Business energy, explained
What affects business electricity prices?+
Wholesale market conditions at the time you contract, your annual consumption, your meter profile, how predictable your usage pattern is, contract length, payment terms, your location's distribution charges and non-commodity costs such as network and levy charges. Two businesses on the same street can be offered different rates.
Why are business energy contracts fixed?+
Most commercial supply is bought on a fixed-term basis so the supplier can hedge the energy in advance. In return the business gets a known unit rate for the term. Unlike domestic supply, commercial fixed contracts generally cannot be exited early without agreement, which is why the renewal window matters.
When should I renew my business energy contract?+
Most suppliers will price a renewal from around 6 to 12 months before your end date. Starting early gives you time to review options across different market conditions rather than accepting whatever is available in the final week.
What is an MPAN?+
A Meter Point Administration Number is the unique 13-digit reference for an electricity supply point in Great Britain. It appears on your electricity bill, often laid out in a grid, and identifies the meter rather than the supplier.
What is an MPRN?+
A Meter Point Reference Number — sometimes called an M number — is the unique identifier for a gas supply point. It is usually 6 to 10 digits and appears on your gas bill.
