How do I read a business energy renewal letter?

Microbusinesses must receive a renewal notice around 60 days before the end date showing the current rates, the proposed rates, the annual consumption the supplier has used, and what happens if you do nothing. Treat it as the supplier’s opening offer to a customer it expects to keep, not as the only option. Check the end date matches your records, check the consumption figure against real usage, and look at the standing charge as closely as the unit rate, because that is where most recent cost increases have landed. Then put the same supplier in competition with the others on the same start date and term.

How do you negotiate better rates on a business energy renewal?

  • Bring real data. Twelve months of actual consumption, by month, and the meter type. A price built on an estimate is usually wrong in the supplier’s favour.
  • Compete it. The renewal price improves far more often when the incumbent knows other suppliers have priced the same meter on the same terms.
  • Ask about the term. One, two and three-year prices sit at different points on the forward curve; ask for all three rather than the one the letter offers.
  • Ask about the standing charge. Suppliers have more latitude on it than they volunteer.
  • Fix the credit position. A clean payment history and direct debit can change the quote; a disputed invoice can block a switch.
  • Don’t negotiate against a prediction. Nobody can say where wholesale prices go next, and a decision should rest on the annual cost and the certainty you need.

Why did our business energy costs jump so much this year?

Usually one of five things: a fixed contract ended and the account rolled onto out-of-contract or deemed rates; a new fixed contract was priced on a higher wholesale market than the old one; the standing charge rose with network charges, including the increase in transmission charges from April 2026; consumption changed and a tolerance clause was triggered; or a bill error, such as the wrong VAT rate, an estimated read or a missing Climate Change Levy exemption. The first is the most common and the most fixable. Invoice validation covers the errors; out-of-contract rates covers the rollover.

How do you renew business energy across multiple sites?

Line the end dates up. Sites with different end dates are priced on different days and different curves, so the first renewal is often used to co-terminate the estate: shorter contracts on some sites so that everything ends together next time, after which the whole portfolio can be priced as one on one day. Keep a register with every MPAN and MPRN, meter type, end date and consumption, and give the supplier the lot. Half-hourly and non-half-hourly meters are priced differently and may suit different suppliers, which is normal. Multi-site business energy explains how we run an estate as one portfolio.

Can someone handle our business energy renewal for us?

Yes. A broker takes the bill, prices the meters across the suppliers it works with on the same start date and term, shows you the annual cost of each option, serves any notice, handles the registration and keeps the calendar so the next renewal starts on your timetable rather than the supplier’s. We do this from the suppliers on our panel; we are paid by the supplier you choose through a commission included in the price and disclosed on the quote, and we say so when the renewal offer you already have is the one to take. How we are paid explains the model.

Renewal questions

When should I start my business energy renewal?

Four to six months before the end date for a single site, earlier for an estate. Suppliers can price a contract to start when the current one ends, up to around twelve months ahead, so there is no benefit in waiting for the renewal letter.

Do I have to accept my supplier’s renewal offer?

No. It is one quote. You can take it, negotiate it, or move to another supplier, and microbusinesses cannot be asked for more than 30 days’ notice to do so.

What happens if I miss my renewal window?

You move to the supplier’s published out-of-contract rate, or in some larger-customer contracts you are rolled over for up to twelve months at the renewal price. Out-of-contract supply can be left at any time without a fee; a rollover usually cannot.

Can I renew my business energy contract early?

Yes, typically up to twelve months before the end date, with the new rates starting the day the old contract finishes and no overlap.

Are renewal rates negotiable?

Often. Suppliers have most room on the standing charge and on the term offered, and the renewal price improves far more often when other suppliers have priced the same meter on the same terms.

How do brokers help with business energy renewals?

They gather the data, compete the renewal across the suppliers they work with on like-for-like terms, show the annual cost of each option, handle notice and registration, and keep the renewal calendar for next time.
