Use this glossary as a starting point when reading studio guidance, council conditions or equipment manuals. A term can have a specific meaning in a particular council's rules or a manufacturer's instructions, so check the original source for decisions about your own studio.

Licensing and premises

Byelaw

A local rule made by a council under a legal power. Tattooing requirements and application processes can vary by council; read the conditions published by the council where you plan to work.

Premises registration or approval

The council process that applies to the place where tattooing is carried out. In England, both the practitioner and premises are generally registered with the council; Greater London has a different special-treatments route. In Wales, premises or vehicles need an approval certificate under the special-procedures scheme. Confirm the route with the council where you plan to work.

Practitioner registration

The local registration or licence process that applies to the person carrying out tattooing. In England, GOV.UK directs applicants to their local council. The legal route differs across the UK.

Special procedures

A term used in Wales for regulated activities that include tattooing. Wales has its own licensing scheme; do not assume that an England-focused council form applies.

Skin piercing

A broad licensing category used in official guidance that can include activities such as tattooing and certain forms of body piercing. Check the exact activities covered by your council's scheme.

Hygiene and waste

Clinical waste

A category of waste requiring a controlled disposal route because it can pose an infection or other health risk. HSE SR12 says blood-contaminated swabs and gloves should be treated as clinical waste. Ask your waste provider to confirm the classification and collection route for each waste stream; not all studio waste belongs in the same container.

Cross-contamination

The transfer of contamination from one person, surface, item or area to another. Infection-prevention guidance describes controls for reducing this risk; this short definition is not training.

Decontamination

The process used to make equipment or an area safe for its intended next use. The correct process depends on the item, its instructions and the applicable infection-control guidance.

HSE SR12

The Health and Safety Executive's guidance sheet for tattooing and micropigmentation. Its stated scope is good control practice for chemical substances hazardous to health, such as solvents and biocidal products. It also includes related precautions; use it alongside relevant infection-prevention guidance and council requirements.

Infection prevention and control (IPC)

Measures intended to prevent or reduce the spread of infection. UKHSA publishes tattooing and body-piercing guidance for England; follow the relevant national guidance and your council's conditions.

Sharps

Items capable of cutting or puncturing skin, such as tattoo needles. Plan a suitable container and collection route for used sharps in line with council, health and safety, and waste-provider requirements.

Single-use item

An item intended by its maker to be used once and then discarded. Follow its labelling and instructions; do not treat cleaning as permission to reuse an item marked single-use.

Equipment and workspace

Cartridge needle

A needle assembly supplied in a cartridge format for compatible tattoo machines. Check the machine maker's compatibility instructions and the cartridge's own packaging.

Coil machine

A tattoo machine that uses electromagnetic coils to move its armature and needle assembly. Setup and adjustment depend on the particular machine and the maker's instructions.

Footswitch

A foot-operated control used with some wired machine and power-supply setups. Confirm connector type and compatibility before purchase.

Grip

The part of a tattoo machine assembly held by the artist, or a compatible grip-and-tube component in some setups. Dimensions and connections vary between systems.

Power supply

The unit that provides and controls electrical power for a compatible tattoo machine. Verify output, connectors and operating instructions against the exact machine model.

Rotary machine

A machine that uses a motor and mechanism to move the needle assembly. “Rotary” describes a broad machine type; it does not by itself establish compatibility or performance.

Stroke length

The length of the machine's needle-driving movement, as specified by the maker. It is a separate specification from needle depth: Cheyenne's HAWK Pen manual lists both. Check the manufacturer's definition and available settings for the exact model.

Tattoo bed

A piece of client furniture designed to support a person during a procedure. Check adjustment range, stability, cleanable surfaces and room access against the studio's needs and applicable requirements.

Wireless battery

A battery unit attached to, or designed for, a compatible machine to provide power without a separate wired supply during use. Check the maker's compatibility and charging instructions.
