Thirty days is enough time to secure a new business energy contract, as long as you start comparing this week rather than waiting for the renewal letter to decide for you. A broker with access to several suppliers is usually the quickest route, though going direct or negotiating with your current supplier can also work. Missing the window often leaves you on rollover or out-of-contract rates, which tend to cost far more than a fixed deal. Below are eight services and routes that can move fast, chosen for their speed to quote, their spread of suppliers, and how much of the legwork they take off your plate.
1. Utility Bidder
Utility Bidder compares business gas and electricity from more than 25 UK suppliers and says quotes can be produced within minutes. It suits busy owners with a deadline who want someone else to run the comparison and lodge the switch, with a dedicated account manager handling the paperwork. It is free to use, as the broker earns commission from the chosen supplier. Its typical claim is savings of up to 35% compared with out-of-contract rates. The caveat: as a broker, it compares its panel of suppliers rather than the entire market.
2. Your current supplier’s renewal team
Your existing supplier already holds your meter data, so a renewal can be agreed in a single call. This suits businesses happy with their service and keen to avoid any switching admin. Ask for the renewal quote in writing and query the standing charge line by line. The limitation is obvious: you are negotiating with only one party, and the opening renewal offer is rarely the best one available.
3. Bionic
Bionic is a well-known UK broker that covers energy, broadband and insurance. It suits small firms who want to sort several bills in one conversation. It has the scale to turn quotes round quickly when you have meter numbers and a recent bill to hand. As with every broker, results depend on its supplier panel, and you should ask for commission to be disclosed, which Ofgem rules now require for microbusinesses.
4. Exchange Utility
Exchange Utility is a business energy broker that works with SMEs and larger companies. It suits owners who want an adviser to talk through contract length and whether to fix for one, two or three years. The caveat is the same as for any intermediary: you see the prices it can access, so compare against at least one other source before you sign.
5. Business Energy Comparison
Business Energy Comparison is an online-first service that lets you enter your details and see tariffs without much back and forth. It suits owners who prefer to research quietly before speaking to anyone. Speed depends on how quickly you supply accurate meter data. The limitation is that online results can be indicative, and the final contract price may change once the supplier checks your credit.
6. Octopus Energy for Business
Octopus Energy for Business sells direct and suits small sites that like a clear online sign-up. Its business tariffs include fixed and flexible options, and its service reputation is generally good. Going direct cuts out the middle step. The trade-off is that you see one supplier’s price only, which is fine for a sense check but not a full comparison.
7. British Business Energy
British Business Energy is a UK broker focused on small and medium businesses. It suits sole traders and small limited companies wanting a quick phone-based comparison. The caveat is that, like other brokers, its prices reflect the suppliers it works with, so treat its quote as one data point.
8. Send a termination notice now
Whatever route you choose, check your contract’s notice period today. Many business contracts require written notice before the end date or they roll onto new terms automatically. Sending notice protects your options while you compare. The limitation is that notice alone does not secure a new rate, so pair it with a signed contract before the end date.
How to choose
- Find your contract end date and notice period first.
- Have a recent bill, MPAN and MPRN ready for every quote.
- Compare standing charges alongside p/kWh unit rates.
- Ask each broker to disclose its commission in writing.
- Check credit requirements before you assume a quote is final.
Send written notice to your current supplier today, then line up two comparisons this week. That leaves time to sign before the end date rather than after it.
