Fitting a smart meter

I understand smart meters have to be fitted to all UK households by a certain time. I switched to Bulb just recently and asked when they were rolling out a smart meter programme. I cannot remember the answer. Could you update the situation

It is a misconception at present you don’t have to have a smart meter although energy suppliers must offer them by 2020. Details of the roll-out can be found on Bulb’s page at: https://help.bulb.co.uk/hc/en-us/articles/115001232872-When-will-Bulb-roll-out-smart-meters-

Thanks @Allanr, all the details are there @hawkeye if you have any further questions please do let us know
