Water bills: Plan 'extra regulation' says landlords chief
Water customers are paying £20 extra on annual bills to cover the cost of those who do not pay up and the figure could rise, it is claimed.
Bad debt written off by water companies and passed on to customers has increased by 430% over three years.
The Welsh government estimates the majority of debtors live in rented accommodation.
It is consulting on new regulations to force landlords to pass on tenants' details to water companies.
Lee Cecil, head of the National Landlords Association in Wales, spoke to BBC Wales political reporter James Williams.
