What NHS panels look for in domestic assistant and ward housekeeper interviews, 14 practice questions with tips, a worked STAR example, common mistakes and a one-week preparation plan.

Last updated 24 October 2026 · Created by a practising NHS doctor · Independent of the NHS

Quick answer

What questions are asked in an NHS domestic assistant interview?

Expect questions on why cleaning matters for patient safety, colour coding, COSHH and safe chemical use, dealing with spillages, cleaning infection rooms, working around patients with privacy and dignity, prioritising tasks and teamwork with ward staff. Answer with short STAR examples, explain that you follow procedures and escalate concerns, and link your answers to the NHS values.

Key takeaways

Link cleaning directly to patient safety.
Know colour coding, hand hygiene and COSHH basics.
Never suggest shortcuts with chemicals or procedures.
Show respect for privacy and dignity.
Prepare three or four short STAR examples.

NHS domestic assistant and ward housekeeper interviews usually test four things: your understanding of why cleaning matters for patient safety, basic infection prevention and control, safe use of cleaning chemicals under COSHH, and how you behave around patients, visitors and clinical staff. Expect a mix of values questions and scenario questions such as "what would you do if you found a spillage?", and answer them with short, practical examples. You do not need previous hospital experience for most posts, but you do need to show you are reliable, careful and kind.

This guide covers what the roles involve, what panels look for, 14 practice questions with tips, how to talk about cleaning standards, infection prevention and COSHH at the right level, a worked STAR answer, common mistakes and a short preparation plan. It is written for domestic assistants, ward housekeepers and similar hotel services roles. Portering is covered in a separate guide, and catering roles have their own guide too.

What does an NHS domestic assistant or ward housekeeper do?

A domestic assistant keeps wards, clinics and public areas clean to the standard the trust sets, while a ward housekeeper often has a wider role covering cleaning schedules, stock, linen, the ward environment and sometimes meal service. Job titles and duties vary between trusts, so read the job description closely.

Both roles are part of the clinical team in a practical sense. A clean, well-organised ward reduces the risk of infection, helps patients feel cared for and lets nurses spend more time on clinical work. Panels want to hear that you understand this link, not just that you can mop a floor.

Typical domestic duties: routine and deep cleaning of bays, side rooms, toilets, kitchens and offices, following a schedule and recording what you have done.
Typical housekeeper duties: checking cleaning standards, ordering and rotating stock, managing linen, reporting maintenance faults and supporting a welcoming ward environment.
Shared expectations: following infection prevention policy, using chemicals safely, respecting privacy and dignity, and communicating with the nurse in charge.

What do interview panels look for in a domestic assistant?

Panels look for someone dependable who follows procedures, takes pride in their work and treats patients with respect. They usually score answers against the person specification and the NHS values, so it helps to link your examples to both.

Reliability: turning up on time, finishing your schedule and telling your supervisor if you cannot.
Attention to detail: cleaning high-touch points such as handles, call bells and bed rails, not just what is visible.
Following procedures: colour coding, dilution instructions, signage and records, even when busy.
Infection prevention awareness: hand hygiene, protective equipment and knowing when to ask for advice.
Respect for patients: knocking, explaining what you are doing and protecting privacy and dignity.
Teamwork: fitting your work around clinical care and responding to requests from nurses.
Speaking up: reporting hazards, faults, spills and concerns about patients promptly.

What are common NHS domestic assistant interview questions?

Most questions are about safety, standards, patients and teamwork. These are typical practice themes to prepare for, not real questions from any interview.

Why do you want to work as a domestic assistant in the NHS? Link cleaning to patient safety and say what draws you to a hospital setting.
Why is cleaning so important in a hospital? Talk about reducing the spread of infection and creating a safe, dignified environment.
What is colour coding and why is it used? Explain that different colours of equipment are kept for different areas so germs are not carried between them.
What does COSHH mean to you? Show you understand safe storage, dilution, labelling, protective equipment and reading safety information.
What would you do if you found a spillage of blood or body fluid? Make the area safe, follow the trust spillage procedure and use the correct kit and protective equipment.
How would you clean a room where a patient has an infection? Follow signage and isolation instructions, use the right equipment and ask the nurse if unsure.
A patient asks you to come back later because they are resting. What do you do? Respect their wish where it is safe, adjust your schedule and let the nurse know.
How do you make sure you do not miss anything on your schedule? Mention checklists, a set routine and signing records accurately.
What would you do if you ran out of a cleaning product halfway through a shift? Report it, use only approved alternatives and never mix chemicals.
A nurse asks you to clean a bay urgently but you are in the middle of another task. How do you handle it? Prioritise by risk, communicate and tell your supervisor.
How would you respond to a visitor who complains the ward is dirty? Listen, apologise, act on what you can and escalate the rest.
What does privacy and dignity mean when you clean around patients? Knock, introduce yourself, explain and keep curtains and doors as the patient wishes.
Tell me about a time you took pride in doing a job well. Any setting works, as long as the detail is specific.
What would you do if you saw a patient who looked unwell or had fallen? Stay with them if safe, call for help immediately and do not try to lift them.

How do I talk about cleaning standards in an NHS interview?

Say that NHS cleaning follows set standards and schedules that decide how often each area is cleaned and how results are checked, and that you would follow your trust's version carefully. In England, trusts work to national standards of healthcare cleanliness, and the other UK nations have their own guidance, so describe them in general terms unless the advert names something specific.

You do not need to quote the documents. Panels want to hear that you understand the ideas behind them.

Risk-based frequency: high-risk areas such as critical care or isolation rooms are cleaned more often than offices.
High-touch surfaces: door handles, light switches, bed controls, call bells, taps and toilet flushes need regular attention.
Clean to dirty, high to low: a common principle so you do not spread dirt back onto cleaned areas.
Records and audits: cleaning is recorded and checked, so accurate sign-off matters.
Colour coding: many trusts use a national scheme, commonly red for toilets and washrooms, blue for general areas, green for kitchens and yellow for isolation, but always check your trust's chart.

What should I know about infection prevention and COSHH for a domestic role?

Know the principles: good hand hygiene, the right protective equipment, keeping equipment and areas separate, and handling chemicals safely. You will be trained in your trust's own policies, so the panel is checking your attitude and basic understanding rather than technical detail.

COSHH stands for Control of Substances Hazardous to Health, the regulations that cover safe use of hazardous substances at work. In an interview, keep it practical.

Hand hygiene: clean your hands before and after tasks, after removing gloves and between areas.
Protective equipment: wear what the task and signage require, and put it on and take it off in the right order.
Read before you use: check the label and safety information, and dilute exactly as instructed.
Never mix chemicals: some combinations can release harmful fumes.
Store and label safely: keep products locked away from patients, especially on wards with confused patients or children.
Report problems: skin reactions, damaged containers or unlabelled bottles should go to your supervisor.
Ask when unsure: the infection prevention team and nurse in charge are there to advise.

What is a good STAR answer for a domestic assistant interview?

A strong answer shows you following procedure, protecting a patient and communicating with the team. This example works for a question about safety, patients or teamwork, and you can use an example from retail, hospitality or care if you are new to hospitals.

Example answer: a spillage near a confused patient

Situation: I was cleaning a bay on a care of older people ward when I noticed a large spill of liquid by a bed, and the patient, who was often confused, was trying to get up to walk to the toilet.

Task: My priority was to stop anyone slipping, keep the patient safe and get the spill cleaned properly.

Action: I calmly asked the patient to wait a moment and pressed the call bell so a nurse could help him walk. I put out a wet floor sign straight away and stayed between him and the spill until the nurse arrived. I told her what I had seen in case it was a sign of a health problem. I then checked what the liquid was, used the correct spillage kit and protective equipment, cleaned the area following the ward procedure and disposed of the waste correctly. I made sure my trolley and chemicals were not left unattended near the patient.

Result: Nobody slipped, the patient got to the toilet safely with the nurse, and she thanked me for flagging it. I learned that my job is about safety as much as cleanliness, so I now scan each bay for hazards and confused patients before I start work.

What mistakes should I avoid in a domestic assistant interview?

The biggest mistake is treating the role as "just cleaning" and missing the link to patient safety. Other common mistakes are easy to fix with a little preparation.

Undervaluing the role: panels want to hear that you see cleaning as part of patient care.
Suggesting shortcuts: never say you would skip steps, guess dilutions or mix products to save time.
Ignoring the patient: remember privacy, dignity and asking permission before cleaning near someone.
Acting outside your role: do not say you would lift a fallen patient or give advice about their care.
Vague answers: "I am hard working" scores poorly without an example.
Forgetting to escalate: say who you would tell, such as your supervisor or the nurse in charge.
Poor punctuality on the day: arriving late undermines everything you say about reliability.

How should I prepare for an NHS domestic assistant interview?

Spend a few days learning the basics of the role, preparing three or four examples and practising aloud. A focused week is usually enough.

Step 1: Read the job description and person specification and note every skill they mention, such as reliability, teamwork or following procedures.
Step 2: Read about the NHS values and pick one or two you can link to cleaning, such as compassion and working together for patients.
Step 3: Learn the basics of colour coding, hand hygiene, protective equipment and COSHH in plain words.
Step 4: Prepare three or four examples from work, volunteering or home that show reliability, attention to detail, kindness and teamwork.
Step 5: Write each example as STAR bullet points and practise saying it aloud in about two minutes.
Step 6: Prepare two questions to ask, for example about training or the areas you would work in.
Step 7: Plan your journey, bring any documents the invite asks for and arrive early.

Frequently asked questions

Do I need experience to become an NHS domestic assistant?

Many domestic assistant posts do not ask for previous hospital experience, and full training is usually given on starting. Panels look for reliability, willingness to follow procedures and a caring attitude. Experience in cleaning, hotels, hospitality, retail or care can help, as can volunteering. Some adverts ask for basic literacy and numeracy so you can read labels and complete records, so check the person specification carefully before applying.

What is the difference between a domestic assistant and a ward housekeeper?

A domestic assistant mainly carries out cleaning to set schedules and standards. A ward housekeeper often has a broader role, which may include checking cleaning standards, managing stock and linen, reporting maintenance issues, supporting the ward environment and sometimes helping with patient meals. Housekeeper posts may be at a slightly higher band in some trusts, but duties and bands vary, so read each job description rather than assuming.

What does colour coding mean in NHS cleaning?

Colour coding means cloths, mops, buckets and other equipment are kept in different colours for different areas, so germs are not carried from one place to another. Many trusts follow a national scheme where red is commonly used for toilets and washrooms, blue for general areas, green for kitchens and yellow for isolation areas. Always follow the chart your own trust uses, as local practice can differ.

Is there a practical test in a domestic assistant interview?

Some trusts include a short practical task, a basic literacy or numeracy check, or a scenario discussion, while others use a straightforward interview. The invitation letter or email usually explains the format, and you can contact the recruitment team if it is unclear. If there is a practical element, take your time, follow any instructions given, ask questions if unsure and talk through what you are doing.

What questions should I ask at the end of a domestic assistant interview?

Ask about things that matter to doing the job well. Good options include what training and induction are provided, which wards or areas you would usually work in, how shifts and rotas are arranged, and what a typical day looks like. You could also ask how the domestic team works with ward staff. Avoid asking only about pay or breaks, although checking shift patterns is reasonable.
