Landlord services
The Welsh Government have introduced regulations that impact on any landlord whose property receives water or sewerage services from Welsh Water.
The regulations require landlords to ensure Welsh Water are informed of any change of tenants in their properties within 21 days. If this isn’t done, the landlord can become jointly and severally liable for the water and sewerage charges.
We need to know:
- The property address
- The title, full name and date of birth of all adult residents
- The tenancy start date
Our preference is that the information is provided through landlord tap. Anybody can register to provide information and use this website. It’s easy to use and a permanent record is kept of updates which offers the landlord confidence that the information has been passed to us, as the evidence is there to see.
Alternatively you can get in touch with us and provide the information to us directly.
You can also get a copy of the Welsh Government’s guidance.
Is your property currently empty?
If a property that you own is empty, you are responsible for the payment of water and sewerage charges
This is because most properties, even when they are empty between tenancies, need access to water for things like gardening, cleaning, flushing toilets and maintaining the heating system. Therefore, charges are payable by the occupier or owner of all properties to which water and / or sewerage services are available. These charges cover maintaining a water supply to the property, taking away surface water and, where there is a water meter, taking readings and maintaining the meter.
Since October 2024, Landlords are responsible for payment of these charges at the property until it becomes occupied or is sold. If the property doesn’t have a water meter you may want to get a meter fitted so that you are billed for the water that you use.
If you do not want to pay any charges, you can choose to have the property’s water services permanently disconnected. This would mean that, when the property becomes occupied in the future or when it is sold, a new connection would be required, and this would be at a cost to you.
