I too am in the gas only club. I had my smart meters fitted 17May. I have emailed bulb to get myself on the waiting list for it to be fixed as it’s done in order of when the requests are received. Going by what’s been said on here, it could be weeks or even months. I’m going to try what’s been said on here by turning my ihd off at night and turning it back on in the morning and see what happens.
