Just to shine a little more light on the subject in the UK, if your EVSE is accessible to the public then you are subject to the provisions of The Alternative Fuels Infrastructure Regulations 2017 - specifically if
(2) A recharging or refuelling point is accessible to the public if it is—
(a)intended for use by members of the general public (including those situated in public car parks, whether or not those car parks are available only to consumers of specific goods or services); and
(b)not intended for—
(i)exclusive use in respect of a vehicle produced by a specific manufacturer;
(ii)use by persons engaged in specific occupations;
(iii)use by persons whilst at their place of employment (including visitors); or
(iv)exclusive use by occupiers of, or visitors to, residential premises.
Recharging points: intelligent metering and ad-hoc access
5.—(1) After 17th November 2017, an infrastructure operator must ensure that all recharging points for which that operator is responsible incorporate intelligent metering systems which comply with the requirements specified in paragraph 5 of the Schedule.
(2) An infrastructure operator must provide to any person ad-hoc access to—
(a)all recharging points deployed after 17th November 2017; and
(b)all recharging points deployed on or before 17th November 2017, no later than 18th November 2018.
(3) In this regulation—
“ad-hoc access” means the ability for any person to recharge an electric vehicle without entering into a pre-existing contract with an electricity supplier to, or infrastructure operator of, that recharging point.
There’s even more fun on the way with the later Automated and Electric Vehicles Act
