NHS minimum waits: which areas make you wait 12 to 16 weeks for cataract, hip and knee surgery
Reports read (Taipei time)
Short answer
NHS minimum waits are rules some health boards in England use to make patients wait a set time before planned surgery, even when a hospital has space. The BMJ asked all 36 integrated care boards (ICBs); 17 of the 35 that replied said they had one, of 12 to 16 weeks, for procedures including hip, knee and cataract surgery (BMJ Group). Another 17 said they had none, and NHS North East London could not say.

Which areas have NHS minimum waits
These are the boards The BMJ named, longest first. It reported 17 boards with a policy but named 14 in its release, so a board missing here may still have one: ask your GP or hospital.
The bar runs to 18 weeks, the NHS Constitution's referral-to-treatment standard. Source: The BMJ's Freedom of Information survey, as summarised in BMJ Group's press release of 9 September 2026.
Why boards set minimum waits, and what the NHS says
Some boards told The BMJ the waits let them make the best use of their money and treat patients fairly. NHS England said that commissioned wait policies help the NHS use its services, staff and budgets, that all patients are seen in order of clinical need, and that it would not expect any organisation to commission waits that risk breaching the NHS Constitution's 18-week maximum. The Royal College of Surgeons said it was “concerned by the scale”, and the Royal College of GPs called blanket minimum waits “difficult to justify” (BMJ Group).
For cataracts, Optometry Today reports that boards brought the waits in to manage elective activity and spending across the financial year, and that the wait was also described as a way to prioritise people at greater risk of losing sight (AOP).
Minimum waits for cataract surgery: what patients report
A report published on 29 October 2026 surveyed 520 people waiting for NHS cataract surgery between December 2025 to January 2026. 85% said their vision got worse while they waited; one in five had gone to A&E or needed treatment after a trip or fall. It estimates each week of delay costs £164 per patient in health, care and economic value, more than £400 million a year in England (Optometry Today).
Who paid for it: the report was commissioned by SpaMedica, an independent provider of cataract surgery, which is asking boards to pause minimum waits. Read its estimates with that in mind. The list of boards above comes from The BMJ's own survey, not from SpaMedica.
Your rights while you wait
- The 18-week right still applies. You have a right to start consultant-led treatment within 18 weeks of referral for non-urgent conditions; if that is not possible, your ICB or NHS England must take all reasonable steps to offer a suitable alternative provider (NHS Constitution handbook). A minimum wait of up to 16 weeks sits inside that limit.
- Clinical need comes first. NHS England says patients are seen in order of clinical need; if your sight, pain or mobility gets worse, tell your GP or hospital so they can review your priority.
- Ask for your date. Ask the hospital which rule your board uses and when you can expect treatment, in writing.

If you do not want to wait: UK private and abroad
The waits at home and the price of not waiting, for the three operations the minimum waits hit most. Prices are the lowest each provider publishes; the trip adds a rough return flight and hotel.
NHS England figures are for the whole specialty (all eye care, all orthopaedics), not one operation. The flight and hotel are rough estimates, not quotes.
The NHS S2 route pays for state treatment in Europe only when the NHS cannot treat you in a medically acceptable time, with approval first, so ask NHS England whether a minimum wait would count before you plan around it. See S2 funding route: when the NHS pays for treatment abroad.
NHS minimum waits: questions
What is an NHS minimum waiting time?
A rule set by an integrated care board (ICB), the body that buys NHS care for an area, that patients wait at least a set time before planned treatment, even when a hospital could treat them sooner. The BMJ found 17 of 36 boards in England using one, of 12 to 16 weeks.
Which areas have a 16-week minimum wait?
The BMJ named 4: Shropshire, Telford and Wrekin (all routine procedures), West Yorkshire (all routine procedures), South East London (cataract surgery), Humber and North Yorkshire (an average-wait planning assumption).
Is there a minimum wait for cataract surgery?
In some areas. South East London has a 16-week minimum wait for cataract treatment and Thames Valley a 14-week one, and several boards apply 14 to 16 weeks to all planned procedures, which includes cataracts. Ask your GP or optician which rule your ICB uses.
Is there a minimum wait for hip or knee replacement?
Where a board applies its minimum wait to all routine or elective procedures, hip and knee replacements are included; Leicester, Leicestershire and Rutland applies 14 weeks to orthopaedics specifically. The BMJ did not name every board with a policy.
Do minimum waits break the 18-week rule?
Not by themselves: 16 weeks is shorter than 18. Experts quoted by The BMJ warn that blanket 16-week waits risk breaching the NHS Constitution’s 18-week referral-to-treatment standard, which has not been met nationally since February 2016. NHS England says it would not expect any organisation to commission waits that risk breaching those standards.
Can I avoid an NHS minimum wait?
Within the NHS, ask your GP or hospital whether your ICB has a minimum wait for your operation and what your expected date is. Outside it, you can pay privately in the UK or abroad. The S2 route depends on the NHS being unable to treat you in a medically acceptable time and needs approval first, so ask NHS England before you count on it.
