I now have a smart meter, so no meter reader required, but until fitted we would see them on a regular basis, about once every 3 months. They would at first knock on the door, but they got to know where the meter was it was left open, so would just go down and read it.
We got a smart meter as they would not pay for export without one, but the advert says they mean more accurate bills, with less estimation, there is some, as idea is we over pay in summer so bills not so high in winter, and with no solar our bill was around £140 a month, but with an account balance of £535.50 we would not likely to have to pay anything for 5 months, so clearly it is not in practice giving us more accurate billing, it is way out. And only been with this supplier since May this year. The first 6 weeks, the bill was less than £5, I would expect if we did not charge battery with off-peak, December would cost around £83 as we use around 12 kWh per day, and December is the worst month for solar at around 95 kWh so at 30.17p/kWh that's around £83, but the battery will be charged at 8.5p/kWh and used until down to 10%, so more like £50 for December, plus standing charge that makes it £70 for December, so paying £77.80 a month is well over the top. So all the advert says seems to be wrong, so why is the ASA letting the government get away with it, it is so clear no one of her age will be gardening at night, what a daft thing to say.
As to riding a bike to make meter readings, in Ipswich may be, quite flat, but here in mid-wales, we do have a few hills, I can't get up many of them even with an e-bike, so not really an option. But notice the farmers who need to get in and out of their vehicles a lot, use quads, so meter reader on a quad? Nearly called it a quad bike, but can't be a bike with 4 wheels.
