Your NHS rights
What happens if the NHS misses your 18-week target?
The NHS Constitution sets a clear standard: most patients in England should start consultant-led non-urgent treatment within 18 weeks of referral. If your wait has gone beyond that, here's a calm, accurate guide to what it means and what you can do.
What "RTT 18 weeks" actually means
RTT stands for "Referral to Treatment". The clock starts when a referral is received by a hospital for consultant-led care, and stops when treatment starts (or when it's clinically agreed that no treatment is needed). The 18-week operational standard says that 92% of incomplete pathways should be within 18 weeks at any given time — though performance against this varies hugely by specialty and trust.

Who the standard applies to
- NHS patients in England (Scotland, Wales and Northern Ireland have their own targets).
- Referrals for consultant-led, non-urgent care.
- It does not, in the same form, apply to: dentistry, maternity, mental health crisis pathways, or screening.
Exceptions and caveats
There are situations where waiting beyond 18 weeks is clinically appropriate, or where the clock pauses. The most common are:
- Clinical reason — e.g. you need other treatment first, or the optimal time is later.
- Patient choice to wait — you decide to delay for personal reasons (a holiday, work, family).
- Did not attend (DNA) — missing appointments can affect the clock.
- Specialised services — some highly specialised pathways have different timing.
Realistic expectations
It's important to be honest: passing the 18-week point doesn't trigger an automatic intervention. No one is alerted; no clinician is told to drop other patients to see you. You may need to be the person who picks up the phone. The standard exists to give you a basis for asking — not to get you an appointment by itself.
What you can reasonably ask for
- Confirmation of where you are on the pathway, and the expected next step.
- Whether your referral category should be reviewed in light of any new symptoms.
- Whether you can be added to a short-notice or cancellation list.
- A re-referral to an alternative NHS or NHS-funded provider with a shorter wait, under patient choice.
- An explanation in writing if there is a clinical reason your treatment is appropriately delayed.
PALS and the ICB escalation path
Your first port of call is usually the hospital's Patient Advice and Liaison Service (PALS). They sit between patients and the trust and can resolve a lot of problems informally.
If PALS can't help, the next step is the trust's formal complaints process. Above that sits your Integrated Care Board (ICB) — the local NHS body responsible for commissioning services in your area. ICBs handle complaints about primary care and have oversight of local provider performance. Beyond the ICB, the Parliamentary and Health Service Ombudsman is the final independent step.

Frequently asked questions
Is the 18-week target a legal right?+
It is a 'right' set out in the NHS Constitution for England, but it is described as an operational standard rather than an absolute legal entitlement. The Constitution itself notes the standard, and that you can ask to be referred to an alternative provider if it isn't met for non-urgent care.
What counts as 'starting treatment'?+
RTT treatment 'start' usually means the point at which a definitive treatment begins — for example surgery, the start of a course of therapy, or in some cases the decision that treatment isn't needed. A first outpatient appointment alone usually doesn't count as the clock stopping.
Can my clock be paused?+
There are some situations where the clock pauses — for example if you choose to delay treatment for personal reasons, or if you don't attend appointments. Trusts should explain this if it applies to you.
Do I have to accept a transfer to another hospital?+
No. If you've passed the 18-week point you can ask to be referred elsewhere, but you're not obliged to. Many people decide it depends on the consultant, hospital reputation, travel and how much longer they'd otherwise wait.
Can I claim compensation for a long wait?+
Generally no — the 18-week standard does not, on its own, create a right to financial compensation. If you've suffered direct clinical harm because of a delay, that's a different matter and you should speak to a regulated solicitor.
