Why do I need to sign a Letter of Authority?

The LOA is what lets us talk to the DNO on your customer's behalf. Here is what it does and does not authorise.

Written by the DNO Renewables teamUpdated

What an LOA is

A Letter of Authority (LOA) is a signed document from the electricity supply owner (usually the homeowner or business) authorising us to:

  • Speak to the DNO on their behalf
  • Submit a connection application
  • Receive the approval and offer letter

Without it, the DNO will refuse to discuss the supply with us. That is a hard rule, not a formality.

Who signs it

The person or company that pays the electricity bill for that supply. Usually:

  • The homeowner (domestic)
  • The tenant (if the bill is in their name)
  • The company director or authorised signatory (commercial)

[!WARNING] Not the installer, not the letting agent, not the landlord (unless they pay the bill). It must be the actual account holder.

What the LOA does NOT authorise

  • Us to change the customer's supplier or tariff
  • Us to modify the physical supply without their knowledge
  • Any financial commitment on the customer's behalf
  • Any credit checks or personal data sharing beyond what the DNO application needs

How the signing happens

  1. You submit the application on our platform
  2. We email a signing link to the customer
  3. They sign electronically in about 30 seconds
  4. The signed copy comes back to us automatically

What if the customer refuses?

Occasionally happens with commercial customers who want to review the wording. Send them our template LOA in advance, or ask their in-house legal to review our standard form. We're happy to talk to them directly.

Reusing an LOA

An LOA is tied to the specific application it was signed for. If a job goes on hold and picks up again months later, or if there's a new application on the same supply, we may need a fresh signature.
