Change of Tenancy (CoT)

Moving business premises

If your business is on the move, you’ll need to know about our 3-step change of tenancy (CoT) process. Following it will help ensure that you only pay for the period you’re responsible for, while also protecting your business.

As an additional safeguard, we may phone your business – and/or the landlord of the premises – to verify the information you’ve provided. In all cases, by getting and checking the right details, we can make sure that the CoT process goes as smoothly and efficiently as possible.

Step 1: Fill the form

Select the right form from the three options below. Each one asks for a meter reading (here’s our guide on reading your meter) – or you can simply send us a photo of the reading.

Please note that if your premises has a Half Hourly meter, we’ll receive readings automatically and may not use your manual read to produce your invoice.

Send your completed form, with the date of the reading/photo, to

To allow us to verify your information and protect your business, please email with one or more of the following:

-Lease agreement
-Deed of surrender
-Freehold, Leasehold or Transfer of Title (TR1) documents from the Land Registry
-A letter from your solicitor

Step 3: Sit back and relax

We’ll check your form, make sure we have everything we need to complete your CoT, then get back in touch.

Broker or consultant?

If you’re a broker or consultant and your client has moved into premises on supply with Haven Power, we’ll need a signed Letter of Authority form.

This will allow us to liaise with you about the client’s account, although there may be times when we need to speak directly to your client.
