The regulation of the small public service vehicle (SPSV) industry, including the making of licensing regulations for SPSVs, is a matter for the National Transport Authority (NTA) under the provisions of the Taxi Regulation Act 2013.
Under current legislation, there are three categories of SPSV licence available to those applying for a first-time licence, namely wheelchair accessible taxi, wheelchair accessible hackney, and limousine. I have no plans at present to change policy relating to categories of licence for SPSVs.
However, in order to be of assistance, I have referred your question to the NTA for their consideration and direct reply to you. Please advise my private office if you do not receive a response within 10 working days.
