Your problem is that the DNO and the gas supplier can remove their service for safety reasons and make safe any existing equipment (or its remnants). That would be agreed in the very first contract for the installation of service. They cannot charge the HA for that activity.
That has unfortunately come to pass.
(The DNO and elec supplier could charge the person causing damage for the costs, but probably have concluded that such action would be impractical and not cost effective. You have no rights to control their decision)
The HA (or original builder) asked for supply equipment to be connected and that was done. They have not paid for anything else. However, the HA as the property owner still wants a supply system and so will need to agree the terms and the costs of re-providing it.
I doubt that the original contract made with the DNO, to install a supply system, undertook to provide ongoing and unending maintenance of that equipment. (Probably the maintenance of the supply lines is in an agreement between the elec service supplier and the DNO.
The supplier and the DNO are in the driving seat, as they have no obligation to the HA nor the tenants to cooperate.
Surely a HA is aware of the risks they face as landlords?
The van analogy is flawed; you (to make your house more attractive for rent) paid a van owner (DNO) to place a van in your garage. Later, the van owner agreed to let somebody (BG) hire it and then sub-hire it to your tenant. The van got damaged. Why should its owner place another one on your property and possibly repeat the experience?
