Kent & Canterbury’s “temporary” stroke unit is now producing nationally impressive results. NHS bosses still want to move it to William Harvey Hospital in Ashford. The unanswered question is whether that’s safer, fairer — or value for money.
There’s a sentence in the latest Kent & Medway ICB papers that does a lot of heavy lifting. Kate Langford told the Board that two of the three planned hyper-acute stroke units were operational, with the third “temporarily located at Kent and Canterbury Hospital pending its permanent move to the William Harvey Hospital”. It sounds tidy. It isn’t. Behind that sentence sits an eight-year reconfiguration, a Covid emergency move, a high-performing Canterbury service, a £23.9m Ashford capital scheme, missing travel data, unanswered cost questions and a very live argument about Thanet, deprivation and time-critical care.
The official line is simple enough. Kent & Medway’s stroke reconfiguration was meant to replace six stretched acute stroke services with three specialist hyper-acute stroke units, at Darent Valley, Maidstone and William Harvey. The Independent Reconfiguration Panel recorded that the decision was taken in February 2019 after a consultation with about 5,000 responses, and that the clinical case for change was “well established and widely accepted”. The old model had real problems. Kent & Medway didn’t have proper HASUs, staffing was too thinly spread, and services were struggling to meet national standards.
Nobody should pretend the original case for change was nonsense. The 2019 Decision Making Business Case said the way stroke services were configured, alongside staff shortages, meant local hospitals didn’t regularly meet national SSNAP standards. It also said stroke services were running at an estimated £7.8m loss and that the area had “no hyper acute stroke units”. That’s a serious clinical and financial problem, not a minor management preference.
But then Covid arrived and the facts changed. In April 2020, East Kent Hospitals transferred stroke services from William Harvey Hospital and Queen Elizabeth The Queen Mother Hospital to Kent & Canterbury Hospital. The 2026 HOSC paper says this was done “in response to Covid” and that “the stroke service remains at Canterbury at this time”. A temporary emergency arrangement has now lasted six years. In NHS language, that’s temporary. In normal life, that’s long enough for a child to start school and learn joined-up handwriting.
The problem for the old business case is that Canterbury hasn’t failed. It’s done the opposite. NHS Kent & Medway’s April 2026 HOSC report says the temporary consolidation onto one East Kent site “has already transformed care for local people”. It says East Kent Hospitals was named the best-performing stroke service in the country in the latest SSNAP results published in January 2026. It says 97.2% of patients were scanned within one hour, compared with 62.7% nationally. It also says adjusted mortality had fallen, “saving around 65 lives each year”.
So this isn’t a story about moving a failing service. It’s a story about moving a service that official papers say is performing extremely well. That’s why the wording matters. The ICB says Kent & Canterbury “did not meet all clinical co-dependencies”, even though it was “supporting service continuity”. That may be clinically important. But it doesn’t answer the public’s simpler question: if Canterbury is saving lives and producing top-ranked results, why spend millions moving it again?
The money isn’t loose change. The 2026 HOSC paper says the full business case for the William Harvey unit was approved in November 2025 and that the East Kent scheme is funded from a £23.9m capital allocation, covering the full design and construction cost of the unit. The wider three-HASU programme totals more than £32m. Yet the same report says revenue requirements are still being reviewed and expected “in the coming months”. In other words, the building-cost figure is public. The full running-cost picture still isn’t.
That matters even more because the ICB’s own 2026/27 financial plan is tight. The Board papers say Kent & Medway ICB approved a deficit plan of £50.8m with an efficiency requirement of £79.7m. This is the financial weather in which the stroke move is being pushed forward. When a system is trying to save tens of millions, value for money stops being a polite committee phrase and becomes the whole story.
There’s another missing number: what did it cost to move the East Kent stroke service to Canterbury in 2020? Public papers explain why it happened. They show it produced strong outcomes. But they don’t appear to publish a clean, itemised cost for the emergency move: estate works, staffing, digital changes, ambulance implications, project support, double-running or recurrent consequences. If the NHS is now asking the public to accept another move in the opposite direction, the first question is obvious: what did the last move cost?
The NHS’s strongest argument for Ashford is co-location. The William Harvey unit is planned as a purpose-built facility on an acute hospital site, with direct ambulance access, triage and assessment bays and CT scanning inside the unit. That’s not trivial. Stroke is time-critical, and a properly designed HASU next to the right acute services can be a powerful clinical model.
But the scrutiny record contains the awkward line. At HOSC, Dr Langford said she expected “equivalent patient outcomes” at William Harvey compared with the current Kent & Canterbury service. Members then raised concern that the relocation was expected to achieve “equivalent, not improved, outcomes”, while the Canterbury unit was already performing very well and public funds were limited. That’s the value-for-money issue in one sentence. If the expected outcome is equivalent, what exactly is the £23.9m buying?
Then comes Thanet. The IRP accepted that the NHS had adopted a 120-minute “call to needle” standard and used 60 minutes’ travel time as a proxy. It also noted that under all options the proxy wasn’t achieved “by a few minutes” for a small part of the population, notably north-east Thanet patients going to William Harvey. The official answer was that faster treatment after arrival could offset longer journeys. That may work clinically. But it needs proving against today’s roads, today’s ambulance pressures and today’s Canterbury performance.
The April HOSC minutes expose the gap. Members were told ambulance journey times from Thanet to William Harvey for the angioplasty service had ranged from 33 to 56 minutes over the previous year. But “the comparable blue light times for the stroke service at KCH were not available”. Members were also told “call to needle times were available but had not been provided for this report”. That isn’t good enough. If the whole argument turns on time saved in hospital outweighing time lost on the road, the actual times should be on the table.
SECAmb’s own figures add useful context. The ambulance trust says Category 2 calls include serious conditions such as suspected stroke, and reported an average Category 2 response time of 27 minutes and 46 seconds for 2025/26. Put that beside the 33 to 56-minute Thanet-to-William-Harvey journey range and you’re already at roughly 61 to 84 minutes before adding call handling, time on scene, loading, traffic variation, hospital handover, scanning and treatment decision-making. That’s not a clinical model. It’s basic arithmetic showing why HOSC was right to demand proper modelling.
SONIK warned years ago that Kent’s geography couldn’t be treated like London’s. Its 2019 critique argued that the London HASU model couldn’t simply be lifted and dropped onto Kent because longer rural and coastal travel times made centralisation harder. Whether one agrees with every campaign point or not, that concern now looks sharper, not weaker. The Isle of Thanet News has also tracked local anxiety, including Cllr Karen Constantine’s question in 2023 about why the service couldn’t remain at Canterbury, where it was already being delivered.
The thrombectomy position makes the story even more complicated. The ICB minutes say mechanical thrombectomy is a specialist service commissioned separately, currently based at Kent & Canterbury, and that non-co-location with the HASU is “common nationally”. But the ICB action log says the service hadn’t yet been able to run because of recruitment difficulties, was aiming to go live with a limited Monday-to-Friday 9am to 5pm service, and had no date for extending beyond those hours. For the most serious stroke patients, “not yet 24/7” isn’t small print.
There’s also a governance niggle. HOSC was told construction at William Harvey was expected to start on 1 June 2026, subject to planning permission, with opening expected in late 2027 or early 2028. Yet the ICB’s May 2026 action log still said Kate Langford’s action to clarify the planning application status for the permanent HASU at William Harvey was “Awaiting a response from EKHUFT”. That doesn’t prove anything dramatic. It does suggest the public timeline and internal action tracking weren’t fully joined up.
HOSC saw the problem clearly. Members were concerned about health inequalities, more deprived areas being disproportionately affected by increased travel distances, the current Canterbury unit’s strong performance, limited public money, the fact that the move was expected to produce equivalent rather than improved outcomes, and the age of the 2018 evidence. They asked for Canterbury to be retained as the permanent East Kent HASU, further clear evidence supporting William Harvey, a full updated Equality Impact Assessment focused on Thanet and coastal East Kent, side-by-side modelling, independent assessment of travel times and ambulance resilience, and justification for why the existing high-performing service couldn’t be retained.
That is the evidence checklist. It isn’t anti-NHS. It’s pro-public accountability. The NHS may yet prove that William Harvey is the right long-term answer. A purpose-built unit on an acute site with the right clinical co-dependencies could be the best model. But the burden of proof has shifted. It’s no longer enough to say Canterbury was temporary. The temporary service is now the high-performing reality. The permanent plan needs to beat that reality with evidence, not just history.
So the question remains. What did it cost to move the service to Canterbury in 2020? What will it cost, in full, to move it back to Ashford? What would it cost to keep and upgrade Canterbury? Where’s the latest Equality Impact Assessment? Where are the Thanet-specific call-to-needle times? Where are the comparable blue-light times to Canterbury? What’s the ambulance resilience model? And if Ashford is expected to deliver equivalent outcomes, not better ones, what exactly are residents buying for £23.9m?
Until those answers are public, the story is painfully simple. East Kent’s stroke service was moved to Canterbury in an emergency. Canterbury then became a top-performing service. Now the NHS wants to move it back to Ashford at major capital cost, while key evidence on travel, equality, cost and thrombectomy availability remains incomplete in the public record. In management language, that’s a reconfiguration. In plain English, it looks like moving the furniture again while the house is still full of patients.
