Credit scores are attached to individuals and not linked to an address.
I've had tenants who used my address (whilst between moves) for forwarding their utility bills. Should you receive chasing letters on your tenant's behalf, simply contact the utility provider and instruct them to remove your address details from their system - this is your right under GDPR. Do not give the utility provider your name - not your bill and therefore not relevant. It is up to the utility provider to track their customer at their current address.
These bills/debts are not yours and you cannot be pursued for them
