A large part of the compliance and the effort in  the technical file will not be under the HSE machinery at work  remit if it is intended for home use, but rather  falls under the rather quaint title of weights and measures, which is where the responsibility for enforcement of all the EMC and related legislation falls.

Between them, the HSE and the various trading standards folk for each local authority are the UK's main  market surveillance authorities (MSA) . HSE looks mostly at the workplace, and trading standards the rest.


As such local authority trading standards are the folk who can (but rarely do) demand  to see the maker's technical construction files  (TCF) or other proof of compliance in respect of those standards.

It is largely left to those placing equipment on the marked to decide which of the various standards apply to their product, and then to sign some statement to say that they believe they do. Personally I have very little to do with the HSE, but my experience of trading standards is that they are not really well enough staffed with the right sort of folk and equipment for the modern role - inspections of market stalls selling dodgy burgers well kitted out perhaps, but subtleties about conducted  emissions from doubtfully CE marked kit, which is what we have here, most are likely to be rather on shaky ground.

In many ways the regulatory regime is too fragmented and too complex to work as intended, so it is very 'wild west'.
