A Change of Tenancy (CoT) transfers responsibility for a site's electricity/gas supply when a business moves in or out. If you don't inform the supplier, they'll put you on "deemed" rates that can be double the normal tariff.
1. Prepare Key Documents
- Letter of Authority (LOA): If using a broker, sign an LOA permitting them to act on your behalf
- Tenancy or Lease Agreement: Proof of the change in occupancy
- Meter Details and Readings: Serial numbers and photos of readings on moving day
- Forwarding Details: Contact info for the outgoing/incoming tenant
- Site Info: Property address and MPAN (electricity) or MPRN (gas) from a previous bill
2. Notify the Supplier
Most suppliers require CoT notification within ~28 days of the move. Contact them as soon as your moving date is set.
Include:
- Date of tenancy change
- Your business details
- Proof of occupancy and meter readings
- Previous occupant's name and forwarding address
Early notification is critical. Deemed rates are typically 40-60% above normal contract rates.
3. Confirm the Transfer
The supplier should confirm (usually within 5-30 days) that the account is in your name. Verify:
- Final bill for previous tenant: Ensure the old account is closed so you aren't billed for energy before your start date
- Opening meter read accepted: Prevents overlap charges
- Contract status: You'll likely be on a rolling arrangement and free to switch suppliers
4. Verify Meter Details
Check your first bill:
- MPAN/MPRN and meter serial match your actual meter
- Profile class is correct for your business type
- Tariff: Plan to arrange a proper contract rate quickly
5. Shop for a Better Deal
With the CoT completed, compare quotes from other suppliers or negotiate with the current one. No penalty for switching when you've just taken over.
