Bloodborne viruses and hepatitis B vaccination

The three pathogens that drive tattoo bloodborne-virus (BBV) policy in the UK are hepatitis B (HBV), hepatitis C (HCV), and HIV. All three transmit blood-to-blood through needles, sharps, or contaminated equipment. Of the three, hepatitis B is by far the most easily transmitted by a sharps injury, which is why the vaccination is targeted at tattoo artists specifically. This guide describes the legal framework, vaccination, post-exposure protocol, and the Equality Act issue that catches studios out.

What the law expects

Three statutory levers apply:

The Health and Safety at Work etc. Act 1974, general duty to control bloodborne-virus risk to staff, clients, and others affected by your work.
The Control of Substances Hazardous to Health Regulations 2002 (COSHH), biological agents (HBV, HCV, HIV) are hazardous substances. Risk assessment, control measures, training, and post-exposure protocol are all COSHH duties.
The Management of Health and Safety at Work Regulations 1999, suitable and sufficient risk assessment, including BBV hazards and needlestick procedure.

The working national guidance is the HSE BBV risk assessment page (2026 update) and the UKHSA Green Book Chapter 18 on hepatitis B which explicitly identifies tattoo artists as an occupational risk group.

The three viruses, relative risk

Per HSE and Green Book guidance, the approximate risk per needlestick from a known-positive source:

Hepatitis B, up to ~30% transmission risk from an HBeAg-positive source if the worker is unvaccinated. This is why vaccination is targeted at tattooists.
Hepatitis C, approximately 3% transmission risk.
HIV, approximately 0.3% transmission risk; lower again if the source is on suppressive antiretroviral therapy with an undetectable viral load.

HBV is therefore the dominant occupational risk, by an order of magnitude. The vaccination is preventable; HCV and HIV are not vaccine-preventable and depend on standard precautions, sharps safety, and post-exposure prophylaxis.

Hepatitis B vaccination

Per UKHSA Green Book Chapter 18, tattoo artists are in an occupational risk group for HBV and should be offered immunisation. The course is three doses over six months in the standard schedule (0, 1, 6 months) or four doses on an accelerated schedule (0, 7, 21 days, 12 months) if rapid protection is needed.

Access and cost in 2025-26:

GP, many GP practices will not vaccinate occupational risk groups on the NHS unless you are employed and your employer pays. Self-employed tattoo artists often find their GP declines, refers to occupational health, or charges privately.
Private occupational health clinics, typical cost £150-£250 for the three-dose course, sometimes with antibody titre testing afterward.
Travel health clinics, same product, sometimes lower cost; check the certificate documents it as a course not a single dose.
Some councils subsidise BBV vaccination as part of licensing. Check yours.

After the course, an anti-HBs antibody titre test confirms response. The protective level is ≥10 mIU/mL. Non-responders (~5-10%) need a booster course. Document the test result in your training/medical records. EHOs and insurers may ask.

Post-exposure protocol, what to do after a sharps injury

If you sustain a needlestick injury, splash to broken skin, or splash to eye/mouth:

Immediate first aid. Encourage bleeding from the wound (do not suck), wash with soap and copious water for several minutes. For eye splashes, irrigate with saline or running water for 10-15 minutes.
Stop the procedure, do not return to the client until first aid is complete.
Document the incident, date, time, mechanism, source client details, your vaccination status, first aid given.
Seek urgent occupational health or A&E advice within hours, not days. HIV post-exposure prophylaxis (PEP), if indicated, is most effective within 1 hour and ineffective beyond 72 hours. HBV post-exposure may require a booster vaccination or HBIG (immunoglobulin) depending on your vaccination history and the source status.
HCV, no post-exposure vaccine or prophylaxis. Baseline + 6-month + 12-month antibody testing.
Follow-up, repeat antibody testing per the occupational health protocol.

Every studio needs a written post-exposure protocol in its health and safety file. The EHO will check this. See the first aid in the studio guide for related procedure.

The Equality Act trap, refusing tattoo service

This is the issue that catches studios out.

Per Equality Act 2010, HIV is a protected disability from the point of diagnosis, and chronic hepatitis can be a protected disability depending on its long-term effects on the person. Refusing service to a client on the basis of disclosed HIV or hepatitis status is unlawful discrimination in the provision of services under Part 3 of the Act.

The National AIDS Trust and BHIVA are explicit on this, the correct safeguard is universal precautions, not screening clients. You should not ask clients about HIV or hepatitis status on your consent form. If a client volunteers their status, you must not treat them differently from any other client.

The legal and clinical reasoning is the same: every client is treated as if they could be infectious (standard precautions). Asking about BBV status:

Has no clinical justification, your precautions are universal regardless of the answer.
Risks unlawful discrimination if it leads you to refuse service.
Creates a UK GDPR / Data Protection Act 2018 issue, health status is special-category data, and asking for it without lawful basis is a data protection breach. See client records and UK GDPR.

What you can ask about on the consent form:

Medications affecting bleeding or healing (warfarin, DOACs, immunosuppressants).
Conditions that affect skin healing (severe diabetes, autoimmune skin conditions).
Pregnancy (relevant for some placements and aftercare).
Recent surgery or major illness affecting fitness for the procedure.
Allergies relevant to the procedure.

None of these require BBV status disclosure.

Standard precautions, the actual prevention

The combination that prevents BBV transmission in practice:

Hepatitis B vaccination for every artist before they tattoo independently.
Universal standard precautions treating every client as potentially infectious, see infection control basics.
Single-use sterile cartridges and disposables, no reprocessing of items in contact with blood.
Sharps protocol, never recap, dispose immediately, BS 7320 containers. See clinical waste and sharps.
PPE discipline, gloves change between clients and during procedures if compromised, aprons, eye protection where splash risk exists.
Post-exposure protocol documented and rehearsed.
Training records, bloodborne pathogens course completed and refreshed at intervals.

What this guide cannot do

This is a framework summary. The clinical detail on PEP timing, HBV vaccine response, and occupational health protocol is medical territory, get it from your GP, an NHS occupational health service, or BHIVA guidance.

Information, not advice. For your situation, verify with your GP or occupational health provider, and consult the HSE BBV guidance and the UKHSA Green Book linked above.
