Back billing and SmartestEnergy

We are awaiting SmartestEnergy's policy on back billing. Many suppliers have voluntarily limited their back billing rights to two years and in some cases a single year. However equally a number of suppliers are not signed up to the Energy UK Back Billing standards and therefore, under the Limitations Act, are able to back bill their customers for anything up to 6 years. To find out more visit our Guide to Back billing.

SmartestEnergy and Letters of Authority

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

Change of Tenancy and SmartestEnergy

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 choice There 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 supplier Thirdly, 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 Lloyd Energy 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.

Rollover Contracts and SmartestEnergy

SmartestEnergy does not operate a policy of auto-rollover contracts. Now, when as a SmartestEnergy customer, your contract comes to an end, if you have not contacted SmartestEnergy or have not accepted their renewal offers you will simply be placed on their '"Out of contract" rates. The "Out of contract" rates will be more expensive than a "Fixed Price Plan" but it will allow you to leave at any time. Of course it makes sense not to get to this point in the first place and so contracting well in advance is always recommended as even a short term stay on a "Out of contract" rates will be significantly more expensive than other options. At least however you can be safe in the knowledge that if you do make a mistake and fail to contract properly the cost of your error can be minimised. However by using Lloyd Energy you can avoid the potentially costly mistake of being exposed to variable rates. To find out more about rollovers visit our Guide to Rollover Contracts.

SmartestEnergy and Out of Contract Rates
