- I can't access my meter?
If your meter is held in a meter box you can buy a meter key. These are readily available from any local DIY store or eBay, and will set you back a couple of quid.
If you live in a block of flats it might the case that your meter is locked away in a separate room or cupboard. If it's a rented property, it's the responsibility of your landlord to ensure you have access to obtain readings regularly, sometimes the key is kept by a caretaker or the property management company.
