It’s usually simple to figure out who your gas or electricity supplier is if you’ve recently moved into a new home. Asking the estate agency, landlord, or former owner of your property who supplies your energy is the easiest way to find out.
At the time of leaving the premises, some tenants contact the gas and electricity supplier to inform them that they are moving. If the former occupant of your home has already done this, the energy provider will most likely send you a letter addressed to ‘The Occupier’ in the near future. This letter should contain all of the information you require regarding your gas and electricity (or dual fuel) provider.
If you have been at your new home for a while and the previous tenant hasn’t informed the gas or electricity supplier that they were moving out, you’ll have to call your local electricity distribution company and the Meter Number Helpline at the numbers listed above to determine your supplier in these cases.
