joined up.

✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review

In short

A referral arranges specialist input and usually comes with a letter giving your history and the reason — this avoids repeated tests and helps the specialist focus.
You can be referred on the NHS (based on clinical need and service criteria) or privately (to a consultant of your choice); some private GPs charge for a referral letter.
A referral is a request for an opinion, not a guarantee of a specific test, treatment or outcome, and your GP is not obliged to act on every private recommendation, particularly prescribing.
Keeping care joined up matters — share specialist letters with your GP, and ask how moving between private and NHS care affects waiting, follow-up and your records.

What is a referral to a specialist?

A referral is when a GP or other clinician arranges for you to see a specialist (a consultant or a specialist service) for an opinion, test or treatment that goes beyond what general practice provides. It usually involves a referral letter that gives the specialist your relevant history and the reason for referral.

Referrals can be on the NHS or private. On the NHS, your GP refers you when a specialist opinion is clinically appropriate, and the specialist sees you based on need and the service's criteria. Privately, you can be referred to a consultant of your choice; most insurers and many consultants prefer a GP referral letter, and some private GPs charge a fee for writing one.

A referral letter matters because it gives the specialist essential background, flags what to focus on, and helps avoid repeated tests. You can also refer yourself to a small number of services without a GP referral. Psychological ('talking') therapies are one example: in England this service is often called NHS Talking Therapies and usually allows self-referral, while the equivalent services in Scotland, Wales and Northern Ireland have different names, eligibility and referral routes.

A referral is a request for an opinion, not a guarantee of a particular test, treatment or outcome. The specialist will make their own assessment, and your GP is not obliged to follow every recommendation from a private provider, especially around prescribing — so good communication between everyone involved is key.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

NHS referral

Your GP refers you to an NHS specialist or service when a specialist opinion is clinically appropriate. You are seen based on clinical need and the service's criteria, sometimes with a choice of provider.

Private referral

You are referred to a private consultant, often of your choice. Most insurers and many consultants prefer a GP referral letter; some private GPs charge a fee to write one.

Self-referral

For a small number of services you can refer yourself without a GP — for example psychological ('talking') therapies (in England often called NHS Talking Therapies for anxiety and depression) and some physiotherapy and sexual health services. Names, eligibility and referral routes differ across England, Scotland, Wales and Northern Ireland, so check what applies where you live.

Urgent or fast-track referral

For certain serious symptoms, GPs use urgent or fast-track pathways so you are seen quickly — for example an urgent suspected-cancer referral. The name and target of this pathway differ across the UK. In England, the Faster Diagnosis Standard aims for cancer to be confirmed or ruled out within 28 days of referral; it does not guarantee a first specialist appointment within two weeks.

Shared care

An arrangement where a specialist and your GP share responsibility for part of your care, such as monitoring a medicine. Your GP only takes this on if it is safe and they are willing and able to.

NHS referral vs private referral

	NHS referral	Private referral
Who you see	Based on need and service criteria	Often a consultant of your choice
Waiting	Can be longer, varies by service	Often faster
Cost	Free at the point of use	You or your insurer pay; letter may have a fee
Records	Usually linked to NHS records	You should share letters with your GP

You can sometimes move between private and NHS care, but it affects waiting lists, follow-up and prescribing. Ask how a private referral will be shared with your GP and what happens if you later move to NHS care.

Preparing for your appointment

Be clear about your main symptoms or concern, how long they have lasted, and what you hope the referral will achieve.
Bring a list of your medicines, allergies, and any relevant test results or previous letters.
Note any treatments you have already tried and how they helped.
If going privately, think about whether you want a particular consultant and check what your insurer needs.
Ask whether a referral is the right next step, or whether tests or treatment in general practice should come first.
Check whether the service accepts self-referral, which may save a step.
Have your GP's details ready so specialist letters can be shared and your care kept joined up.

What happens

In the appointment, the clinician reviews your history, examines you if needed, and discusses whether a specialist opinion is appropriate and which specialty fits. They explain the options — NHS or private — and any choices about who you see.

If a referral is agreed, they write a referral letter summarising your relevant history, current medicines, findings and the specific reason for referral, and send it to the specialist or service. For urgent concerns, a fast-track pathway may be used. They should tell you what to expect next and roughly how long it may take.

You should leave understanding why you are being referred, what the specialist is being asked, what happens while you wait, and what to do if things change. Crucially, your GP should remain in the loop so that whatever the specialist advises can be joined up with the rest of your care.

Is this appointment right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

May not be suitable if…

Using a routine referral for an emergency — severe or rapidly worsening symptoms need urgent or emergency care, not a booked specialist appointment.
Referring before basic tests or first-line treatment that general practice can provide, which may delay rather than speed up care.
A private referral that is not shared with your GP, where care can become disjointed and unsafe.
Expecting your GP to automatically prescribe or monitor a medicine recommended privately without a safe shared-care arrangement.

Delay or rearrange if…

Your symptoms are unstable or worsening and need assessment now rather than a routine referral.
Key information, such as test results, medicines or previous letters, is missing and would help the specialist.
It is unclear which specialty is appropriate, risking referral to the wrong service.
Prescribing or monitoring arrangements have not been agreed for a privately recommended treatment.
Your care is not yet joined up with your GP, risking gaps or conflicting advice.

Alternatives to discuss

Management within general practice, including tests and first-line treatment, before referral.
Self-referral to services that allow it, such as psychological ('talking') therapies (called NHS Talking Therapies in England, and named differently elsewhere in the UK) or some physiotherapy.
An NHS referral instead of private, where waiting time is acceptable.
A specialist advice-and-guidance request, where your GP gets specialist input without a full referral.
Urgent or fast-track pathways where symptoms are serious.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

What matters most to me?

Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.

What are all my options?

Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.

What would make me pause?

Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.

What happens if I do nothing today?

For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.

Benefits

Access to specialist expertise, tests or treatments not available in general practice
A referral letter that gives the specialist your background and avoids repeated tests
Clarity about which specialty is most appropriate for your problem
Faster or urgent access where symptoms need it (for example fast-track pathways)
A choice of provider in many situations, including private consultants
Joined-up care when letters are shared between specialist and GP

Risks & complications

More common

Waiting times, which can be long for some NHS services
Being referred to the wrong specialty if the problem is unclear, causing delay
Repeated or duplicated tests if information is not shared
A fee for a private referral letter that you had not expected

Less common

Care becoming disjointed if private specialist letters are not shared with your GP
Your GP being unable to take on shared care or prescribing recommended privately, leaving a gap
Confusion about who is responsible for follow-up and monitoring
Pressure to have private tests or treatment that may not be needed

Rare but serious

A delay in serious diagnosis if an urgent problem is not recognised and fast-tracked
Harm from a medicine started privately without safe monitoring arrangements

A referral is generally low risk, but the practical pitfalls matter. The main problems are delay (from waiting or being sent to the wrong service), and care becoming disjointed when you move between private and NHS providers. Your GP is not obliged to carry out tests or prescribe medicines recommended by a private provider, so ask how follow-up, prescribing and monitoring will work, and make sure letters are shared so everyone has the full picture.

Published figures to discuss

A referral is an administrative and clinical step rather than a procedure, so it does not carry a meaningful complication 'rate'. The relevant risks are practical: delay from waiting lists or referral to the wrong service, duplicated tests, and care becoming fragmented when moving between private and NHS providers. These depend on the specialty, the service and how well information is shared, so no fixed percentages are given here.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no physical recovery. 'Afterwards' means the referral letter being sent, the wait for a specialist appointment, and making sure your care stays joined up while you wait and after you are seen.

During the appointment

You discuss whether a referral is right, which specialty fits, and NHS or private options. If agreed, the reason and plan are explained.

Within days

The referral letter is written and sent. For private referrals, you may receive a copy; some private GPs charge a fee for the letter.

Waiting for the appointment

Timing depends on the service and urgency. You should know what to do if symptoms change, and who to contact while you wait.

After the specialist visit

The specialist sends a letter back with their assessment and recommendations. This should be shared with your GP so your care is joined up.

Ongoing care

Responsibility for tests, prescribing and follow-up should be clear. Shared care is only set up if it is safe and your GP agrees to it.

What's normal — and not a worry

A short wait for the referral letter to be issued
A variable wait for the specialist appointment, depending on the service
Being asked to share or chase letters between providers
Your GP reviewing the specialist's advice before acting on it

Aftercare

Keep a copy of your referral and any specialist letters.
Make sure specialist letters are shared with your GP so your records are complete.
Check who is responsible for any tests, prescriptions and follow-up.
If your symptoms change or worsen while you wait, contact your GP or seek urgent care.
If you move between private and NHS care, ask how this affects waiting lists and follow-up.
Clarify, before starting any privately recommended medicine, who will prescribe and monitor it.
Ask what to do if the specialist recommends something your GP cannot provide.
Keep one up-to-date medicines list that all your clinicians can see.

Before your appointment

A clear note of your main symptoms and what you want from the referral
An up-to-date list of medicines and allergies
Relevant test results and previous letters
Your insurer's requirements, if going privately
Questions about waiting times, costs and follow-up
A copy of the referral letter, if provided
Your GP's details so specialist letters can be shared

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your GP gives you.

Results & realistic expectations

A 'good' result is being seen by the right specialist, with the right information, and your care staying joined up — not simply being referred. The most useful referral clearly states the question, includes your relevant history, and leads to a specialist letter that informs the rest of your care.

A referral cannot guarantee a particular diagnosis, test, treatment or outcome; the specialist makes their own assessment, and recommendations still need to fit safely with your overall care. The value lies in getting the right expertise at the right time and making sure everyone involved works from the same picture.

How long it lasts

A referral relates to a specific problem at a point in time. Once the specialist episode ends, ongoing care usually returns to your GP, and a new referral may be needed for a new or recurring problem. Any arrangements for shared monitoring or prescribing should be reviewed and kept under your GP's oversight.

Related tests, treatments or support

Referrals often follow on from a GP consultation, tests or chronic disease management, and may lead to specialist tests, treatment or surgery. For mental health, self-referral to a psychological-therapies service (called NHS Talking Therapies in England, and named differently elsewhere in the UK) may run alongside GP support. Good practice is to keep your GP informed throughout so different parts of your care connect.

Follow-up & long-term care

After a referral, the specialist should write back with their assessment and recommendations. Responsibility for follow-up, tests and prescribing should be clearly agreed between the specialist and your GP. Shared care is only set up where it is safe and your GP is willing and able to take it on. Letters should be shared so your records are complete.

Repeat, follow-on and what comes next

A referral may be redirected if it reaches the wrong specialty, causing delay.
A new referral is usually needed for a new or recurring problem once an episode ends.
Shared-care or prescribing arrangements may need renegotiating and are kept under GP oversight.
If symptoms change while waiting, the urgency or destination of a referral may need revisiting.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

A clear referral letter stating the question and including your relevant history.
Specialist letters shared promptly with your GP so records are complete.
Agreed responsibility for follow-up, tests, prescribing and monitoring.
Clear advice on what to do, and who to contact, if symptoms change while waiting.
Safe, explicit shared-care arrangements where ongoing monitoring is needed.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

Whether the referral is NHS (free at the point of use) or private
Whether a fee is charged for writing a private referral letter
The specialist's consultation fee and any tests, if going privately
Whether your insurer covers the referral and what it requires
Whether follow-up appointments and any monitoring are included
Whether moving between private and NHS care affects later costs

Make sure your written quote includes

Whether there is a fee for the referral letter
What your insurer requires before a private referral
The specialist's likely consultation and test fees, if private
Who is responsible for follow-up, prescribing and monitoring afterwards
What happens if your GP cannot provide a privately recommended treatment
How and when letters are shared with your GP
How moving between private and NHS care would be handled

On the NHS? GPs can refer you on the NHS when a specialist opinion is clinically appropriate, and you can also be referred privately; some private GPs charge for a referral letter, and sharing specialist letters with your GP keeps your care joined up.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Choosing a specialist safely

Check the GP is on the GMC Specialist Register for this area.
Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
You're entitled to time to consider and to have your questions answered before you agree — the GP who looks after you should explain it, not a salesperson.
Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
You're entitled to your total cost in writing — including any follow-up — before you decide.

What are my NHS and private options, and how do waiting times and costs compare?
Will there be a fee for the referral letter, and what does my insurer need?
How will the specialist's advice and any prescribing or monitoring be handled afterwards?
What should I do, or who should I contact, if my symptoms change while I wait?
How will letters be shared so my GP has the full picture?
Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
Will you be the GP who carries out my appointment, and who looks after me afterwards?
What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
What does a realistic result look like — and what can this appointment not achieve?
What are my options, including waiting, doing nothing for now, or choosing a different approach?
Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
What is the total cost in writing, including any follow-ups, and how much time do I have to decide?

Frequently asked questions

Do I always need a GP referral to see a specialist?

Not always. Some services accept self-referral — for example psychological ('talking') therapies, called NHS Talking Therapies in England, though the names, eligibility and referral routes differ in Scotland, Wales and Northern Ireland. But for most specialists, a GP referral letter is needed or strongly preferred — it gives the specialist your background and is usually required by insurers.

Can I be referred privately and then move to the NHS, or the other way round?

Often yes, but it affects waiting lists, follow-up and prescribing. For continuity, a private consultant may ask your GP to refer you on the NHS for ongoing care. Ask how any move will be handled and make sure letters are shared.

Why might there be a fee for a referral letter?

Writing a private referral letter is not an NHS service, so some private GPs charge for it. Check whether a fee applies, and what your insurer requires, before you book.

Will my GP do whatever the private specialist recommends?

Not automatically. Your GP is not obliged to carry out tests or prescribe medicines recommended by a private provider, and will only do so if it is clinically appropriate and safe. Ask in advance how prescribing and monitoring will work.

What is shared care?

It is when a specialist and your GP share responsibility for part of your care, such as monitoring a medicine started in hospital. Your GP only takes this on if it is safe and they are willing and able to, under a clear agreement.

How long will I wait to be seen?

It depends on the service and how urgent your problem is. Private referrals are often faster; NHS waits vary, with urgent and fast-track pathways used for serious symptoms. Ask roughly what to expect and what to do if you get worse.

What should I do if I need urgent advice while I wait to be seen?

If it is life-threatening — for example chest pain, severe breathlessness, or signs of a stroke — call 999 or go to A&E anywhere in the UK. For urgent but not life-threatening advice, use NHS 111 in England, Scotland or Wales. In Northern Ireland, contact your GP out-of-hours service or your local HSC Trust's Phone First service. You can also contact the GP practice that made the referral.

Why should I share private letters with my GP?

So your records are complete and your care is joined up. Your GP coordinates your overall care, and sharing specialist letters avoids duplicated tests, conflicting advice and gaps in follow-up.
