I have been asked to reply.
Local authorities in England have powers to regulate businesses providing tattooing under the Local Government (Miscellaneous Provisions) Act 1982. The 1982 Act enables local authorities to require the registration of tattooing practitioners and premises and to introduce local byelaws about the hygiene of the practitioner, premises and equipment used.
Local tattooing byelaws are confirmed by the Secretary of State. However, information about those councils in England which have had local tattooing byelaws confirmed could be obtained only at disproportionate cost, as it would involve identifying, obtaining and examining departmental records dating back to 1982.
Local authorities in London generally use powers in private legislation to regulate tattooing businesses—the Greater London Council (General Powers) Act 1981 or the London Local Authorities Act 1991. Therefore, the Department does not hold the information requested relating to London local authorities.
Information relating to Scotland, Wales and Northern Ireland may be requested from the relevant administrations.
