Sterile services technician

Sterile services technicians make surgical instruments safe to use again. They receive used trays from theatres and clinics, clean and disinfect them, inspect and reassemble each set, then sterilise and track them back out. Most NHS posts are band 2 (£25,272 in England from 1 April 2026), with senior technician and supervisor roles at band 3 and above. You do not need a degree or previous healthcare experience.

Inside a sterile services department

The department goes by several names: sterile services department (SSD), hospital sterilisation and decontamination unit (HSDU) or decontamination unit. Some sit inside a hospital, and others are large central units serving several hospitals. The work runs as a cycle, and you usually rotate between its stages:

1. Used instruments arrive in sealed containers. You sort them, carry out any manual pre-cleaning, and load them into washer-disinfectors.
2. In a clean area, you check each instrument under magnification for damage or remaining dirt, test that it works, and rebuild the set against a checklist. Sets can contain dozens of instruments, and every one must be there.
3. Sets are wrapped or put into containers, labelled and sterilised, usually in steam autoclaves.
4. Each tray is scanned on dispatch so it can be traced to the patient it was used on, which is how a hospital follows up any contamination concern.

Endoscope decontamination is a separate specialism with its own equipment and training, and some hospitals run it in the endoscopy unit rather than the main SSD.

Training and what employers ask for

Most technicians are trained on the job. Employers look for:

• the ability to follow detailed written procedures exactly
• attention to detail and good eyesight (correction is fine)
• basic literacy and numeracy for checklists and tracking systems
• willingness to work shifts and stand for most of the day

You will be signed off on each stage of the process before working on it alone. Some trusts offer level 2 or level 3 qualifications in decontamination, sometimes through an apprenticeship. The Institute of Decontamination Sciences (IDSc) is the professional body for staff who want to develop further. NHS jobs you can get without a degree lists similar entry-level routes.

As in other NHS roles, you will need references and occupational health clearance, including vaccinations such as hepatitis B, because of the risk of sharps injuries.

Pay

Role	Usual band	England, from 1 April 2026	Scotland, 2026/27
Technician	2	£25,272	£26,658 to £28,947
Senior technician or team leader	3	£25,760 to £27,476	£29,061 to £31,364
Supervisor	4	£28,392 to £31,157	£31,492 to £34,254

Managers of large units are graded higher. Many departments run long hours or around the clock to keep theatres supplied, so evening, night and weekend shifts are common and paid with unsocial hours enhancements. Band 2 has only one pay point, so shift payments and overtime are often what lift earnings above the base salary. The take-home pay calculator shows what you would keep.

Some trusts have moved sterile services into wholly owned subsidiary companies or private contracts. If that happens to your department, TUPE may protect your terms, but new starters can be on different terms. Check who the employer is on the advert.

Why the rules are strict

Instruments that are not properly cleaned can carry infection from one patient to the next, so detailed national guidance governs decontamination and departments are audited regularly. Many units hold certification against quality standards, and every load through a washer or steriliser is logged with its test results. If a cycle fails, the load is held and reprocessed. Some infectious agents, such as prions, are not reliably removed by normal processes, and there are special procedures for instruments used on patients at risk. You learn these rules in training, and you are expected to stop and report a concern even when theatres are waiting. The job suits people who take satisfaction in getting routine work exactly right.

Conditions

The work is physical: standing for long periods, lifting heavy trays and containers, and working in warm areas near the washers and sterilisers. In the clean room you wear protective clothing and hair covering. Shift patterns depend on the theatre schedule, and the department can be under pressure when theatre lists change at short notice.

Working time rules apply as anywhere else: an average of no more than 48 hours a week over 17 weeks unless you opt out in writing, and a 20-minute break when you work more than six hours.

Full-time Agenda for Change staff get 27 days of annual leave plus eight public holidays to start, and NHS Pension Scheme membership, with a contribution rate of 6.5% at band 2 and band 3 pay.

Progression

Technicians can move into senior technician, supervisor and quality roles within decontamination, and in larger units into training or management posts. The work also gives a good grounding for theatre support worker posts and other hospital roles. Search NHS Jobs for “sterile services” and “decontamination”, or browse NHS facilities jobs.
