Care Home Staffing Levels: Is There a Legal Ratio, What CQC Expects and How to Calculate Yours (2026)

Care Home Staffing Levels: Is There a Legal Ratio, What CQC Expects and How to Calculate Yours (2026)

The legal position on staffing ratios, what CQC inspectors look for, a method to calculate day and night staffing from residents’ needs and the records that prove it. For care home managers in England.

There is no legal staff-to-resident ratio for care homes in England. Regulation 18 requires “sufficient numbers of suitably qualified, competent, skilled and experienced persons” to meet people’s needs at all times. CQC expects a systematic approach: assess each person’s needs, work out the staff numbers and skill mix that meets them (day and night), review it continuously as needs change and keep records that show how you decided. Rules of thumb such as a set number of residents per carer are not CQC standards, and a rota that is “full” can still fall short of what people need.

This guide is for registered managers and providers of care homes in England, with notes for home care. It explains the legal position, what CQC’s guidance on Regulation 18 says, a practical method to calculate staffing from residents’ needs and the evidence inspectors look for. It draws on CQC’s Regulation 18 guidance and Skills for Care advice, linked in the sources section. Where a step is our suggestion rather than a CQC requirement, we say so.

Is there a legal staff-to-resident ratio in care homes?

No. The law gives no fixed ratio, and CQC does not publish one. Regulation 18 (Staffing) says sufficient numbers of suitably qualified, competent, skilled and experienced persons must be deployed to meet the requirements of the fundamental standards. CQC’s guidance explains the intention: enough staff to meet the needs of the people using the service at all times.

That is deliberate. A home supporting people with advanced dementia or nursing needs needs a different model from one with mostly low-dependency residents, so a single national number would be either too low for some homes or meaningless for others.

You will see older rules of thumb online, such as one carer for five residents in the morning, one for eight in the afternoon and one for ten at night. Some suppliers describe these as outdated pre-set ratios. They are not CQC standards, and an inspector will not accept “we meet the usual ratio” in place of evidence that staffing meets your residents’ needs.

What does CQC say about staffing levels?

CQC’s guidance on Regulation 18(1) says providers must:

• Deploy enough suitably qualified, competent, skilled and experienced staff to meet people’s care and treatment needs and the fundamental standards.
• Have a systematic approach to deciding the number of staff and range of skills needed to keep people safe at all times, reflecting current legislation and guidance. This should consider different levels of skills and competence, the registered professionals and support workers needed, supervision needs and leadership requirements.
• Review staffing levels and skill mix continuously and adapt them to people’s changing needs and circumstances.
• Have emergency procedures that make sure enough suitable people cover both the emergency and the routine work of the service.

Regulation 18 also covers support, training, supervision and appraisal for staff, which is why staffing and mandatory training are assessed together. CQC cannot prosecute for a breach of Regulation 18, but it can take other regulatory action, and must refuse registration if a provider cannot show it will comply. See Regulation 18 explained.

What decides how many staff you need?

What Skills for Care advises

Skills for Care, the workforce body for adult social care in England, draws on services rated Good and Outstanding. Its advice on deciding safe staffing levels includes:

• Safe staffing is about more than having enough people on duty: time for meaningful interaction, healthcare activities and training counts.
• There is no one-size-fits-all approach. The registered manager is responsible for regularly assessing staffing needs, adjusting and planning ahead.
• Include documentation, handovers, working with healthcare professionals, supervision and learning, not only shift numbers.
• Consider the environment: building layout in a care home, travel in home care.
• Use real data on turnover, leave, sickness and training, and allow for the effect of new, agency or bank staff on experienced colleagues’ time.
• Allow time for the personal side of care: activities, emotional support and one-to-one time.

How to calculate care home staffing levels: a step-by-step method

CQC does not prescribe a formula, so this is our suggested method, built from CQC’s “systematic approach” guidance. Use a recognised dependency tool if you have one and keep your own reasoning on record.

1. Assess dependency for every resident, covering mobility, continence, eating and drinking, cognition, behaviours, nursing needs and night-time needs. Review it whenever needs change.
2. Convert it to care time, using your dependency tool or your own timed observations, per resident and per shift. Include one-to-one time and activities.
3. Add the non-care work: handovers, documentation, medicines rounds, meals, laundry or kitchen work if done by care staff, supervision and training.
4. Total hours for day and for night separately. Needs are not spread evenly across 24 hours, so do not split a daily total by a fixed percentage.
5. Turn hours into staff. Divide by the hours in a shift to get the number of staff per shift, then check the skill mix: qualifications, medicines competence, seniority.
6. Add a buffer for sickness, absence and breaks, using your actual absence rates.
7. Roster to the result, and record any shift that runs below it, why, and what you did.
8. Review on triggers: a new admission, a deterioration, an incident pattern, a complaint or changes in call bell data.

Illustrative arithmetic (hypothetical figures, not a benchmark): suppose your assessments show 96 hours of care and support needed across the day shift hours and 60 hours across the night, including non-care work. With 12-hour shifts that is 8 staff on days and 5 on nights before any buffer for absence. Your numbers will differ, and what matters is that you can show where yours came from.

Day and night staffing

Most homes need fewer staff at night than during the day, but “fewer” must still be enough. Base the night figure on night-time needs: people who wake often, need repositioning, are at risk of falls, are distressed or need medicines or personal care. CQC reports often look at response times to call bells at night and whether staff can safely respond to two people at once. Check also that night staff have the skills for emergencies: first aid, evacuation and knowing who to call.

Nursing homes and skill mix

In a care home with nursing, the question is not only how many staff but whether the right registered professionals are on each shift for the nursing needs of residents. Regulation 18 refers to the registered professional and support workers needed, and requires that registered professionals be enabled to meet their regulator’s standards. Record the nursing hours you need, how they are covered and what happens when a nurse is absent.

Agency and bank staff

CQC does not mark a provider down for using agency or bank staff. Risks arise when use is high and unplanned, workers are not inducted or briefed on residents’ needs, or no permanent staff member with knowledge of the residents is on shift. Skills for Care notes that new and agency staff often need support from experienced colleagues, which lowers team productivity. Track agency use as a trend, keep a short induction checklist for every shift and record how continuity of care is protected. This is our suggestion rather than a CQC rule.

What inspectors look at for staffing

CQC gathers evidence from people, staff and records. For staffing, expect inspectors to:

• Ask people and families whether staff are available and how staffing affects their day.
• Observe whether call bells and requests are answered promptly, how handovers work and how staff are deployed.
• Speak to staff, including about nights and weekends and how gaps are covered.
• Look at rotas over time, dependency and staffing level assessments, agency records, incident and accident patterns, complaints and meeting minutes.
• Check recruitment files, training and supervision records.

The weak spot we see most often (our observation) is a rota that shows every shift “covered” while the dependency assessment says more is needed. If your assessment says four on a shift and the rota shows three, be ready to explain why. See also what evidence CQC inspectors look for.

Records that prove your staffing is safe

• Current dependency assessment for each resident, with review dates.
• The staffing calculation, with its date and who did it.
• Rotas showing planned and actual staff by shift, with qualifications.
• Notes on any shift below plan, the reason, the risk assessment and the action taken.
• Records of staffing reviews triggered by changes, with outcomes.
• Absence, turnover, vacancy and agency data, and recruitment progress.
• Training, induction and supervision records (see supervision frequency).
• Governance minutes showing staffing discussed and challenged (Regulation 17).

Specific beats vague. “Staffing is reviewed regularly” tells an inspector nothing, while “Dependency review on 3 September scored four residents as high dependency, up from two in July. Day shift increased from three to four carers from 5 September and was reviewed again on 3 October” shows your reasoning.

Home care agencies

Regulation 18 applies to home care too, but “enough staff” works differently: you must have enough trained staff to deliver every planned visit at the right time and for the right length, with realistic travel time. Skills for Care highlights the location of the people you support. Evidence includes visit schedules against actual visit times, missed or late visit logs, travel time assumptions, on-call arrangements and capacity checks before accepting new packages.

How staffing connects to other regulations

Staffing gaps are often the root cause of findings elsewhere: missed care under Regulation 12 (safe care and treatment), poor oversight under Regulation 17 (good governance) and unsafe medicines practice. Treat staffing as part of governance, not a stand-alone HR task. If CQC has already raised staffing, see how to write an improvement plan.
