Back billing and First Utility

First Utility is signed up to the Energy UK Back Billing standards and limits back billing for all SMEs including micro businesses to two years.Many other suppliers have voluntarily limited their back billing rights to two years and in some cases a single year. But First Utility have gone a step further and extended this to all SMEs and not just micro business.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.First Utility therefore provides a strong offer in this area with smart metering reducing the risk, impact and likelihood of back billing.To find out more visit our Guide to Back billing.

First Utility and Letters of Authority

In order to act on your behalf in securing your business a great energy deal First Utility require us to have a signed Letter of Authority from yourselves. You can download your Letter Of Authority here.

Change of Tenancy and First Utility

Moving into or out of a premise is known as a Change of Tenancy in the business energy market. The existing supplier to the premise is obliged to continue to provide energy to the premise and under no circumstances will this be otherwise the case, however it is an obligation on the new tenant to agree a new contract either with that supplier or with a new supplier of your choice.Moving in to a premise supplied by First UtilityIf your business takes occupation of a site currently supplied by First Utility, you need to inform them as quickly as possible that you are the new tenant.This is critical for two reasons:1) to prevent your business being held liable for charges incurred by the previous tenant2) to ensure you can negotiate a competitive rate (and choose to switch if you desire)A Change of Tenancy customer has total freedom of movement and is free to accept a contract with a supplier of their choice. This is good news, however many unscrupulous sales businesses prey on new movers and force them into uncompetitive and unsuitable contracts. To find out more visit our Guide to ScamsIt doesn’t have to be this way. By taking control, informing the supplier of your situation and using Business Juice to secure you the right contract for your business you can take advantage of one of the few re-contracting opportunities outside your renewal window.For your convenience, you can download your First Utility Incoming CoT Letter here.First Utility will also require one of four ‘proofs’ of the change of tenancy having occurred, these are:
  • Confirmation from the landlord or brewery
  • Confirmation from the estate agent handling the move
  • Confirmation from the solicitor handling the move
  • Copy of the mortgage completion letter (if property bought)
By providing this information together with the First Utility Business Incoming Change of Tenancy Letter you can secure your business the opportunity to strike a great energy deal for your needs.Moving out of a premise supplied by First UtilityIf your business is leaving a premise for which you currently have a First Utility Business contract, you need to inform them as quickly as possible that you are no longer the tenant.This is critical for two reasons:
  1. to prevent your business being held liable for charges incurred by the new tenant
  2. to ensure you can negotiate a competitive rate at your new premise
For your convenience, you can download your First Utility Outgoing CoT Letter here.First Utility will also want to know:
  • The reason for your moving out
First Utility may also want to know:
  • To where your business is moving (if applicable)
  • Who the new occupier of the existing premise will be (if known)
You aren’t obliged to provide this information however always ensure you contact Business Juice as an ‘incoming’ tenant so you can save your business time and hassle and exploit the opportunity to strike a great energy deal for your new premise.

When to expect your First Utility renewal letter

First Utility sends their renewal letter to customers around 90 days in advance of the contract end date. This will contain First Utility‘s proposal for your rates for the coming period. It may provide a variety of options or a single price.
