£400 energy rebate for 4 studio units when tenants are on the edge?

How do my tenants get the £400 energy rebate when they pay their gas bills as part of their rent? I have a house in 4 studio units, the water and gas are included in the rent payment while electricity is paid for with a £1 coin meter in each unit which I collect and pay to the utility company.

I have approached my supplier to have token meters fitted so each tenant can have their own bill but they have declined saying they are not carrying out this work at the present time (Bulb Energy).

All 4 tenants are vulnerable on full LHA and other benefits. As such they cannot pay any more towards costs and I cannot afford to continue to cover the rocketing energy bills they are running up.

I am guessing I could get one payment of £400 as the person named utility bill but I require £1600 to cover all 4 tenants.

This would then be paid to Bulb via me if not directly by whoever is paying the £400…

If they don’t pay then I have no option but to raise their rent which they cannot pay and then to end their tenancies and re-let to those who can afford the bills.

I have known these guys for years and consider them friends, this is a complete nightmare not just financially but on a personal/human level as well.
