But do they all carry ladders? ;)
I suspect that with health and safety madness, most of them would not be allowed to climb up a ladder to go and read a meter.
Having electricity meters in a cupboard that requires a ladder to access is almost certainly in breach of some regulations though.
Probably disability regs if nothing else.
As such, I’d just recommend that you request that your landlord either provides you with meter readings monthly, or that they move the meter into an accessible position.
If it’s your own property, perhaps get the meter moved?
Bulb do state they require safe access (which acess via a ladder is probably not considered to be):
6.1. In order to provide you with energy, from time to time we require access to your meter. You agree to provide us, or any person we have authorised acting on our behalf to safe, unrestricted access to your energy metering and associated equipment. If your metering equipment is obstructed, it is your responsibility to remove it or the obstruction and pay any associated costs.
The terms from Bulb also advise:
3.15. So we can bill you as accurately as possible, you must give us an up-to-date meter reading for your energy at least every 90 days and when requested by Bulb if there is a reason to need more up to date meter readings.
