“Ecotricity and Letters of Authority

In order to act on your behalf in securing your business a great energy deal Ecotricity require us to have a signed Letter of Authority from yourselves.

eSign – Fast, Convenient Online Approval

The fastest way to authorise us to work on your energy supply arrangements is to use our eSign service to agree our Evergreen Letter of Authority.We’ll take care of all correspondence, handle all the loose ends and enable you to focus on establishing your business in its new premise.And what’s more once your contract is in place we’ll manage your supplier relationship from beginning to end, all part of the Business Juice service.

Change of Tenancy and Ecotricity

Moving into a premise is known as a Change of Tenancy in the business energy market. It has also been termed a Change of Occupier or is known by its acronyms CoT and COO. However it is referred to, the opportunities it opens up are the same.This is great news for deal seekers. Whilst the existing supplier is obliged to continue to provide energy to the new occupier, the occupier is not obliged to take out an extended contract with that supplier.Indeed a Change of Tenancy customer has total freedom of movement and is free to accept a contract with a supplier of their choiceThere are however of course a number of rules and requirements.Firstly, as the new occupier, if you use energy you will need to pay for it, regardless of your contractual status.Secondly, you will need to identify as quickly as possible the identity of the existing supplierThirdly, you will need to field calls from sales organisations and the existing supplier themselves offering you contracts of varying lengths to continue or to begin to supply the premises.As a result as a new occupier you will need to agree a new contract either with the existing supplier or with a new supplier of your choice.Not only that but you will need to inform the existing supplier as quickly as possible that you are the new tenant to prevent you being held liable for charges incurred by the previous occupier should they not have ended their agreement satisfactory.It can prove a real headache knowing whom to trust – whether it’s the old tenant, the landlord the current supplier, the pushy salesman ringing, knocking and emailing, the prospective new suppliers.That’s where Business Juice comes in, by working on your behalf, identifying your existing supply arrangements, reporting your change of tenancy, ensuring you are not held liable for costs not incurred before your occupation and benchmarking contracts for your selection we can help you save time, money and a whole lot of stress.


If your prices change, Ecotricity will provide you with at least 28 days notice of the new rates, you will then be able to leave after providing 28 days notice that you don’t wish to continue on supply at the new rates.In all other circumstances you are required by Ecotricity to provide 28 days notice of your wish to end the agreement.

Rollover contracts and Ecotricity

Ecotricity uniquely operates a policy of 28-day rolling tariffs with no contract. As a result you do not have to terminate your existing contract by a specified date to avoid being automatically extended by 12 months, however your prices can change periodically if you stay on contract beyond the 28-day term.Although this is a unique proposition the nature of variable rates needs to be taken into due consideration. By using Business Juice we can help can avoid the potentially costly mistake of being exposed to disadvantageous variable rates.To find out more about rollovers visit our Guide to Rollover Contracts.

Terminating but remaining on supply with Ecotricity

If you have provided termination notice to Ecotricity and expressed your intent for freedom of movement at contract end but you fail to leave Ecotricity’s supply you will be placed on Ecotricity’s “Variable Price Plan”.Don’t be caught out! By using Business Juice to manage your energy contracts we will terminate and manage your new contract seamlessly to ensure you avoid unnecessarily costly variable rates.

Ecotricity and Out of Contract Rates

Because Ecotricity operates 28-day contracts with 28-day notice to terminate they do not need to use out of contract rates. Instead a customer will be placed on their standard variable rate until such point as the customer leaves their supply. Where a customer inherits an Ecotricity supply, moving into a premise supplied by them, they will be placed on Ecotricity’s deemed rates which are currently 14.5p/kWh and £3 per day.Even one week exposed to this level of charges mounts up, that’s why clients taking our contract life management service makes sense: removing your exposure risk and letting you focus on your business confident in the knowledge that your energy contracts are in safe hands.To find out more visit our Guide to Out of Contract Rates
