How to interpret CQC inspection ratings

The Care Quality Commission (CQC) is the independent regulator of health and adult social care in England. Every NHS Trust, every GP practice, every adult social care provider, and every dentist that holds an NHS contract is inspected and rated by CQC inspectors. The rating you see on a Trust or GP profile is the result of a published inspection report.

The four rating bands

CQC uses a four-band scale. From best to worst:

Outstanding — the service performs exceptionally well; in the top tier nationally for the regulated activity.
Good — the service is performing well and meeting expectations.
Requires Improvement — the service is not performing as well as it should and CQC has told it how it must improve.
Inadequate — the service is performing badly; CQC may take enforcement action including special measures.

The five Key Questions (five-domain breakdown)

Each overall rating breaks down into five sub-domains, each individually rated on the same four-band scale:

Safe — protected from abuse and avoidable harm.
Effective — care, treatment, and support achieves good outcomes and promotes a good quality of life.
Caring — staff involve, treat people with compassion, kindness, dignity, and respect.
Responsive — services are organised to meet the needs of the people who use them.
Well-led — leadership, management, and governance assures high-quality care.

A Trust rated “Good” overall may still be rated “Requires Improvement” on Safe or Effective. The five-domain breakdown is the most useful detail to read — it is published in full in each Trust's official CQC inspection report.

Aggregate ratings for big Trusts

A large acute Trust spans multiple hospitals and many core services (e.g. urgent and emergency care, medical care, surgery, critical care, maternity, services for children and young people, end-of-life care, outpatients). Each core service is rated individually. The Trust's overall rating is the CQC's holistic judgment, not a simple average.

How recent the rating is

Every PlainNHS Trust and GP profile shows the inspection date. CQC publishes new inspection reports continuously; a rating older than 18-24 months should be checked against the underlying report on the CQC website (linked on every PlainNHS profile).

What CQC ratings do NOT measure

CQC ratings are a quality judgment based on inspection — they are not a measure of operational throughput (e.g. RTT waiting times or A&E 4-hour performance). A Trust can be CQC-rated “Outstanding” while operating at long elective waits, or rated “Requires Improvement” while delivering strong A&E performance. Both signals matter and PlainNHS shows them side by side on every Trust profile.

Common questions

Where can I find the official documentation? Each numbered source link above takes you to the canonical NHS England, NHS Digital, NICE, or CQC publication. PlainNHS does not paraphrase these documents at length — we point you to them and explain the practical implication for patients.

How often does the underlying guidance change? NHS operational standards (RTT, A&E, cancer) have been stable for several years but performance against them is published monthly. NICE guidelines are revised every 2-3 years on a published schedule. CQC's inspection methodology was last updated in 2024 and the new framework is now in force for all inspections.

What if my situation differs from what is described here? Always speak to your GP, NHS 111, or PALS at the treating Trust. The guidance on this page covers the standard pathway; individual cases can vary on clinical grounds, locality of services, and patient preference.

How PlainNHS uses this guidance

When we present operational performance data on a Trust profile (e.g. “a Trust achieved 76% on the 18-week RTT standard”), we are referring to the same standard described on this page. Reading this guide gives you the context to interpret the numbers correctly. The PlainNHS methodology describes how we compute and verify the figures.
