Looks like an insulted version of a Bemco unit. Just out of curiosity, how close are bare live parts to the holes? IIRC the requirement is IP4X or IPXXD - the latter is somewhat more lax - as long as a 100mm long 1mm dia wire can't touch live parts, it could well comply technically.

The terminals i could see were a fair way down.  Do these sort of things generally have fuses in ? or do i have a load of unfused meter tails

Unless there is an obvious service head somewhere else - cant see on this one,

There will be a row of 100A fuses that belong to the DNO in the white box, probably a few per phase. Does it have anti tamper seals and how is your attitude for risk....

I may be tempted to go a little  wild with a mastic gun and split some universal grommets, assuming the holes are a standard size and 32mm.

and then get out and not ask too many questions.

Cheers Mike.   I can't get access again now without going through the estate agent. I'll just put it in the report and leave it to them to sort out if it needs it.  Thank you all for your help.

100 ± 0.2 mm long, 1 + 0.05 - 0.00 mm diameter  probe (specifically, Test Probe D in BS EN 60132), with a spherical limiter dimensioned according to the standard.

When fully inserted with a force of 1.0 ± 0.1 N, the the probe should not be within the relevant clearance distance of live parts (clearance distance varies with the product standard).

Some products standards vary the probe "delimeter" dimensions, tolerances and force applied (for very good reasons relevant to the product in question). Some product standards specify an insulation test or withstand test voltage to be applied for some of the access probe tests.

As long as that's done in a way that can cope with the force of 1 N (or higher force if required by the product standard) on the 1 mm steel wire probe.

I won't be touching it. It can be somebody elses problem.
