Smart meters - Avoid?

[Dr Murdoch]

It appears I signed up to a British Gas tariff that requires the installation of a smart meter. I can switch to a more expensive tariff (mid-term) or have the smart meter installed.

Ae there any drawbacks to having the smart meter, or is it ok to crack on and have it installed?

They're incentivising you to have one. Now why would that be - because you benefit, or them?

Which is/was my concern, hence the question. I'm sure they benefit, but at my expense? If so, can this be quantified?
