Smart Meters that can be installed at the Consumer Unit

[Ray Pooley]

The landlord has absolutely no authority to prevent a smart meter from being installed

Like I said. It depends on what is deemed "unreasonable" and who deems it so.

I can't envisage the government breaking into a private property to force a smart meter on the owner on behalf of the electricity companies. Not yet at least.

Besides, it's never a good idea to pick a fight with the person who controls your rent payment or your tenancy. Not if you're happy where you are. About anything really and least of all a smart meter.
