Primary Health Need: The Legal Test Behind Every CHC Decision

Every NHS Continuing Healthcare decision turns on a single legal test — yet that test has no statutory definition. The phrase "primary health need" appears in the 2022 National Framework, in section 22 of the Care Act 2014, and in dozens of ICB policy documents. But the actual content of the test comes from a 1999 Court of Appeal judgment most families have never heard of.

NHS Birmingham & Solihull ICB confirms openly that "there is no legal definition of what constitutes a primary health need" (Birmingham & Solihull ICB, 2026). That gap between named and defined is where most families lose cases. This guide explains what the test actually is, where it comes from, how the courts and the Ombudsman have interpreted it, and where families can challenge a wrong application.

Reviewed by legal professionals and social care professionals.

TL;DR: "Primary health need" is the single legal test deciding whether the NHS or a local authority must fund care. It has no statutory definition — the Court of Appeal set it in R v North & East Devon HA, ex parte Coughlan [1999] EWCA Civ 1871 at paragraph 30(e). No diagnosis automatically qualifies. The Parliamentary and Health Service Ombudsman reviewed 336 CHC complaints (April 2018–July 2020) and found CCGs "misinterpreting and misapplying" the Framework (PHSO, 2020).

What is a primary health need?

A person has a primary health need when the main part of the care they require is for health rather than for social support or accommodation. The test decides who must pay: if the test is met, the NHS funds the full package; if not, the local authority arranges and means-tests care (DHSC National Framework, paragraph 56). There is no statutory definition of the phrase itself.

The test does one specific job. It decides which public body pays for someone's care — not whether care is needed, not how much care, not what type. Need is established separately. The primary-health-need test is the funding switch.

That switch is named everywhere and defined nowhere. NHS Birmingham & Solihull ICB confirms openly that "there is no legal definition of what constitutes a primary health need." The 2022 National Framework attempts an operational articulation through four key characteristics — nature, intensity, complexity, unpredictability — but those are indicators, not the test itself. The test sits underneath them.

The consequence matters. Because the test asks about needs, not diagnoses, no condition — dementia, Parkinson's, stroke, motor neurone disease — automatically qualifies. For more on how the four indicators connect to this underlying test, see our deeper guide to the CHC funding criteria the National Framework uses.

Where the test comes from — Coughlan (1999)

The legal test was set by the Court of Appeal on 16 July 1999 in R v North & East Devon HA, ex parte Coughlan [1999] EWCA Civ 1871 (BAILII). Pamela Coughlan, paralysed in a 1971 road accident, had been promised long-stay NHS nursing care "for as long as she chose." The health authority later tried to move her to means-tested local authority residential care. The Court of Appeal ruled the move unlawful.

The statutory frame was old but unchanged in substance. Section 21 of the National Assistance Act 1948 placed a duty on local authorities to arrange accommodation for those needing it. Section 1 of the NHS Act 1977 (now section 1 of the NHS Act 2006) placed a comprehensive duty on the Secretary of State to provide health services. The question the Court answered was where the line falls between the two.

The Court found the line. A local authority's lawful provision of nursing care is strictly limited — and where that limit sits is the primary-health-need test. Pamela Coughlan's nursing needs were not "merely incidental" to her accommodation; the NHS had to pay.

Why this case became the bedrock of CHC

Every National Framework since — 2007, 2009, 2012, 2018, and the current 2022 version — has been built on Coughlan. The Framework's own text refers to "the Coughlan principles" as the test the multidisciplinary team must apply. Twenty-seven years on, families challenging refusals still cite the same paragraphs. The judgment is the bedrock; everything else is operational guidance for applying it.

The two-limb test — "merely incidental or ancillary"

The Court of Appeal at paragraph 30(e) of Coughlan held that a local authority can lawfully provide nursing care only where it is (a) "merely incidental or ancillary" to the accommodation it has a duty to provide, and (b) "of a nature which it can be expected" social services would provide (BAILII). Two limbs: quantity (incidental) and quality (the kind of care).

Limb 1 — quantity. A lot of nursing care is not "merely incidental" to accommodation. If a person needs hourly skilled interventions through the day and overnight monitoring, the nursing isn't a side-effect of needing somewhere to live. It's the main thing. The local authority cannot lawfully take responsibility.

Limb 2 — quality. Some interventions are simply not the kind of care social services can be expected to provide. Skilled clinical management of pressure damage, dysphagia, complex medication regimes, and unpredictable behaviours that need clinical de-escalation all fall outside the social-services boundary. Both limbs need to be considered; either limb on its own can take the case off the local authority.

That formulation is now codified in statute. Section 22 of the Care Act 2014 lifts the Coughlan wording verbatim into the boundary clause separating local authority care from NHS responsibility. The phrase the Court of Appeal coined in 1999 is now in primary legislation — and it sits at the centre of every CHC decision in 2026.

What Grogan (2006) added — the test must be reasoned

In R (Grogan) v Bexley NHS Care Trust [2006] EWHC 44 (Admin) (BAILII), Mr Justice Charles ruled that decision-makers must actually apply a primary-health-need test with reasons — not simply assert that needs are "not complex" or "not severe." Bexley's published eligibility criteria failed because they offered no guidance on how the Coughlan test should be weighed.

The High Court remitted the decision. The trust had to re-assess Mrs Grogan with proper reasoning — not just a different conclusion, but a reasoned process for reaching one. The ruling stands for a simple proposition: assertion is not application. A decision letter that asserts "the needs are not severe enough" without engaging the Coughlan limbs is legally vulnerable.

That matters in 2026 because so many decision letters still rely on label-language. "Needs were not complex." "Care was routine." "Needs were well-managed." These are conclusions, not analysis. Grogan is the precedent families use when challenging conclusory refusals. For the appeal routes that flow from this, see our guide to how to challenge a CHC decision.

How the test is misapplied — what the Ombudsman found

In November 2020 the Parliamentary and Health Service Ombudsman published Continuing Healthcare: Getting it Right First Time (PHSO, 2020) after reviewing 336 CHC complaints between April 2018 and July 2020. The Ombudsman found CCGs were "misinterpreting and misapplying" the National Framework — in some published cases requiring redress of more than £250,000.

The PHSO identified three recurring failure patterns. First, decision-makers not understanding the legal test — applying the four indicators as a scoresheet rather than as evidence engaging the Coughlan limbs. Second, decisions lacking reasons — the Grogan problem still alive twelve years later. Third, needs being aggregated into the wrong domain so the complexity-and-unpredictability picture gets smoothed away.

Connect those three patterns and one thread emerges. Every PHSO failure pattern is a primary-health-need test that wasn't applied to the needs — only to the labels. The test asks about needs; the labels describe care provided. They are not the same thing, and treating them as the same is what produces refusals that don't survive review.

The headline trend: standard CHC eligibility fell from 27% in mid-2017 to 21% in Q4 2023-24 (Nuffield Trust, June 2024). At first review, about 13% of local resolution requests end with eligibility granted — roughly one in eight ICB decisions overturned on the same evidence, simply re-examined. The legal test hasn't moved. The application has. For the broader context, see the Healthwatch evidence on the falling eligibility rate and our coverage of ICBs cutting CHC eligibility.

Why diagnosis alone doesn't determine a primary health need

Related searches around "primary health need" are dominated by diagnosis questions — is dementia, Parkinson's, stroke, or Alzheimer's a primary health need? The legal answer is the same for all of them: no diagnosis automatically qualifies. The test is about needs, not labels. But each diagnosis tends to produce a recognisable pattern of needs that the test can engage with.

Is dementia a primary health need?

Not automatically. Severe dementia frequently produces a primary health need — when behaviour, cognition, communication, and unpredictability combine, the four key characteristics are typically engaged. Mild or early-stage dementia usually does not. The test looks at the care the dementia requires, not the diagnosis itself. The National Framework explicitly disallows diagnosis-led decisions.

Is Parkinson's a primary health need?

Same answer: not automatically. Late-stage Parkinson's involves motor, cognitive, swallowing, postural, and autonomic features that interact unpredictably — a strong fit with the test's complexity and unpredictability limbs. Earlier stages, where social care can reasonably support daily living, will not satisfy the Coughlan two-limb test.

Is a stroke a primary health need?

A stroke is an event, not a condition. The question is whether the post-stroke needs — communication, swallowing, mobility, behaviour, continence — together meet the primary-health-need test. Many stroke survivors with significant deficits do; many with social-care-only needs do not. The Decision Support Tool maps these needs across 12 domains.

What conditions automatically qualify?

None. The 2022 National Framework explicitly states no diagnosis automatically qualifies for CHC. The closest the system comes to automaticity is the Fast Track Pathway — for people with a rapidly deteriorating condition entering a terminal phase. Fast Track is a separate route that bypasses the standard Checklist and full assessment.

How to frame evidence in the test's language

Most refused families have evidence that would satisfy the Coughlan test — but it sits in the records in the wrong language. Care records describe the care provided; the test asks about the needs requiring care. Assessors score needs. So families must present needs. The shift from "what we do for Mum each day" to "what Mum would need if no one were there" is the single most important reframing in an evidence pack.

This is the well-managed needs trap. Records under-state needs by definition — they describe interventions, not the underlying need without the intervention. A pressure area turned every two hours by skilled staff shows up in records as "skin intact." The need is invisible because the management worked. The National Framework directly addresses this at paragraph 162: well-managed needs must still be counted when scoring.

What does reframing look like in practice? The four key indicators each map back to Coughlan's two limbs. The table below shows the mapping the assessor is making — whether explicitly or not — every time they score a domain.

If evidence is presented as four pictures of need, each tracking back to the legal limbs they engage, the assessor can apply the test. If evidence is presented as a list of tasks, they can't.

What this means in 2026

Primary health need is not a phrase from a policy document. It is a legal test set by a Court of Appeal in 1999, codified by Parliament in 2014, and still — twenty-seven years on — the single line every CHC decision turns on. Three things follow:

• The test sits underneath the indicators. The four key characteristics are how it gets applied. The Coughlan limbs are the test itself.
• No diagnosis automatically engages it. Dementia, Parkinson's, stroke, motor neurone disease — the test runs on needs, not labels.
• Refusals that don't reason against the limbs are legally fragile. Grogan established this in 2006; the PHSO confirmed it was still happening in 2020.

If you're at the start of the process, see our guide to the CHC funding criteria the National Framework uses and our family-side decision tree on who qualifies for CHC funding. For the screening tool itself, see our CHC Checklist guide. For the funding mechanics — what CHC pays for, the four delivery models, top-up rules and retrospective PUPoC claims — see our continuing healthcare funding family guide. If you've been refused, our free Eligibility Screener is the fastest way to triage whether the test was applied properly to your evidence.
