What a Change of Tenancy Means for Your Energy
When a business takes over the lease on a commercial unit, office or other premises, the energy supplier needs to know that responsibility for the electricity and/or gas meter has passed to a new occupier. This is usually referred to as a change of tenancy, or “COT”. Getting this registered promptly helps make sure your business is billed correctly from your actual move-in date, rather than being left tangled up in a previous occupier’s account.
It also gives you the opportunity to agree your own contract terms with a supplier of your choice, rather than simply inheriting whatever arrangement (or lack of one) the previous tenant had in place.
How the Change of Tenancy Process Works
Confirm your move-in date
Your lease start date or the date you take occupation is the key reference point for the whole process.
Take a meter reading
An opening reading, ideally with a photo, protects you if there is ever a dispute over usage before your tenancy.
Register the change and agree a contract
We help you notify the right supplier and put a contract in place under your business name.
What Information We Need
To give you the most useful review, it helps if you can provide:
- The premises address and your lease/move-in date
- A meter reading, and photo if possible
- MPAN (electricity) or MPRN (gas) reference, if known
- A contact name, phone number and business email
- Details of the previous occupier’s supplier, if known
Don't have everything to hand? That's fine - fill in what you can and a specialist can help with the rest.
