For many businesses, the electricity contract renewal letter arrives, gets filed, and the new price quietly takes effect. That is usually the most expensive way to renew. A planned business electricity contract renewal gives you time to compare the market, negotiate better terms and avoid being moved onto a rollover tariff.
This guide explains when to start your renewal, how the process works, how to negotiate and which mistakes to avoid.
Why Your Renewal Matters
Your renewal decides what you will pay for electricity for the next one to five years. Small differences add up. For a business using 100,000 kWh a year, every 1p per kWh on the unit rate is worth £1,000 a year, or £3,000 over a three year contract, before standing charges and taxes.
If you do nothing, most suppliers will move you onto a renewal or rollover price. These are rarely the most competitive rates available. If your contract ends with no new agreement in place, you may be charged out of contract rates, which are usually significantly higher. Our guide on what happens when your energy contract ends explains the risks in more detail.
When Should You Start Your Renewal?
Start earlier than you think. As a general guide:
- Six to twelve months before your end date is ideal for most businesses. You can usually secure a new contract that starts when the old one ends, giving you time to watch the market and buy at a good moment.
- Larger and multi site businesses often begin even earlier, because tendering and internal approvals take longer.
- At least three months before is the practical minimum to avoid being rushed.
Many businesses with April contract end dates start renewing in the autumn, which is why now is a busy time in the market. Our article on the best time to switch your commercial electricity contract explains how market timing affects price.
Check Your Notice Period and Contract Terms
Before anything else, find your current contract and check:
- The exact end date.
- Any termination notice requirements. Some contracts require written notice within a set window before the end date, and missing it can trigger an automatic renewal.
- Whether you are a microbusiness. Microbusinesses have extra protections under Ofgem rules, including the right to receive renewal information from their supplier in advance and limits on automatic rollover contracts. Larger businesses may not have the same protections, so the terms of the contract matter more.
If you have multiple sites, list every meter and end date. Aligning end dates at renewal can make future procurement much simpler.
The Renewal Process, Step by Step
- Gather your data. Collect recent bills, your MPAN, annual consumption and, for half hourly sites, your consumption profile.
- Review your current contract. Note what you pay for unit rates, standing charges and any additional charges.
- Decide your priorities. Price certainty, contract length, renewable supply, flexibility or a combination.
- Compare the market. Obtain quotes from several suppliers, not just your current one. For larger requirements, a formal tender works best, as explained in what happens during a business electricity tender.
- Compare like for like. Check whether network and policy costs are fixed or passed through, and compare the total annual cost rather than just the unit rate.
- Negotiate and sign. Prices are often valid only for a short time, so have approvals ready before quotes arrive.
- Serve notice if required. If you are switching supplier, make sure any required notice is given correctly.
- Diarise your next renewal as soon as the new contract is signed.
How to Negotiate a Better Renewal
- Use competition. A supplier’s renewal offer is more competitive when it knows you are comparing the market.
- Know your numbers. Accurate consumption data leads to sharper pricing and fewer surprises.
- Consider contract length. Longer contracts can secure a good price for more years, while shorter terms keep options open if you expect prices to fall. Our guide to fixed vs flexible energy contracts looks at the trade offs.
- Look beyond the unit rate. Standing charges, payment terms and billing arrangements all affect the real cost.
- Ask about green options. Renewable backed contracts may cost little extra and support your sustainability goals.
- Get expert help. A broker can approach many suppliers at once and knows where the market is moving.
Common Renewal Mistakes
- Leaving it until the renewal letter arrives.
- Accepting the incumbent supplier’s price without comparison.
- Missing a termination notice window.
- Comparing unit rates only.
- Letting quotes expire while waiting for sign off.
- Forgetting smaller sites or secondary meters.

Frequently Asked Questions
How early can I renew my business electricity contract?
Many suppliers will offer prices up to a year or more before your current contract ends. Starting six to twelve months early usually gives the widest choice and time to buy at a favourable point in the market.
What happens if I do not renew my business electricity contract?
Your supplier may move you onto a rollover contract or out of contract rates, which are usually more expensive than negotiated prices. Planning your renewal early avoids this.
Do I need to give notice to leave my current electricity supplier?
It depends on your contract. Some contracts require written notice within a set period before the end date. Microbusinesses have additional protections, but it is always worth checking your terms well in advance.
Can I negotiate my business electricity renewal price?
Yes. Suppliers are more competitive when they know you are comparing the market, and accurate consumption data, flexible contract lengths and a broker’s supplier access can all help secure a better price.
Should I renew with my current supplier or switch?
Compare both. Your current supplier may offer a competitive price, but you will only know if you compare it against the wider market on a like for like basis.
