If you’re running a business, energy costs aren’t just a line on a bill; they’re a strategic expense you should optimise. One of the biggest levers you have is when you renew your business energy contract. Get the timing right, and you can avoid overpaying or being caught on default rates. Get it wrong, and your contract might cost far more than it needs to.

In this guide, we’ll unpack the best times to renew, key signals to look for, and how PPS for Business helps clients hit that sweet spot every time.

Why Timing Matters

Energy markets are unpredictable. Prices move based on gas supply, demand, geopolitical events, and seasonal changes, all of which can have a major impact on your renewal rate. The timing of your contract renewal affects:

Market exposure: Locking in during a calm market can secure better pricing than renewing when costs are spiking.
Negotiation power: Approaching the market early gives you the leverage to compare multiple suppliers and negotiate on your terms.
Cash flow predictability: Avoiding last-minute renewals helps you budget more confidently and plan long-term.
Default rates: Missing a renewal deadline often means being moved to an out-of-contract rate, which can be 50–100% higher than negotiated tariffs.

When Is the Best Time to Renew?

While there isn’t a universal answer for every business, some clear trends emerge from the UK energy market:

1. Start Looking 3-6 Months Before Your Contract Ends

This is the sweet spot for most businesses. It gives you time to monitor prices, review multiple offers, and avoid being rushed into a decision. It’s also when many suppliers begin offering renewal quotes, so you can get a feel for where the market is heading.

At PPS, we encourage clients to begin discussions around the six-month mark, even if they don’t commit immediately. That early visibility helps identify when to move.

2. Monitor Market Conditions 6-9 Months in Advance

If your business uses a large amount of energy or operates across multiple sites, start even earlier. The energy market can shift fast, and having a long lead time gives you the flexibility to act when prices dip rather than being forced to renew during a spike.

We often help clients model different renewal scenarios to understand the potential cost difference between renewing now and waiting a few months.

3. Take Advantage of Spring and Summer Stability

Historically, energy prices are often more stable or lower during the warmer months, when demand drops. If your renewal period falls between April and September, it’s often worth securing rates before colder weather and increased demand push prices up again in autumn and winter.

That said, every year is different. Geopolitical or supply chain factors can change the picture. This is why having access to live market insight (like the kind PPS provides) is key.

4. Avoid Renewing in the Winter Rush

Renewing during late autumn or winter usually means facing higher wholesale prices. Suppliers are also busier during these months, which can make it harder to negotiate favourable terms.

If your contract ends in December or January, start exploring options well in advance to avoid being caught in the winter peak.

Common Pitfalls to Avoid

Even with good timing, businesses can still fall into traps that affect their energy costs. The most common include:

Leaving it too late and being rolled onto expensive default rates.
Assuming rates will always drop, which leads to missed opportunities.
Locking in for too long without understanding market trends.
Ignoring non-commodity costs such as standing charges and network fees.
Accepting the first renewal offer from a supplier instead of comparing deals.
