A77Delivery risk: AmberGate: pending
Make heat protection operational in vulnerable settings
Existing action A77, assessed at the same scope.
Provisional single-reviewer desk assessment, 6 October 2026.
- Who and where
- Residents of existing care homes in England, starting with homes assessed at highest overheating risk. (from the action record) Jurisdiction: England.
- Result so far
- Range if completed: 17.0–23.0 out of 30 (equal weights; not yet assessed: expected incremental benefit (Bn), incremental affordability (Co))
- Funded now (baseline)
- Baseline: the Adverse Weather and Health Plan (guidance; no statutory duty or indoor-temperature standard for care homes); building regulations on overheating (Approved Document O) for new buildings only; more than £32m for NHS cooling projects (September 2026), nothing yet for social care. Risk assessment and building-specific measures in existing care homes is a UK Facts proposal, not government policy. (from the action record)
- The change assessed (marginal)
- Assess overheating in selected care settings and homes, then commission proportionate cooling, shading and response plans. (from the 6 October review)
- Domain home: Social care
- In the national plan: Resilience and sustainability appraisal queue
What the evidence supports—and the next decision
Heat-associated mortality establishes a risk, not the causal effect of a local adaptation package.
AI-assisted analytical follow-up · 8 October 2026. Proposed appraisal design; the attributed scores below are unchanged. No funding or delivery agreement is implied.
- Define the change
- Assess overheating in specified care settings or homes; compare shading, ventilation, cooling and operational response options.
- Test whether it works
- Indoor exposure, implementation of response plans and health outcomes adjusted for weather, resident vulnerability and occupancy.
- Establish the cost
- Assessment, capital works, energy, maintenance, staffing and replacement; test hotter summers and power interruption.
- Protect against harm
- Protect frail residents, air quality and clinical safety; avoid interpreting a mild summer as success.
Read with the outcome evidence and sources in the full assessment. Monitoring proposals are not existing baseline measurements. A numerical benefit or cost score needs evidence for the defined increment, not just the scale of the problem.
Full assessment of Make heat protection operational in vulnerable settings: ten criteria, scenarios, delivery, costs and monitoring
The ten criteria (0–3)
Each criterion is scored 0 to 3 by the reviewer. “Not yet assessed” means unknown: it is never counted as zero.
Scale and severity (Sc)3 of 3 — Severe harm across a broad population
Reviewer’s reason: Problem scale judged from the linked domain evidence; not a population estimate of those helped.
Increment beyond baseline (Ad)2 of 3 — Specific material change to existing delivery
Reviewer’s reason: Assess overheating in selected care settings and homes, then commission proportionate cooling, shading and response plans. This is a provisional marginal-change judgement, to confirm against commissioned delivery.
Confidence in the proposed action (Ev)0 of 3 — No effect evaluation
Reviewer’s reason: The site records heat risk and options; it does not evaluate this exact package.
Expected incremental benefit (Bn)Not yet assessed
Reviewer’s reason: Unknown: no sufficiently supported magnitude for this exact change.
Residual harms (Hm)2 of 3 — Manageable harm with specified safeguards
Reviewer’s reason: Energy costs, unsuitable retrofits and staff workload.
Incremental affordability (Co)Not yet assessed
Reviewer’s reason: Unknown: the proposed increment has not been costed and matched to an approved affordable allocation in this review. Existing programme envelopes are not that allocation.
Delivery capacity (Ca)2 of 3 — Stretched but plausibly obtainable
Reviewer’s reason: Use risk-based standards; a mild summer is not proof the intervention worked.
Distribution (Fa)3 of 3 — Benefits concentrated on disadvantaged people with assessed burdens
Reviewer’s reason: Distribution assessed against the target group and the burdens described here: Energy costs, unsuitable retrofits and staff workload.
Meaningful first outcome (Ti)3 of 3 — Within one year
Reviewer’s reason: Timing judgement concerns the first meaningful outcome in: Indoor exposure, response readiness and heat-related harm with weather-adjusted interpretation. It does not imply all long-term benefits arrive then.
Readiness (Rd)2 of 3 — Named commissioning/allocation/coordination step
Reviewer’s reason: Cost a local risk-led plan before the next warm season, prioritising people unable to protect themselves. Owner: Health/care providers, councils and landlords with public-health advice.
Four weightings
Normalised as 10 × weighted sum ÷ sum of weights, on a 0–30 scale. Where a criterion is not yet assessed, the range is the lowest and highest result if it were later scored 0 or 3 — not a score, a confidence interval or a rank.
- Equal weights: Range if completed: 17.0–23.0 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
- Evidence doubled: Range if completed: 15.5–20.9 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
- Scale doubled: Range if completed: 18.2–23.6 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
- Cost ignored (the funding gate still applies): Range if completed: 18.9–22.2 out of 30. Not yet assessed: expected incremental benefit (Bn), incremental affordability (Co). Funding gate: not passed.
Funding gate: Not passed — the cost is not yet assessed or no allocation is committed for this scope. Ignoring cost in a weighting never removes the gate.
Delivery risk and gate
Delivery risk shown: AmberReview’s claim: Amber. Best the recorded evidence allows: Amber.
Review’s reason: Incremental lifetime costs and funding not established. Use risk-based standards; a mild summer is not proof the intervention worked.
Why it is not Green yet
- Scope (population, place and increment) not verified against the delivery baseline.
- No verified owner with the powers in place.
- Delivery capacity not verified.
- Lifetime incremental costs not complete.
- No credible funding (a committed allocation for the scope).
- Safeguards not specified.
- Monitoring lacks a metric, a data source or a baseline.
Green needs verified scope, a verified owner with the powers, verified capacity, complete lifetime costs with credible funding, specified safeguards and monitoring with a metric, source and baseline. Amber means appraisal gaps remain; Red means a material delivery obstacle. Red does not mean unimportant.
Gate: Pending — appraisal incomplete (review label: “Pending cost, funding, scope and capacity appraisal”).
Why: Scores incomplete; Funding gate not passed (cost unknown or no credible funding).
The gate is separate from national list membership: being listed does not make an option eligible, and an eligible option need not be listed.
Cost and funding
Lifetime costing: Not established.
Still to cost: Incremental lifetime costs and funding not established. Use risk-based standards; a mild summer is not proof the intervention worked.
Funding status: not identified.
Owner, powers and capacity
Proposed owner: Health/care providers, councils and landlords with public-health advice. (proposed, unverified).
Powers: needs a decision or allocation. Capacity: unverified.
Powers and capacity read from the review’s Rd and Ca anchors; no proposed owner has agreed to act (the review: “Proposed owners have not agreed to act”).
- England:
- Department of Health and Social Care with UKHSA, the care regulator, councils and care providers (action record)
- Scotland:
- not assessed
- Wales:
- not assessed
- Northern Ireland:
- not assessed
Health, care and building rules are devolved; not assessed outside England.
Dependencies, safeguards and risks
Depends on: Use risk-based standards; a mild summer is not proof the intervention worked.
Safeguards
- Cost a local risk-led plan before the next warm season, prioritising people unable to protect themselves (proposed, not yet specified)
Risks and residual harms: Energy costs, unsuitable retrofits and staff workload.
Monitoring and measured results
Metric: Indoor exposure, response readiness and heat-related harm with weather-adjusted interpretation.
Data source: Not yet named. Baseline: Not yet established.
Measures already on the domain page
- Heat-associated deaths in care homes: latest 677 (95% CI 406–949) (Summer 2025); baseline not published (England).
A page measure is not necessarily the review’s metric; linking the two is an editorial decision still to be made.
Evidence for the outcome
Outcome: Indoor exposure, response readiness and heat-related harm with weather-adjusted interpretation.
The site records heat risk and options; it does not evaluate this exact package.
SWOT points it addresses
- Care homes had more heat-associated deaths than any other setting in summer 2025 — an estimated 677 (95% CI 406–949), 9% above the expected level — and there is no routinely collected data on overheating or adaptation in care homes. (Social care)
- Hot summers already cost lives: UKHSA estimated 1,504 heat-associated deaths in England in summer 2025 (677 of them in care homes) and 2,985 in 2022, and an interim 2,877 in the May and June 2026 heatwaves alone; the Climate Change Committee warns heat-related deaths could exceed 10,000 in an average year by 2050 as the population ages.
