How the NHS Works: Where to Go When You Are Ill in England

The NHS confuses newcomers not because it is bad, but because it is organised differently from almost every other country's system. There is no walking into a hospital to see a specialist, no paying a clinic for a same-day consultation as the default. Instead there is a layered system, and knowing which layer to use saves you hours of waiting — and occasionally your life. This guide describes England; Scotland, Wales and Northern Ireland run their own NHS services with some different rules (prescriptions, for instance, are free there).

The golden rule: match the problem to the service

Here is the whole system in one table. When in doubt between two options, NHS 111 exists precisely to tell you which to use.

The commonest newcomer mistake is going to A&E (Accident & Emergency) with a cold or an earache. You will not be turned away, but you will be triaged as low priority and can wait many hours while ambulance cases go ahead of you. The second commonest mistake is the reverse: sitting on chest pain because you "don't want to bother anyone". Call 999. That is what it is for, and nobody will criticise you for it.

Pharmacies do more than you think

For minor illness, start at a pharmacy (the everyday word is chemist — look for the green cross). The pharmacist is a qualified medicines expert who will advise you for free, no appointment needed, and tell you honestly if you need a doctor. Under the Pharmacy First scheme in England, pharmacists can also assess and treat several common conditions — such as sore throats, earache in certain age groups and uncomplicated urinary infections — and supply some prescription-only medicines directly. For many students, a pharmacy visit replaces a GP appointment entirely.

What is free, and what costs money

Most NHS care is free at the point of use for people living in the UK: GP appointments, hospital treatment, A&E, ambulances, maternity care. The main exceptions in England are prescriptions, dental care and eye care. An NHS prescription charge is a flat fee per item regardless of what the medicine actually costs — check the NHS website for the current amount. Many people are exempt (under-16s, over-60s, certain conditions and benefits), and if you regularly need several items, a prescription prepayment certificate caps the cost. In Scotland, Wales and Northern Ireland, prescriptions are free for everyone.

If you came on a visa of more than six months, you almost certainly paid the Immigration Health Surcharge (IHS) as part of your visa application. This is a per-year fee set by the government, and paying it entitles you to use the NHS broadly as a resident does for the length of your visa — you do not pay again at the hospital door. It does not cover the prescription, dental and optical charges that residents also pay. Current amounts and rules are on GOV.UK.

Referrals: why you cannot book a specialist directly

In the NHS, your GP is the gatekeeper. To see a hospital specialist on the NHS — a dermatologist, cardiologist, orthopaedic surgeon — you first see your GP, who makes a referral if it is clinically needed. This is not bureaucracy for its own sake: GPs resolve most problems themselves and filter hospital demand. The trade-off is the waiting list. Non-urgent referrals can take weeks or months depending on the speciality and your area; suspected cancer and other urgent referrals move much faster on defined pathways. If your symptoms worsen while you wait, go back to your GP — you can be re-prioritised. Private care exists alongside the NHS: paying privately (or through insurance some employers provide) buys speed and choice of consultant, not different medicine.

Interpreters and language support

If your English is not yet confident, you are entitled to ask for a professional interpreter for NHS appointments, including by telephone, at no cost — tell the receptionist when you book. NHS 111 also offers interpreting: say the language you need when the call connects. You should not have to rely on a friend translating your symptoms, and for anything sensitive you really shouldn't. Practices are used to these requests; asking is normal, not an imposition.

Common questions

• Is calling an ambulance expensive? No — 999 calls and NHS ambulances are free. Use them for genuine emergencies only.
• Can I use the NHS before I register with a GP? Emergency care and 111 are open to everyone. But most routine care flows through GP registration, so register early.
• What is an urgent treatment centre versus A&E? An urgent treatment centre handles injuries and illness that need same-day attention but are not life-threatening — often with far shorter waits than A&E. 111 can book you into one.
• Do I pay to see a GP or go to hospital? No. Consultations and NHS hospital treatment are free at the point of use; you only meet charges for prescriptions, dental and optical care in England.

One final note: this guide explains how the system is organised — it is not medical advice. If you are unwell and unsure what to do, call NHS 111 or use 111 online; in a life-threatening emergency, call 999 or go straight to A&E.
