I have commented in the past, on various threads, that this EICR introduction is a time that Electricians will look back on as the "great feeding frenzy"... my view is backed-up here. I have already heard of many people being foxed into the purchase of new consumer units to meet current regulations... when an EICR is not retrospective in nature. Should you ideally have a metal-clad consumer unit? Sure. If you have a plastic one from 1990 does it mean the property has
suddenly become an immediate risk that needs remediation? No.
It's like Grenfell and cladding.
The ability for an Electrician to class the outcome as unsatisfactory does two things... it means you have a Sword of Damocles hanging over your head regarding more-or-less immediate action... and, by virtue of that, it effectively ties you into the same Electrician... not absolutely (you could throw money down the drain elsewhere of course)... but in practice (a Landlord probably wouldn't re-start the exercise). I bet Screwfix has had a massive rush on metal-clad consumer boards this year.

All those Landlords out there who have been frightened into taking remedial action that was not
necessary (although possibly advisable).
That said, there's a comment here about not having to do anything for the next 5 years unless the Tenants move out... please clarify what you mean by this? The EICR has a lifetime... Tenant movements should not affect this, right? I don't get a new GSC if a Tenant move out when it's in the middle of its lifespan. We (Landlords) should all be careful on this.
