Two weeks before you move
Notify your current supplier of the move-out date in writing and request a final bill. At the new premises, identify the existing supplier and set up a change-of-tenancy account before you take occupation — this is what stops you defaulting to expensive deemed rates.
On the day
Photograph every meter at both properties with a timestamp. That single photo resolves the overwhelming majority of final-bill disputes.
- Record electricity, gas and water reads at the outgoing site
- Record the same at the incoming site
- Note MPAN, MPRN and serial numbers
- Keep the lease start date to hand as evidence of liability
Within 30 days
Once the change of tenancy is registered you are free to switch away from the deemed rate immediately. Do it early — deemed tariffs are usually the most expensive energy the site will ever buy.
