Apologies if this is the wrong forum! I live in a flat above a retail unit, which is rented from the owner of that unit. My gas supply doesn't come directly from a gas company, but rather the unit below. There is a submeter installed, when I moved in my landlord told me to text them a regular meter reading, and they would calculate how much gas we had used and then let me how much I owed them. All "bills" were sent over text, and payment was requested in cash (I asked to do a bank transfer as it was easier for me, but the landlord insisted on cash payment), and no receipts were given. I started off providing regular meter readings, but the bills grew further and further apart. I haven't had one in about 3 years now, and they have never come to read the meter themselves. They haven't responded to attempts to contact them for close to a year now, and I'm now looking at moving out because the flat is becoming uninhabitable/dangerous due to a lack of repairs. I've looked at the tenancy agreement (which has now rolled over from an assured shorthold tenancy and become a statutory periodic tenancy), and it says nothing specifically about paying the landlord for our gas, just that "the tenant shall pay all charges for gas and electric current supplied to the premises". There's no mention of costing, when, how or to whom it should be paid, etc. I'm just wondering where I stand here? If they were an energy company, I don't think they'd be able to backbill me for the whole period as they've never read the meter at all, or provided me with a bill for three years now. With no receipts and cash payments, there's no evidence of what has or has not been paid, either. I'm just worried that they're going to try and hit me up for 3 years (or more) of gas bills when I give them notice.
