How to Change Utilities After Moving In as a Renter in Wales

Moving In & Out Procedures Wales 4 min read · published March 09, 2026 Flag of Wales

When moving into a new rented property in Wales, changing the utilities—such as gas, electricity, and water—can seem overwhelming. It’s crucial to ensure your name is on the correct accounts, bills are accurate, and your legal rights as a renter are protected. This guide covers the essential steps and official processes, using the latest tenancy legislation for Wales.

Getting Started: Understanding Your Utility Responsibilities

As a renter in Wales, whose name should be on the utility bills typically depends on your tenancy agreement. If you have an assured shorthold tenancy or occupation contract, you’re usually responsible for most utilities unless otherwise stated in your agreement.

  • Check your written contract for details about utility responsibilities
  • The most common arrangement in Wales is for renters to set up and pay their own utility accounts

Before moving in, always take meter readings and photograph them for your own records. This protects you from being billed for previous tenants’ usage.

Key Steps to Change Utilities After Moving In

1. Take Meter Readings Promptly

  • On your move-in day, record readings for gas, electricity, and, if available, water meters
  • Keep a digital/photo record as proof
  • Share these with both your landlord/agent and your new utility provider

2. Contact Utility Providers

  • Find out which companies currently supply your property—ask your landlord or letting agent if unsure
  • Contact each company to set up an account in your name, giving them your move-in date and initial meter readings
  • For water, your supplier in Wales is likely Dŵr Cymru Welsh Water

You are free to switch energy suppliers in most cases, but check your agreement for any restrictions.

3. Notify Your Local Authority for Council Tax

Register for council tax promptly to avoid penalties. Keep a copy of your confirmation or reference number and note any deadlines shown by your local council.

4. Understand Your Rights and Duties

Under the Renting Homes (Wales) Act 2016, landlords must ensure the property meets the "fitness for human habitation" requirements, including safe supply of gas, electricity, and water.1 You have a right to a safe home and fair access to utility services.

Nuance: even if the landlord is responsible for some utilities, you still have a right to a safe and reliable supply. If you notice safety concerns, request copies of safety checks and flag issues with your landlord and the supplier as soon as possible.

Official Forms Renters May Need

  • Rent Smart Wales "Contact Us" Form — If your landlord or agent fails to supply required information on utilities, use the Rent Smart Wales contact form to request support or to make a complaint.
    • Example: If your landlord refuses to share supplier details within a reasonable timeframe, submit your details and concern using this form.
  • Utility Supplier "Change of Tenancy" Form — Each supplier (e.g., gas or electricity company) will have their own online or downloadable "change of tenancy" form found on their website. This is used to formally transfer the account from the previous occupant to yourself. Visit your supplier’s official website for access.

In the rare case your dispute leads to a legal process, the Residential Property Tribunal for Wales handles such tenancy-related issues.2

Example: after submitting Rent Smart Wales or a supplier's change-of-tenancy form, keep a dated copy and track responses to avoid missing deadlines.
If you're unsure about any part of the process or feel pressured to pay for a previous tenant’s debt, always seek advice from your local Citizens Advice or contact Rent Smart Wales.

What to Do If There Are Problems

If your landlord does not provide information about current utilities, or if you discover unpaid bills left by a previous tenant, you are not normally responsible for the previous resident’s debts. Inform the utility supplier and provide proof of your tenancy start date (a copy of your tenancy agreement may be needed).

  • Contact the supplier with your details and move-in date
  • Send them your meter readings and tenancy agreement as proof
  • If you face continued demands for old debts or threats of disconnection, contact Citizens Advice Cymru
