Supplier overview & suitability
SmartestEnergy’s UK site covers electricity purchasing for large businesses, selling generation through power purchase agreements, trading and origination. Customer resources cover billing, moving premises and generator support.
Our assessment: prepare half-hourly data and a buying strategy if you have a large or complex portfolio.
Products, prices & contract checks
Compare a written offer for the same premises, annual usage and start date. Ask the supplier or adviser to explain:
- Contract length, payment method and quote expiry.
- Unit rates, standing charges and any capacity or metering charges.
- Which costs are fixed and which network, policy or other charges can change.
- Renewable certificates or product conditions relevant to your business.
- Any commission included in the price and the scope of the comparison.
Existing accounts, bills & customer support
For a supplier-controlled account, payment, complaint or login issue, use the official route for the company on your bill. Have your account reference, premises address and the relevant bill available.
Customer support — an external supplier resource, separate from Business Utilities UK.
To discuss whether another contract or adviser would better suit your business, contact Business Utilities UK using the call or email panel above. Do not send passwords or payment-card details in an enquiry.
Renewal dates, switching & moving business
Check the end date and notice conditions in your signed agreement. A renewal offer, a contract end and a new supply start are different dates. Tell us if you have already accepted a forward renewal.
For multiple sites, record each meter and its end date. When moving premises, tell the existing supplier the occupancy dates and provide opening or closing readings. Check the process before agreeing supply for a site you have not yet taken over.
Metering, usage & energy management
Bring a recent bill and annual consumption, with half-hourly data where available. Identify the electricity MPAN or gas MPRN and distinguish it from the meter’s serial number. Ask which smart-meter, AMR or consumption-reporting service applies to your premises and whether separate charges apply.
