This guide covers NHS processes in England. Referral rights, complaints routes, and patient choice rules differ in Wales, Scotland, and Northern Ireland.
NHS organisational structures are changing. NHS England was announced for abolition in March 2025, with its functions transferring to the Department of Health and Social Care over approximately two years (target 2027, subject to primary legislation). The number of Integrated Care Boards (ICBs) in England is also reducing, from 42 to 26, through a series of mergers during 2025-26. The steps and rights described in this guide remain in force; contact names and addresses for escalation may change. The NHS website maintains up-to-date contact details.

Being told your GP won't refer you can feel frustrating - and sometimes frightening. You're not alone: it's one of the most common concerns patients raise, and it often leaves people unsure what to do next.
The good news is that you have more options than you might think. This guide explains why GPs sometimes refuse or decline a referral, what your rights are under the NHS, and the practical steps you can take - including how to escalate your concern, request a second opinion, and when going private might be worth considering.
Why your GP might have declined a referral
It helps to understand the decision before deciding how to respond.
GPs use clinical guidelines - many set by the National Institute for Health and Care Excellence (NICE) - to decide when a referral is appropriate. A GP may decline a referral if they do not believe your symptoms currently meet the clinical threshold for specialist input, if they want to try treatment in primary care first, or if they feel the referral would be unlikely to change your care.
This doesn't automatically mean your concerns are being dismissed - it may mean your GP thinks your condition can be managed in primary care for now.
That said, it is also true that GPs operate under significant resource pressures, and referral decisions can sometimes be inconsistent. If you feel strongly that your symptoms warrant further investigation, you are entitled to say so.
Step 1: Go back and ask your GP to explain
Before taking things further, it's worth going back to your GP and asking them to explain their thinking.
Ask them to explain:
- why they do not think a referral is currently appropriate
- what clinical criteria you would need to meet for a referral
- what the next steps are if your symptoms continue or worsen
- whether there is a different treatment or investigation they would try first
Sometimes a follow-up appointment, a new set of symptoms, or a clearer description of how your condition is affecting your daily life can change the picture. It is also worth asking whether a longer appointment might help - standard GP appointments are typically around 10 minutes, which is rarely enough for a complex conversation.
If you've been keeping a symptom diary or have written notes, bring them along. A clear record of what's been happening - and for how long - makes it much easier for your GP to reassess.
Step 2: Request a second opinion
If you remain concerned after speaking to your GP, you can ask for a second opinion.
This can be from a different GP within the same practice, or you can ask your current GP to refer you to a specialist for their view. The General Medical Council (GMC) - the body that regulates all UK doctors - states in paragraph 18 of Good Medical Practice (2024) that doctors "must recognise a patient's right to choose whether to accept your advice, and respect their right to seek a second opinion." Note that the GMC uses "must" - the stronger formulation denoting a legal or ethical duty - not merely "should".
However, it is important to be clear about what this means in practice:
If your GP declines to arrange a second opinion and you remain unhappy, the most practical immediate step is to register with a different GP practice. You are entitled to do this at any time, without giving a reason. A practice may refuse to register you if you live outside their catchment area (and they do not accept out-of-area patients), if their list is closed, or on other limited reasonable grounds - but any refusal must be given in writing within 14 days with the reason stated. Practices cannot refuse registration on the grounds of immigration status, lack of ID, or lack of a permanent address.

Step 3: Use your right to choose
If your GP agrees that a referral is appropriate but you are unhappy with the provider they have chosen - or if you want to explore faster or more suitable options - you may be able to use your NHS Right to Choose.
Under the NHS Choice Framework, if your GP refers you for planned (non-urgent) care, you have a legal right to choose which hospital or NHS-contracted service you're referred to. This right is rooted in the National Health Service Act 2006 (as amended) and the NHS Constitution for England. It includes some independent and private providers that hold NHS contracts, provided they offer the service at no greater cost to the NHS than a standard NHS hospital referral.
Your GP should tell you about this right at the point of referral. If they do not, you can ask.
Right to Choose applies to your first outpatient referral for a new episode of care. It does not apply if you:
- need urgent or emergency treatment, or have received an urgent referral for suspected cancer or breast symptoms
- are already receiving care and treatment for the same condition and this is an onward referral
- are a prisoner, on temporary release from prison, or held in other prescribed accommodation (such as an immigration removal centre or young offender institution)
- are detained in a hospital under the Mental Health Act 1983
- are a serving member of the armed forces
- are using maternity services (a separate choice regime applies)
- are being referred to services commissioned by a local authority (such as drug and alcohol services)
- are being referred to high-security psychiatric services
If you feel your right to choose has not been offered, you can raise this with your local Integrated Care Board (ICB). For most patients, the ICB is the correct escalation route for concerns about GP and primary care commissioning. NHS England handles complaints only for specific nationally commissioned services (such as specialised commissioning, health and justice services, and armed forces health). The NHS website explains how to find your local ICB.
Step 4: Make a formal complaint about your GP referral
If you think your GP got this wrong - especially if it's affected your health - you have the right to make a formal complaint.
Complain to the GP practice first
Every GP practice must have a complaints procedure. Start by contacting the practice manager in writing. Set out clearly what happened, what you asked for, and why you believe the decision was wrong. Under the Local Authority Social Services and National Health Service Complaints (England) Regulations 2009 (SI 2009/309), practices must acknowledge your complaint within 3 working days of receiving it. They must then send a full written response signed by the responsible person as soon as reasonably practicable - the default "relevant period" for a response is 6 months from the date the complaint was received. If a response will not be sent within that period, the practice must notify you in writing explaining why and when you can expect it.
Contact PALS
If you prefer to raise your concern informally before making a formal complaint, the Patient Advice and Liaison Service (PALS) can help. PALS is a free, confidential service provided by NHS hospital trusts that can help you resolve problems with your NHS care without going through a formal complaints process. Note that PALS teams are based in hospital trusts - if your concern is specifically about a GP practice, the practice itself or your local ICB's Patient Experience team is usually the more relevant first contact. You can find your local PALS team through the NHS website.
Escalate to your ICB or the Parliamentary and Health Service Ombudsman
If you are not satisfied with the practice's response, you can escalate your complaint to your local Integrated Care Board (ICB). Since 1 July 2023, ICBs have taken on operational responsibility for handling commissioner-level complaints about primary care services in England (including GP, dental, optometry and pharmacy services) - this responsibility was previously held by NHS England. If the complaint is still not resolved to your satisfaction, you have the right to take it to the independent Parliamentary and Health Service Ombudsman (PHSO). Two important conditions apply: you must normally have exhausted local resolution first, and complaints to the PHSO should generally be made within 12 months of when you became aware of the problem (the PHSO may extend this at its discretion). For NHS complaints in England, you can approach the PHSO directly - you do not need to go through an MP.
Step 5: Consider going private
If you're not getting anywhere through NHS routes - or you're worried about how long things are taking - it may be worth considering a private specialist.
Do you need a GP referral to go private in the UK?
In most cases, no. You can contact a private hospital, clinic, or specialist directly and book an appointment without a GP referral. Some private providers prefer a GP letter - because it gives the specialist useful background on your medical history - but it is not usually a legal requirement.
If you would like a GP referral letter for a private appointment, your GP can provide one. If they believe a specialist opinion is appropriate, they will usually be willing to do this. If they do not believe a specialist opinion is necessary, they are not obliged to write the referral - but you can still book privately without one.
Returning to NHS care after private treatment
Seeing a private specialist does not mean you lose your NHS care. If a private consultant recommends treatment that is available on the NHS, you can ask to be referred back into NHS care at that point. Department of Health guidance states that a patient who has had a private investigation or diagnosis and then transfers to the NHS for treatment should be placed on the NHS waiting list at the same position as if their original consultation had been within the NHS - prioritisation is based on clinical need and the equivalent NHS referral date, not on the fact of having had a private consultation. In practice, how this works can vary between services, so it is worth discussing this with your GP or the NHS service when you return to NHS care.
NHS vs private: weighing up your options
There is no single right answer. The table below sets out the key differences to help you decide which route makes sense for your situation.
| NHS route | Private route | |
|---|---|---|
| Cost | Free | Typically £150 - £500+ for a first specialist consultation, depending on speciality and location. The UK average initial consultation is around £180-£200; London and psychiatric assessments are frequently at the upper end or beyond |
| Speed | Depends on waiting lists and referral decision | Usually within days to a few weeks |
| Requires GP referral | Yes, for most NHS specialist care | No - you can self-refer in most cases |
| Can return to NHS after | N/A | Yes - in most cases |
| Complaints if unhappy | PALS, ICB, Ombudsman | Private provider's own complaints process |
Costs vary by speciality and location - treat these as a rough guide and check directly with providers for current prices.
