The state of Welsh NHS waiting lists ahead of the 2026 Senedd election
Wales goes to the polls on 7 May 2026, and the condition of the Welsh NHS has dominated the campaign. Thursday 23 April will bring the final official health statistics before election day, and the BBC's analysis suggests the Welsh government's key pre-election waiting list targets are likely to be missed. That timing matters: for weeks, Labour, Plaid Cymru, the Conservatives, Reform, the Lib Dems and the Greens have all been trading blows over who can fix the health service fastest, but the hard numbers will now land with just two weeks to go before voters make their choice.
The targets were set out by Health Secretary Jeremy Miles in April 2025 with considerable fanfare. He promised to cut waiting lists by 200,000, eliminate waits of two years or more, and ensure nobody waits more than eight weeks for diagnostic tests. Backed by £120m of additional funding, these were described as the government's "number one priority" in health. Yet the BBC Wales analysis shows that, despite eight consecutive months of falling overall waiting lists, the scale of the challenge remains daunting.
In January 2026, the waiting list stood at 713,048 patient pathways, a record monthly fall of 28,000. But to hit the 200,000 reduction target by March 2026, the Welsh NHS would need to achieve an even larger single-month reduction than it has ever managed before. That would be a historic first, and it is not expected to happen. This is the uncomfortable reality facing Labour as it seeks a fifth consecutive term in government.
Jeremy Miles' 2025 promises and the gap that has opened up
When Miles addressed health leaders in April last year, he framed the waiting lists pledge as an achievable, measurable goal. The £120m injection was meant to fund more outpatient appointments, diagnostic tests, and treatments, including more than 20,000 cataract operations. The direction of travel was positive, and the government was keen to point out that the overall list had been shrinking for months.
But the detail tells a more complicated story. At the start of 2026, more than 48,000 cases involved a wait of longer than eight weeks for diagnostic tests. That is actually 10,000 more than when Miles set his target of reducing that number to zero. The gap is not closing; it is widening, at least on diagnostics. Meanwhile, the pledge to eliminate two-year waits entirely has been publicly acknowledged as unlikely to be met across the whole of Wales.
One of the most striking elements is the decision, made last autumn, to start publishing provisional data alongside official statistics. Opposition parties immediately claimed the Labour government was trying to make itself look better before the election. The government rejected that charge, with Miles arguing that giving people as much information as possible was the "right approach". There is a practical argument here: official data has a seven-week lag, which would have meant the final pre-election snapshot would not arrive until after polling day. Publishing provisional figures at least gives voters some late insight, even if the spin is obvious to everyone.
The north Wales problem
Any honest assessment of the waiting list targets has to confront the regional divide. About 69% of the Welsh total of two-year-or-more waits are in the Betsi Cadwaladr University Health Board area. Swansea Bay, by contrast, has nobody waiting that long. Last autumn, the boss of NHS Wales admitted that problems "in the north of the country" meant the two-year target was unlikely to be met in all parts of Wales.
This is not a small footnote. It reflects deep structural issues in how health services are planned and delivered in north Wales, where rural geography, workforce shortages, and historical underinvestment combine to create a stubborn backlog. The Welsh government can point to national improvements, but voters in the north will experience this failure directly. It is hardly a surprise that the NHS is consistently in the top three issues that matter most to Welsh voters; for people waiting years for treatment, this is not an abstraction.
Party manifestos: how each party plans to fix the Welsh NHS
With the election just over two weeks away, the manifestos are now on the table. Labour says it would meet the 26-week waiting time target by the end of the next Senedd term and is proposing a £4bn hospital building programme. The Conservatives have pledged to declare a "health emergency" to focus resources on the service, with the aim of clearing waiting time backlogs by 2030.
Plaid Cymru has promised to deliver 10 new surgical hubs. Leader Rhun ap Iorwerth has said he would like to eradicate waits of more than two years within 12 months of taking office, and bring the overall waiting list down to pre-pandemic levels by the end of the parliament. The party has also faced scrutiny over its wider spending commitments, including 20 hours of free childcare a week for children aged nine months to four years old, and an existing pledge to provide 30 hours a week for three and four year olds whose parents are in work, education or training.
On BBC Radio Wales Breakfast on 23 April, ap Iorwerth said he was "confident that the sums add up", arguing that Plaid would "reprioritise" the budget and "spend money differently". He urged people to judge his party "not on how much we spend, but on what we achieve". Labour's response was pointed: "Plaid need to be honest with voters on how they will pay for their promises." Reform UK's leader in Wales, Dan Thomas, called the Plaid manifesto "a work of fiction", while the Welsh Conservatives said simply claiming the sums add up is not enough.
The other parties have their own ideas. Reform says it would launch a comprehensive emergency action plan involving an expansion of surgical hubs. The Lib Dems want to spend an extra £300m on social care to ease pressure on the NHS, and would be prepared to put a penny on income tax to pay for it. The Greens say investment should shift into prevention and primary care, rather than focusing so heavily on acute hospitals.
The bigger picture: a pattern of missed targets and an accountability vacuum
Stepping back, the current situation fits a longer and rather worrying pattern. Labour has previously faced criticism for failing to hit targets set out in its April 2022 Covid recovery plan. That plan was meant to get the NHS back on track after the pandemic; it did not fully deliver. Now another set of high-profile targets looks set to be missed, even as the most basic measure, the overall waiting list, is slowly improving.
What is the underlying problem? Wales spends more than half of its approximate £28bn budget on health and social care, yet outcomes continue to lag. This is not simply a question of money. It is about how the system is organised, how political leaders set expectations, and how they manage the gap between promise and delivery. The decision to publish provisional data, whatever its merits, also tells us something about the election calendar: the government wanted its best possible numbers out before voters went to the polls. That is standard political behaviour, but it does not inspire confidence in the long-term planning of the NHS.
There is a wider lesson here for UK political culture. Across the four nations, health services are struggling with waiting lists, workforce shortages, and the lingering effects of the pandemic. Wales shows what happens when targets are used as political weapons rather than as genuine management tools. A target that is set with no realistic plan to achieve it becomes a liability, not a motivator. The next Welsh government, whatever its colour, will inherit a falling waiting list that is still far higher than it was before the pandemic, and a public that is deeply sceptical of political promises.
What Thursday's figures mean for the campaign's final stretch
Thursday's data will not be read in a vacuum. Every party will use it to reinforce its central narrative. Labour will point to eight consecutive months of falling lists and argue that the recovery is underway, even if specific targets were missed. The opposition parties will seize on the same numbers to say that 27 years of Labour in power has failed to deliver a functioning NHS. The truth, as ever, sits awkwardly in between: there is genuine progress, but it is too slow and too uneven for the people still waiting years for treatment.
For voters, the key question is not just which party has the best diagnosis, but which party is most honest about the scale of the challenge. The 2026 election has seen parties make bold promises about surgical hubs, hospital building, and waiting time guarantees. None of them has published a detailed set of costings during the campaign. Plaid Cymru has insisted its childcare pledge is fully funded, but has not said what it would cut. Labour's £4bn hospital programme sounds ambitious, but there is no independent scrutiny of how it would be financed within the existing budget.
In the end, the Welsh NHS waiting lists story is not merely a stats release. It is a test of political credibility. The people of Wales will vote on 7 May with their own experiences of the health service front of mind. The next government will have to do more than promise; it will have to deliver. And on the evidence of the last few years, that will require a far more honest conversation about money, capacity, and the limits of what any single Senedd term can achieve.
